THERMOSTAT GESTURE CONTROL

摘要

A method and apparatus to enable the control of a building HVAC thermostat using hand gestures is provided so that there is no need to physically touch the thermostat to change its state. A thermostat controller for building HVAC systems that is responsive to hand gestures may include: at least one sensor responsive to hand gestures; a recognition circuit coupled to receive signals from the at least one sensor and adapted to determine gesture parameters therefrom; a processor coupled to the recognition circuit and adapted to determine HVAC control parameters from the gesture parameters; and HVAC control circuitry for controlling HVAC systems in accordance with HVAC control parameters communicated from the processor circuit. The at least one sensor may be supported by a housing, wherein the at least one sensor is responsive to hand gestures only in proximity to the housing. The thermostat controller can include a thermostat display screen mounted in the housing, with a plurality of sensor electrodes arranged in a two-dimensional pattern in front of and/or around the periphery of the display screen.
