Sonic Trampoline: How Audio Feedback Impacts the User´s Experience of Jumping

To investigate how auditory augmentation influences user jumping activity on an elastic trampoline, the authors developed a system to interactively augment the trampoline´s sound. The system´s sound design is inspired by iconic jumping sounds from games, with sensing technology based on a combination of motion tracking with depth camera and audio-based contact sensing between the feet and trampoline. Results show that such interactive sonification stimulates changes in the user´s behavior toward increased performance during the exercise; it also positively affects the user experience.
