Heads up display for swimming goggles

Methods for providing swimmers with performance metrics, turn detection, and stroke rate detection are disclosed. An example method comprises mounting a wearable device comprising an accelerometer, gyroscope and processor on a swimmer's head, continuously measuring acceleration using said accelerometer and angular velocity using said gyroscope to provide acceleration and angular velocity signals to said processor, processing said acceleration and angular velocity signals to determine first roll and pitch angles, applying a correction to axes of said gyroscope based on said roll and pitch angles to determine corrected angular velocity signals, initializing a heading angle at a pre-defined, non-zero value, integrating said corrected angular velocity signals over a time window to determine changes to the heading angle, determining maximum and minimum heading angles within the time window, and, recording a turn when a difference between the maximum and minimum heading angles within the time window is at least approximately 180 degrees.

Methods and systems for swimming performance analysis

The present disclosure provides a near-eye display system for generating a virtual image of a display, including: a display, a first lens array comprising a plurality of concave microlenses having a first pitch, and a second lens array positioned in front of the first lens array, the second lens array comprising a plurality of convex microlenses having a second pitch, wherein the first lens array is positioned on an optical path between the display and the second lens array, and wherein the first lens array has a focal plane at the display and the second lens array has a focal plane at a virtual image plane of the first lens array.

Near-eye display system

Swimming goggles with heads-up display

The present disclosure provides a heads up display (HUD) system configured for use with a pair of swimming goggles comprising first and second eye cups, a nose bridge connected to inner sides of the eye cups, and strap mounting portions on outer sides of the eye cups. The HUD system comprises an electronics and optics modules. The electronics module comprises a water tight housing and a processor, memory, power supply, sensors and a display within the water tight housing. The processor processes signals from the sensors to determine swimming performance data and controls the display to generate an image containing the swimming performance data. The optics module is mounted on one of the eye cups and is coupled to the electronics module for receiving the image from the display. The optics module extends from the electronics module and has one or more light directing features for redirecting the image toward an eye of a user to generate a redirected image.

The present disclosure provides a jump detection system for inertial measurement unit (IMU) integrated with a barometric altimeter in the same device (IMU-baro). The processor is configured to record time-series data of both a vertical component of the measured IMU-baro acceleration and the estimated vertical velocity of the IMU-baro, detect a potential jump by comparing the vertical component of the measured IMU-baro acceleration to one or more acceleration thresholds, and, validate the potential jump by comparing a difference between a maximum velocity and a minimum velocity within a vicinity of the potential jump in the time-series data of the estimated vertical velocity of the IMU-baro to a velocity threshold.

Methods and systems for vertical trajectory determination and automatic jump detection

This disclosure provides a vertical position and velocity determination system for inertial measurement unit (IMU) integrated with a barometric altimeter in the same device (IMU-baro). The system includes a rate of turn input connected to receive a measured IMU-baro rate of turn; an acceleration input connected to receive a measured IMU-baro acceleration; a barometric pressure input connected to receive a measured IMU-baro altitude; a first Kalman filter connected to the rate of turn input and to the acceleration input to estimate a roll and pitch of the IMU-baro based on the measured IMU-baro rate of turn and the measured IMU-baro acceleration; and a second Kalman filter connected to the acceleration input, to the barometric pressure input, and to the first Kalman filter.
