“…Inspection refers to a set of methods that are all based on evaluators feedback about an interface, and includes methods such as heuristic evaluation, cognitive walkthrough, and feature inspection [66]. This method introduced as a more affordable alternative of usability testing, as it does not require participants [67]. Inquiry methods involve user inquiries through interviews or surveys.…”

Model-Based Software Engineering (MBSE) has a high potential to play a critical role in the whole process of software engineering, bringing many benefits to all stakeholders, yet it is not used by most software developers today, due to both lack of tool capabilities and poor user experience (UX) of tools. This study aims to understand the evaluation types and methods applied by researchers when studying UX in modeling tools (modeling experience or MX) and the types of issues uncovered in these studies. We conducted a literature review using a snowballing approach to gather all studies of this topic. A total of 41 research papers were reviewed. Data extraction was performed based on research questions and a categorization of discussed issues was presented. Several gaps and future opportunities were identified and discussed, which include 1) utilizing interview method in research design; 2) distributing testing tasks based on user profiles; 3) involving UX experts in analysis; 4) scalability testing using large models; 5) assessing MX in areas other than just usability and utility; 6) considering collaborative modeling as an important factor contributing to MX; 7) considering both language issues and tool issues in UX evaluation of software modeling tools. 8) improving the taxonomy of MX challenges; 9) triangulating using multiple methods; and 10) developing and validating MX tool design heuristics.

PurposeThis research work aims to arise from developing new communication channels for customer service in micro, small and medium enterprises (MSMEs), such as chatbots. In particular, the results of the usability testing of three chatbots implemented in MSMEs are presented.Design/methodology/approachThe methodology employed includes participants, chatbot development platform, research methodology, software development methodology and usability test to contextualize the study's results.FindingsBased on the results obtained from the System Usability Scale (SUS) and considering the accuracy of the chatbot's responses, it is concluded that the level of satisfaction in using chatbots is high; therefore, if the chatbot is well integrated with the communication systems/channels of the MSMEs, the client receives an excellent, fast and efficient service.Originality/valueThe paper analyzes chatbots for customer service and presents the usability testing results of three chatbots implemented in MSMEs.

“…In particular, the simulator reproduces a lifelike plowing activity, with its details and peculiarity, of a specific tractor, the New Holland model T7, produced by CNH Industrial, in which the user can test the design of the control dashboard of the tractor cabin; taking into account the final scope of the project that is helping developers to produce more usable products. [3] As a result, the outcome of this transdisciplinary process is an improved decision-making capacity of the design team [4], based on the user experience assessment. Following the principles of UX design, the evaluation phase was not only the last of the cycle but went hand in hand with the development of the project.…”

Understanding user experience (UX) is essential to design engaging and attractive products, so nowadays has emerged an increasingly interest in user-centred design approach; in this perspective, digital technologies such as Virtual Reality (VR) and Mixed Reality (MR) could help designers and engineers to create a digital prototype through which the user feedback can be considered during the product design stage. This research aims at creating an interactive Digital Twin (DT) using MR to enable a tractor driving simulation and involve real users to carry out an early UX evaluation, with the scope to validate the design of the control dashboard through a transdisciplinary approach. MR combines virtual simulation with real physical hardware devices which the user can interact with and have control through both visual and tactile feedback. The result is a MR simulator that combines virtual contents and physical controls, capable of reproducing a plowing activity close to reality. The principles of UX design was applied to this research for a continuous and dynamic UX evaluation during the project development.
