Abstract: A method for estimating locomotion in virtual reality performed by at least one processor includes measuring a plurality of pressure points according to a user's locomotion using a high-resolution tactile sensor including a plurality of pressure sensors, extracting a plurality of footprint images including the plurality of measured pressure points, clustering the plurality of pressure points into a first set of pressure points corresponding to a left foot and a second set of pressure points corresponding to a right foot, based on the plurality of extracted footprint images, and estimating at least a portion of a locomotion direction and a locomotion speed of the user using a first cluster corresponding to the first set of pressure points and a second cluster corresponding to the second set of pressure points.
