1. A method for estimating locomotion in virtual reality performed by at least one processor, the method comprising:
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,
wherein the estimating of at least a portion of the locomotion direction and the locomotion speed of the user includes estimating the locomotion speed of the user when a pressure point corresponding to a maximum pressure value moves from one cluster to an other cluster using the plurality of footprint images.
