Strobe Lighting has been used in the police cars since 1960s. It is commonly called as strobe, which originated from a Greek word “strobos” that means “act of whirling”. Strobe light or stroboscopic lamp is a device which produces regular flashes of light. They have many uses in industrial and scientific applications but are mainly used in the night clubs where they provide an illusion of slow motion. Some other common uses are in alarm systems, in theatre lightings, in navigation lights, in aircrafts anti collision lighting and most useful in emergency vehicles. Police Strobe Lights have become very popular. They are the main source through which the police vehicles can draw the attention of other vehicle’s drives in the heavy traffics on roads.
Police Strobe Lights commonly use xenon flash Lamps as their light source that has a complex spectrum. They require colored gels or casings in order to get colored light. They can also be used as a stroboscope. They need just milliseconds to start and give flash power of several kilowatts. They consume less energy. They can be used in continuous mode and large version to produce extreme high illumination.
Police Strobe Lights are used to produce regular flash lights with the use of halogen lamps. At present time they are replaced by LED lighting technology because of their better intensity with very low power consumption. Some strobe lights can flash around hundred times per second after being calibrated but it can be used in very few cases as they can cause photosensitive epilepsy. They can increase the seizures in case of photosensitive epilepsy. Most of the Police Strobe Lights are used with low flash rates which do not go more than five flashes each second and also the strobing effect can not continue for more than thirty seconds. These rules however are not applicable for emergency vehicles like police vehicles.
Police Strobe Lights are of several types like: Alarm or Emergency lights, Magnetic strobe lights and Strobe bars. They are available in many colors that include amber, blue and red. The strobe lights are also available as decoration based that is used off the road. This Type of strobe light uses LED or halogen lights. The most important part of this light is that a control box is attached with it that helps to change the frequency and pattern of the flash. It can be changed to normal or strobe light according to use. The decoration based strobe lights are available with several color filtered plates and so color of the strobe can be changed easily by changing the plates.
Police Strobe Lights are replaced by LED with time as they themselves replaced the Halogen Lights. They are used as an emergency signaling device. They include many types like: Strobe Lights, Warning Lights, Emergency LED Lights, Amber Warning Lights, Beacon Roof Strobe, Emergency LED Strobe Lights, Light bars, Strobe Beacons and many more. The strobe lights of blue color sometimes hurt the Night Vision of the police officers. The colors are set according to the laws of the states. The light bars control the direction of activation of the blue lights and thus help them to avoid accidents. In cases where LED strobes are used this is a major problem as they are of very high brightness and luminosity and thus affect the vision of the officers driving the vehicles. But in spite of all these problems these strobe lights are very helpful for police vehicles. They serve as an alarming signal and help to warn people and reach to the required spot and fast easily. They also help them to move smoothly in the heavy traffics.

Fiber optic cables are pretty amazing little gadgets! A fiber optic cable works by light being transmitted through the core part of the cable. The light bounces back and forth from one side of the cable to the other side, as though mirrors were set on opposing sides. The light is able to move because it keeps being bounced back and forth between the sides without absorbing more light in the actual...

Is there a slave flash sensor that can be attached to the front of the built-in flash to receive cam flash?
I'm looking for an external flash for my FZ18.
Is there a model that has a sensor attached on the build-in flash to be triggered when cam flash fires?
Any model do you want to recommend?
They are called "Slave flash". You can do your own research on them by searching for that term.
They don't have to attach anything to your camera, they have this little sensors on them that detects flashlight, and they'll fire as well when they detected that your camera fires off flash.
This also means that if someone beside you is taking a picuture with flash, your slave flash will go off as well.
I can't recommend a model since I don't have one myself, but if purely just look at the brand, I'd say get one form Metz, like this:
Wireless trigger for studio strobes, mono light and flash;
Micro-computer control;
Triggering delay is 1/1600 second;
Two channels that work without interference with each other;
Receiver searches channels automatically;
Long lifetime of trigger battery, one year or over 20,000 continuous triggers;
Receiver uses two AAA batteries (not included) with power switch;
Working indication: LED;

Khazars had my phone in my bag and my bottle of water infiltrated everywhere. Now the phone will not turn and was told that if the point inside the Cover is red (is), then no water damage. I have no insurance on the phone and not Verizon have pricing (because it was my fault), but nobody knows whether this means that the phone is now irretrievable? I decided to let it dry and see what happends but I fear there may be a lost cause. Thank you!
