Abstract:
Described herein are techniques related to capacitance-based keyswitch technologies. According to one implementation, an apparatus includes a key with a floating electrode. The floating electrode pairs with a fixed electrode and a capacitance may be generated between them. The apparatus has a controller configured to measure the capacitance as the electrodes move relative to each other as the key is depressed and released. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
