Abstract:Recent developments in the field of interface design, as the development of 3D displays and their implementations, heightened the important role of research in user interface design. It is unclear if such technical systems are of advantage to attentional processing in 3D space. Humans’ perceptual experiences of the external world are limited, abstract, incomplete and often implicit (Rensink, 2000; Mazza et al., 2005). Therefore, it often happens that a person fails to detect changes when he/she is viewing a visual scene. This robust change blindness phenomenon, which is the failure to detect changes in scenes can result from visual disruptions within the field of view. A considerable amount of literature has been published on focused attention with change blindness / detections tasks in 2.5D displays but not in stereoscopic 3D displays (see Mazza, Turatto & Umilta, 2005). Goal of the present study was to establish whether the benefit of providing spatial cues for change detection using 2D / 2.5D displays generalizes to 3D displays. To do so, the experimental design was based on a study conducted by Becker, Pashler and Anstis (2000).Numerous studies have shown that change detection performance can be increased with the presentation of a cue which enhances attentional processing at the cued (attended) location (Posner, Snyder & Davidson, 1980). Theeuwes, Atchley and Kramer (1998) investigated cueing of attention in 3D space through binocular disparity. Their results indicate that focused attention, which is necessary for change detection, can be allocated in 3D space.
