1. A method for reducing power consumption of an input device having an auxiliary sensor and a main sensor, the method comprising:
- calibrating the auxiliary sensor in accordance with a comparison between an input of the auxiliary sensor and an input of the main sensor;
entering, by a processor, the input device into a sleep mode in which the auxiliary sensor is in an active mode and the main sensor is in the sleep mode;
detecting, by the auxiliary sensor, a user input received by the input device from a user;
waking, by the processor, the main sensor; and
placing the main sensor in the sleep mode in response to the auxiliary sensor and the main sensor detecting no user input over a predetermined time period.

Abstract
An input device for an electronic device. The input device includes a power source, a processor in communication with the power source. Additionally, the input device includes a main sensor in communication with processor and configured to detect a user input and an auxiliary sensor in communication with the processor and configured to detect a user input. When the input device is in a normal power mode or active state, the main sensor is activated and when the input device is in a low power state the main sensor is deactivate and the auxiliary sensor is activated.
