The Virtual Laser Keyboard

Tell me what it is??

This is exactly what you would want to take out of your inner coat pocket and use during a presentation, or want it as a business gift. The device is wrapped in an elegant leather jacket and compatible with almost all smatphones, Blackberry, PDA, MAC, Nokia (Symbian series) and Tablet PC’s. VKB (Virtual Laser Keyboard) is a ground breaking accessory. It is light and merely a size of a zipo lighter. It generates a full size fully operating laser keyboard.


VKB’s operations are exactly like those of a conventional keyboard. The user has to tap the projected imaged keys, based on optical recognition mechanism (directional technology). An extra affect added to it is the real tapping sound it makes when the keys are tapped.


The dimensions of VKB are (90 x 34 x 24 mm). It is a normal keyboard with the help of which users can type texts or emails easily, except for the fact that it fits in a pocket. You can leave behind your lap tops back home. Because it is a laser projected keyboard, it does not have any mechanical moving parts.

It is a laser projected full sized keyboard which disappears completely when turned off. It studies the finger movement of the user, construe it and record the key strokes. When it comes to damage and maintenance, it is free of these worries. It gives the user the leverage to change the setting through either your PC, your smartphone or compatible PDA.

Some of the settings that can be changed are:

  • Sounds: key clicks of the virtual key board can be controlled.
  • Connections to the compatible computer / smartphone / PDA e.t.c.
  • To save the battery of VKB it can be switched off after decided intervals.
  • Sensitivity of the keyboard is also adjustable.


It can be used at and with:

  • Laptops , it is even compatible with MAC
  • PDA’s (Personal Digital Assistants
  • Celluar telephones
  • Industrial environments
  • Testing equipments
  • Medical environments where extra equipment is not allowed.
  • While traveling


This technology has four basic parts, their description and the way of working is described below.

  • Projection Module:

It is used to illuminate the preferred interface on the surface. In this case it is a key board. A highly efficient holographic element with a red diode laser is used to project the template. This projected template is only a reference for the user to know where to strike, it is not used for the detection of key strikes.

  • Micro-Illumination Module TM:

This module generates a plane of infra-red light just millimeters above the project template by the projection module. When a key is touched by the user on the projected keyboard, the infra-red light is reflected back towards the sensor module.

  • Sensor Module:

A sensor chip called “Virtual Interface Processing Core” calculates the real location of strike after the reflected infra-red light passes through the infra-red filter and falls on CMOS image sensor. It also has the capability of following multiple reflections concurrently, so it supports and detects multiple key strikes.

  • Micro Controller:

The eventual information transfer to the output device is done through here. A micro controller is present in the sensor module which receives information from the sensor processing core in the form of light flashes. These flashes are then deduced into real information for example, Tab key, return key or mouse etc.

  • […] that’s better than the keyboards offered yet, whether they are on iphone or a pocket keyboard (We wrote about the Laser keyboard that can fit in to your pocket, you might want to have a look). The tablet could be relying on Articulating Frame, so the surface of the tablet would generate […]

  • Just got this yesterday. Nice and light, built very sturdy . The screen is bright and sharp. Mouse pad pretty response and the keyboard feels good. The 6 cell battery will last over 6 hours with WIFI in use. I can’t see anything wrong with this system. I would hv preferred to have the bluetooth and the SIM card slot, but those can be added through third party products. I was also interested in the ASUS, but did not like the keyboard and also heard that customer service was not so good.

    Highly impressed, found your blog on Yahoo!.Glad I finally tested it out. Not sure if its my Chrome browser,but sometimes when I visit your site, the fonts are really small? Anyway, love your webpage and will check back.See Ya

    This is too good,but why you dont display how you made it,i am a engineering student and i want to know the basics that how it is made?????

  • ~`’ I am very thankful to this topic because it really gives up to date information `,,

  • Im happy I found this blog, I couldnt obtain any information on this subject prior to. I also run a website and if you are ever interested in doing a bit of guest writing for me please feel free to let me know, i’m always look for people to check out my blog site. Please stop by and leave a comment sometime!

    We’ll be fair: nobody like when things like this happen to them. So, I have to explain this fairly upstanding affair

    I positively like your post. I suppose it’s definitely heartening you made your mind to write on this matter. It will definitely enlighten others to read what you think about. Thanks
