Designing Mid-Air TV Gestures for Blind People Using User and Choice-Based Elicitation Approaches Nem Khan Dim Silpasuwanchai, Chaklam Sarcar, Sayan Ren, Xiangshi Mid-air gestures enable intuitive and natural interactions. However, few studies have investigated the use of mid-air gestures for blind people. TV interactions are one promising use of mid-air gestures for blind people, as “listening” to TV is one of their most common activities. Thus, we investigated mid-air TV gestures for blind people through two studies. Study 1 used a user-elicitation approach where blind people were asked to define gestures given a set of commands. Then, we present a classification of gesture types and the frequency of body parts usage. Nevertheless, our participants had di_culty imagining gestures for some commands. Thus, we conducted Study 2 that used a choice-based elicitation approach where the participants selected their favorite gesture from a predefined list of choices. We found that providing choices help guide users to discover suitable gestures for unfamiliar commands. We discuss concrete design guidelines for mid-air TV gestures for blind people. 2016 http://hdl.handle.net/20.500.12678/0000001934 https://meral.edu.mm/records/1934
