The study on informational compensation environment from the view of wayfinding of informational impairment - Evaluation of visual access on each degree of impairment

本研究对信息损伤的信息补偿环境进行了为期三年的研究。在本研究的过程中，视听障碍患者很难连续参加每一次实验。我们已经开始开发虚拟寻路实验系统(WASS)，并对WASS的再现进行研究。在此基础上，对WASS中不同程度损伤的路径发现实验和信息补偿环境规划的观点进行了研究，并对未来课题进行了研究。具体内容如下：1.不同程度损伤的定向实验基于WASS，历时两年，对不同程度的损伤进行定向实验。具体地说，研究了弱视和雾视障两种情境下的寻路行为和注视行为。2.信息补偿环境的规划观点作为信息补偿环境，研究了信息损害补偿的观点。特别是，我们对寻路的适应过程进行了研究，得出了以下一些发现。在寻路的开始阶段，标志对于寻路是很重要的。空间线索在适应阶段起着重要作用。并将空间线索纳入寻路的锚点。3.未来研究课题在两年的时间里，我们在国际会议上根据国际信息交流进行研究反馈。从国际上看，这项研究被评为该研究领域的先行者。因此，我们只研究了一块试验田，那就是养老院。对于不同环境下的有效性，有必要研究更多的环境，明确信息薪酬环境的普遍趋势。

This research have studied on Informational Compensation Environment for Informational Impairments for three years. In the process of this study, it became difficult for visual and audio impairments to attend the experiments in every times continuously. We have started to develop a virtual experimental system of wayfinding (WASS) and study on the reappearance of WASS. Then, we studied on 1.wayfinding experiment on each degree of impairment in WASS and 2.view points for planning of informational compensation environment, and 3.future subjects. Details are as follows.1.Wayfinding experiment on each degree of impairmentWayfinding experiments on each degree of impairment based on WASS developed for two years. Concretely, two kinds of settings, week sight impairment and fog sight impairment, were studied to make clear the tendency of wayfinding and eye fixation behavior.2.View points for planning of informational compensation environmentThe view points to make compensation for informational impairment were studied as the informational compensation environment. Particularly, we studied the adaptation process of wayfinding, make clear some findings as follows. Sign is important for finding in beginning stage of wayfinding. Spatial cue is important in adapted stage. And Spatial cue is included in the anchor point of wayfinding.3.Future subjectsWe made research feedback based on international informational exchanges in international conferences for two years. From the international view point, this research was evaluated as a forerunner research in this research field. Thus, we studied on only one experimental field, which is a nursing home. It is necessary to study more kinds of environment for the validity in different environment and make clear the universal tendency of informational compensation environment.
