Abstract: Methods and apparatus for determining spin of a golf ball in flight. At least a portion of an observed trajectory of the golf ball and one or more parameters associated with the trajectory are obtained. The parameters are selected from launch angle, ball speed, club speed and ball carry. Two or more spin candidates are obtained for the golf ball. Each spin candidate has an associated probability. A most probable used golf club for launching the golf ball into the observed trajectory is determined by matching the observed parameters with parameters for two or more different golf clubs. Ball spin probability data are obtained for the most probable used golf club. The spin of the golf ball is the most probable spin candidate, based on the ball spin probability data and the observed trajectory. The determined spin of the golf ball is displayed on a display device.

Abstract: A method for determining a gaze convergence function for a user of an eye tracking system. The method comprising presenting a first calibration object to the user on one or more display screens, wherein the first calibration object appears to be at a known first object distance from the user. While the first calibration object is being presented, the method: captures a calibration images of the user's eyes and calculates a first interpupillary distance, IPD, value. The method performs similar processing steps for a second calibration object to calculate a second IPD value. The method then determines a gaze convergence function which defines a relationship between IPD values and gaze convergence distances based on: i) the first IPD value and the associated first object distance; and ii) the second IPD value and the associated second object distance.

Abstract: An eye tracking system comprises at least one illuminator and at least one image sensor configured to produce an image of an eye of a user, the image including illuminator light reflected from the eye of a user. A Fresnel lens is positioned between the image sensor and the eye of the user, through which the image sensor views the eye. Processing circuitry receives an image from the image sensor, identifies glints in the image, assigns an angular position to each glint based on an angular relationship between each glint and a centre of the Fresnel lens and determines how many glints have the same angular position. Glints are classified as false glints if more than a predetermined number of glints have the same angular position.
