█ 5.2 Design Suggestions

According to the results of this study, the following design suggestions are proposed to serve as a reference for professional designers to develop VR applications for older adults:

1. Using VR can motivate older adults to exercise. The designers can focus on creating create engaging exercise scenarios to encourage older adults to exercise. This effort can induce users' higher level of attention, entertainment, and time distortion.

2. Though the benefits of VR exercise for physical function in older people remain inconclusive, designers can emphasize providing better VR exercise games to encourage older adults to exercise constantly. The designers can also find ways to overcome this bottleneck through creativity to increase older adults' physical function.

3. Increasing learnability can be the VR design focus for the elderly. Older adults might not receive assistance with adjusting the equipment or operating the VR software in the actual situation. It is recommended to design self-learning courses so that the elderly can gradually become familiar with the operation of VR without time pressure. During the VR exercise, more prompts and guidelines are encouraged to provide to guide the older adults.

4. The ease of use for VR equipment should be improved to increase the users' learnability. For example, the complex calibration or setup procedure can be simplified in the future. Furthermore, VR devices are becoming increasingly prevalent amidst perpetual component miniaturization and cost reduction. The designers are expected to provide solutions to reduce the difficulty of learning VR equipment.

5. According to the interview, participants reported a lack of resemblance between the VR controllers with real dumbbells. Designers can consider developing a customized VR controller that resembles actual dumbbells of their physical shape, weight, and hand-held operation.

6. Some older adults report dizziness problems. It is recommended that movement design for VR exercises should avoid users' continuous body moving. The design of steady and periodic rest for older adults can reduce dizziness.
