We provided the Usability Lab of the TU Berlin with a Haptic Breathing Belt prototype to investigate how haptic feedback can improve effectiveness and efficiency in learning how to row.
The Belt sends Vibrotactile Feedback to the rower and thereby teaches subconsciously to incorporate a stable breathing pattern while moving.
For optimal movement and breathing coordination, the Breathing Belt was used in conjunction with a Virtual Reality Headset.
By using this setup the overall performance of novice rowers could be improved significantly.
Robert Greinacher documented this process and the results in his paper: Impact of Tactile and Visual Feedback on Breathing
Rhythm and User Experience in VR Exergaming.
