A user can provide input to an electronic device by performing a specific motion or gesture that can be detected by the device. At least one imaging or detection element captures information including the motion or gesture, such that one or more dwell points can be determined in two or three dimensions of space. The dwell points can correspond to any point where the motion pauses for at least a minimum amount of time, such as at an endpoint or a point where the motion significantly changes or reverses direction. The set of dwell points, and the order in which those dwell points occur, can be compared against a set of gestures to attempt to match a gesture associated with a particular input. Such an approach is useful for devices with image capture elements or other components that are not able to accurately capture motion or determine movements, etc.
