Patent attributes
One embodiment of the present disclosure sets forth a technique for delivering audio output and generates haptic sensations on or proximate to objects in an environment via which a user can perceive haptic sensations. The device includes transducer arrays that operate in various modalities, including generating audio output, generating haptic output, and sensing objects in the environment. When generating audio output, the transducer arrays produce ultrasonic waves that demodulate to produce audio output. When generating haptic output, the transducer arrays output directional haptic output to various locations to the environment using constructive and/or destructive interference. When sensing objects in the environment, the transducer arrays generate pings and detect ping echoes reflected off of objects in the environment.
