Abstract: We designed the system to manage, verify and exchange identity information for Namibia's national Digital-ID. We applied Grounded Theory methods to five focus groups to understand experiences, expectations and practices in different contexts of legal identity verification and sharing. Local perspectives on privacy aligned with prevalent models for Digital-ID, in which people in idually own and trade their personal information, yet they cannot be disentangled from specific social relationships. Thus, our design responds to the ways people establish trust with organisations over time and relate consent for information exchange and privacy control to accountability. We used Situational Analysis to consider how data governance is constructed in a policy-design-adoption ‘knot’ and relates to Namibia's sociotechnical imaginary of ‘unity in ersity’. Unequal telecommunications access and adoption contributes to systems that produce inegalitarian data relations but is not central in Namibia's data protection and privacy discourse, thus our thick analysis prompted designing to strengthen collective voice in governance through Government Gazettes and civil society activism. Our reflections also suggest that while design research of a real-world system in Africa offers important insights about combining in idualist and collectivist orientations in data governance, their wider scholarly contribution is impeded by norms imposed by the Global North.

Abstract: To detect motion, primates, birds and insects all use local detectors to correlate signals s led at one location in the image with those s led after a delay at adjacent locations. These detectors can adapt to high image velocities by shortening the delay. To investigate whether they use long delays for detecting low velocities, we compared motion-sensitive neurons in ten species of fast-flying insects, some of which encounter low velocities while hovering. Neurons of bee-flies and hawkmoths, which hover, are tuned to lower temporal frequencies than those of butterflies and bumblebees, which do not. Tuning to low frequencies indicates longer delays and extends sensitivity to lower velocities. Hoverflies retain fast temporal tuning but use their high spatial acuity for sensing low-velocity motion. Thus an unexpectedly wide range of spatio-temporal tuning matches motion detection to visual ecology.

Abstract: We consider practices that sustain social and physical environments beyond those dominating sustainable HCI discourse. We describe links between walking, sociality, and using resources in a case study of community-based, solar, cellphone charging in villages in South Africa's Eastern Cape. Like 360 million rural Africans, inhabitants of these villages are poor and, like 25% and 92% of the world, respectively, do not have domestic electricity or own motor vehicles. We describe nine practices in using the charging stations we deployed. We recorded 700 people using the stations, over a year, some regularly. We suggest that the way we frame practices limits insights about them, and consider various routines in using and sharing local resources to discover relations that might also feature in charging. Specifically, walking interconnects routines in using, storing, sharing and sustaining resources, and contributes to knowing, feeling, wanting and avoiding as well as to different aspects of sociality, social order and perspectives on sustainability. Along the way, bodies acquire literacies that make certain relationalities legible. Our study shows we cannot assert what sustainable practice means a priori and, further, that detaching practices from bodies and their paths limits solutions, at least in rural Africa. Thus, we advocate a more “alongly” integrated approach to data about practices.

Abstract: Despite the increase in university courses and curricula on the ethics of computing there are few studies about how CS programs should account for the erse ways ethical dilemmas and approaches to ethics are situated in cultural, philosophical and governance systems, religions and languages. We draw on the experiences and insights of 46 university educators and practitioners in Latin America, South-Asia, Africa, the Middle East, and Australian First Nations who participated in surveys and interviews. Our modest study seeks to prompt conversation about ethics and computing in the Global Souths and inform revisions to the ACM's curricular guidelines for the Society, Ethics and Professionalism knowledge area in undergraduate CS programs. Participants describe frictions between static and anticipatory approaches to ethics in globalised regulations and formal Codes of ethics and professional conduct, and local practices, values and impacts of technologies in the Global Souths. Codes and regulations are instruments for international control and their gap with local realities can cause harm, despite local efforts to compensate. However, our insights also illustrate opportunities for university teaching to link more closely to priorities, actions and experiences in the Global Souths and enrich students’ education in the Global North.

Abstract: Our recent study [O'Carroll et al. (1996). Nature 382, 63-66) described a correlation between the spatio-temporal properties of motion detecting neurons in the optic lobes of flying insects and behaviour. We consider here theoretical properties of insect motion detectors at very low image velocities and measure spatial and temporal sensitivity of neurons in the lobula complex of two specialised hovering insects, the bee-fly Bombylius and the hummingbird hawkmoth, Macroglossum. The spatio-temporal optima of direction-selective neurons in these insects lie at lower velocities than those of other insects which we have studied, including large syrphid flies, which are also excellent hoverers. We argue that spatio-temporal optima reflect a compromise between the demands of erse behaviour, which can involve prolonged periods of stationary, hovering flight followed by spectacular high speed pursuits of conspecifics. Males of the syrphid Eristalis which engage in such behaviour, have higher temporal frequency optima than females. High contrast sensitivity in these flies nevertheless results in reliable responses at very low image velocities. Neurons of Bombylius have two distinct velocity optima, suggesting that they sum inputs from two classes of motion correlator with different time constants. This also provides sensitivity to a large range of velocities.

