Motion gestures enable natural and intuitive input in video games. However, game gestures designed by developers may not always be the optimal gestures for players. A key challenge in designing appropriate game gestures lies in the interaction-intensive nature of video games, i.e., several actions/commands may need to be executed concurrently using different body parts. This study analyzes user preferences in game gestures, with the aim of accommodating high interactivity during gameplay. Two user-elicitation studies were conducted: first, to determine user preferences, participants were asked to define gestures for common game actions/commands; second, to develop effective combined-gestures, participants were asked to define possible game gestures using each body part (one and two hands, one and two legs, head, eyes, and torso). Our study presents a set of suitable and alternative body parts for common game actions/commands. We also present some simultaneously applied game gestures that assist interaction in highly interactive game situations (e.g., selecting a weapon with the feet while shooting with the hand). Interesting design implications are further discussed, e.g., transferability between hand and leg gestures.
