1. A non-transitory computer readable medium comprising computer readable code executable by one or more processors to:
receive image data of a touching object and a target surface, wherein the touching object is situated between a camera capturing the image data and the target surface;
determine, based on the image data, a velocity of the touching object;
in response to determining that the velocity of the touching object satisfies a predetermined threshold, modify a threshold hover distance between the touching object and a target surface at which a touch event is determined to have occurred;
detect one or more additional touch events between the touching object and the target surface using the modified threshold hover distance.
