Abstract: The present invention relates to apparatus for simulating visual impairment of a person. The apparatus for simulating visual impairment of a person comprises a headset and a position sensor. The headset comprises a display which displays a virtual scene to a user when the headset is worn by the user. The position sensor senses position of the worn headset and provides an output of the position sensed. The position sensed by the position sensor comprises rotation and translation of the worn headset. The headset displays a continuously changing virtual scene to the user in dependence on the output of the position sensed. The display is controlled such that at least one of saturation and contrast of the continuously changing virtual scene is lower than a level perceived by a visually unimpaired person.

Abstract: The present invention relates to apparatus for simulating visual impairment of a person 10. The apparatus for simulating visual impairment of a person 10 comprises a headset 14 and a position sensor 16. The headset 14 is worn by a user and displays a scene 20 to the user. The position sensor 16 senses the position of the headset. The headset 14 changes the scene 20 displayed to the user in dependence on an output from the position sensor 16. The headset 14 also changes an extent of obscuration of the scene 20 displayed to the user in dependence on an output from the position sensor 16.
