a study of hand shape use in tabletop gesture interaction
Although manual gesture has long been suggested as an intuitive method of input for horizontal human-computer systems, little research has been conducted into observing user preferences for tabletop gesture interaction. This is particularly the case for computer vision-based gesture input, where the recognition of different hand shapes opens up a new vocabulary of interaction. In this paper, results from an observational study of manual gesture input for a tabletop display are discussed. Implications for tabletop gesture interaction design include suggestions for the use of different hands shapes for input, the desirability of combined touch screen and computer vision gesture input, and possibilities for flexible two-handed interaction.
