A method and system for processing signals for a MEMS detector that enables control of a device using expulsion of air via human breath, a machine and/or a device are provided. A microprocessor may receive one or more signals from the MEMS detector that may comprise various component sensor(s), sensing member(s) or sensing segment(s) that may detect movement of air caused by the expulsion of human breath. The signals may be processed by the microprocessor and an interactive output comprising one or more control signals that may enable control of a user interface such as 107a-107e on the multimedia device 106a-106e may be generated. For each component sensor(s), sensing member(s) or sensing segment(s) in the MEMS detector, ranges or gradients may be measured and evaluated to determine which of the sensor(s), sensing member(s) or sensing segment(s) of the MEMS detector 212 may have been activated, moved or deflected.
