The future is truly now with CTX Virtual Technologies' VK200 KEYFOB -- a virtual laser keyboard. The device projects a working keyboard onto any surface and connects to devices via Bluetooth, making it possible to use the device with cellphones, tablets, computers and laptops.
The portable keyboard is just barely bigger than a standard house key, and has an attachment that allows it to be held on a keychain.
For those who enjoy the "clicking" sound of laptops, the VK200 simulates keyboard sounds as you type. It also has a battery that is easily rechargeable.
With holographic technology becoming increasingly interactive, as can be seen with this responsive laser keyboard, it will be interesting to see what more developments in this field will bring us.
