User demographics, perceptions, and motivation data obtained from actual observation and experience surveys provide contextualized and first-hand information for game designers. However, this type of information can be misinterpreted if it is presented as numbers. Contextual Design (CD) is a user-centered method that allows a better understanding of the user’s work environment, as well as the requirements that the interactive systems must have to cover their needs. According to the CD, the user Personas (also called archetypes) are representations of users created to establish behaviors, likes and motivations of a representative group of users who share common patterns. These types of profiles can represent user groups during the design and development process of a videogame, thus allowing a more focused design. This paper describes step by step the process of designing user Personas for a group of 25 participants with stroke. This information was obtained from contextual interviews and gaming experience surveys, which allowed a more homogeneous interpretation of the dislikes, limitations and motivations of the participants. The CD methodology showed to be very useful, generating four user profiles, which were used for the creation of a serious video game in virtual reality that allows therapeutic support in a physical rehabilitation process for people with stroke. Finally, this work presents the preliminary design of the videogame and the importance of the information in the creation of user models. [ABSTRACT FROM AUTHOR]
