Paper Abstract:
|
Regular strength exercise training is recommended by the WHO. Users especially novices or patients call for
intensive supervision to execute strength exercises correctly even if performed with a fitness device. Usually, a trainer
or a physiotherapist provide guidance and assist the user. However, increasing costs and missing experts call for new
solutions that support the user to perform strength exercises correctly and without supervision of an expert.
This paper describes the fitness system SMART-FIT. The system comprises a cable machine, a notebook, and a tablet PC
providing visual feedback during strength exercise training. 36 participants volunteered in our user study, designed as
within-subject experiment. Performing a shoulder exercise, participants tested 3 different visual feedback interfaces:
2-Pillar, 1-Pillar, and Ribbon. We evaluated the effect of the interfaces on the performance, e.g., Pearsons correlation
coefficient. Additionally, we applied the questionnaires Flow-Short-Scale, NASA-TLX, AttrakDiff2, and System
Usability Scale among others. The results of our user study will enable designers to make more appropriate design
choices for future exercise support systems. |
