Conventional human-machine interaction that relies on vision and audition requires state of-the-art technology that uses tens of watts, making it impossible to run the necessary algorithms continuously under battery power. It would be desirable economically and ecologically to burn full power only when the presence of a human desiring interaction is detected. This project takes its inspiration from nature, where interactions among species require high effort (and high energy consumption) only for limited periods of time of their engagement and at all other times, the organisms are alert for general classes of stimuli but the efforts are low and their energy is conserved.
We will try to mimick this behaviour by developing integrated micropower face and voice detection technology that in conjunction can provide a reliable and power-efficient wake-up cue for higher-level processing.
