Iterative User Experience Evaluation of a User Interface for the Unification of TV Contents

Evaluating 2D and 3D serious games: The significance of student-player characteristics

“…Accordingly, experience design goes beyond user-centered design, as it puts more emphasis on the quality of the users' experience (Lallemand, Gronier, & Koenig, 2015). UX assessment includes user-based and expert-based evaluation using qualitative as well as quantitative methods such as physiological measurements, self-reported measures, usability tests, expert evaluation, heuristics, cognitive walkthroughs and guidelines reviews (Almeida et al, 2018;Bernhaupt & Mueller, 2016). Moreover, during the design of educational material, it is necessary to take into account the specific characteristics of the people to whom it is addressed and the context in which it will be applied.…”

The TV Ecosystem is Fragmented and in Need of New Business and Technological Strategies

“…Throughout subsequent cycles of IDEATION, PROTOTYPING, and TESTING, typical of a DT methodology, several versions of the UltraTV prototype, were created and evaluated. The approaches and the diferent outcomes of the research are detailed in [1,6,7,16,21,58,62]. For instance, the frst major prototype was evaluated following an expert review methodology [6] and provided the initial validation for the unifcation concept, with some recommendations for improvements.…”

“…The approaches and the diferent outcomes of the research are detailed in [1,6,7,16,21,58,62]. For instance, the frst major prototype was evaluated following an expert review methodology [6] and provided the initial validation for the unifcation concept, with some recommendations for improvements. Additional major versions were tested following a triangulation of standardized surveys, SUS [14], SAM [12], and AttrakDif [27], complemented by qualitative data, an approach previously used with success in similar scenarios [2,4,11].…”

“…The quantitative facet of the standardized surveys had the advantage of allowing easier comparisons over time and across diferent versions of the prototype. Based on this evaluation model, there was a TEST cycle performed in the laboratory, complemented with a characterization questionnaire and a semi-structured interview [7]. A fnal evaluation cycle was performed after almost one month of a feld trial, where the standardized surveys, were complemented by a characterization questionnaire, an online survey targeting specifc unifcation concepts, and a fnal telephone interview [62].…”

An iTV Prototype for Content Unification

“…Throughout these stages, assessments of the UI design, usability and overall User Experience were made. Following the internal validations of first sketches and low fidelity mock-ups, the research team adopted an evaluation methodology that included a review by experts [1,4], a UX lab testing phase [2] and a month-long field trial with end-users [5]. The assessment was made using several UX evaluation methods and metrics and interviews.…”
