  • Publication number: 20240094330
    Abstract: A method and an apparatus for detecting a relative location between devices is disclosed. The detection method includes: obtaining a first target audio signal obtained by a first microphone of a device B; determining a first audio segment and a second audio segment based on a first target moment and the first target audio signal, where the first target moment is a moment determined in the first target audio signal based on a target amplitude; separately searching for the first audio segment and the second audio segment to obtain a first arrival moment and a second arrival moment; and determining a relative location between a device A and the device B based on the first arrival moment and the second arrival moment.

  • Patent number: 11699048
    Abstract: Wireless sensing units, methods, systems, and processor-readable media for obtaining pressure data relating to one or more pressure locations of a surface area are described. A wireless sensing system includes a pressure monitoring device communicating with modular wireless smart floor tiles using RFID, either using an RFID reader or wireless network interface (e.g., 802.11). The tiles incorporate passive or active RFID tags. The tiles can be powered wirelessly, e.g. by a built-in piezoelectric power unit or by a wireless power source using magnetic resonance. A data capture circuit in each tile collects and saves the data for transmission to the floor pressure monitoring device. Various software applications can be enabled by the smart floor system, including fall detection and prediction, gesture input, intrusion detection, and user location tracking for smart home automation.

  • Patent number: 11481035
    Abstract: System and method for managing a user interface for a foldable device are disclosed. The method includes: determining a folding state of the foldable device based on a folding angle of the foldable device; detecting an input gesture on one or more touch-sensitive display segments of a flexible display screen of a foldable device; determining a gesture type corresponding to the detected input gesture; determining whether the detected input gesture is a valid gesture or invalid gesture; and responsive to determining that the detected input gesture is a valid gesture, providing the gesture type corresponding to the detected gesture, the folding state of the foldable device, and display information to a software application or an operating system of the foldable device.

  • Patent number: 11474598
    Abstract: Systems and method for low-power gaze prediction on touch-enabled electronic devices using touch interactions are provided. The method includes receiving an input touch interaction applied to a touch interaction area on a touchscreen display of a touch-enabled device and obtaining, by a gaze prediction module, a predicted gazing area on the touchscreen display based on the input touch interaction. A touch-enabled device has a processor, a touchscreen display and memory storing instructions to carry out the method. The gaze prediction module may utilize a model based on Bayesian inference or convolutional neural networks. Advantageously, gaze prediction is achieved without the use of image-capturing devices and with low power consumption. This can be used to develop intelligent hands-free interactions and personalized recommendation systems.

  • Publication number: 20210349625
    Abstract: A method is provided including generating touch coordinate information corresponding to touch interactions with a touchscreen display of an electronic device and updating information rendered on the touchscreen display in response to determining that the touch coordinate information matches a tool shaft movement gesture corresponding to movement of a touch tool shaft over an area of the touchscreen display. A device is provided, including a touchscreen display comprising a display and a touch sensing system configured to generate signals corresponding to screen touches of the display, a processing device operatively coupled to the touchscreen display, and a non-transitory memory coupled to the processing device and storing software instructions that when executed by the processing device configure the processing device to carry out the provided method. The ability to process tool shaft gestures may improve one or both of the operation of the device and the user experience with the device.
