Gesture Elicitation Study on How to Opt-in & Opt-out from Interactions with Public Displays

Explore a gesture elicitation study examining how people can opt-in and opt-out of interactions with public displays using gestures or voice commands. Delve into the research conducted at the ACM International Conference on Interactive Surfaces and Spaces, which involved 16 participants generating gestures for commercial and entertainment scenarios. Analyze the categorization of 430 proposed gestures, agreement scores, and patterns in non-verbal representations. Examine quantitative results showing preferences for hand and arm gestures, and higher acceptance for gestural interaction in entertainment settings. Discuss the implications for designing more user-friendly public interactive displays with gesture-recognizing cameras, addressing issues of voluntary engagement and disengagement.
