Abstract :
As a preliminary research into extending the concept of direct touch to indirect spatial gesture, we conducted a user study to determine the relationship between gestural motor space and display space. From the results of a user study, we define a user-driven mapping between an area on motor space and a point on visual space. For 16 points in display space, we find the motor space radius interval of a standard deviation from mean and angle interval that statistically cover 96% of trials. We introduce a new concept of absolute free-hand pointing technique that connects a certain area in motor space to a visual object in display space without aid of a cursor.
