It’s a geeky input device whereby the image of a virtual keyboard is projected onto a surface and your keystrokes are translated to your computer when you place fingers on the projected “keys”.
This is like carrying a small optical virtual keyboard in your bag except that the keyboard is physically non-existent. It can emulate unlimited types of manually operated input devices (such as a mouse, keyboard, and others that your devices may support). This compact device can be connected to your phone or computer via Bluetooth 2.0, and will work on any flat, reflective surface. The keyboard has a comfortable 19 mm key pitch, and it can optically detect up to 350 keystrokes per minute. The brightness of the laser keyboard and the detection sensitivity can be adjusted in three levels for the user’s physiology maintaining speed, simplicity and unambiguity of manual data input. Expected to be available April 10, for about $350.
