Schedule in February 2015
The 20th Perceptual Frontier Seminar: Self-motion
Date and time: Monday, 2 February 2015, from 17:00 to 19:00
1. Opening remarks and an introduction to self-motion perception
Recent studies on self-motion perception, i.e., vection, are overviewed. Vection strength can be modulated by many factors. For example, individual differences of a sense of immersion can alter vection strength. In this talk, this aspect of vection will be explained.
2. Effects of surface qualities of objects on self-motion perception
Every object we encounter in our daily lives is made of materials that have specific light-reflecting properties and textures, i.e., surface qualities. Recently, increasing attention has been given to understanding how we perceive surface qualities of materials. Since the illusory self-motion occurs with optic flow in an environment, there is a possibility that surface qualities of moving objects in an environment influence induction and strength of self-motion perception. In this talk, we will introduce our recent study that tried to examine the effect of surface qualities on perception of self-motion.
3. Some visual variables that affect motion sickness and self-motion perception
Motion sickness is accompanied by self-motion that is actual and/or perceived. What is ‘seen’ often affects both the severity of MS symptoms and motion perception salience. In general, we propose that as the visual perceptual framework is strengthened, discordances between visual inputs to the brain and other senses (e.g. vestibular) will be accentuated—leading to more sensory conflict and more severe MS symptoms. When self-motion perception is illusory, as is the case when vection occurs, a stronger perceptual framework will facilitate self-motion perception. Some variables addressed will include articulation of the visual field, color, and monocular vs. binocular viewing.
We will dine out after the seminar. If you would like to join, please send Dr. Seno an e-mail (seno [@] design.kyushu-u.ac.jp).
