PC-Keyboard with force feedback: Sensorless position detection by current measurement

Grégory Savioz is working in collaboration with Logitech. The goal of his work is to develop a "haptique" keyboard. A functional prototype of one key was already realized. Till now a hall sensor was used to measure the position of the key. The prototype consists of a permanent magnet in an iron housing and a moving coil.
