Abstract:
1. A method for reducing power consumption in an electronic device by controlling the transition of the electronic device from a sleep mode to a full power mode, the electronic device comprising a main processor, a touch-sensitive overlay, and an overlay controller, the method comprising: detecting and capturing a sequence of touch inputs on the touch-sensitive overlay using the overlay controller while the main processor is in the sleep mode; processing a subset of the sequence of touch inputs using the overlay controller to determine that the sequence of touch inputs corresponds to a coarse model of a pre-determined wake-up gesture, the pre-determined wake-up gesture being adapted to transition the electronic device from the sleep mode to the full-power mode; transitioning the main processor from the sleep mode to the full power mode; processing the entire sequence of touch inputs using the main processor to determine that the sequence of touch inputs corresponds to a fine model of the pre-determined wake-up gesture to transition the electronic device from the sleep mode to the full power mode; and, transitioning the electronic device from the sleep mode to the full power mode.
