Games can be powerful vehicles for gender identity exploration and self-reflection but are often subject to designers' biases including gender representation, limiting such opportunities. Using a game jam as a research-through-design method, alongside qualitative interviews with the creators, this paper explores how the process of creating games and the games themselves can facilitate exploration of and reflection on gender identity. We highlight aspects of identity people want to explore; how different game elements can support processes of exploring these, and what aspects are missing in games. Further, the process of creating and playing helped participants reflect on and reframe their understanding of gender regardless of their identity/experience. Finally, we reflect on the process of designing an inclusive jam around the topic of gender identity, which can be sensitive and divisive. Our work results in implications for the design of games and other potential tools for gender exploration.

As people's offline and online lives become increasingly entwined, the sensitivity of personal information disclosed online is increasing. Disclosures often occur through structured disclosure fields (e.g., drop-down lists). Prior research suggests these fields may limit privacy, with non-disclosing users being presumed to be hiding undesirable information. We investigated this around HIV status disclosure in online dating apps used by men who have sex with men. Our online study asked participants (N=183) to rate profiles where HIV status was either disclosed or undisclosed. We tested three designs for displaying undisclosed fields. Visibility of undisclosed fields had a significant effect on the way profiles were rated, and other profile information (e.g., ethnicity) could affect inferences that develop around undisclosed information. Our research highlights complexities around designing for non-disclosure and questions the voluntary nature of these fields. Further work is outlined to ensure disclosure control is appropriately implemented around online sensitive information disclosures.

Resulting from treatment advances, the Human Immunodeficiency Virus (HIV) is now a long-term condition, and digital solutions are being developed to support people living with HIV in self-management. Sharing their health data with their peers may support self-management, but the trust, identity, privacy and security (TIPS) considerations of people living with HIV remain underexplored. Working with a peer researcher who is expert in the lived experience of HIV, we interviewed 26 people living with HIV in the United Kingdom (UK) to investigate how to design a peer data sharing platform. We also conducted rating activities with participants to capture their attitudes towards sharing personal data. Our mixed methods study showed that participants were highly sophisticated in their understanding of trust and in their requirements for robust privacy and security. They indicated willingness to share digital identity attributes, including gender, age, medical history, health and well-being data, but not details that could reveal their personal identity. Participants called for TIPS measures to foster and to sustain responsible data sharing within their community. These findings can inform the development of trustworthy and secure digital platforms that enable people living with HIV to share data with their peers and provide insights for researchers who wish to facilitate data sharing in other communities with stigmatised health conditions.

While digital technologies are increasingly being used to provide support and diagnoses remotely, it is unclear whether they offer adequate emotional support and appropriate messages in navigating complex, stigmatised and sensitive conditions that can have a momentous impact on people's lives. In this paper, we investigate how and why people access existing HIV resources, and their experiences of using these resources through a survey with 197 respondents and an interview and think-aloud study with 28 participants. Our findings indicate that many HIV-related resources do not address the anxiety-provoking reasons for access, reinforce stigma and neglect to provide important information and emotional support. We finally discuss potential ways of addressing these issues in the current environment where more sexual health services are being delivered online.

HIV status disclosure fields in online sex-social applications ("apps") are designed to help increase awareness, reduce stigma, and promote sexual health. Public disclosure could also help those diagnosed relate to others with similar statuses to feel less isolated. However, in our interview study (n=28) with HIV positive and negative men who have sex with men (MSM), we found some users preferred to keep their status private, especially when disclosure could stigmatise and disadvantage them, or risk revealing their status to someone they knew offline in a different context. How do users manage these tensions between health, stigma, and privacy? We analysed our interview data using signalling theory as a conceptual framework and identify participants developing 'signal appropriation' strategies, helping them manage the disclosure of their HIV status. Additionally, we propose a set of design considerations that explore the use of signals in the design of sensitive disclosure fields.
