06/01/2015 - End of the JUDOCARE project. The JUDOCARE project has officially ended. No development will be done anymore, and there will be no further releases. This project was made possible through the generosity of the AppliedERP Corporation. It was a method of providing economical and non-proprietary computer aided replay system for judo arbitration use. This site was maintained by Daniel Lee. He is an IBM, Peoplesoft/Oracle alum, and he is a head instructor at Irvine Judo Club in California, USA. He donates his time as a referee and coach at judo tournaments. He’s been sharing these step-by-step instructions with tournament directors, coaches and referees around the world.
What is the Judo CARE?
JudoCARE is COMPUTER AIDED REPLAY (CARE). This video tool is used in judo referee arbitration. It is widely accepted in elite national and international point tournaments in continents of Asia, Europe, N.America, S.America, India, Africa and Australia.
The JudoCARE system is created for tournament directors, referees, and coaches, but mostly for the players. It is a video tool to help make sure the right player gets the win. It is possible for a referee’s single decision to impact the whole match's outcome; further more the player's career. Through this internal improvement we can attract and retain more athletes, coaches, referees, spectators and sponsors to judo.
The previous generation CARE was based on WinTV software solution with propriety converters. It was a great system, but the cost of replacement parts was prohibitive. The second generation CARE was a brain child of Bruce Larkins. It consists of a laptop and a camcorder linked via analog-to-USB dongle. The current generation of CARE system is in its third evolution. It consists of a laptop and a couple of high definition webcams and sports analytics software and a specialty video player. The benefits are affordability, ubiquitous off-the-shelf parts, and ease to use. It has been conceived at appliederp lab, pilot tested at nanka (SoCal) and Texas tournaments, and field tested at USA Judo point tournaments.
The new CARE will provide innovative referee training opportunities resulting in improved referee performance during tournaments. Judicial use of CARE will lead to a better image of referees among players, coaches, and spectators. We may someday achieve referee professionalization. Through this project, I aim to establish a revolutionary CARE based training center. It will use state-of-the art digital technologies for reviewing actual judo situations to support education and further training and development of referees. The suggested methods will enable us to achieve higher accuracy of decision-making, and improve the fairness of matches. The CARE based training will prevent speculations and guesses concerning the appreciation of a technique. It will be useful to coaches, referees, and most importantly the players. All in all, judo wins.
Operation by CARE consultants:
Operation by CARE referees:
The responsibility of on-site setup, and troubleshooting resides with the tournament director/chief referee. Under this plan, the CARE system will be bought, stored, configured, delivered, and installed by tournament director. The tournament director with help of Chief Referee will insure sufficient number of CARE referees are present to operate care.
A training center will provide opportunity for everybody (players, coaches, journalists, general public, or referee prospects) to try out the actual job of a referee at various venues. This website contains every information necessary for self-study. Please take advantage of it. If you need more training, professional training can be provided by CARE consultants. The consultants will travel to your site and conduct a day training session. This is a for-fee consulting service. However, there will be training opportunities provided by CARE referees at some tournaments pending the trainer's availability. The training opportunity will be announced during the referee meeting, if available. Additional help/training is available via this website's help forum.
It's an economical one camera system suitable for local tournaments. Because there is only one cam, the laptop does not need to be powerful. The photo shows my daughter's 6 years old laptop and equally old webcam on a desktop tripod. I commandeer this setup for local tournaments.
When the stakes are higher, use 4 cameras from east, west, south, north angles.
IJF uses two live camera operators from top and bottom of the mat.