You can try removing the battery and the phone disconnected blowdrying, but more likely to screwed. You can try calling Verizon and called for insurance for your phone that will remain a copayment of $ 50 to replace, but as the phones, which normally costs $ 2-300 if you are in the contract. But I think they call you by phone to make sure you arent trying to get insurance after the fact (as it would). Apart from that, no, Verizon custom fix if there is a red dot. * You can try to peel the label off, and go there and play dumb, but probably will understand. Empty water damage all warranty claims, which are used again most likely try to fix it (I know not ...) If you are a little on his contract, may be more advantageous for you to add another line to his plan of $ 10 per month to pay $ 300 for a new phone, you must cancel your Original line once the contract is up (which is what we did with the phone my mom). But more often than not, the water damage is irreversible. For future reference, if something is damaged by water, remove the battery as soon as possible. Short-circuiting the battery is that usually fries the phone, so the phones are off and damaged by water, they sometimes get a little better.

Scaled bike version have created a new trend in the market. In the past, the bicycles used in high Speed and heavy weight. A Mini Chopper is built using a small tube, and some sections of black steel pipes. A mini chopper bike is a bike that is capable of application today. These bikes are now on the market because they can be designed in less time with a discount. Horizontal or industrial Tecumseh Briggs & Stratton engine are few special motors used for building a mini factory. Furthermore, the two engines of some other engines small engines, such as dirt bike engine motorcycle and ATV are also used in mini-cutters.
In General, a small engine is used in a Custom mini chopper. If you use a professional motorcycle engine, must be a transfer back to support the rear wheel. The People who build mini choppers use centrifugal clutches. These clutches play an important role in maintaining the fixed gear ratio. In addition to the reference axis of the clutch can also be used in the construction of a mini chopper. Intermediate shaft makes work the application of machinery easy. This tree allows riders to change gear ratio to its desirability. Bicycle or motorcycle wheels are used to design a mini chopper. A series of mini mopeds tire or ride bicycles in front of a mini chopper. Larger tires are mounted on the back of the mini chopper.
Some people who want to use alloy wheels for its unique modern mini chopper. 205/20-10 wheels or wheel golf cart is equipped to give a real to it. The axes are commonly used in mini cutters. Live in the direction of rotation of the wheel axle, and other parts. Convenience is the main motivation of an engineer who has designed a mini chopper. Parts like disc brake rotors, wheel hub, art, etc. attached to the axle with locking clamps or screws. Parts of a mini chopper are loosely attached to the bicycle so that it can be easily removed if need be. Mini Chopper is beautiful, is ideal for middle class families to use and display.

I was wondering what size softbox or umbrella would you professional photographers recommend to someone who is a hobbyist looking to take portraits of their family. I have 2 Strobes and am just trying to figure out what size softbox or umbrella I should get to take head shots, 3/4 shots and full length shots of individuals in my family and my family all together.
This can actually be a somewhat difficult question to answer.
The key is not the size of the umbrella(s), but rather the Type of lighting you desire combined with the even-ness of coverage.
The most important factor in the equation is the size of your family. (Both figuratively and literally!) A family of 3-5 average-sized people might be easily covered by two 36-inch umbrellas, provided that they're on adequately-powered lights. However, a family of 4 "big-boned" people (or just plain fat) will naturally have to sit farther apart. And so on.
To be honest, I think that for a Good family portrait you're going to need more lights. You'll want a Background Light, and 1-2 backlights (aka, rim lights).
Softboxes would probably prove to be a bad idea, because it will be hard to keep them at an even distance (unless you buy REALLY BIG ones), so I suggest using 36-inch umbrellas.
