Investigating the Immediate and Cumulative Effects of Isometric Squat Exercise for Different Weight Loads on Intraocular Pressure: A Pilot Study. Sports Health, 11(3), 247-253. https://doi.org/10.1177/1941738119834985

Background: The execution of resistance exercise against heavy loads promotes an acute intraocular pressure (IOP) rise, which has detrimental effects on ocular health. However, the effect of load on the IOP behavior during exercise remains unknown du...

Accommodation and comfort in head-mounted displays (2017)
Journal Article
Koulieris, G.-A., Bui, B., Banks, M. S., & Drettakis, G. (2017). Accommodation and comfort in head-mounted displays. ACM Transactions on Graphics, 36(4), Article 87. https://doi.org/10.1145/3072959.3073622

Head-mounted displays (HMDs) often cause discomfort and even nausea. Improving comfort is therefore one of the most significant challenges for the design of such systems. In this paper, we evaluate the effect of different HMD display configurations o... Read More about Accommodation and comfort in head-mounted displays.

Stereoscopic 3D (S3D) displays provide an enhanced sense of depth by sending different images to the two eyes. But these displays do not reproduce focus cues (blur and accommodation) correctly. Specifically, the eyes must accommodate to the display s... Read More about Focus-tunable and fixed lenses and stereoscopic 3D displays (Conference Presentation).
