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.

Compatibility with the Virtual Keyboard (VKB)

Along with laptops and desktops, the infrared keyboard can be a mobile phone keyboard or PDA keyboard. Listed below are the devises and the corresponding operating systems with which it works.

I got my unit and i cannot connect it?

1. Perform a "hard" reset. While keyboard is on insert end of paper-clip into reset hole under rubber flap on lower right side; Wait for beep; Pick up keyboard, wait for it to turn off; place on surface and turn on. Keyboard now ready for pairing. 2. Ensure that Serial Port service is enabled on your PocketPC - BT Settings->Services->Serial Port (Make sure is enabled, encrypted and Incoming and Outgoing COM ports enabled). 3. Perform pairing (BT Manager ->Tools->Paired Devices) 4. Open SPP connection via BT Manager->New->Explore a Bluetooth Device->(Select VKB Keyboard)->SPP->Finish 5. My ShortCuts->(Long Press on SPP)->Connect

Has keyboard connected ? (VKB Keyboard LED is solid blue) ?

If the process above has failed. Please tell us at which stage it failed. Was a message displayed?

Please fill the contact us form with all the error details, and mention a "Hardware failure".

Thanks.

I got my unit and i cannot connect it to Dell Axim x50?

1. First pair with the BT VKB as described in the user manual.

2. Go to the Bluetooth Manager and select "Explore a Bluetooth Device".

3. Turn on the BT VKB and the PDA should discover a service called SSP (a serial port).

4. Enter a pass code (I used "0000") on the BT VKB and "press" (hit) the enter key on the BT VKB.

5. The PDA should respond by bring up a screen for you to enter the same pass code.

6. Create a short cut in your Bluetooth manager.

7. When you want to connect, click & hold the short cut you created in step 7, click "Connect". The short cut should turn green to indicate you're connected.

8. Launch the BT VKB program; make certain that Bluetooth is selected under the Connection tab.

9. Select the VKB tab, select the "Enable Keyboard, answer No to the question "Is this the first time you are connecting to the keyboard."

You should now see the battery level and be connected.

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.

What is the difference between the qwerty keyboard and the concept keyboard?

A concept keyboard is a flat board which contains a grid of switches. Each switch can be programmed to do whatever you want. An overlay image is placed on top of the grid so that the user can tell what pressing on different areas (switches) will do. Example uses of concept keyboards include :Games for young children : The overlay image could be a picture of a farmyard. Pressing on an animal would cause the computer to make the noise the animal does.Tills in restaurants/pubs : The overlay contains a list of all the meals that can be sold. Instead of typing in prices the waiter simply presses the keyboard where the meals/drinks he is serving are listed.Concept keyboards are particularly useful for people who would find using an ordinary keyboard difficult and in locations where an ordinary keyboard might be damaged, e.g. by spillage or dust.

Does Analogue computers have a higher accuracy in their operation?

This is a brief description of an analogue computerAn analog computer is a form of computer that uses the continuously changeable aspects of physical phenomena such as electrical,mechanical, or hydraulic quantities to model the problem being solved. In contrast, digital computers represent varying quantities symbolically, as their numerical values change. As an analog computer does not use discrete values, but rather continuous values, processes cannot be reliably repeated with exact equivalence, as they can with Turing machines. Analog computers do not suffer from the quantization noise inherent in digital computers, but are limited instead by analog noise.Analog computers were widely used in scientific and industrial applications where digital computers of the time lacked sufficient performance. Analog computers can have a very wide range of complexity. Slide rules and nomographs are the simplest, while naval gunfire control computers and large hybrid digital/analog computers were among the most complicated.[1] Systems for process control and protective relaysused analog computation to perform control and protective functions.Source: Wikipedia
