The percentage of the elderly population is increasing in India and around the world. To avoid potential pressure on medical facilities in the future, it is essential to do preventive interventions in elderly care. One way is to encourage them to be more physically active. One design intervention that can help them make this mundane task more enjoyable is creating fun and motivating physical activities. In this project, we look forward to designing gameful walking activities for seniors with existing health and fitness technologies. We aim our design at older adults 65+ years of age who can walk around independently and do not require special supervision. We aimed to make walking, a form of moderate-intensity activity, fun and engaging for them. Our research found that older adults have a significant interest in religion and spirituality. In this project, we limit our scope to the Hindu religion and focus on the context of pilgrimages in India. In many of these places, people have to walk a long distance and have multiple mythologically significant spots on the way or around it. We took that context and made a fun smartphone application-based activity around it. Older adults can play it in a group or individually. It is called 'Gaman'. In Hindi, it means ‘going’ or ‘travelling.’ The pilot evaluation showed that older adults found it fun and said it could effectively motivate people and would like to do this activity again.
