In this paper we present an initial investigation of foot tapping as a mechanism for interacting with a mobile device without removing it from a pocket. We compare a foot tapping technique for menu interaction with two more traditional situations: one where the user has the phone in hand, and one where the user must remove it from an inside pocket before interacting. Results show that over the course of the full study, all conditions allowed a high level of accuracy in selections. The visual and in pocket conditions were overall faster and more accurate. However, for short selections requiring four or less foot taps or button presses the foot tap condition was faster than the in pocket condition.
