In particular, the technology disclosed uses a Fresnel prismatic element and/or a triangular prism element to redirect the optical axis of the cameras, giving the cameras fields of view that cover at least 45 to 80 degrees from tangential to the vertical axis of a display screen on which the cameras are mounted.Type: GrantFiled: March 1, 2021Date of Patent: September 6, 2022Assignee: Ultrahaptics IP Two LimitedInventors: David S.

Patent number: 11416079Abstract: A method including capturing a series of image frames of a hand. The method includes generating a map of hand landmarks for each in the series of image frames. The method includes determining whether the maps of hand landmarks include at least: (i) a first map that matches a first reference map of hand landmarks representing a hand in substantially a start position of a snap motion and (ii) a subsequent, second map that matches a second reference map of hand landmarks representing a hand in a progressed (e.g., intermediate or end) position of a snap motion. The method includes determining that a finger-snap gesture is detected in response to determining that the first map and second map were generated from image frames captured within a snap time limit; and executing an action corresponding to a determination that a finger-snap gesture is detected in the series of image frames.Type: GrantFiled: December 3, 2020Date of Patent: August 16, 2022Assignee: Motorola Mobility LLCInventors: Amit Kumar Agrawal, Xin Zhao, Yonghua Hu

Patent number: 11409371Abstract: Systems and methods for gesture-based control are described. In some embodiments, a system may include a device configured to be worn at a person's wrist. The wearable device may include a biopotential sensor, a wrist location sensor, and a wireless transmitter. The system may have a first state and a second state. In the first state, the system may be configured to classify first data based on an output from the wrist location sensor to detect a wake word gesture. In the second state, the system may be configured to classify second data to detect a second gesture, the second data being based on both wrist location data and biopotential data. The system may be configured to transition from the first state to the second state based, at least in part, on a detection of the wake word gesture.Type: GrantFiled: August 31, 2021Date of Patent: August 9, 2022Assignee: Pison Technology, Inc.Inventors: Dexter W. Ang, David O. Cipoletta
