Sage Journals: Discover world-class research

Abstract

This study focused on determining and minimizing the effects of motion sickness caused by feelings of vection during the use of magnification assistive technology (AT) products by the visually impaired. A prototype was developed that minimized hypothesized causes of vection in current magnification products. Data were collected from respondents to determine their current use, satisfaction and sickness levels when using magnification AT products. Participants then interacted with the prototype and similar data were collected. Results indicated that the prototype significantly reduced feelings of sickness and vection as compared to conventional AT magnification devices. Further research is warranted on other aspects of such devices that may contribute to adverse side effects.
