Stroke is one of the leading causes of death and disability. Rehabilitation plays important role in stroke therapy. Digital games show promise in helping stroke patients recover from movements of the impaired upper and lower limbs. However, most of the digital games available in the market are not well-designed for stroke patients. In this study, we aimed at investigating and understanding needs of stroke patients by applying User-Centered Design (UCD) methodology that consists of understanding users, analysis of data, design and development, and evaluation. We conducted user interview sessions with 20 stroke patients and 8 occupational therapists followed by observational studies. Based on the findings from the user study, we developed three different personas: motivated patient, demotivated patient, and friendly therapist. These personas highlight specific problems and needs of different user groups. We explored important users’ needs and design inputs or design opportunities from three different personas for different user groups. These design opportunities reflect the real needs of specific users and help the designers user-centered in designing a system or a digital game for rehabilitation. In conclusion, personas are useful and insightful for designers in designing a particular system for specific user group.
