However, research on input for games on smart glasses has been constrained by the available sensors to date. To help in- form design directions, this paper explores user-defined game input for smart glasses beyond the capabilities of current sensors, and focuses on the inter- action in public settings. We conducted a user-defined input study with 24 participants, each performing 17 common game control tasks using 3 classes of interaction and 2 form factors of smart glasses, for a total of 2448 trials. Re- sults show that users significantly preferred non-touch and non-handheld in- teraction over using handheld input devices, such as in-air gestures. Also, for touch input without handheld devices, users preferred interacting with their palms over wearable devices (51% vs 20%). In addition, users preferred in- teractions that are less noticeable due to concerns with social acceptance, and preferred in-air gestures in front of the torso rather than in front of the face (63% vs 37%).