As an alternative, I would suggest using two large pieces of white foam board as reflectors, and setting the lights up bare. Aim the bare lights from behind, as if they were rim lights, and then use the foam boards as reflectors in the same way that you would have used umbrellas. In this way, you're kind of getting four lights for the price of two. And your total investment in two large pieces of white foam board should be less than $10.

Flash Photography Techniques – Ambient Light Plus Flash
With careful use of flash, you can make your photo looks natural as though no flash had been used, instate it will enhance the photo further reducing contrast and yet looking very natural.
It has been a dream of all photographers to look for the balance in lighting whenever they photograph a subject and most of the time the quality of available light isn’t always perfect. I will share my experience in making use of flash wisely I am able to enhance my photo rather than by just using the available ambient light.
Before we get started let me clarify a few things with regards to my flash photography techniques that I will be sharing with you.
Let me define the term flash in this article - it is what some people call “Speedlight” which is the add on flash mounted on the camera hot - shoe Type and not either the studio strobe type of flash or the pop–up flash build in the camera..
The flash photography techniques I’m writing in this article are mostly applicable for “on the field” or “on the move” photography and not studio photography.
I’m a user of Nikon D-SLR and Speedlight, some example of my photography work shown here are not a standard recipe as each camera system may have a slide different reading hence require some slide adjustment.
Ambient Light plus Flash
I use flash most of the time but using flash does not mean you will spoil the ambient light thus making the photo looking unnatural. Why just use available light alone if your photograph turns out to be horrible. I will show you by understanding some essential techniques, mixing ambient light with flash you can make a better image.
By using the flash I will be able to highlight the shadow areas and avoid shadows under the subject’s eyebrows thus making it a better photo than it would have been without flash. But this does not mean that the image will turn up flat. Make sure you get your reading right.
Let’s try two examples:
1. A wedding couple on a beach and under a tent as the sun is going down:-
Shoot in manual mode because you need to be in control of your exposure metering for accuracy and consistency.
Meter for the ambient light, get your exposure right, turn off your flash and take a test shot. With the correct exposure you will get a perfect natural surroundings but the wedding couple will be little under exposed or with some shadows around their faces.
Now turn on your flash and adjust your flash to Ttl-BL mode which balance flash automatically with ambient light (as I’m using Nikon). Adjust your flash compensation. Start from 0 EV compensation and slowly go up until plus 1.7 EV. How much is enough? There is no one correct answer to that as it depends how much flash you need to use as a fill in flash. In this example you surely need a stronger fill-flash to match the sunlit background.
Flash was turn off. I took the reading of the ambient light and took a test shoot. Satisfied with the overall exposure and then on my flash light and took the photograph below with my flash light firring direct and dial up the my flash up to +1.7 EV. See the photographt below for comparison.
2. Portrait of a couple against a wall
Again always shoot on manual mode.
Meter correctly for the available light.
Adjust your flash to TTL-BL mode. As for out door, I usually start from -1.3 EV because Nikon Speedlights on TTL-BL mode balance flash automatically with ambient light and I will always shoot with flash firing straight on. The real idea is to use the flash as a fill-light only and to lift the shadows.
- Notice with a fill flash I manage to eliminate shadows under the couple eyebrows without overexposing the wall and the couples’ clothing’s.
Photograph 2 - Shoot using flash
The above two examples clearly tells you by just adding flash with the correct exposure set by reading the ambient light together with the right amount of flash value to be fired you will have a perfect and balance natural looking image. Who says by using flash it will look unnatural and spoil the ambient light?
I will be following up with an article entitle Flash Photography Techniques – Bouncing the Flash next to share my photography experience with you. By bouncing the flash you are able to soften the light and reduce or eliminating flash shadow.

Bluetooth is a wireless technology that allows personal computers, laptops, cell phones and other Bluetooth enables devices to communicate with each other Over short distances of about 10 meters to transfer information/files from one device to another. Bluetooth uses radio waves and is designed to be a secure and inexpensive way of connecting and exchanging information between devices wirelessly.
Following are a few of the most informative Bluetooth facts from a arsenal of thousands.
