Use of a 3DOF accelerometer for foot tracking and gesture recognition in mobile HCI

Touch screens as a mean for interacting with mobile applications are limited. Since the hands are already busy handling the phone or tablet, this paper proposes an innovative solution in handling digital entities with the feet. A three-axis accelerometer is arranged on a shoe in order to recognize its movement and to determine its position. Extraction of both information improves mobile interaction in different situations, especially in gaming and working in limited space. The contribution of this paper is an algorithm designed in order to extract both feet tracking (pose) and movement recognition such as kicking, sliding and rotating
