This study investigates aspects of the role gender plays in participatory design innovation workshops; reflecting on both the process and the output. Often when gender and design are discussed, the problems raised concern a lack of women as designers or developers [26], but there appear to be gaps in addressing full gender representation when it comes to users in the design process. In this study, a design workshop was run where participants, two men and five women were asked initially to identify or generate problems and possible digital solutions concerning their academic studies, and then to design their top self-selected solution. The workshop was recorded and transcribed, and conversation and discourse analysis were carried out which found gender to influence problem raising, language used and group practices. The paper concludes both that gender apparently plays a strong role in group dynamics with regards to design innovation; and that thematic conversation and discourse analysis provides an appropriate and insightful approach to understanding these issues.

Avatar-mediated communication in virtual reality (VR) is challenging when compared to face-to-face communication, particularly, for expressing users’ intentions to others. This is due, in part, to the technological medium’s restriction of nonverbal communication cues, including gesture and facial expression. In platforms for social VR, there are interfaces that allow users to express their intentions through their avatars by selecting several given symbolic gestures, e.g., ”good” and ”surprise”. However, little is known about the effects of the symbolic gestures on communication. We investigate the effects of symbolic gestures on communication in VR and conducted user experiment with brainstorming tasks in three different conditions: VR with symbolic gestures, VR without symbolic gestures, and face-to-face. Our results showed significant differences in several items of the participants’ subjective questionnaires, i.e., participants reported that symbolic gestures helped them to express their intentions and feelings more easily than the other conditions. It means symbolic gestures improve social presence on communication in VR.

Parental engagement in their children’s education is known to be an important predictor of children’s academic success. However, adults with less education (ALEs) in developing countries face several challenges in supporting their children at home, particularly after the children reach middle school. This research aims to facilitate parental engagement through an intervention in the Indian context. We first conducted user studies with 113 ALE parents to understand the dynamics of parental engagement. We learned that though many ALE parents invest heavily from their limited resources so that they can send their children to paid tuition classes, otherwise they lack time, resources and self-efficacy to get better engaged with their children’s education. Based on these insights, and with the help of a school teacher, we came up with four hyper-local video prototypes - we call these “explainer video”, “guider video”, “discussion video” and “homework video”. We sent these videos over WhatsApp to 12 ALE parents in Pune, India and followed up with them for two weeks. We found that parents of “better-performing” students perceived the videos to be useful and tended to watch more videos whereas parents of “not-so-well-performing” students required additional mediation and triggers. An important learning was that interventions need to help parents and children develop an academic culture at home. Overall, these videos made parents aware about their children’s educational activities and helped them get better engaged with their education.

As refugees attempt to develop a sense of normality during times of crisis, digital spaces have proven themselves to be valuable sources of information and connection. Drawing upon the ‘new normal’ theory, this paper aims to better understand how refugees use these spaces and how they encourage a sense of normality. A qualitative analysis of 171 social media posts reveal that refuges sought advice, shared their stories and clarified myths and misunderstandings around refugee lives, while non-refugees offered to help during the times of crisis. These findings contribute to the HCI research by offering to showcase the ways in which such forums are used by refugees, what this reveals about the values and experiences of refugees and how this intersects with the broader community.

Research in HCI and CSCW has consistently shown how software design approaches are an abstract idealisation of work practices, raising questions regarding the appropriateness and applicability of what might be considered as ‘best practice’ or ‘doable practice’ in project work. Such issues have magnified the fundamental need for examining exactly how conventional (and generally Western) constructs, approaches and methods, widely adopted in the process of producing and deploying technologies, actually work. The paper reports findings from a study that seeks to understand the implications for adopting ‘well-known’ practices for framing, undertaking, and analysis distributed and collaborative software project in the context of Nigeria. Findings show that documenting and analysing what is often considered as ‘best practice’, supposedly prescriptive maps and scripts for accomplishing work, necessitates considering how they get adopted, interpreted, and extended as ‘orderly’ and occasionally ‘messy’ alternatives, offering some sensitivities for understanding the translocal features and transitional meaning of agile project work.

Studies of smart speakers highlight issues people face with understanding why unexpected behaviour occurs and with recovering from mistakes due to uninformative responses. Yet, our understanding of such intelligibility issues in smart speakers — difficulties in understanding the device's behaviour — remains limited, in particular, for long-term and frequent smart speaker users who may encounter more complex situations than first-time users. We conducted an online survey and interviews with smart speaker enthusiasts to investigate how they form an understanding of the device's behaviour and what strategies they use to recover from breakdowns. We identified seven different breakdown recovery strategies and found that enthusiasts particularly struggled with breakdowns in their IoT infrastructure. Informed by our results, we propose three research directions: infrastructural breakdowns as learning opportunities for understanding the smart speaker's behaviour; leveraging aspects of non-verbal communication as opportunities for design; and considering passive users’ intelligibility and control needs.

We designed and trialled a virtual reality application, Melbourne 2100, that simulates a flooded CBD in a future Melbourne impacted by climate change. We hypothesised that experiencing dystopian futures in VR can make abstract and distal climate change more concrete for people, provoking public engagement and discussion. This paper presents the first stage of a project to design and trial our system with members of the public. We describe our design process, the application we built, and the results of a user study. Observations and interviews yielded feedback that will inform the ongoing development both the application and our methods for gauging its impact. The study indicates that VR is a viable medium for engaging the public with the critical issue of climate change.

In this study, we extend Fitts’ law to enable it to predict the movement time of pointing operations in interfaces, such as those in navigation bars whose items have different clickable and visual widths and intervals between a target and distractors. For this, we conduct two experiments to investigate the effects of distractors on pointing operations and how increasing the interval size changes user performance. We find that the movement time is significantly affected by the clickable width and intervals whereas it is only slightly affected by the visual width. Based on the results, we construct a time prediction model for considering the differences between clickable and visual widths and the intervals between a target and distractors. Our model shows a good fit for not only the data of our two experiments but also for those of three previous studies.

While VR has shown benefits such as improving alertness, recalling memories and cognitive training for older adults, it is challenging to deploy it in aged care settings due to the complexity of social care, physical and healthcare needs of the residents. This paper presents a two-phase study that aims to explore the challenges of deploying VR technology in aged care settings. Phase one involved a thematic analysis of video recordings of 14 VR sessions, during which five residents of an aged care facility were invited to experience and interact with VR systems. Phase two aimed to explore the challenges further by analyzing semi-structured interviews with 11 staff members who had experience in coordinating VR activities in aged care homes. The results revealed a range of issues that need to be considered when deploying VR systems in aged care settings, including: usability issues related to VR systems; barriers caused by residents’ mobility constraints; physical discomfort; and challenges in providing guidance and support for residents using VR.

Storytelling is an effective approach that is used in interaction design to help align users’ needs throughout the design process. In this paper, we utilize a storytelling approach with hands-on design toolkit activities to investigate how the experimental order effect can have an impact on the overall outcomes. In particular, we focus on a robotic design toolkit that aims to involve children in the process of designing assistant classroom robotic artifacts. We report the findings of a study conducted with 28 children that designed their own classroom robotic assistance using the toolkit before and after storytelling. We conclude the paper with discussion on the order effect and design findings. This paper aims to contribute to the literature with insights on how to implement storytelling along with a prototyping toolkit; approaches that are highly valued in interaction design research and practice recently.
