Detecting vibrations generated by a swipe gesture
In some examples, a computing device may include a swipeable portion with a material having a textured surface. A primary sensor may receive motion-generated data when a swipe gesture is performed on the swipeable portion and send primary data to an embedded controller (EC). The primary sensor may be mounted between two layers of vibration damping material. The EC may filter the primary data to create filtered data. The EC may determine that the filtered data satisfies one or more criteria to determine that the swipe gesture was performed. In response, the EC may perform one or more associated actions, such as determining and displaying a battery level of a battery of the computing device.
