Abstract

Magnification around the most important point of a movie scene (center of interest-COI) might aid people with visual impairments that cause resolution loss. This will be effective only if most people look at the same place when watching a movie. We recorded the eye movements of 20 normally sighted subjects as each watched six movie clips, totaling 37.5 min. More than half of the time the distribution of subject gaze points fell within an area statistic that was less than 12% of the movie scene. Male and older subjects were more likely to look in the same place than female and younger subjects, respectively. We conclude that the between-subject agreement is sufficient to make the approach practical.

摘要

放大电影场景最重要的点(兴趣中心 - COI)周围的区域,可能会帮助那些因视力障碍而导致分辨率下降的人。只有当大多数人在观看电影时看向同一个地方,这种方法才会有效。我们记录了20名视力正常的受试者在观看六个电影片段时的眼动情况,总时长为37.5分钟。超过一半的时间里,受试者注视点的分布落在一个面积统计值小于电影场景12%的区域内。男性受试者和年龄较大的受试者比女性受试者和年龄较小的受试者更有可能看向同一个地方。我们得出结论,受试者之间的一致性足以使这种方法具有实用性。
