Abstract:
1. An electronic paper display device, comprising: a light sensor to measure a light intensity of ambient light; memory to store instructions that, when executed on one or more processors, are operable to cause the light sensor to measure the light intensity of the ambient light in response to receiving a user request to turn a page; an electronic paper display configured to present a visual representation of content by selectively moving particles through associated capsules, each particle and associated capsule representing a pixel of the content and the capsules being aligned substantially perpendicular to a display surface of the electronic paper display; and a display controller in communication with the electronic paper display and the memory to adjust the movement of the particles based at least in part on the light intensity value, wherein the display controller selects a waveform corresponding at least in part, to the light intensity value to adjust a contrast of rendered content, the waveform comprising an input that determines a duration of the movement of the particles, the display controller further implementing a page turn duration based at least in part on the waveform, the page turn duration corresponding to a maximum movement of the particles that are selectively moved in the electronic paper display.
