Abstract: Techniques for providing adaptive assistive technology for assisting users with visual impairment can be used on a computing device. These techniques include displaying content to a user, capturing a series of images or video of the user using a camera, analyzing the series of images or video to determine whether the user is exhibiting behavior or characteristics indicative of visual impairment, and rendering a magnification user interface on the display configured to magnify at least a portion of the content of the display based on a determination that the user is exhibiting behavior or characteristics indicative of visual impairment. The magnification user interface may be controlled based on head and/or eye movements of the user of the computing device.

Abstract: Adaptive assistance technologies can assist a user with operating a computing device. A method according to these techniques includes analyzing user interactions with the computing device, determining that the user interactions with the computing device are indicative of a user experiencing one or more issues for which adaptive assistive technologies provided by the computing device may assist the user, identifying one or more assistive technologies provided by the computing device that may address the one or more issues, modifying one or more operating parameters of the computing device using the one or more assistive technologies, and operating the computing device according to the one or more modified operating parameters.

Abstract: Certain examples provide photometric or radiometric calibration using optical feedback. A disclosed example includes dithering between a first display pixel value and a second display pixel value to create a light source from a display. The disclosed example includes capturing the light source using a camera via a plurality of photographs taken by the camera. Each photograph includes a plurality of camera pixels. The disclosed example includes determining a camera response by measuring plurality of camera quantization levels associated with the plurality of camera pixels based on the first display pixel value and the second display pixel value. The disclosed example also includes determining a display response based on the plurality of camera quantization levels. The display response includes a plurality of luminance output values of the display.