Fact # 1: "Bluetooth refers" to Harold Blatand who was the tenth century Danish king and unified the Norwegians and Danes.
Fact # 2: The renowned Andretti Green Racing team communicated during the race using Bluetooth devices
Fact # 3: According to a research the Bluetooth device users was expected to rise more than one billion by the year 2006.
Fact # 4: Analysts predict that one third of all new cars in the world will have built-in Bluetooth connections.
Fact # 5: A lot of latest Bluetooth medical Equipment are being manufactures and deployed by hospitals to enhance the patient care.
Fact # 6: Latest Bluetooth enables devices let you watch images on your TV screen. This can be achieved using laptop or mobile phone over a Bluetooth connection to a media viewer.
Fact # 7: Printing can be done wirelessly now! One can send files to print from Bluetooth enables computer or mobile gadget directly to printer with Bluetooth interface. There are also small home use printers that just print out color pictures by taking wireless Bluetooth input from cell phone or computer.
Fact # 8: The latest Multi point pairing Bluetooth enabled interface lets you connect with more than one Bluetooth devices, for example your cell phone can be connected to Stereo Bluetooth headset and your computer at a time
Fact # 9: One of the fastest growing Bluetooth devices in "Bluetooth hands free" and the second largest overall application, just behind the hands free is "Bluetooth stereo audio".
Fact # 10: Extensive Bluetooth usage is hazardous for health. Bluetooth uses microware radio waves with the frequency range of 2.4 GHz to 2.4835 GHz and the power output from a Bluetooth radio is 100 mW, 2.5 mW, and 1 mW for class 1, class 2 and class 3 devices respectively. The class 1 is almost at the same level as cell phones are, whereas class2 and class 3 are much lower than class 1 and considered less of potential hazard then cell phones.
Fact # 11 Future of Bluetooth is expected to have Bluetooth information points for broadcasting channels, this will start the real usage of Bluetooth inside the mobiles and enable advertising models based around users pulling information from the info points, and not based on current limited object push model. One of the best bluetooth stereo headsetcompanies which is expected to excel in this field is Motorola and Blackberry
Fact # 12 The latest Bluetooth devices can now play a role of the "master" and can communicate with up to a maximum of 7 devices as "slave". This group of 8 devices (1 master + 7 slaves) is called a Piconet. At any given time, data can be transferred between the master and 1 slave; but the master switches rapidly from slave to slave in a round-robin fashion to see for any further file transfer request.

The Home Photographer - When is a Tripod Really Necessary?
The average home photographer owns a point and shoot digital camera. These devices are capable of capturing Great images and many even allow users to select an appropriate scene mode to make automatic exposure and shutter Speed adjustments without the hassle of true manual controls. In some shooting situations however, adjusting the camera settings, automatic or otherwise, may not be all that is needed for a great shot.
In many instances a steady camera is necessary, especially when shutter speed is adjusted or minor movements can be accentuated. Simply put, a camera tripod becomes more of a necessity in special situations which the average user may encounter.
1. Night time Shots
When shooting at dusk or at night, available natural lighting is obviously reduced. A flash is extremely limited in its range and is generally not a Good tool to use in such situations. To get more light into the lens, the camera will adjust exposure and perhaps shutter speed when set to the Night setting. With a slower shutter speed comes the risk of introducing more camera shake which results in unwanted blurring. Using a tripod during shots taken with a camera set on the Night setting reduces the inadvertent camera movement and improves picture quality.
2. Close up Shots
For those who wish to photograph objects, insects, or other items within just a few feet, the risk of blurring is also increased. Minor movements that might otherwise be imperceptible become much more evident in the resulting image. Again, using a tripod can help to reduce unwanted movement of the camera although care must also be taken to assure the subject and items in the background remain stationary as much as possible.
3. Self Portraits
Many point and shoot Digital Cameras allow the user to set the timer in order to allow them to include themselves in shots. This is a great feature but certainly getting a level and steady surface for the camera to rest on is critical for good quality image. Again, use of a tripod is the best bet. Aside from stability and a level surface, a tripod offers adjustable legs and a head that allows further movement to assure that framing is perfect for the shot.
