PURPOSE To compare action spectra for visual discomfort in the fovea and the parafovea and to determine the effect of macular pigment (MP). METHODS Visual discomfort thresholds to lights from 440 to 600 nm were obtained for six young (<35 y), visually normal subjects with a wide range of MP densities (0.10-0.71 at 30' eccentricity). Foveal and parafoveal conditions were assessed. Discomfort t...

Automatic prediction of visual discomfort for stereoscopic videos is important to address the viewing safety issues in stereoscopic displays. In literature, disparity and motion characteristics have been known as major factors of visual discomfort caused by stereoscopic content. For developing an algorithm to accurately predict visual discomfort in stereoscopic videos, this study investigates h...

OBJECTIVES Fatigue is a prominent symptom in many rheumatic diseases and has a substantial impact on many outcomes. In previous research, fatigue has been linked with poor sleep and discomfort, including joint pain and sicca symptoms. The aim of the present study was to investigate prospectively the daily variations in fatigue and the roles of discomfort and adequacy of sleep the previous night...

Evaluating physical discomfort of designed gestures is important for creating safe and usable gesture-based interaction systems; yet, gestural discomfort evaluation has not been extensively studied in HCI, and few evaluation methods seem currently available whose utility has been experimentally confirmed. To address this, this study empirically demonstrated the utility of the subjective rating ...
