[Pattern of Body Sway While Viewing 3D Video Clips in Various Age Groups].

Objectives: These days, developments in graphical technology have resulted in an increase in the chance to view 3D video clips. Visually induced motion sickness (VIMS) has been widely reported as a negative result of viewing these clips. The onset of VIMS is explained by some hypotheses.

[Development of Visually Induced Motion Sickness Evaluation Index Using Gaze Data of Elderly People].

Objectives: The benefit of using a noncontact eye-tracking system is its low a burden on individuals for measuring biological signals. The goal of this study was to develop a visually induced motion sickness (VIMS) evaluation index using data collected with a noncontact eye-tracking system for driving simulator (DS) experiments.

Methods: The participants included nine elderly people with visual and balance functions that did not interfere with their daily life.

[Analysis of Characteristics of Eye Movement While Viewing Movies and Its Application].

In this article, we present the following: a background of visually induced motion sickness (VIMS), the goal of our study, and descriptions of three recent studies conducted by our group on the measurement and analysis of eye movement while viewing movies and the relationship of eye movement with VIMS. First, this study focuses on the relationship between eye movement and motion sickness susceptibility. We investigated the relationship between the motion sickness susceptibility and the frequency of optokinetic nystagmus (OKN) with peripheral viewing.
