Abstract
A system may include a display, a haptic feedback system including ultrasonic transducers, a gesture recognition system, and a processor. The processor may be configured to output a stream of graphical data to the display, output a stream of haptic feedback data to the haptic feedback system, and output user-manipulatable region data to the gesture recognition system. The display may be configured to present a stream of images. The ultrasonic transducers may be configured to form an ultrasonic acoustic field in front of the display. The gesture recognition system may be configured to recognize a user gesture in the user-manipulatable region as a user input and to output gesture recognition data to the processor. The processor may be further configured to update the stream of graphical data and the stream of haptic feedback data based at least on the gesture recognition data.