Abstract: Being in nature is often regarded to be calming, relaxing and purifying. While technology has the potential to support engagement with nature, developing systems that provide support in an unobtrusive manner holds many challenges for interaction design. In this article, the authors describe their reflections around the NatureCHI workshop series. The aim with the workshops has been to help foster a research community interested in the design of Unobtrusive User Experiences with Technology in Nature. The first of two workshops ran as part of CHI 2016 in San Jose, California, while the second workshop took place alongside MobileHCI 2017 in Vienna, Austria. With 25 papers presented in total, the workshops demonstrate a rising interest in the areas where nature and interactive technologies meet.

Abstract: This article contributes to research that aims to better understand and describe the rural context for rural computing. We argue that the particularities of rurality are heightened by the experience of ‘islandness’. We report on our experiences of engaging on one small island as islanders established community radio using a novel platform. Data comes from 12 semi-structured interviews with community members and ethnographic field notes assembled through eight researcher visits to the island. Transcripts and notes were analysed using thematic analysis. We discuss how rural islandness as a socio-cultural lens influenced technology appropriation and factors to support participation. We explore the elements of rural islandness that can be used as an analytic tool for rural HCI and HCI more broadly, through three main contributions of rural islandness that we believe have not yet been sufficiently explored in HCI. These are (1) separateness, (2) pushing things ahead, and (3) publics and rural pluralities.

Abstract: Shared use of small-scale natural commons is vital to the livelihoods of billions of rural inhabitants, particularly women, and advocates propose that local telecommunications systems that are oriented by the commons can close rural connectivity gaps. This article extends insights about women's exclusion from such Community Networks (CNs) by considering ‘commoning’, or practices that produce, reproduce and use the commons and create communality. I generated data in interviews and observations of rural CNs in seven countries in the Global South and in multi-sited ethnography of international advocacy for CNs. Male biases in technoculture and rural governance limit women's participation in CNs, and women adopt different approaches to performing their communal identity while using technology. This situation contributes to detaching CNs from relations that are produced in women's commoning. It also illustrates processes that co-opt the commons in rural technology endeavours and the erse ways commoners express their subjectivities in response.

Abstract: Abstract Community Networks (CNs) can provide access to telecommunications in low-income rural areas that are excluded by dominant connectivity models. Women and older people often constitute relatively higher proportions of these populations, thus this paper explores interactions between technology, gender and age in three CNs in rural Africa, Latin America and South Asia. All cases are situated both in local governance structures dominated by men, including a tribal authority, indigenous assembly, and a village council and in collectivist cultures where women are involved in community work but not in decision-making. I generated data about people’s everyday practices and opinions in relation to their local CNs in focus group discussions and interviews of different sorts with 76 men and 60 women, including network initiators, ch ions, operators, users and non-users. Older women significantly contributed volunteer labour but were less likely to use their CN, for instance because they did do not own/know how to use devices, or because the location of hotspots was unsuited to their daily lives. Meanwhile, younger women frequently used alternatives to the CNs for connectivity and sometimes established their own enterprises in this which contributed to some older women’s perspectives that younger women were increasingly separated from communal traditions. This has the potential to lify generational gaps amongst women and patriarchy within CNs. Such isive potential may be further exacerbated by masculine bias of priorities in global discourse on telecommunications technology and policy, which tends to emphasise certain concerns about access over concerns about power relations embedded in infrastructure.

Abstract: Licencing frameworks are embedded with sociotechnical imaginaries that limit the potential for networked technologies to make traditional media forms, like radio, more inclusive. We sought to refine and extend a platform, RootIO, which aims to enable erse people to run small radio stations by using internet and mobile networks that avoid the costs of studios and specialist equipment. We situated design and refinement in the activities of groups that set up and ran four community stations in rural Romania and some Irish islands over three-years and found national regulations limited who articulated requirements. Activities in applying for, and complying with, licences shaped design priorities, embedded temporal demands, certain organisational structures and ision of responsibilities, and assumptions about studios and professionalism. Indeed, small radio stations are subject to the same values as large media corporations that pursue market power. Regulatory frameworks are specific to nations and media form, yet our analysis illustrates that they impede designing platforms to widen inclusion by enacting broader sociotechnical imaginaries. We hope this reflection provokes discussion, in HCI and CSCW, about our responsibilities in engaging with the policies that shape possible futures.
