Abstract / Description: 

After 25 years of commercial development of head-mounted displays (HMD) we seem to be approaching a point of maturation of the technology that will finally penetrate the market place. The presentation of images in near eye displays whether monocular, binocular, stereoscopic, or see-through for augmented vision has important consequences for the visual experience and of particular importance for the technology success is the comfort and safety of the users. I will discuss the ophthalmic consequences of HMDs that has been suggested, and the evidence collected so far. A major concern has been the decoupling of accommodation and convergence in (stereo and non-stereo) HMD that is presumed to cause eye strain and lead to numerous technological approaches to overcome. Motion sickness like symptoms are common with HMDs and with non-HMD stereo displays, but have been addressed to a much lesser extent. Other visual phenomena and visual challenges presented by HMDs will be presented as well.

Eli Peli is trained as an Electrical Engineer and an Optometrist. He is the Moakley Scholar in Aging Eye Research at Schepens, Massachusetts Eye and Ear, and Professor of Ophthalmology at Harvard Medical School. Dr. Peli is a Fellow of the American Academy of Optometry, the Optical Society of America, the Society for Information Display, and The International Society of Optical Engineering. He was presented the 2010 Otto Schade Prize from the SID (Society for Information Display) and the 2010 Edwin H Land Medal awarded jointly by the Optical Society of America and the Society for Imaging Science and Technology. His principal research interests are image processing in relation to visual function and clinical psychophysics in low vision rehabilitation, image understanding and evaluation of display-vision interaction. He also maintains an interest in oculomotor control and binocular vision. Dr. Peli is a consultant to many companies in the ophthalmic instrumentation area and to manufacturers of head mounted displays (HMD).
