An Interactive Physical-Cognitive Game-Based Training System Using Kinect for Older Adults: Development and Usability...

Area of Science:

• Gerontology
• Rehabilitation Science
• Human-Computer Interaction

Background:

• Declines in physical and cognitive functions increase fall risk in older adults.
• Interactive game-based systems offer a promising approach for simultaneous physical and cognitive exercise, potentially enhancing adherence and reducing fall risk.
• There is a limited number of studies on combined physical-cognitive game-based training systems for fall risk reduction.

Purpose of the Study:

• To develop an interactive physical-cognitive game-based training system for older adults.
• To evaluate the usability and enjoyment of this game-based exercise system.

Main Methods:

• A prototype was developed by integrating expert knowledge and literature on fall prevention exercises.
• Usability testing involved 5 older adults playing 5 different games with varying difficulty levels.
• Participants rated their enjoyment using the Physical Activity Enjoyment Scale (PACES) and provided qualitative feedback.

Main Results:

• The game-based exercise system demonstrated high user enjoyment, with an average PACES score of 123 out of 126.
• Participants provided positive feedback on the well-designed interactions and user-friendly interfaces.
• Specific games included Fruits Hunter, Where Am I?, Whack a Mole, Sky Falls, and Crossing Poison River.

Conclusions:

• The interactive physical-cognitive game-based exercise system shows promise for implementation in older adults.
• The system's usability and high enjoyment suggest potential for engaging older adults in beneficial exercise.
• The effectiveness of this game-based exercise program for fall risk reduction requires further investigation.
