Summary: Personal Space in Virtual Reality

Improving the sense of "presence" is a common goal of three-dimensional (3D) display technology for film, television, and virtual
reality. However, there are instances in which 3D presentations may elicit unanticipated negative responses. For example, it is
well established that violations of interpersonal space cause discomfort in real-world situations. Here we ask if people respond
similarly when viewing life-sized stereoscopic images. Observers rated their level of comfort in response to animate and inanimate
objects in live and virtual (stereoscopic projection) viewing conditions. Electrodermal activity was also recorded to monitor their
physiological response to these stimuli. Observers exhibited significant negative reactions to violations of interpersonal space in
stereoscopic 3D displays, which were equivalent to those experienced in the natural environment. These data have important
implications for the creation of 3D media and the use of virtual reality systems.

1. INTRODUCTION
Stereoscopic 3D display technology has been employed in a wide variety of applications including IMAX
theatres, immersive virtual reality systems, such as the CAVE, endoscopic surgery [Yao et al. 2002] and
therapeutic intervention [Garcia-Palacios et al. 2002] To ensure that such technologies are exploited
fully by the intended users, it stands to reason that the technology be easy to use and create little or no
