Spatial perspective taking is a crucial social skill that underlies many of our everyday interactions. Previous studies have suggested that spatial perspective taking is an embodied process that involves the integration of both motor and proprioceptive information. Given the importance of vestibular signals for own-body perception, mental own-body imagery, and bodily self-consciousness, in the present study we hypothesized that vestibular stimulation due to passive own-body displacements should also modulate spatial perspective taking. Participants performed an own-body transformation task while being passively rotated in a clockwise or counter-clockwise direction on a human motion platform. A congruency effect was observed, reflected in faster reaction times if the implied mental body rotation direction matched the actual rotation direction of the chair. These findings indicate that vestibular stimulation modulates and facilitates mental perspective taking, thereby highlighting the importance of integrating multisensory bodily information for spatial perspective taking.

Abstract. In order to make a step further towards understanding the impact of multi-modal stimuli in Virtual Reality we conducted a user study with 80 participants performing tasks in a virtual pit environment. Participants were divided into four groups, each presented a different combination of multi-sensory stimuli. Those included real-time 3D graphics, audio stimuli (ambient, static and event sounds), and haptics consisting of wind and tactile feedback when touching objects. A presence questionnaire was used to evaluate subjectively reported presence on the one hand, and on the other physiological sensors were used to measure heart rate and skin conductance as an objective measure. Results strongly indicate that an increase of modalities does not automatically result in an increase of presence.

“…Programmable graphic pipeline could be of help to refine clipped edge rendering though effects like fading or appropriate filling. An advanced evaluation has to be conducted, using a collection of static scenes in conjunction with subjective and quantitative evaluation methods for the eye strain parameter [10]. The influence of surrounds in the Black Bands method is another point to clarify.…”

Frame cancellation comes from the conflict between two depth cues: stereo disparity and occlusion with the screen border. When this conflict occurs, the user suffers from poor depth perception of the scene. It also leads to uncomfortable viewing and eyestrain due to problems in fusing left and right images.In this paper we propose a novel method to avoid frame cancellation in real-time stereoscopic rendering. To solve the disparity/frame occlusion conflict, we propose rendering only the part of the viewing volume that is free of conflict by using clipping methods available in standard real-time 3D APIs. This volume is called the "Stereo Compatible Volume" (SCV) and the method is named "Stereo Compatible Volume Clipping" (SCVC).Black Bands, a proven method initially designed for stereoscopic movies is also implemented to conduct an evaluation. Twenty two people were asked to answer open questions and to score criteria for SCVC, Black Bands and a Control method with no specific treatment. Results show that subjective preference and user's depth perception near screen edge seem improved by SCVC, and that Black Bands did not achieve the performance we expected.At a time when stereoscopic capable hardware is available from the mass consumer market, the disparity/frame occlusion conflict in stereoscopic rendering will become more noticeable. SCVC could be a solution to recommend. SCVC's simplicity of implementation makes the method able to target a wide range of rendering software from VR application to game engine.
