“…Such a standardized definition can enable goals and measurements to be unified in the domain of service experience but is missing in the context of WFH. Some researchers (Bentley et al, 2016;Rajanen & Rajanen, 2020) have suggested that people's experience of complex sociotechnical systems is usually determined by a subjective reaction to objective aspects and constraints. Therefore, it seems plausible that the interplay between a subjective reaction and objective aspects is a determinant in the quality experienced by people in WFH modalities.…”

Introduction: Working from home (WFH) remotely is a modality of working that requires the careful design of systems of rules and tools to enable people to exchange information and perform actions. WFH is expected to expand after the COVID-19 pandemic, and how best to reliably assess and compare the experience of workers with different (sociotechnical) systems of WFH is central to the diffusion of acceptable modalities of remote working. However, the concept of experience and how it can be measured in the domain in WFH is yet to be clearly characterized.Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology for scoping reviews, we systematically map the approaches used by researchers to assess WFH, identify which aspects are usually investigated, and examine how such aspects are usually measured in terms of questions and tools. Literature is collected using Scopus and Web of Science.Results: Thirty-four records out of 323 focusing either on validating a scale, presenting theoretically the experience of workers or testing this empirically are included in the qualitative synthesis. The results highlight a lack of unified terminology and tools, with assessments of workers’ experience mainly characterized by survey approaches and qualitative questions. Conclusion: Clustering together the most investigated aspects in the literature and reviewing how these aspects are assessed, we propose a list of 10 relevant overarching dimensions and attempt to define workers’ experience in the domain of WFH remotely. This definition can be used as a tool by researchers aiming to assess the experience of workers in order to inform the design or redesign of the sociotechnical systems that enable WFH.

“…However, traditional HCI that involves users in system design can offer a limited viewpoint for the broad and global transformations that occur in society. Contemporary technology and information systems not only influence end users but also have holistic effects on society at large (Rajanen & Rajanen, 2019).…”

“…Researchers have begun to refine key UX and usability concepts to fit the information technology in the age of collaboration and sharing (Abhari, Davidson, & Xiao, 2019). Usability represents a core concept in socio-technical system development because it impacts how users and society perceive and experience technology-driven transformations, and it acts as a mirror of the world or speculum mundi (Rajanen & Rajanen, 2019). This special issue contributes to the emerging body of knowledge on HCI in a sharing society.…”

“…Usability, an established construct in HCI, addresses how users interact and perceive an interactive system, product, or service, and both designers and users consider it a multidimensional, multifaceted issue. One can see the usability of the systems that exist in the world as mirroring technological advances, a speculum mundi (Rajanen & Rajanen, 2019). Thus, one needs to consider usability in designing and developing socio-technical systems.…”

In this editorial, we introduce a special issue in AIS Transactions on Human-Computer Interaction (THCI) on humancomputer interaction in the sharing society. We introduce the history, motivation, and key concepts behind the issue and briefly overview the four papers in the issue. We argue that a traditional "narrow" view of HCI fails to provide sufficient designs in the emerging sharing society contexts for several reasons. We briefly introduce key concepts for the sharing society, sharing economy, and collaborative economy. Subsequently, we introduce HCI in a sharing society as a call for new socio-technical HCI design approaches and new HCI tools and designs for a sharing and sustainable society. We also introduce four interesting socio-technical HCI papers in this issue. We conclude by restating the importance of HCI concepts together with the need that HCI researchers and practitioners adopt and advance a broader perspective of their work and designs to include societal, environmental, and professional concerns.

“…Conceptually, and from a theoretical perspective, usability concerns the rich interaction of users and technology in a socio-technical context [ 13 ]. Usability may even be viewed as part of the higher-level concept of interaction experience, together with user experience (including aesthetics, trust, value, affect) and accessibility [ 14 ].…”

Usability Evaluation of Slanted Computer Mice

Prevention of musculoskeletal disorders is supported by use of slanted rather than horizontal pointing devices, but user acceptance of the former may be compromised due to lower perceived ease of use. This study compares subjectively rated usability (N = 37) for three sizes of slanted computer mice and includes a horizontal small conventional device as a reference. For a random subset of the sample (n = 10), objective usability parameters were also elicited. Participants followed a standard protocol which is based on executing graphical pointing, steering, and dragging tasks generated by a purpose-built software. Subjective ratings were collected for each of the four pointing devices tested. The three slanted devices differed in size but were chosen because of an approximately similar slant angle (around 50–60 degrees relative to the horizontal plane). Additionally, effectiveness and efficiency were objectively calculated based on data recorded for the graphical tasks’ software for a random subset of the participants (n = 10). The results unveil small differences in preference in some of the subjective usability parameters across hand size groups. This notwithstanding, the objective efficiency results are aligned with the subjective results, indicating consistency with the hypothesis that smaller slanted devices relative to the user’s hand size are easier to use than larger ones. Mean values of weighted efficiency recorded in the study range from 68% to 75%, with differences across devices coherent with preference rank orders.
