| Summary: | 碩士 === 明志科技大學 === 工業工程與管理系碩士班 === 107 === This study uses a Nintendo 3DS game console with 2D and autostereoscopic 3D techniques as the interfaces. The current research explored age, background music and display interface for baseball game player on signal detection theory (SDT), β value, d' value, ROC curve, visual fatigue and presence through experimental design. Thirty participants were recruited in our mixed factorial design to explore different ages (young adults group, middle-aged group, senior citizens group), background music (none, light, pop, rock) and display interface (2D, autostereoscopic 3D) for the four possibilities of SDT (hit, miss, false alarm, correct rejection), β value, d' value, ROC curve, Simulator Sickness Questionnaire (SSQ), and Igroup Presence Questionnaire (IPQ).
The results indicated that age was significant on hit rate, miss rate, false alarm, correct rejection, β value and d' value, where higher hit, false alarm rate, d' value and lower β value were found in young adults group, as well as where lower hit, false alarm rate, d' value and higher β value were found in senior citizens group. The results also indicated that background music was significant on hit, miss, false alarm, correct rejection rate, β value and SSQ, where lower hit rate and higher visual fatigue were found in rock music. The results further showed that display interface was significant on hit, miss rate, β value, SSQ and IPQ, where higher hit rate, visual fatigue, and IPQ were found in 3D technique. The ROC curve showed that young adults group had higher correct rate on the strike and predicting the ball was discriminating, senior citizens group had lower correct rate on the strike and predicting the ball was less discriminating. To sum up, this study indicated that the elderly using 2D interfaces had the better performance than using 3D interfaces, so we suggest that the 2D interfaces are more suitable for the elderly. This study also pointed out that the elderly playing baseball games prefer light and pop music instead of rock music. The results of this study can be used as a reference as the design of baseball games for the elderly.
