A study on selection ability in the 3D space by the finger

Abstract

Intuitive gestures are very effective for interactions. Pointing gesture with a finger would be used for interactions like pie menu selection. It has been researched as to the appropriate numbers of menu items being displayed in a pie menu. However, no research has been made for the case where menus are selected by using gestures. We will experiment in order to examine the ability of pointing gesture (selection ability) in the 3-dimensional space. The experiment was conducted in order to find out the test subjects' selection ability of pointing gesture. By combining the obtained resolution abilities of pointing gesture at the 2-dimentional surface of Pitch and Yaw, it is suggested that the selection ability of selection behavior in the 3-dimentional space is 22 areas. © 2011 Springer-Verlag.
