Abstract

A system for recording and analyzing an activity, such as a golf activity, is provided. The system comprises an impact detection device and one or more video capture unit for recording and displaying recorded activities. Preferred activities are saved, and may be viewed at a separate viewing unit located remote from the video capture unit. The remote viewing unit allows for replay and analysis of the saved activities. In addition, saved activities and data may be uploaded to the Internet for later viewing and analysis.

Claims

1. A sport activity impact detection and image recording system comprising:

an impact detection device comprising;

a piezoelectric transducer for producing an electrical signal in response to impact;

a monitoring circuit;

a wireless transceiver for transmitting at least one impact detection signal containing impact notification data;

at least one portable camera device comprising;

a camera to capture a video of the sports activity;

a wireless transceiver to receive said impact detection signal containing impact notification data from the impact detection device;

a processor that performs functions comprising;

receiving the video from the camera;

receiving the impact detection signal and processing the impact notification data from the wireless transceiver;

saving a video in slow motion or normal speed;

concatenating a plurality of the video to make a single video for purposes of review, comment and sharing;

saving the video in local memory or on a server;

saving the impact notification data along with the video;

executing an application program to allow interaction with the camera, wireless transceiver and impact detection device;

wherein upon detection of impact by the monitoring circuit, the impact detection device transmits the impact notification data wirelessly;

wherein the at least one portable camera device upon receiving impact notification from the impact detection device can record a video of sport activity around the time of impact;

wherein the monitoring circuit comprises;

an analog to digital convertor to translate the signal provided by the piezoelectric transducer into a digital signal;

a microprocessor performing one or more functions in a group comprising;

run algorithms to detect impact;

communicate the impact detection signal to the portable camera device wirelessly;

communicate user input to the portable camera device wirelessly;

wherein the impact detection is determined by a signal to noise ratio of the input data provided by the analog to digital convertor exceeding a specified threshold.

2. The system of claim 1, wherein the impact detection device can be attached to a players body.

3. The system of claim 1, wherein the impact detection device can be attached to the sports equipment.

4. The system of claim 1, wherein the duration of the video of sport activity taken before the time of impact is user configurable.

5. The system of claim 1, wherein the duration of the video of sport activity taken after the time of impact is user configurable.

6. The system of claim 1, wherein the portable camera device records video at a user configurable video frame rate.

7. The system of claim 1, wherein the impact notification data being sent includes one or more elements selected from a group comprising:

time of impact;

notification of impact detection;

impact related information.

8. The system of claim 7, wherein the impact related information includes one or more elements selected from a group comprising:

amplitude of the impact;

signal to noise ratio of the piezeoelectric signal generated from the impact.

9. The system of claim 7, wherein the impact related information is saved along with the corresponding saved video.

10. The system of claim 1, wherein the processor operates on the impact notification data and generates a performance value comprising:

force value;

speed;

acceleration.

11. The system of claim 1, wherein the at least one portable camera device captures a still image at a plurality of user configurable pre-determined times around the time of impact.

12. The system of claim 11, wherein impact related information is saved along with the still images.

13. The system of claim 1, wherein the signal to noise ratio is determined by:

obtaining the signal which is an output of a moving average filter of an absolute value of an incoming signal whose absolute value exceeds a pre-determined threshold;

obtaining the noise which is an output of the moving average filter of the incoming signal whose absolute value is below a pre-determined threshold;

dividing the signal by the noise.

14. The system of claim 1, wherein the application program running on the processor provides a user interface to execute one or more functions in a group comprising:

connect and disconnect to the impact detection device;

start and stop the video recording;

review the captured videos;

add comments after reviewing the video;

edit and save snippets of the captured video;

compare videos;

configure parts of the video to be shown in slow motion to allow detailed review of the user action;

edit and save captured still images;

review the captured still images;

compare still images;

configuring the video frame rate;

configuring whether to take the still images in addition to the video;

configuring length of video capture;

configuring plurality of times when the still image is taken.
