In this paper, we investigate wrist rotation as a hands-free method of interaction with a mobile device. To evaluate this technique, a Fitts' Law targeting study is described in four different postures: resting, seated, standing and walking. Results show correlations in movement time and the Index of Difficulty of the task and similarities in the targeting performance for the first three conditions, but show walking and targeting using this method was significantly more difficult.
