    Abstract: An autostereoscopic 3D display system includes a display having a plurality of pixels, wherein each pixel is configured to display light rays representing a left-eye view and a right-eye view of an image. The autostereoscopic 3D display system further includes an optical-deflection system configured to control the light rays representing the left-eye view and the right-eye view. The optical-deflection system includes a separately controllable lenslet associated with each pixel, where the lenslet is configured to steer the light ray representing the left-eye view corresponding to the pixel, and steer the light ray representing the right-eye view corresponding to the pixel.

    Abstract: Described embodiments include a system and a method. A system includes an ultrasound transmitter acoustically coupled to an ultrasound-conducting layer of a display surface and configured to deliver a down-modulated ultrasound wave to a first delineated area of at least two delineated areas of the display surface. The down-modulated ultrasound wave when delivered having a power density producing a stress pattern directly perceivable or discernible by a human appendage touching the first delineated area. The system includes a controller configured to initiate a delivery of the down-modulated ultrasound wave to the first delineated area by the ultrasound transmitter in response to an indication of a detected touch by the human appendage to at least a portion of the first delineated area.
