Abstract
Methods and apparatus related classifying touch events are disclosed. A first event is detected at a touch interface of a wearable computing device. Detecting the first event includes detecting a first capacitance change at the touch interface. A first-event signature of the first event is determined based on at least the first capacitance change. A first-event classification for the first event is selected from among a touch classification and a potential-touch classification based on the first-event signature. A first-event confidence value for the first-event classification is determined. Contextual information during a predetermined time after detecting the first event is obtained. The first-event classification can be adjusted based on the contextual information.
