Chronic illness are conditions that last for a long period of time, and these illnesses require a substantial amount of medical treatment and attention from the hospitals and carers. Unfortunately the limited health resources in hospitals often result in patients receiving substandard treatment, and were often sent off with self-manage their condition. Studies have shown that patients who received little to no support are more likely to struggle with managing their condition, which often results in avoidable complications. This thesis aims to implement a mobile application, targeted towards people with traumatic brain injury and depression, by exploring different memory and social systems and data visualization techniques.
