Combining interconnected wearables provides fascinating opportunities like\naugmenting exergaming with virtual coaches, feedback on the execution of sports\nactivities, or how to improve on them. Breathing rhythm is a particularly\ninteresting physiological dimension since it is easy and unobtrusive to measure\nand gained data provide valuable insights regarding the correct execution of\nmovements, especially when analyzed together with additional movement data in\nreal-time. In this work, we focus on indoor rowing since it is a popular sport\nthat's often done alone without extensive instructions. We compare a visual\nbreathing indication with haptic guidance in order for athletes to maintain a\ncorrect, efficient, and healthy breathing-movement-synchronicity (BMS) while\nworking out. Also, user experience and acceptance of the different modalities\nwere measured. The results show a positive and statistically significant impact\nof purely verbal instructions and purely tactile feedback on BMS and no\nsignificant impact of visual feedback. Interestingly, the subjective ratings\nindicate a strong preference for the visual modality and even an aversion for\nthe haptic feedback, although objectively the performance benefited most from\nusing the latter.\n
