How the VKB works?
Step 1: Template creation (Projection Module)
A template of the desired interface is projected onto the adjacent interface surface. The template is produced by illuminating a specially designed, highly efficient holographic optical element with a red diode laser. Note: the template serves only as a reference for the user and is not involved in the detection process. In a fixed environment, the template can just as easily be printed onto the interface surface.
Step 2: Reference plane illumination (Micro-illumination ModuleTM)
An infra-red plane of light is generated just above, and parallel to, the interface surface. This light is invisible to the user and hovers a few millimeters above the surface. When the user touches a key position on the interface surface light is reflected from this plane in the vicinity of the key and directed towards the sensor module.
Step 3: Map reflection coordinates (Sensor Module)
Reflected light from user interactions with the interface surface is passed through an infra-red filter and imaged on to a CMOS image sensor in the sensor module. Custom hardware embedded in the sensor chip (the Virtual Interface Processing CoreTM) then makes a real-time determination of the location of the reflected light. The processing core can track multiple reflection events simultaneously and can thus support both multiple keystrokes and overlapping cursor control inputs.
Step 4: Interpretation and communication (Sensor Module)
The micro-controller in the sensor module receives the positional information corresponding to the light flashes from the sensor processing core, interprets the events (e.g. keydown, keyup, mouse or touchpad control etc..) and communicates them through an appropriate interface to external devices.

I got my unit and i cannot connect it to Samsung i730?
Your Samsung i730 uses the Microsoft Bluetooth Stack. Though the i730 icon is not on the CD, it uses the same driver, and instructions as the i-mate Jam (a.k.a. as Dopod 818/XDA Mini). So...
a. INstall this driver (to check that you have the right driver installed, open the driver, goto VKB->About. Should say at the top V5.0c.b. Turn on your Keyboard. Press Shift-Fn-B for about 2-3 seconds until hearing a beep (your keyboard is now ready for pairing...).c. Tap the VKB Programd. Tap the Connection tab and select Bluetooth from the Virtual Keyboard on dropdown box.e. Press the Search button.f. Upon completion of the search, the drop down list of devices should be filled with VKB Keyboard.g. Tap the VKB tab and check the Enable Keyboard checkbox.h. The software will prompt you for a Bluetooth passkey; Using the keyboard on the screen of the i730, enter a passkey of between 1 and 8 digits (one digit is enough, I always use "9") and then tap Initiate Pairing.i. Listen for the �beep� on the Virtual Keyboard, then, using the keyboard projected by the Virtual Keyboard repeat the passkey and press return [8].j. The blue LED will go on to show your successful connection. You are now ready to use the keyboard.
Does the VKB (bluetooth) work with windows mobile 5.0 (I am purchaning a smartphone with windows mobile 5.0)?
Depends on which "smartphone" you have.Our keyboard supports both the HID and SPP Bluetooth profiles (services). Some of the newer WM5 models come with built-in HID service and will work as is with the keyboard.The other models will require the new VKB Driver for Windows Mobile 5 which is currently in work and scheduled to be released first week of February.

Your question wording is confusing, but I will attempt to guess what you mean and answer it.
Some (but not all) keyboards have a backlight to help you identify the keys in low lighting conditions.

That is the purpose of the key on the keyboard that you are asking about.

Why are the keys in a computer keyboard usually arranged in a haphazard manner?
The keys in a computer are arranged in a haphazard manner because,previously when computers were not there,typewriters were used for typing documents.Initially,the keys of a typewriter were arranged in alphabetical order.So the people would go on typing at ease, without any problem and so, the speed of typing was very fast.As a result,the sticks of the typewriter,which were connected to the keys would get tangled up thus resulting in the collapse of the machine.So, the keys were arranged in a haphazard manner to make it difficult for the user to type.This practice continued in the computers as well.
In short form, by means of a program, or part of a program, the way everything else happens in a computer.
Programmers and other engineers write code that looks at the keyboard for inputs from the operator. Various parts of various programs interpret the keyboard commands different ways, since you the operator may be hitting a key for different things, to exit the program, to start printing, to save the file, etc.
For your question, you have to assume that a text program like MS Word is operating. Word is waiting for you to enter information from the keyboard (it's in insert mode). As each key is hit, Word calculated what the key means and decides what key you hit, for example the "W" key.
Word looks up the letter in a table and finds the ASCII equivalent decimal number to the letter and stores this number in a memory buffer. As you hit the "o" "r" "d" keys MS Word looks each letter up and stores the decimal number in the buffer.
Now there are 4 numbers stored in sequential locations in a buffer.
Now let's suppose that you tell Word to save and exit.
The computer program will take all of the text that it has in various memory locations and writes it to disk, so at a later time you can load that digital info back into Word, display it on the screen and allow you to type in more words.
That was the somewhat less simple explanation. Can't get more complicated without writing a few textbooks.
AnswerEach key on the keyboard is assigned a number. Hold down your alt key while typing in a number from 1-255 in notepad.
that not tranlate to digital information
First it needs an encoder that converts information from what we call decimal form to binary, and then in order for the information to appear on the screen, you need a decoder that takes binary and converts it back to decimal.
What are common reasons that a key on a laptop or computer keyboard would stop working?
The most common reason for a key on a laptop or computer keyboard to stop working is dust or debris that is under the key. Turn off the PC or laptop. If desktop, unplug the keyboard from the PC. Lay out sheets of newspaper on the floor and sit on the floor with the laptop or PC keyboard. Gently turn it upside down (must open the laptop lid for this) and GENTLY tap very few inches across the bottom. Dust and debris should fall out onto the newspaper. Also tap along the edges on all sides.
Next, if you have a can of air used on computers, (make sure the area is well ventilated and), hold the keyboard at an angle and blow out remaining dust. Let dry completely.
Use a SMALL amount of rubbing alcohol on a soft paper towel to wipe off the tops of the keys. LET DRY.
Reattach to PC or power. Try the keys.
If it still will not work, you may need help to pop off the letter cap and use tweezers to lift out any debris. UNPLUG FIRST. And BE careful -- there are 3 pieces under a cap that MUST stay in place, 2 plastic frames and a rubber cap in the center. To reattach the key, align it in its slot and press on the corners so it pops back on.
