Keep On Keep Up (KOKU) is a serious game designed to promote strength and balance exercises for seniors in a fun and interactive way. Strength and balance exercises can reduce the risk of falling substantially, but without the intervention of a therapist the degree of physical exercise tends to be low. This gamified app stimulates seniors to do exercises and play games independently in order to stay fi t and hydrated and retain strong bones. KOKU aims to equip older generations and enable them to take control of their health by improving access to, acceptance of and involvement in fall prevention exercises as well as awareness of practices that facilitate a healthy old age. This makes seniors less dependent on social services and healthcare and helps avoid fall-related injury and associated costs.
