Using sensors to augment sports equipment offers the possibility of accurate and transparent judging. Ensuring acceptance and adoption of such technology is complicated, however. To succeed, technological developments in sports equipment must not only be accurate and relatively nonintrusive, but must also account for social acceptance issues, including the players' perception of fairness and rule changes. In this article, the author discusses these issues in relation to sensor technology application in an unforgiving environment: the martial arts sparring ring. The SensorHogu system uses piezoelectric force sensors in body protectors to help taekwondo judges score real tournament matches. The author describes the development team's experience with introducing the technology and also discusses the evaluation of it and other similar sports technologies using an evaluation framework developed for ubiquitous computing applications. This article is part of a special issue on pervasive computing in sports.
