  • Patent number: 11971951
    Abstract: Systems and methods which provide a motion sensor data-driven framework for sports action recognition and/or assessment using a wearable sensor are described. A motion sensor data-driven system may provide real-time kinematical analysis to athletes engaged in active competition or training sessions under typical competition or training conditions. Analysis of motion sensor data provided according to embodiments may operate to recognize instances of one or more particular sports actions performed by an athlete and/or assess the skill of the athlete from analysis of one or more sports actions. A motion sensor data processing platform of embodiments of a motion sensor data-driven system may comprise a processor-based system configured to receive and analyze data regarding the movement of an athlete's limb reported by a wearable sensor device comprising a micro inertial measurement unit configuration for capturing and reporting data regarding the movement of an athlete's limb.

  • Publication number: 20090183929
    Abstract: A Micro Inertial Measurement Unit (IMU) which is based on MEMS accelerometers and gyro sensors is developed for real-time recognition of human hand motions, especially as used in the context of writing on a surface. Motion is recorded by a motion/acceleration sensor, which may be a combination of a rate rate gyro and an accelerometer, and possibly in combination with a video camera set to detect markers located on a board, with the camera utilizable to detect lines and markers and to determine the proximity of the white board. The immediate advantage is the facilitation of a digital interface with both PC and mobile computing devices and perhaps to enable wireless sensing.

  • Patent number: 7508384
    Abstract: A Micro Inertial Measurement Unit (IMU) which is based on MEMS accelerometers and gyro sensors is developed for real-time recognition of human hand motions, especially as used in the context of writing on a surface. Motion is recorded by a rate gyro and an accellerometer and communicated to a Bluetooth module, possibly to a computer which may be 20 to 30 feet or more from the sensor. The motion information generated and communicated is combined with appropriate filtering and transformation algorithms to facilitate a complete Digital Writing System that can be used to record handwriting on any surface, or on no surface at all. The overall size of an IMU can be less than 26 mm×20 mm×20 mm, and may include micro sensors, a processor, and wireless interface components. The Kalman filtering algorithm is preferably used to filter the noise of sensors to allow successful transformance of hand motions into recognizable and recordable English characters.
