Abstract

Abstract Research on elders’ acceptance of virtual technologies is much needed. Here we studied the user experience of elders (N = 10, mean age = 88.2 years) during virtual biking, an exergame where participants pedal on a cycle ergometer and wear a Head-Mounted Display that provides them an immersive experience of a bike ride. We tested the effects of augmented gaze on user experience. Augmented gaze is a condition in which horizontal head turns yield amplified visual shifts, which is assumed to facilitate visual exploration. User experience was measured by asking participants to rate satisfaction, motivation, sense of presence and sense of safety. We found a very good acceptance of virtual biking and no signs of negative effects of augmented gaze. These preliminary observations suggest that augmented gaze may be a viable optimization of elders’ experience with certain virtual reality applications.

老年人对增强凝视的体验:初步观察
摘要 对老年人接受虚拟技术的研究亟待开展。在这里,我们研究了老年人(N = 10,平均年龄 = 88.2 岁)在虚拟骑车过程中的用户体验。在虚拟骑车游戏中,参与者踩在自行车测力计上,并佩戴头戴式显示器,从而获得身临其境的骑车体验。我们测试了增强凝视对用户体验的影响。增强凝视是一种水平转头产生放大视觉偏移的条件,被认为有利于视觉探索。我们通过让参与者对满意度、动力、存在感和安全感进行评分来衡量用户体验。我们发现用户对虚拟自行车的接受度非常高,而且没有迹象表明增强凝视会产生负面影响。这些初步观察结果表明,在某些虚拟现实应用中,增强凝视可以优化老年人的体验。
