The embodiment of the invention provides a displacement acquisition method and device of an air mouse. The method comprises: collecting gravitational acceleration, which currently corresponds to the air mouse, of three-axis directions; determining first attitude angles, which currently correspond to the air mouse, according to the gravitational acceleration; correcting the first attitude angles; determining a current moving speed of the air mouse according to a comparison result of the corrected first attitude angles and second attitude angles corresponding to original coordinates; and determining current coordinates, which correspond to the air mouse, according to the current moving speed of the air mouse and the original coordinates corresponding to the air mouse before moving according to the moving speed. Through correcting the first attitude angles, difference degree comparison is carried out on the corrected first attitude angles and the second attitude angles, which correspond to a coordinate position where the air mouse is last located, to overcome adverse impacts of noise, air mouse over-sensitivity and the like on air mouse coordinate position determination.
Description
technical field [0001] The invention relates to the technical field of air mice, in particular to a method and device for acquiring displacement of air mice. Background technique [0002] Air mouse is a kind of wireless mouse, which has the characteristics of small size, easy to carry, comfortable operation, and not limited by space. , referred to as AR) and other somatosensory interaction fields have attracted much attention. For example, in game applications, the realization of the air mouse function (also known as somatosensory air mouse) in some somatosensory devices can enable gamers to get rid of the traditional mechanical mouse for game operations and enjoy a better experience. [0003] In practical applications, we often encounter such a situation: the user does not actually want the air mouse to move, but for some reason the air mouse moves slightly, and the high sensitivity of the air mouse may cause the display to The coordinate position of the air mouse display...
