1 1,2 1 (: Head Mounted Display),,,, An Information Presentation Method for Wearable Displays Considering Surrounding Conditions in Wearable Computing Environments Masayuki Nakao 1 Tsutomu Terada 1,2 Masahiko Tsukamoto 1 Abstract: In wearable computing environments, the time duration to gaze a Head Mounted Display () strongly depends on surrounding environmental context. We propose a method that enable users to acquire necessary information safely by changing the presentation method according to context. In this research, we clarify the relationship among surrounding contexts, the condition of gazing at, and eye strain, by using an eye tracker device. Then, we design our method to change the presentation method based on the evaluation results.
