Cryptographic tools for authenticating the provenance of web-based information are a promising approach to increasing trust in online news and information. However, making these tools’ technical assurances sufficiently usable for news consumers is essential to realizing their potential. We conduct an online study with 160 participants to investigate how the presentation (visual vs. textual) and location (on a news article page or a third-party site) of the provenance information affects news consumers’ perception of the content’s credibility and trustworthiness, as well as the usability of the tool itself. We find that although the visual presentation of provenance information is more challenging to adopt than its text-based counterpart, this approach leads its users to put more faith in the credibility and trustworthiness of digital news, especially when situated internally to the news article.

Online harassment against women - particularly in gaming and virtual worlds contexts - remains a salient and pervasive issue, and arguably reflects the systems of offline structural oppression to control women's bodies and rights in today's world. Harassment in social Virtual Reality (VR) is also a growing new frontier of research in HCI and CSCW, particularly focusing on marginalized users such as women. Based on interviews with 31 women users of social VR, our findings present women's experiences of harassment risks in social VR as compared to harassment targeting women in pre-existing, on-screen online gaming and virtual worlds, along with strategies women employ to manage harassment in social VR with varying degrees of success. This study contributes to the growing body of literature on harassment in social VR by highlighting how women's marginalization online and offline impact their perceptions of and strategies to mitigate harassment in this unique space. It also provides a critical reflection on women's mitigation strategies and proposes important implications to rethink social VR design to better prevent harassment against women and other marginalized communities in the future metaverse.

The contemporary understanding of gender continues to highlight the complexity and variety of gender identities beyond a binary dichotomy regarding one’s biological sex assigned at birth. The emergence and popularity of various online social spaces also makes the digital presentation of gender even more sophisticated. In this paper, we use non-cisgender as an umbrella term to describe diverse gender identities that do not match people’s sex assigned at birth, including Transgender, Genderfluid, and Non-binary. We especially explore non-cisgender individuals’ identity practices and their challenges in novel social Virtual Reality (VR) spaces where they can present, express, and experiment their identity in ways that traditional online social spaces cannot provide. We provide one of the first empirical evidence of how social VR platforms may introduce new and novel phenomena and practices of approaching diverse gender identities online. We also contribute to re-conceptualizing technology-supported identity practices by highlighting the role of (re)discovering the physical body online and informing the design of the emerging metaverse for supporting diverse gender identities in the future.

In virtual reality (VR), Impossible Spaces allow rooms to overlap each other in physical space, enabling developers to better utilize the limited space available for VR systems. Prior work has explored detect thresholds for an impossible spaces, but little work has considered how impossible spaces affect users’ understandings of spatial relationships within virtual environments. We present a study evaluating how impossible spaces affected participants’ judgments of a room’s width, and how this was impacted by whether participants considered each room individually, or within the context of the entire space. Participants’ judgments of single rooms was not impacted by being in an impossible space, however judgments were significantly smaller when considering an impossible space as a whole. Even so, participants’ judgments preserved the respective ratio between overlapping rooms, indicating that the relative sizes of different rooms is preserved in impossible spaces. This suggests that while absolute spatial information may be disrupted by impossible spaces, important relative information can be preserved. However, it is not yet clear how much of this effect can be attributed to lower-level perception and higher-level cognition.

How do people in a precarious profession leverage technology to grow their business and improve their quality of life? Sex workers sit at the intersection of multiple marginalized identities and make up a sizeable workforce: the United Nations estimates that at least 42 million sex workers are conducting business across the globe. Yet, little research has examined how well technology fulfills sex workers’ business needs in the face of unique social, political, legal, and safety constraints.

Impossible spaces have been used to increase the amount of virtual space available for real walking within a constrained physical space. In this technique, multiple virtual rooms are allowed to occupy overlapping portions of the physical space, in a way which is not possible in real euclidean space. Prior work has explored detection thresholds for impossible spaces, however very little work has considered other aspects of how impossible spaces alter participants’ perception of spatial relationships within virtual environments. In this paper, we present a within-subjects study (n = 30) investigating how impossible spaces altered participants perceptions of the location of objects placed in different rooms. Participants explored three layouts with varying amounts of overlap between rooms and then pointed in the direction of various objects they had been tasked to locate. Significantly more error was observed when pointing at objects in overlapping spaces as compared to the non-overlapping layout. Further analysis suggests that participants pointed towards where objects would be located in the non-overlapping layout, regardless of how much overlap was present. This suggests that, when participants are not aware that any manipulation is present, they automatically adapt their representation of the spaces based on judgments of relative size and visible constraints on the size of the whole system.
