Gesture interface appropriateness analysis on smart TV functions

The aim of this study is to examine the types of commands are appropriate to gesticulate when controlling a smart TV. The experiment was conducted to see the relationship between `gesture-appropriate score' and `function variables'. For the experiment, eighty-seven commands of smart TV were extracted and three function variables (`frequency', `depth', `type') were selected. Also, the levels of each function variable were classified. Gesture-appropriate scores were significantly different between the levels of each function variable. The optimal levels of each function variable were suggested by conducting conjoint analysis. From the results, we found that high frequency level, low depth level, navigation/move type functions were preferred as a gesture interface. With the results of this research, the gesture interface designers are able to consider the priority of function variables for designing gesture interface.
