Abstract

In this paper 'presence' (a sense of 'being there' in a mediated environment) is proposed as a global quality metric with which to evaluate advanced multi-modal media systems. The development of a new presence selfreport measure, the ITC-Sense of Presence Inventory (ITC-SOPI), is described that comprises four empirically derived scales: Sense of Physical Space, Engagement, Ecological Validity, and Negative Effects. Two applications of the ITC-SOPI are presented. Using both controlled and uncontrolled experimental designs, the sensitivity of the ITC-SOPI scales to degree of physical immersivity (e.g., large vs. small format; monoscopic vs. stereoscopic viewing condition) is demonstrated. These preliminary results suggest that the ITC-SOPI is a valid tool with which to evaluate experiential aspects of immersive technology.
