The purpose of this study is to analyze the types of commands are appropriate to gesticulate when controlling a smart TV. Previous studies on gesture interface could be classified into three approaches; (1) contextual approach: how to suggest appropriate gesture based on the use case, (2) technological approach: how to implement gesture interface effectively and efficiently, (3) relationship approach: how to find the contextual association between command and gesture. However few studies exist emphasize the ‘gesture-ability’ of commands. The experiment was conducted to understand the relationship between ‘gesture-appropriate score’ and ‘command variables’. For the experiment, eighty seven commands of smart TV were collected and three command variables (‘frequency’, ‘depth’, ‘type’) were selected. Also, levels of each command variable were classified. Gesture-appropriate scores were significantly different between the levels of each command variable. The optimal levels of each command variable were suggested by conducting multiple linear regressions. From the results, we found that high frequency level, low depth level, navigation/move type commands were preferred as a gesture interface. With the results of this study, the designers of gesture interface are able to consider the important command variables for designing gesture interface.
