Development and qualitative assessment of the GAME(Cycle) exercise system

Area of Science:

• Rehabilitation Engineering
• Exercise Physiology
• Human-Computer Interaction

Background:

• Physical activity is crucial for cardiovascular health, yet inactivity is common among individuals with disabilities.
• Existing exercise solutions may not adequately engage this population.
• The GAME(Cycle) was developed to address this gap by integrating arm ergometry with interactive video gaming.

Purpose of the Study:

• To document the algorithms underpinning the initial GAME(Cycle) device.
• To introduce and evaluate novel features in the second-generation GAME(Cycle).
• To gather user feedback from clinicians and wheelchair users on the system's usability and potential for promoting exercise.

Main Methods:

• Detailed description of the algorithms controlling the GAME(Cycle) based on arm ergometer input (angular velocity and swivel rotation).
• Introduction of new features: wheel on base, steering return mechanism, and wireless fire buttons.
• Conducting a focus group with clinicians, wheelchair users, and clinician wheelchair users (total n=12) to assess the enhanced GAME(Cycle).

Main Results:

• The focus group provided valuable feedback, suggesting specific improvements for the steering mechanism and vibration reduction.
• Participants generally enjoyed the GAME(Cycle) experience.
• The consensus was that the GAME(Cycle) holds significant potential for encouraging physical activity in individuals with disabilities.

Conclusions:

• The second-generation GAME(Cycle) incorporates user-driven enhancements to improve the exercise experience.
• Despite minor suggested improvements, the system is perceived as a promising tool for increasing exercise adherence among people with disabilities.
• Further development based on user feedback can optimize the GAME(Cycle) for broader adoption and impact on cardiovascular health.
