“…The near stereoacuity measurements were similar to previously reported. Median distance stereo acuity in this study was 38.4" comparable to 29.6" at 6 meters reported by Adams et al [17] and 37" reported by Zaroff et al [18].…”

Purpose: To evaluate the feasibility of the TNO chart for the assessment of distance stereo-acuity using an inverted telescope in normal subjects.Methods: Stereoacuity of 30 emmetropic adult subjects was measured for near. The distance stereoacuity was measured using the TNO chart held at 40 cm and an inverted telescope (Galilean design, 26mm, 2X, Camma Inc. China) in front of the examinee's eyes. Results:The near stereopsis ranged from 60" (seconds of arc) -240" (Median 120"). Distance stereopsis ranged from 4.8" -38.4". Distance stereoacuity could be measured in 14 (47%) subjects. Conclusion:It is possible to measure the distance with an inverted telescope and a TNO chart. Further improvisation is required to design an optimal telescope system with larger field, gradable zoom and measurable inter pupillary distance.

“…The accommodation control would require adequate fogging in the telescopic system. While, the effect of convergence can be removed by presenting the stimulus for 100ms [18]. Presenting the stimulus for such a short time is certainly possible with the Frisby Davis charts and American Optical charts.…”

“…These findings suggest that the reduction of stereopsis is not associated with the decrease of visual acuity. Zaroff et al 23 applied random dot stereoacuity test and reported that while 88% of under-60-year-old subjects showed normal stereopsis, only 37% of those in their 60s and 25% of those in their 70s did. Hence, the rate of stereopsis defects increased with increasing age.…”

Purpose: Stereopsis in normal subjects aged between 7 and 76 years was compared to examine changes in stereopsis with age. Methods: Eighty subjects with no ocular disease were divided into 8 groups by age. Near stereopsis was evaluated with the TNO, Titmus, and Randot tests; distance stereopsis with the Mentor B-VAT II video acuity tester. Results:The results of all 4 tests showed decreased stereopsis with increasing age (p<0.05). Compared to the stereoacuity of 7 to 10-year-old group, both the TNO and distance stereopsis test results were significantly decreased for the 6th, 7th, and 8th decade groups, while both the Titmus and Randot test results were significantly decreased for the 8th decade group (p<0.05). Conclusions: Overall, both near and distance stereopsis decreased with increasing age. Thus, decreased stereopsis should be taken into account when performing the stereopsis test.

“…This may partly explain why the subjects had more diverse opinions on perceived depth quality and why they felt more comfortable viewing 2D videos. Lastly, humans exhibit a wide range of stereoacuity and stereosense [8], ranging from complete deficiency to better than normal. This ability would naturally affect a subject's impressions of both 3D distortions and comfort.…”

We describe a study that aims towards enhancing our understanding of the perception of H.264/AVC compressed stereoscopic 3D videos, in particular spatial video quality, depth quality, visual comfort and overall 3D video quality. The results of this study indicate that the human subjects have diverse opinions on depth quality scores but a high agreement on spatial video quality. Their agreement on overall 3D video quality is intermediate relative to that on spatial video quality and depth quality. Based on our analysis, we propose to use separate quality assessment models: spatial video quality models and depth quality models.Index Terms-3D video quality, depth quality, comfort visual, 3D video database, psychometrics
