Abstract: Systems and methods for motion attribute recognition are defined using data stream pre-processing to orient, align and segment motion data before using non-parametric classification recognition to search a motion data exemplar database or using parametric classification recognition to find attributes by comparing pre-processed motion data with support vector machines. Results from the non-parametric classification recognition and the parametric classification recognition may be fused to produce a single result. Active learning and metric learning are used to improve searches of the database and comparisons to the support vector machines.

Abstract: An apparatus, system and method for golf swing analysis is described using a first microprocessor, a three-axis accelerometer that transmits linear acceleration data to the first microprocessor, a three-axis gyroscope that transmits angular velocity data to the first microprocessor, data processing, a radio transmitter for transmitting processed data, and a housing for holding the components, which attaches to a golf club. A camera with image recognition software and an ultrasonic and RF navigation system are used for error correction. A camera on the portable device may be used to capture video, which is trimmed to correspond with the animation, and the video may be placed side by side with the animation for visual analysis. Further error correction occurs using image sensors to determine moving object speeds and coordinates.

Abstract: An apparatus and method for golf swing analysis is described using a first microprocessor, a three-axis accelerometer capable of transmitting linear acceleration data to the first microprocessor, a three-axis gyroscope capable of transmitting angular velocity data to the first microprocessor, data processing, a radio transmitter for transmitting processed data, and a housing for holding the components, which attaches to a golf club. A three-axis magnetometer capable of transmitting directional orientation data to the first microprocessor is used to allow a user to choose a target line. Communication occurs between the apparatus and a portable device with a radio receiver, memory and a computer program that processes the data into graphical data and statistical data and displays the swing graphically after a user swings the golf club. The user will be able to analyze and try to improve his or her golf swing.
