Reactive Ocular and Balance Control in Immersive Visual Flows: 2D vs. 3D Virtual Stimuli
نویسندگان
چکیده
The control of gaze and balance strongly depend on the processing of visual cues. The aim of this study is to assess the effects of the dynamic 2D and 3D visual inputs on the oculomotor and balance reactive control. Thirteen subjects were immersed in a virtual environment using 10 different 2D/3D visual flow conditions. Analysis of eye movement and postural adjustments shows that 2D and 3D flows induce specific measurable behavioral responses.

An Immersive Virtual Environment for Visuo-Vestibular Therapy
The sense of equilibrium aggregates several interacting cues. On patients with vestibular loss, vision plays a major role. In this study, the goal is to propose a new immersive therapy based on 3D optokinetic stimulation. We propose to demonstrate that 3D monoscopic optical flows is an efficient tool to stimulate adaptive postural adjustment. We developed an immersive therapeutic platform that ...

Most research on three-dimensional (3D) visual-spatial processing has been conducted using traditional non-immersive 2D displays. Here we investigated how individuals generate and transform mental images within 3D immersive (3DI) virtual environments, in which the viewers perceive themselves as being surrounded by a 3D world. In Experiment 1, we compared participants' performance on the Shepard...

The sense of equilibrium aggregates several interacting cues. On vestibular areflexic patients, vision plays a major role. We developed an immersive therapeutic platform, based on 3D opto-kinetic stimulation that enables to tune the difficulty of the balance task by managing the type of optic flow and its speed. The balance adjustments are recorded by a force plate, quantified by the length of ...
متن کاملThe role of vertical disparities in the oblique effect
A great deal of studies using different visual tasks (e.g., Vernier acuity tasks, tilt illusion, crowding, etc) have revealed that our perception is strongly influenced by the orientation of the stimulus. Most studies have investigated visual acuity in twodimensional visual spaces (2D) but little is known about the effect of line orientation in depth perception (3D). In one experiment, Vernier ...
