AUgmented REality for the Visually Impaired - Part 1

"In this testing session, the patient's visual comfort threshold related to light intensity will be determined. Test sessions are kept under 45 minutes.~The subject is sitting in front of a keyboard and a computer screen. He/she is invited to recognize letters successively displayed in the center of the screen, this center is marked with a black cross. Each letter appearance is preceded by a beep. The subject must click on the space bar on the keyboard as soon as he/she recognizes the letter, then gives his/her answer orally."

For these tests, the subject is seated at a table, 1.5m from a wall. It features a computer keyboard. It projects an image on the wall, using to a video projector. An image moving towards a target (along 16 different trajectories) is used to evaluate the size of the visual field.

"During this testing session, the investigators seek to evaluate the effectiveness of the algorithms used to control the brightness.~The subject is in a room with four different computers. The subject is asked to identify the objects displayed on different computer monitors in the room: he/she must press a key on the keyboard when he/she detects an object and state aloud the nature of the object."

"During this session, the investigators try to assess the performance for the color vision correction (saturation and hue).~The subject, while wearing the virtual reality glasses + camera performs a test (twice) that requires matching colored dots (i.e. a Farnsworth test) under controlled light conditions."

The other interventions are performed with the use of virtual reality glasses, specifically the Vuzix Wrap 1200DX. In case of technical difficulties, the latter can be swapped with the Oculus Rift model or another model. The associated webcameras are from Logitech, and the exact model used can vary and does not carry any importance for this research.
