We have yet to purchase the Virtual Laser Keyboard, but we have been waiting for this technology to become available.  It projects the image of a keyboard onto a flat surface, and uses lasers to sense key-press events. Currently, it is about the size of a cellular phone, and comes with either bluetooth or serial connectivity.

This technology, when coupled with various types of electronic ink and oled displays that are also being developed, could be used in the future to produce a very small keyboard and video hookup for a small computing device. Currently, that device is a PDA or mobile phone, both of which are continuing to increase their computer power.

For now, however, we believe as soon as the price point reduces, it may become a viable option for the basic of mobile functions, word processing, if nothing else.
