Patent number: 11829180Abstract: A pressure detection device of detecting a forced state of a deformable object includes a body, an image sensor and a processor. The body is a deformable hollow structure. The body has an inner surface and an outer surface, and an identifiable vision feature is disposed on the inner surface. The image sensor is disposed inside the body and faces the inner surface of the body, and is adapted to capture a frame containing the identifiable vision feature on the inner surface. The processor is electrically connected with the image sensor, and adapted to analyze position variation of the identifiable vision feature within the captured frame for identifying a motion type of a gesture applied to the outer surface of the body.Type: GrantFiled: August 24, 2021Date of Patent: November 28, 2023Assignee: PixArt Imaging Inc.Inventors: Wei-Chung Wang, Hsin-Chia Chen, Hui-Hsuan Chen, Chao-Chien Huang, Chu-Hung Nien

Patent number: 11614805Abstract: A joystick includes a first structural component, a second structural component, a light emitter, an optical sensor and a processor. The second structural component is assembled with the first structural component to form a chamber. The light emitter is disposed inside the chamber for illuminating one surface of the second structural component. The optical sensor is disposed inside the chamber for capturing the illuminated surface of the second structural component. The processor is electrically connected to the optical sensor and adapted to analyze an intensity distribution of the illuminated surface for determining if the joystick is obliquely pressed or laterally shifted in a relative manner.Type: GrantFiled: March 3, 2021Date of Patent: March 28, 2023Assignee: PixArt Imaging Inc.Inventors: Yi-Chung Chen, Chu-Hung Nien
