Visual Field Testing with Head-Mounted Perimeter ‘imo’
PURPOSE We developed a new portable head-mounted perimeter, "imo", which performs visual field (VF) testing under flexible conditions without a dark room. Besides the monocular eye test, imo can present a test target randomly to either eye without occlusion (a binocular random single eye test). The performance of imo was evaluated. METHODS Using full HD transmissive LCD and high intensity LED...
متن کاملEffects of head tilt on visual field testing with a head-mounted perimeter imo
PURPOSE A newly developed head-mounted perimeter termed "imo" enables visual field (VF) testing without a fixed head position. Because the positional relationship between the subject's head and the imo is fixed, the effects of head position changes on the test results are small compared with those obtained using a stationary perimeter. However, only ocular counter-roll (OCR) induced by head til...
متن کاملAmplifying Head Movements with Head-Mounted Displays
The head-mounted display (HMD) is a popular form of virtual display, due to its ability to immerse users visually in virtual environments (VEs). Unfortunately, the user’s virtual experience is compromised by the narrow field of view (FOV) it affords, which is less than half that of normal human vision. This paper explores a solution to some of the problems caused by the narrow FOV, by amplifyin...
متن کاملPerceptual Issues in the Use of Head-Mounted Visual Displays
OBJECTIVE We provide a review and analysis of much of the published literature on visual perception issues that impact the design and use of head-mounted displays (HMDs). BACKGROUND Unlike the previous literature on HMDs, this review draws heavily from the basic vision literature in order to help provide insight for future design solutions for HMDs. METHOD Included in this review are articl...
متن کاملEstimating Visual Discomfort in Head-Mounted Displays Using Electroencephalography
Head-Mounted displays, while providing unprecedented immersiveness and engagement in interaction, can substantially add mental workload and visual strain on users. Being a novel technology, users often do not know what to expect and therefore accept visual stress as being state of the art. Assessing visual discomfort is currently possible through questionnaires and interviews that interrupt the...
