简要总结
The main objective of this study is to quantify vision parameters in subjects with concentric visual field constriction, and this in relation to the display on virtual reality goggles. More specifically:
- The maximum brightness value for visual comfort (THRESHOLD_MAX)
- The minimum value of the perceptible light contrast in low light perceptible (THRESHOLD_MIN)
- The speed of light change adaptation in the range [THRESHOLD_MAX-THRESHOLD_MIN] and [THRESHOLD_MIN-THRESHOLD_MAX].
详细描述
Secondary objectives are to: A. Quantifying the device parameters "RV glasses + camera" depending on visual acuity and the visual field of each subject: * Optimal extent of the visual field provided by the device "RV glasses + camera". B. Measuring the effectiveness of different image processing algorithms used in the development of the software part of this technical assist device: * Capture and display HDR images (High Dynamic Range) * Color adjustment.
