Abstract: In rowing, the proper breathing technique is exhaling on the drive and inhaling on the release. Users who have little to no information about this need some form of feedback to maintain the synchronicity between breathing and rowing. To assist this, we have developed a system analyzing the rowing behavior of the user and providing live feedback through haptic and visual mediums. A study was conducted to test the impact of different feedback modalities on breathing and rowing movement synchronicity. The study involved breathing and rowing movement data collection; then the analysis of the collected data. The statistical test results show that virtual environment itself has no significant influence regarding the synchronicity of breathing. However, haptic feedback is improving breathing synchronicity  over no feedback, while visual feedback alone did not improve synchronicity. In addition to that a significant interaction effect between haptic and visual feedback was found. Further on, the results indicate that the people who have less prior knowledge about breathing techniques in rowing can significantly benefit from instant breathing feedback.
