==Stereoscopic 3D benefits and visual discomfort== | |||
When compared to standard 2D TV, the S3D-TV technology enhances the entertainment value of television programs. While the main benefit of 3D-TV is the greater depth perception, there is evidence that stereoscopic television could also enhance the perception of sharpness, sense of presence, and naturalness. According to some surveys, it seems that people would rather view S3D images than 2D, provided that there are no uncomfortable side effects <ref name=”2”></ref>. | |||
In games, the use of stereoscopy seemed to increase immersion and spatial presence. Although the effects differed between games, it seems that the use of S3D allows for a more natural and engaging experience <ref name=”3”></ref>. | |||
One of the concerns regarding S3D technology relates to visual comfort. This has been a long-standing problem in stereoscopic research. It refers to the subjective sensation of discomfort associated with the viewing of stereoscopic images. This issue is not recent; in the past (mainly in the early 1950’s), there were some attempts to popularize 3D movies. These did not succeed due to the limited stereoscopic technology available at the time and to visual discomfort (2). Current stereoscopic displays with a fixed screen plane can cause several human visual cues to conflict with each other, mainly accommodation and convergence. This leads to a negative experience associated with symptoms of visual fatigue like sore eyes, eye strain, headache, and blurred vision. In HMDs this effect also occurs. It has to be noted that the presence and intensity of the visual discomfort varies from person to person <ref name=”3”></ref>. | |||