4. Action Shots
Not all action shots require a tripod but if the user wishes to pan with the movement it certainly makes the task much easier. Panning without a tripod is certainly possible but requires some practice. Camcorders, even more than cameras, benefit from the use of a tripod in such instances.
5. Enlargements
Many shots may look good initially but when enlarged any imperfections can be accentuated. This is certainly true with any blurring. What is either imperceptible or minor in a 4x6 print may be a significant defect in an 8x10 enlargement.
Home photographers may have a great digital camera but a tripod is often a tool that turns mediocre pictures into the clear, outstanding images that draws the acclaim of friends and family.

In our last article, we looked at using graphics in e-Learning. Now, we’ll examine another important tool for creating successful course interactions – Adobe Flash™. Flash is a vector-based animation and interactivity program that allows you to create everything from simple animations to complex interactive applications. With its built-in programming language – ActionScript – Flash is fully scriptable and can communicate with several backend database languages. Since the first Flash product appeared (from Macromedia), the e-Learning community has worked with Flash developers and engineers to make Flash content more and more accessible in e-Learning environments.
With its feature-rich list of capabilities, built-in components, and e-Learning output templates, Flash makes a lot of sense for maximizing course content. In this article, we’ll highlight some of the important features of Flash and how they can make your courses shine.
1. Animations for Step-by-Step Procedures
In 10 Tips for Using Graphics in e-Learning, we saw the importance of using graphics in courses, to strengthen how well they meet learning objectives. We talked about different delivery methods for conveying subject matter, and one of those methods was animation. Flash uses timeline-based animation, which makes it quite easy to build animated movies. Graphical elements may be created directly in Flash, but a majority of developers use other tools that they are more comfortable with – especially Adobe Creative Suite. With Flash CS3, you can now import native Adobe Illustrator and Adobe Photoshop files. You can even convert “layered” files from these programs into Movie Clips and animate the individual layers using keyframes in the timeline.
In e-Learning materials, step-by-step procedures can be particularly tricky. Think of the last piece of furniture that you had to put together. How useful were its instructions? One of the things IKEA does well is its non-text instructions for assembling its furniture. These instructions are pure imagery. Take that concept a step further, and you have animation. An animated step-by-step instruction is much more powerful than static imagery. During an animation, you can highlight specific areas, use animated arrows, and express a learning objective much more naturally and effectively.
When the American Contract Bridge League (ACBL) asked SyberWorks to produce a series of courses for its Bridge-playing members, we used Flash to create animated card-playing sequences, and to illustrate specific turns in games. The card images were prepared in Adobe Illustrator, imported into Flash, and converted into Movie Clips. Using scripts provided by ACBL, we created animations for each play, to illustrate the rules that it represents. Other graphical and text elements were added in Flash to point out parts of the animation. These courses are now delivered to hundreds of Bridge players across the country.
2. Easy Audio Integration
Adding audio to an HTML-only course presents difficulties for course developers. First, multiple audio formats are available on the web today: WAV, AIF, MP3, M4a, etc. Even worse is the vast array of audio-player applications and their file-Type associations, both for Mac and Windows platforms. Having users download specific players is a distraction from the course material, and a potential source of additional problems.
Flash, however, supports several audio formats and plays them all using the Flash Player, which has a 98% market penetration. The Flash Player is available in all major browsers and platforms, and is even becoming available in more Internet appliances. You can easily import almost any audio file, add it to the Flash timeline, publish the Flash movie, deliver the course, and be fairly certain that users will be able to hear the audio without having to download an extra player.
Another problem with audio is that, if a sound file is not set up to “stream,” there is a chance that some of the sound may drop out. Flash has built-in streaming capabilities, so you can be assured that your audio content will be delivered to users without drop-outs and gaps.
At SyberWorks, we use Flash for in-course audio content. Audio is recorded in our audio lab and saved in a common format. The file is then imported into Flash. ActionScript is used in conjunction with on-screen buttons, to allow users to control audio playback. This interactive audio file can then be attached to any course, using the SyberWorks Web Author application.
