PSoC Mini
The PSoC Mini is an open-source hardware, 8051 pin-compatible version of Cypress Semiconductor's PSoC 3 System-on-a-chip microcontroller. The PSoC is a powerful microcontroller due to it's flexible digital block array and powerful analog routing features.
The PSoC Mini includes an on-board USB programmer, 36 pins that can be used for both digital and analog signals, an onboard regulator, and can take voltage from USB or from an external circuit. The project was funded by a grant from Cypress Semiconductor in collaboration with the Interface Ecology Lab. Future work will develop more open-source hardware PSoC development tools, including an Arduino compatible form-factor.

Scanning FTIR
Scanning FTIR is an optoelectronic multi-touch sensing technology that enables flat-panel, pressure sensitive multitouch sensing on nearly any display. By optically coupling a large number of IR emitters and IR sensors to a planar waveguide, the transmittance through the waveguide can be measured. Similar to CT scanning technologies, the final pressure image is an integral of measurements from all sensors and LEDs across each pixel.

Put your two hands on your desk
Now we are familiar with the idea of using our fingers (not a finger) to control cute gadgets. If using several fingers is that convenient, why don't you use two hands? Of course, this question is pursued by R. Clayton who proposed 10/GUI.
