“…Over the years, thanks to further developments, the Walkthrough method has been integrated to analyze the users' point of view and to evaluate the usability of software applications; therefore, it is configured as an analytical analysis tool that can combine analyses carried out across digital platforms (Katz, 2020) with classic qualitative techniques such as: interviews, for example to analyze how, in the context of global migration, the use of digital media can maintain transnational connections or to analyze the governance of different Apps and compare them (Li, 2020); focus groups, to evaluate the implementation of new Apps through the users' experiential system (Wardhani et al,2019); content analysis, to analyze the terms of service and privacy policies and establish measures for the collection, storage, transfer, use and disclosure of App data (Heemsbergen & Molnar, 2020); critical analysis of the discourse, to analyze the digital intermediation of connectivity services (Cabalquinto & Wood-Bradley, 2020); participant observation, to carry out comparative analyses on the phenomenon of platformization (Nieborg, Duffy & Poell, 2020). Anyway, the approach that developed the most is the one of usability evaluation: the Human-Computer Interaction (HCI) implies an iterative process in which evaluation is fundamental to inspect the usability of the user interface.…”