3. Course Navigation
How smart is your course navigation? By “smart,” I mean can it communicate with your LMS? Most in-course navigation is pretty boring and perfunctory. If you spice up yours with Flash, your courses will become more useable.
Since Flash can work with SCORM and AICC courses, on-screen buttons can be scripted via ActionScript to send calls to the LMS for certain conditions. A button at the end of a lesson might send a finish statement to the LMS, signifying lesson completion and triggering further actions. Another button might automatically submit the results of a quiz.
Better learning experiences are possible, since the entire interface is completely customizable, and buttons are very easy to create in Flash. If you want, you can even use its built-in library of buttons to create your course navigation.
At SyberWorks, we retro-fitted some existing e-Learning courses (developed for restaurant employees) for our LMS, complete with all of the calls necessary for course status and completion. These Flash-based courses had a cohesive look and feel that was much more compelling than a plain-text HTML web experience.
4. Creating Simulations
Some software tools, such as Camtasia and Captivate, are designed solely for creating software simulations. They have advantages and disadvantages, and SyberWorks does use them, along with other simulation software packages. But what if the software you need to create a simulation for isn’t available on your platform, or only works behind a client’s firewall?
When the Palm Pilot came out, I had the opportunity to create a software simulation that showed new owners how to use the device. Since the Palm software only resides on the Palm Pilot, I couldn’t use a PC-based software-simulation tool to capture screens. So I used my scanner and Photoshop, imported the screens and artwork into Flash, and created the simulation.
At SyberWorks, we are currently working with an Internet company whose proprietary software (for security reasons) only works on computers behind their firewall. Since we can’t install or use their software in-house, we had to go to the client’s location to take screen shots. Those images were then imported into Flash, captions and highlights were added, and the course material came to life.
5. Video
Video is becoming more prevalent on the web these days, with the rise of YouTube and other video-streaming services. Video can significantly enhance course materials, but (as with audio) it can be difficult to manage, due to multiple video formats and players. On the PC, AVI is the dominant format and Windows Media Player is the usual player. On the Mac, MOV is the format of choice and the Quicktime Player from Apple is the dominant player. However, there are other video formats and players, including Real media / Real Player and others.
When Flash MX 2004 was released, video was a major component. And with Flash CS3, video has become even easier to incorporate. You can deploy video on your own server or on a dedicated Flash Streaming Video Server, for extra bandwidth. Flash has its own video format, called Flash Video (FLV). Flash videos can be played by any Flash movie (SWF) file, so no additional player is necessary. In fact, a majority of the movies found on YouTube were done in the Flash video format.
A short demonstration video, not longer than 1 minute, can be embedded in a Flash movie. Anything longer than that can be linked to a Flash movie file and set to progressively download from your server. If you are expecting a lot of traffic and have longer movies, you should use a Flash Video Streaming server. There are many of these FMS services out there, and SyberWorks uses UpStream Networks to host our larger videos.
With Flash and ActionScript, it is also possible to do more than just play videos. Cue Points can key off of specific video frames, to control other events. And the new captioning feature can add closed captioning for video segments. At SyberWorks, we created a video of a speaker presenting a slideshow. Cue Points in the video triggered relevant text to appear, and made it seem that the viewer was actually on-site, watching the Original presentation.
But keep in mind that video is processor-intensive. Consider your audience and the minimum system requirements necessary to view streaming Flash videos. Dropped frames and inconsistent playback can occur on slower machines.
6. Drag-and-Drop Interactions
A simple multiple-choice quiz can be effective in testing situations, but drag-and-drop interactions can add many useful features of an interactive process. With drag-and-drop interactions, you can simulate experiences that mimic the real world.
Using Flash and ActionScript, drag-and-drop interactions can be created from scratch, using hitTest properties and if conditionals to test whether an object has been dropped on a specific target. If the object has landed on its correct target, the application shows a correct response or visual/audio feedback. If the object is not dropped on its correct target, an incorrect response or visual/audio feedback can occur.
