Patent number: 10216272Abstract: A strain measurement ring measures strain information describing deformation of a strain-sensitive element included in the strain measurement ring due to movement of a user's finger. The strain measurement ring includes a semi-rigid band coupled to a deformable band, which together encompass a portion of the user's body. The semi-rigid band includes two coupling ends each coupled to a respective coupling end of the deformable band. The deformable band includes the strain-sensitive element. The strain measurement ring may include an emitter to transmit strain information to a virtual reality/augmented reality (VR/AR) console. The strain measurement ring may include an actuator to change the tension of the deformable band in response to haptic command signals from a VR/AR console. As a result, the strain measurement ring may apply pressure to the user's skin to simulate contact with a virtual object.Type: GrantFiled: August 25, 2016Date of Patent: February 26, 2019Assignee: Facebook Technologies, LLCInventors: Sean Jason Keller, David R.

Patent number: 10197459Abstract: A deformation sensing apparatus comprises an elastic substrate, a conductive element, and an additional conductive element. The conductive element includes conductive joints that are separated from each other by resolving elements along a length of the conductive element. Different combinations of conductive joints and resolving elements correspond to different segments of the deformation sensing apparatus. Based on a change in capacitance between a conductive joint and the additional conductive element when a strain is applied to the deformation sensing apparatus, the deformation sensing apparatus generates a signal that allows determination of how the strain deforms the deformation sensing apparatus.Type: GrantFiled: December 16, 2016Date of Patent: February 5, 2019Assignee: Facebook Technologies, LLCInventors: Sean Jason Keller, Tristan Thomas Trutna, David R.

Patent number: 10032347Abstract: A sensor records information about skin stretch perceived by a user based on an interaction with a real object. The sensor includes a mechanical housing configured to be worn on a finger of a user, and a mechanism coupled to the mechanical housing. The mechanism includes a first bearing that rotates in a first direction in response to an interaction with a surface.

Patent number: 10013055Abstract: An eye tracking system, images the surface (e.g., sclera) of each eye of a user to capture an optical flow field resulting from a texture of the imaged surface. The eye tracking system includes illumination source (e.g., laser) and a detector (e.g., camera). The source illuminates a portion of the eye that is imaged the camera. As the eye moves, different areas of the eye are imaged, allowing generation of a map of a portion of the eye. An image of a portion of the eye is includes a diffraction pattern (i.e., the optical flow) corresponding to the portion of the eye. Through a calibration process, the optical flow is mapped to a location where the eye is looking.Type: GrantFiled: November 4, 2016Date of Patent: July 3, 2018Assignee: Oculus VR, LLCInventors: David R.

Patent number: 9971410Abstract: An actuator configured to provide haptic feedback to a user. The actuator is located on a plate and is configured to apply various excitations to the plate to generate a mechanical wave propagating in the controlled direction. The excitations can be a translational motion of the actuator (or a portion of the actuator) in two or three perpendicular axes. Alternatively, the excitations can be a non-translational motion (e.g., rotation about an axis) of the actuator (or a portion of the actuator). By generating the mechanical wave traveling in the controlled direction, loss of energy due to scattering of the mechanical wave can be obviated.Type: GrantFiled: August 24, 2017Date of Patent: May 15, 2018Assignee: Oculus VR, LLCInventors: Sean Jason Keller, Tristan Thomas Trutna, Ravish Mehra, Christoph Omid Hohnerlein, Elia Gatti, Riccardo DeSalvo, David R.
