• The present study examined the effects of weight balance in a shutter type glasses for 3D TV.
• Four 3D glasses with Front, Middle, Ear, and Rear weight concentrations were investigated.
• Overall Discomfort and Nose Discomfort for Front were significantly higher than other evaluation conditions.
• Nose Load for Front was significantly higher than Middle, Ear, Rear, and Reference.
• Overall Discomfort and Nose Discomfort were strongly tied with Nose Load by a correlation analysis.
A two-phase experimental study examined the effects of weight balance in 3D TV shutter type glasses by subjective discomfort and physical contact load on the nose. Four 3D glasses with different weight-concentrated locations (Front, Middle, Ear, and Rear) and one Reference glasses were investigated. Subjective discomfort ratings on the overall, nose, and posterior edge of the ear were obtained using a 100 point visual analogue scale, and physical load on the nose was measured by force sensing resistor (FSR) film sensors. The overall and nose discomforts for Front were significantly higher than other conditions; the ear discomfort for Ear was significantly worse than the others. The nose load for Front (0.34 N) was significantly higher than Middle (0.22 N), Ear (0.20 N), Rear (0.16 N), and Reference (<0.05 N). A correlation analysis presented that the overall and nose discomforts were closely related (r > 0.9) to the nose load.Relevance to IndustryEffects of weight balance in 3D TV shutter type glasses were examined in terms of subjective discomfort and physical nose load. Overall discomfort and physical nose load significantly declined while the weigh-concentrated location moved from the front to the rear of temples.
