Balance training can help stabilize foot joints and prevent injuries. In particular, training programs that use a balance board have shown improved neuromuscular function and reduced susceptibility to injuries. Traditional balance training is often inadequate because there is no feedback, and the "monotonous" movements are perceived as "boring." This paper explores the effectiveness and suitability of an Augmented-Reality enhanced balance board, the HoloBoard. Our application integrates typical ball sports activities such as "catching," "heading," and "dodging," as well as various difficulty levels. We performed an exploratory field study with a semi-professional handball team, which showed that participants preferred the HoloBoard compared to traditional balance board training, enjoyed it, and judged the training as effective.enbalance exercise exergame augmented reality sportsText/Conference Paper10.1145/3603555.3608553
