Embodiments are directed to a near eye display (NED) system for displaying artificial reality
content to a user. In some embodiments, multiple users may be in a local area, each using a …

Described herein are techniques for tracking objects (including human body parts such as a
hand), namely: 1) two-state transducer interpolation in acoustic phased-arrays; 2) …

Embodiments are directed to a near eye display (NED) system for displaying artificial reality
content to a user and to manipulate displayed content items based upon gestures performed …

Described is a system for producing an acoustic field from a plurality of ultrasonic transducer
arrays, each of which has known relative positions and orientations. The acoustic field …

A phased array of ultrasonic transducers may create arbitrary fields that can be utilized to
manipulate fluids. This includes the translation of drops on smooth surfaces as well …

The present disclosure concerns a method and apparatus for the creation of an acoustic
field for providing tactile sensa tions. More particularly, but not exclusively, this disclosure …

To resolve an issue related to the calibration of optical cameras in transducer-based mid-air
haptic systems, the magnification of the motion induced on an optical camera by an acoustic …
