As per an article posted in teamusa.org, The 2014 U.S. Open has been selected as one of two WTF-sanctioned Open events to perform a field test using the new Daedo Electronic Headgear.
The Daedo Electronic Headgear will be used for two junior weight categories over a two-day period.
The data collected will be used to provide the WTF with data that will be used to determine whether the Electronic Headgear will be confirmed for use at future WTF-sanctioned events. The Trelleborg Open and the U.S. Open have been selected as the events to conduct these field tests.
Once again, the U.S. is at the forefront of the development of technology in the world of taekwondo.
