The plenhaptic guidance function for intuitive navigation in extended range telepresence scenarios

Abstract

In this work, we propose a plenhaptic guidance function that systematically describes the haptic information for guiding the user in the target environment. The plenhaptic guidance function defines the strength of the guidance at any position in space, at any direction, and at any time, and takes the geometry of the target environment as well as all possible goals into account. The plenhaptic guidance function, which can be rendered as active and passive guidance, is sampled and displayed to the user through a haptic interface in the user environment. The benefits of the plenhaptic guidance function for guiding the user to several simultaneous goals while avoiding the obstacles in a large target environment are demonstrated in real experiments.

Virtually Sensuous (Geographies): Towards a Strategy for Archiving Multi-user Experiential and Participatory Installations

“…I believe that recent developments in VR technologies can take us some way towards my goal, as VR now has the capacity to achieve for the viewer the physical experience of being fully present in a virtual world through: a) the advent of affordable, sophisticated audiovisual Head Mounted Displays (HMDs); b) advances in audiovisual rendering in, and the interactive capabilities of, Games Engines; c) the increasing attention being paid by VR developers to the interplay between the perceptual senses and the role this plays in our experience of the environment (Ajdler, 2006;Arias et al, 2011;Larsson et al, 2001;Wong et al, 2002).…”

“…Significantly the affective tone and spatial awareness of a VR environment are contingent on information derived from not only visual but also aural channelsto such an extent that a mismatch between the sonic and visual perceptual clues in a virtual world measurably reduce the sense of presence experienced by its visitors (Larsson et al, 2001;Arias et al, 2011;Ajdler et al 2006). Hence, in VR a rendering is needed of an emergent, spatially distributed multi-layered sonic environment which simulates the spatio-temporal acoustic field that flows from the volume and shaping of the environment.…”
