The HEXAD gamification user types are attempting a segmentation of users based on their receptivity to varying gamification strategies. The underlying model is based on research on human motivation, player types, and years of practical design experiences. This model presents the first typology to classify users of gamified systems, enabling clustering them based on intrinsic and extrinsic motivational factors. The HEXAD model is comprised of the following six gamification user types: Socializers, Free Spirits, Achievers, Philanthropists, Players, and Disruptors. We have developed a questionnaire to assess how a user is represented by the different gamification user types. The following paper will present the development process of the questionnaire. Application venues will be discussed.
