Patent number: 11853491Abstract: A touch display device (TDD) configured to function with a pointing device (PD), and a method of operating the TDD. The TDD has a processor that automatically determines if the PD is in contact with a touch display (TD) of the TDD or with a surface distinct from the TD. When the PD is in contact with the TD, a toggling signal from the PD may be received at the processor to toggle from a first input mode where a tip of the PD overlaps a visual element displayed on the TD, to a second input mode with the tip of the PD is spaced apart from the displayed visual element. When the PD is in contact with the distinct surface, the processor automatically selects a third input mode where a position of the PD on the distinct surface is reproduced as a position the sign on the TD.Type: GrantFiled: January 11, 2023Date of Patent: December 26, 2023Assignee: HUAWEI TECHNOLOGIES CANADA CO., LTD.Inventors: Da-Yuan Huang, Che Yan, Linghao Du, Wei Li, Daniel John Vogel

Patent number: 11782522Abstract: In various examples, the present disclosure describes methods and systems for generating hand state predictions. A hand state prediction system includes a machine learning-based model, such as a neural network model, that is trained to convert inertial motion measurements and surface contact data into predictions of a corresponding hand gesture or gripping posture. For each window of data sampled, motion data and contact data are obtained, processed and fused to generate a fused prediction. The hand state prediction system can operate in continuous mode to automatically detect a start and an end of a hand action, or a user can designate a start and an end of a hand action. A hand state prediction is generated by a multimodal classifier by processing the fused prediction. Instructions represented by a hand action can be acted upon through a command action performed by a computing device or a computer application.Type: GrantFiled: March 25, 2022Date of Patent: October 10, 2023Assignee: Huawei Technologies Co., Ltd.Inventors: Roya Cody, Da Yuan Huang, Xiang Cao, Wei Li
