6. Conclusions

Successful ageing is based on three components: limited disease-associated disability, high cognitive and physical function, and continued engagement with life.

Staying physically active in older age is a key factor in achieving the three components of successful ageing.

Smart wearable devices that track physical activity can improve seniors’ fitness level and increase their motivation and engagement to remain physically active.

Lack of technological skills could be the greatest barrier in adopting a smart wearable device for seniors.
