Personal space

Abstract

Reality-Based Interaction (RBI) [14] theorizes that realistic user interactions(UIs)are effective because they exploit users' pre-existing knowledge about their bodies and objects in the world. Gesture based interaction allows users to relay information to a computer through body movement without physical contact with additional hardware such as a mouse or trackball. However, this interaction style requires the users to interact in a manner that is tailored for the system to recognize with very strict rules for bodily interaction, not toward a gesture space that is more natural for the user. In this paper we propose a natural method of gestural input through a user-defined 3-dimensional space. We conducted two pilot studies to assess the performance and usability of these augmented gestural pointing methods for cursor manipulation as compared to a standard mouse interaction as well as the current standard approach used in gestural input.
