ความล้าของตาและจิตใจจากการใช้แว่นสามมิติแบบสเตอริโอสโคปิค / สุชามาศ วรรณภาพร = Visual and mental fatigue from using 3D stereoscopic glasses / Suchamas Wannapaporn
3D technology was a part of producing realistic graphics and was developed to be the stereoscope which was a new invention could take photographic images in 3D. It becomes very well known now because users like more 3D environments complete with realistic lighting and complicated simulation of real-life graphics grace on screens but a problem is visual fatigue may occur to users from long period watching. A comparison of fatigue occurred while watching the 2D and 3D system and finding the appropriate watching and resting period for reducing the fatigue. Seven volunteers with average age 23 years were chosen for this study. The conditions were typing with computer, playing a game and watching a movie in 2D or 3D system with 30, 60 or 90 minutes cross with rest 5 or 15 minutes. The fatigue level was measured by the critical flicker frequency, bicolor intensity from the visual signal detection and the questionnaires. The results from the critical flicker frequency and the visual signal detection were similar. It was concluded visual and mental fatigue was apparent even with 30-minuted operation of all tasks but the most fatigue caused by watching a 3D movie and it could be recovered after a rest of 15-minuted. For the results from the questionnaires showed that the symptoms were burning sensation, headache, eye pain and frequent blinking caused by watching 3D movies the most. Moreover, the mental fatigue from playing a 3D computer game was found to be the most.