In Flash, you can access built-in drag-and-drop (and other) interactions, by going to the Window menu, then to Common Libraries, and then to Learning Interactions. The interactions are ActionScript 2.0 only, but have all of the features necessary to create many desired interactions. You can then use the Flash Component Inspector to configure interactions, change their text, and alter the conditions of their tests.
At SyberWorks, we created drag-and-drop interactions to meet the many custom-content needs of our clients. Doing a custom application gives us complete control Over both the look and feel of course environments and the parameters of their interactions. Audio also helps to give user feedback for every action, and a final screen tells users how effectively they completed the exercises.
7. Components
Flash comes with ready-made user-interface components that you can add to courses and configure through the Component Inspector and the Parameters panel. These components include: Radio Buttons, Checkboxes, Text Fields, clickable Selection Buttons, List Boxes, and Combo Boxes. Components in Flash CS3 are easier than ever to customize; simply double-click on a component and edit its “skin.”
ActionScript can call on a specific object and test whether its condition matches a Boolean value, as in a Radio Button or Checkbox. You can even use ActionScript to test for specific conditions and return certain values, to create your own quizzes and test interactions.
You can also dynamically update the text for components from an external text file. So application development is much easier now, using Flash Components and ActionScript.
8. Dynamic Text
As mentioned above, Flash lets you pull text into Dynamic Text fields. You can import variables from a simple text file, or load text from an HTML or XML file. Flash CS3 has expanded its capabilities to handle XML files, with E4X.
You can also use a loader object to bring external text into text fields. This loader object has specific conditions that when met, will display text when the loading is completed (or display an error message if a problem occurred). Dynamic text can be formatted through an external CSS file, or using simple HTML tags. But any text field that will be accepting dynamic text should have all font characters embedded or set to a system font.
The major advantage of using dynamic text is flexibility. When the content of your application changes, it’s much easier to change an external text file than to change text embedded in a Flash file. Text that is imported dynamically is cached by the Flash Player, so be sure to clear your cache when you update the content of your app.
9. Built-In Quiz Templates
In addition to its built-in learning interactions, Flash also offers Quiz templates. Simply go to File, then to New, and in the Templates section, select the Quiz category.
There are three Quiz styles to choose from. At the left of the stage, a Control component provides instructions and is governed by the Component Inspector. You can make adjustments to the entire Quiz and choose result options. Each frame in the Quiz template has its own set of learning interactions for you to choose from. So when you need a multiple-choice question, you can copy and paste the frame for multiple-choice questions and modify it as needed.
It’s very easy to set up a Quiz from this template. And by default, the Publish settings are set to SCORM 1.2, for sending the template’s Quiz results to an LMS. We’ll talk more about that in the next section.
10. Built In SCORM/AICC Support
Flash supports the SCORM 1.2 and 2004 standards, as well as AICC. Any application that you develop in Flash (that needs to communicate with the SyberWorks LMS) must be “published” using these templates. Go to the File menu, and then to Publish Settings. Click the HTML tab and choose the appropriate template for the type of tracking you want.
In an HTML file that has been published by Flash, you will find a large JavaScript file, containing all of the functions and variables necessary to populate the Application Programming Interface for the LMS. There are also functions for connecting Sharable Content Objects with the LMS.
But keep in mind that Flash does not generate a manifest file for its published content. So you may need to use an external manifest application to collect all of the components in your application, for upload to an LMS. (A manifest file is a library of all of the assets required for a course, including SCO’s, HTML, SWF, and other files.) The SyberWorks LMS supports all SCORM 1.2- and AICC- compliant courses, and our customer-service representatives can help you configure your manifest files, for hosting on our LMS.
Summary
If you want to give your courses a lot more zing, Flash is a perfect tool for building richer learning experiences. Custom Flash development may take longer than traditional course development, but the extra time it takes is more than offset by improved, more interesting, learning experiences for students.
And with Flash, you never need to worry about students being able to view your course materials, including audio and video. Built-in components, learning interactions, and quizzes, plus support for SCORM and AICC standards, make Flash an attractive choice for creating compelling e-Learning courseware.
