“…In a similar way, the EOFM [18] notation is used for evaluation purposes to identify user behaviors that had not been expected. The task models can be updated with the results of these evaluations [22]. Martinie et al [23] enriched the HAMSTER task modeling notation [19] to introduce usability-related concepts, like the complexity or information workload that is associated with a task.…”

A Framework for Identifying Sequences of Interactions That Cause Usability Problems in Collaborative Systems

Collaborative systems support shared spaces, where groups of users exchange interactions. In order to ensure the usability of these systems, an intuitive interactions’ organization and that each user has awareness information to know the activity of others are necessary. Usability laboratories allow evaluators to verify these requirements. However, laboratory usability evaluations can be problematic for reproducing mobile and ubiquitous contexts, as they restrict the place and time in which the user interacts with the system. This paper presents a framework for building software support that it collects human–machine interactions in mobile and ubiquitous contexts and outputs an assessment of the system’s usability. This framework is constructed through learning that is based on neural networks, identifying sequences of interactions related to usability problems when users carry out collaborative activities. The paper includes a case study that puts the framework into action during the development process of a smartphone application that supports collaborative sport betting.

“…Following the PRENTAM process [8] a task analysis was performed to identify task performed with the interactive TV system. Tasks were modelled using HAMSTERS including typical TV related tasks like selecting and changing a channel, changing volume or browsing the electronic program guide (EPG).…”

“…To solve this problem task models and their associated tools can be used, to store and describe the data from the evaluation study, and combine the results from the real time evaluation study with the real time visualizations of the system. Task models bring several benefits when applied in the development process: they support the assessment of effectiveness (as sub-dimension of usability [20]) [10,37], they can support the assessment of task complexity [15,34,41], help in the construction of training material [27] and they support the redesign of the system [8]. Task models that are enhanced with data from user studies can be used as shared artefacts by all the stakeholders of design, development, and evaluation to enable such a connection.…”

Evaluation results focusing on usability and user experience are often difficult to be taken into account during an iterative design process. This is due to the fact that evaluation exploits concrete artefacts (prototype or system) while design and development are based on more abstract descriptions such as task models or software models. As concrete data cannot be represented, evaluation results are just discarded. This paper addresses the problem of discrepancy between abstract view of task models and concrete data produced in evaluations by first, describing the requirements for a task modelling notation:(a) representation of data for each individual participant, (b) representation of aggregated data for one evaluation as well as (c) several evaluations and (d) the need to visualize multi-dimensional data from the evaluation as well as the interactive system gathered during runtime. Second: by showing how the requirements were integrated in a task modelling tool. Using an example from an experimental evaluation possible usages of the tool are demonstrated.

“…The approach of user-centred design often relies on usability testing to improve the quality of the interactive system developed [20]. Usability testing is defined as a testing session of an early prototype or functioning version of a computer interface with representative users attempting representative tasks in a representative environment [21].…”

Cultural and Linguistic Variables in Usability Testing

Canada is a country where more than 1 in 5 are immigrants. While industries and public services in the country interact with a diversity of users, it is unclear if the cultural and linguistic background of their users can influence their perceived usability. We conducted a usability test of the website of Immigration, Refugee and Citizenship Canada to explore cultural and linguistic variables during usability testing, by using cultural dimensions, global English proficiency index and personality test. Our results show that the dimensions of Individualism, Time orientation, Power distance, and Uncertainty avoidance do influence participants' answers. We found that Indian participants were more comfortable with the website's English level while Chinese and Nigerians criticized it more. This thesis concludes that to assure the consistency, reliability and reproducibility of research results and protocols, researchers should recruit participants from multiple cultural and linguistic backgrounds to gather a general ideation of the usability. Since this thesis revolves around cultural and linguistic variables, I decided to thank the people who supported me during the past two years in their first language. J'aimerais avant tout remercier ma superviseure de thèse Dr. Audrey Girouard pour sa patience, sa disponibilité et surtout ses judicieux conseils, qui ont contribué à alimenter ma réflexion. Merci de m'avoir donné l'opportunité de m'introduire dans un milieu qui était tout nouveau pour moi il y a deux ans et de partager tes connaissances et savoir dans le domaine. I would also like to thank everyone I worked with at the Creative Interactions Lab. Thank you for listening, offering me advice, and supporting me through this entire process. You made this experience much more enjoyable than it would've been working alone.
