The Development and Application of a Live Transmitting Head Camera for Video Feedback in Rugby Decision Making

Abstract

Previous studies have explored the use of head cameras in different scenarios, including sport training [1–4]. Until recently, athletes had their practice recorded and such recording was used for feedback purposes. This approach is problematic as it does not allow for immediate feedback and does not provide a similar perspective to those athletes have when training. To overcome this a head camera was developed to record first-person perspective during real-life training situation. This camera consisted of 3 main components: a miniature camera with wide angle lens (140 degrees) and transmitter running on a 2.4GHz frequency with a small helical antenna, a video relay device for increased line of sight between the transmitter and receiver, signal receiver device connected to a laptop computer with video review software. The camera components were mounted within a protective casing and inserted into a custom made rugby soft helmet, commonly known as headgear. The vantage point of the wearer is very different to conventional grandstand camera views and shows that different visual information [5] is presented to an individual making decisions. Case study: A randomised control trial is to be performed consisting of three groups; a group using and viewing footage from the head mounted camera, a group viewing coaches’ perspective, side of field footage and a control group with no video feedback. The players will complete a decision making drill and video feedback will be reviewed with players observing the movements of their teammates and surrounding opponents. Data will be recorded throughout the session measuring which video vantage point is associated with improvements in decision making.
