“…They are a synthesis of several people who share the same objectives, motivations and behaviors. A Persona is then defined in two parts: first a list of characteristics and then a narrative about the character [15]. Following [14] and [16], several authors, such as [17-21 have proposed various techniques to identify Personas but the Persona principle remains the same: to define one or more archetypes of users through the description of psychological components, objectives, motivations and behaviors.…”

Abstract-This paper aims to present an experience report on a new pedagogical technique which applies to the teaching of interactive systems: the Living Persona technique. First, we review the well-known technique of Persona that is used in some processes of realization of interactive systems. In this technique, a Persona represents an archetype of the users interacting in the system to be produced. From this Persona technique, we define the Living Persona one. Within the framework of practical work students have to specify an interactive system, this technique of Living Persona consists in making the teacher play the role of a representative of the contracting authority, who is also potentially a future user of the system to be specified. As a consequence, during his meetings with the students, the teacher has to adopt a behavior in compliance with the state of mind of the users' archetype defined by the Persona. Then we present a pedagogical scenario which integrates this Living Persona technique and we apply it to a practical work in which the students must produce an interactive system specification using the Unified Modeling Language (UML). We show through a classroom experience that the practical work set up provides students with work situations close to professional realities. We evaluate the level of interactions between students and teacher and the extent to which this pedagogy influences some students behaviors. Finally, the continuation of our research is highlighted.

“…According to Sproll et al [1], as the field of User Experience (UX) explores these needs and their fulfillment, it gains in importance against the background of the wish for human-oriented products and services. In order to develop usable systems is necessary to understand the users that will interact with the system [2].…”

“…It is also difficult to verify if a persona really reflects user"s data [5]. The Persona technique is used in order to aid designers to create empathy with the users and identify users" characteristics [2]. Empathy has been employed as a defining characteristic of designer-user relationships when design is concerned with user experience entails [6].…”

Abstract-A software product's acceptance depends on the user experience that it provides to its users. The software product must meet the user needs, and one way to understand those needs is through creation of Personas. The Personas technique allows describing the users' characteristics, goals and skills. The Empathy Map (EM) method can be used to describe personas. The EM's goal is to create a degree of empathy with the user so the product developing team starts to understand more deeply the users and become more aware of their real needs. To assess the EM effects on the creation of personas, we conducted a feasibility study with 20 subjects. Initially, the subjects learned how to describe personas in textual form. After that, they applied the EM to create personas. After using the EM, the subjects answered a questionnaire about their perceptions regarding the EM's ease of use and its usefulness. The results showed that majority of subjects considered EM useful and easy to create personas. Furthermore, this majority also said that they would use the EM for the creation of personas again.

“…Among various methodologies on user requirement analysis, a scenario-based approach (e.g., scenario-based design, 842 Downloaded by [UQ Library] at 07:00 13 June 2015 personas) can be utilized for unusual products because of its convenience and adaptability (Acuna, Castro, & Juristo, 2012). Scenario-based design is an approach that provides clear, welldefined inputs toward system requirements.…”

“…This method further provides a platform for designers to extract core qualities or issues, which can then be examined in a more quantitative, rigorous manner (Carroll, 2000;Carroll & Rosson, 1992). However, for the case of special users and an unusual system, scenario-based design is potentially ineffective due to uncertainty (Acuna et al, 2012;Cooper et al, 2007;Lee, Suh, Kim, Park, & Yun, 2010). It is exceedingly challenging to predict user behaviors due to limited information and experience about a specific type of special user.…”

As tactual information processing of visually impaired users has not been investigated sufficiently and there are few guidelines on the development of haptic user interfaces, development of haptic assistive system can pose many challenges. Despite the breadth and variety of tools available for elicitation of user requirements, no single tool adequately provides the needed information to develop such a specialized system for a unique user population where the understanding of user behaviors is limited. This article explores the state-of-art of requirements engineering, discusses the challenges in developing a haptic assistive system, and proposes a methodology of combining a controlled observation in a naturalistic setting with scenario-based design for effective and efficient user requirements elicitation. A case study of developing a haptically enhanced, collaborative learning-by-feeling science education system for visually impaired students was conducted to show validity and effectiveness of the proposed methodology. The case study showed that the methodology has a variety of benefits including the reduced uncertainty and a better fit to the natural behaviors of the user population.
