Abstract

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for displaying information in various display regions within wearable display devices in a manner that enhances user experience. The wearable display devices may include a flexible display region and may be capable of operating in a wrinkled state. In one aspect, a wearable display device includes a plurality of sensors configured to determine the state of the display. The sensors may, for example, be configured to detect pressure, light, and/or deformation. In some aspects, the device includes a processor configured to provide image data to the display. In some aspects, the processor is capable of changing at least one characteristic of the image data provided to the display based at least in part on input received from the sensors. For example, the processor may re-size an image and/or deactivate a portion of the display.
