  1. 1. DEUS Deployment and Ease Use of wireless Services User Experience Introduction – DEUS approach A user-centred design philosophy was followed throughout the DEUS research project. This included several methods for designing, developing and evaluating user-friendly ICT- applications. The first step in this process was to research the generic user requirements for the different application domains. Therefore a user and task analysis was conducted. This analysis takes into account three aspects: the user, his tasks/goals and the context/environment. By observing users in their natural context, these aspects can be studied realistically and in great detail. The goal of this analysis was to gain insight in the way tasks have to be performed, and define a complete set of tasks and subtasks. Analyses were done in a residence for elderly persons (OCMW Gent), in cultural heritage centre Lamot and in art centre De Vooruit. The user and task analysis allowed the researchers to observe people while they configure a wireless network with the current tools and software. Together with the different partners in the project a selection of end- users and situations were chosen. The characteristics of the users and the context are also taken into account, including the user's information need in each context. These results were presented via user requirements, personas (see Figure 1) and scenarios. In a second phase, a conceptual model was developed. This was a translation of the user and task analysis into a specific design and corresponding information structure. The conceptual model described a set of integrated ideas and concepts that explains how the system should look and behave in specific situations. The model is described with a set of activities, interface metaphors and interaction paradigms. In the third phase, storyboards and paper prototypes were developed and tested with end users in order to get feedback on the DEUS solutions’ concepts and user interfaces that were made. This iterative process of evaluation made it possible to identify problems related to usability, usefulness and user experience in an early phase of the project.
  2. 2. DEUS Deployment and Ease Use of wireless Services DEUS solutions All the DEUS solutions are based on the experiences and findings of real life users. The 'end user' was the central figure in the research. The user research was applied in the development of the DEUS solutions as follows: • Knowledge of current use of wireless networks By observing and questioning the end-users that deploy, manage and use the wireless networks in their natural environment, a thorough insight was gained in the ways how wireless networks are configured and what the problems arise. In this way it was possible to ensure that the current way of working was supported by the DEUS solutions, that problems were solved or prevented and that user needs were met. • Generic user requirements A listing of all user requirements for each applications domains was made. Commonalities and specific needs were identified. It was in the interest of all application domains and end-user organizations to maximize the commonalities. In this way a generic solution was created for all application domains. Interaction and discussion with the technology providers ensured the development of future oriented and low cost scenarios. Figure 1 User requirements Vooruit • Representation of users and their problems and needs The user and task analysis resulted in a set of personas (typical characteristics of the users summarized in different profiles). These specific personas were uniquely developed for all scenarios of each use case and were based on the traits and expectations of real end users. In the development of the DEUS solutions, these personas were used to match the iterative versions of the solutions with the end users’ characteristics, problems and needs at all times.

  3. 3. DEUS Deployment and Ease Use of wireless Services • Matching user expectations Each use case was split up into different scenarios, reflecting real life tasks executed by the users that were interviewed. Each scenario proposed by the research consortium was mapped onto the expectations of the end users, resulting from the user research. Doing this made it possible to continuously take these expectations into account during the development of the DEUS solutions. • Development of user interfaces The user interface and general interactions of the DEUS solutions were based on the user requirements derived from the user and task analysis. By continuous assistance of usability experts in the design process, usability issues could be tackled from an early phase onwards. • Low-fidelity prototyping – paper prototyping Storyboards and paper prototypes or low-fidelity prototypes of the different user interfaces were developed for the DEUS solutions. These prototypes made it possible to get feedback about the functionality of the design early in the development lifecycle. The prototypes were iteratively tested by means of formative usability tests with real end-users from the target group in the contexts as specified in the use cases. These low-fidelity prototypes were subsequently used as input for the further technical development. • Iterative formative usability testing The low-fidelity prototypes as well as the further developed versions of the interfaces were iteratively tested by usability experts and real end users. These premature modifications of the product guaranteed the qualitative support of the design process. This way, the prototypes have evolved to models/designs which come closer to the final product. Final testing will be done with the stationary or portable usability lab in the real user context.
