Enhancing Interactivity in Handheld AR Environments

Abstract

In this paper we present a trial of development of handheld AR support- ing two interaction techniques based on the understanding that both real and virtual objects should be compatible in manipulation. One is the ability to contact virtual objects by user’s finger, as well as to physical objects in the real world. The virtual objects change their position, shape, and/or other graphical features according to his/her manipulation. The other technique we discuss in the paper concerns pseudo manipulation of virtual objects. The motion such as shake and tilt to a handheld device causes a certain effect to the virtual objects in the AR content. 1
