Abstract:
1. A method comprising: sending a first transmitted signal that has a first transmitted frequency from a signal transmitter, wherein the signal transmitter is positioned on a wearable computing device such that, when the wearable computing device is worn, the signal transmitter couples to a part of a wearer of the wearable computing device; receiving input signals at a self-capacitance touchpad located on the wearable computing device, the received input signals being indicative of manual input on the self-capacitance touchpad; determining that a first received input signal of the received input signals has a first received frequency that is different from the first transmitted frequency; based on determining that the first received input signal has the first received frequency that is different from the first transmitted frequency, refraining from operating the wearable computing device in accordance with the manual input indicated by the first received input signal; determining that a second received input signal of the received input signals has a second received frequency that matches the first transmitted frequency; and based on the determining that the second received input signal has the second received frequency that matches the first transmitted frequency, operating the wearable computing device in accordance with the manual input indicated by the second received input signal.
