Touch pad controller

A system for providing non-linear control over electrical appliances, comprising:

• (a) a touch plate having an inner surface and an outer surface, which is accessible to a user;
• (b) a piezoelectric sensor array coupled with said inner surface of said touch plate and suitable to generate electric signals when deformed by pressure;
• (c) a microcontroller connected to said piezoelectric module, said microcontroller being configured to analyze electrical signals generated by said piezoelectric module, to determine control signals therefrom;
• (d) circuitry coupled with said microcontroller, for receiving said control signals and for transmitting output signals to said electrical appliance;
• and
• (e) a feedback module connected to said microcontroller, suitable to provide to a user feedback related to signals generated by said piezoelectric module.
