André Guignard : ウィキペディア英語版 | André Guignard
André Guignard is a Swiss engineer initially educated as a watchmaker. He is the creator of the mechanic of the Khepera, the S-bot and several other mobile robots. Working at the LAMI of the EPFL with Professor Jean-Daniel Nicoud, he designed and realised in 1977 the first modern computer mouse, that started the successful Logitech diversification. Born in 1942, he was enrolled at the EPFL in 1976 and made many research projects successful due to an exceptional mastering of how to conceive and build micromechanical systems. His interaction with students was always greatly appreciated. He retired in March 2007, but still helps part time with EPFL research projects. ==The Swiss Mouse==
Prototypes of an improved Engelbart mouse with an optical encoder were built at LAMI-EPFL in 1972 ((see EPFL mouse story )), but there was no need for a mouse when graphic screens were not available. The LAMI-EPFL developed several microprocessor driven graphic screens since 1974 and André Guignard designed in 1977 a reliable mechanism for measuring the ball movement with optical encoders. This was the first modern computer mouse using an optical encoder.
