Techniques for image enhancement using a tactile display

Abstract

Techniques are disclosed for enhancing the quality of a displayed image using a tactile or other texture display. In particular, the disclosed techniques leverage active-texture display technology to enhance the quality of graphics by providing, for example, outlining and/or shading when presenting a given image, so as to create the effect of increased contrast and image quality and/or to reduce observable glare. These effects can be present even at high viewing angles and in environments of high light reflection. To these ends, one or more graphics processes, such as edge-detection and/or shading, may be applied to an image to be displayed. In turn, an actuator element (e.g., microelectromechanical systems, or MEMS, devices) of the tactile display may be manipulated (e.g., in Z-height) to provide fine-grain adjustment of image attributes such as: pixel brightness/intensity; pixel color; edge highlighting; object outlining; effective shading; image contrast; and/or viewing angle.
