In recent years, the HCI community has recognized the need to address long(er) term information system design around on-going societal problems. Yet how to engage stakeholders effectively in multi-lifespan design thinking remains an open challenge. Toward that end, the work reported here extends an established envisioning method by introducing two new design methods, the multi-lifespan timeline and multi-lifespan co-design, with an emphasis on the element of (long) time. The new methods aim to stimulate participants' visions of future information systems by: (a) enhancing participants' understanding of longer timeframes (e.g., 100 years), and (b) guiding participants to effectively project themselves long into the future in their design thinking. We explored these multi-lifespan design methods in work with 51 Africans from Rwanda and the Great Lakes region living in the USA to understand the challenges and opportunities they envision for designing future information systems for transitional justice in Rwanda. Contributions are two-fold: (1) methodological innovation, and (2) a case study of multi-lifespan design thinking generated by diaspora members of post-conflict societies.

We describe the SAWUI architecture by which smartphones can easily show user interfaces for nearby appliances, with no modification or pre-installation of software on the phone, no reliance on cloud services or networking infrastructure, and modest additional hardware in the appliance. In contrast to appliances? physical user interfaces, which are often as simple as buttons, icons and LEDs, SAWUIs leverage smartphones? powerful UI hardware to provide personalized, self-explanatory, adaptive, and localized UIs.

While previous CSCW research has noted that computer scientists have their own research interests pertaining to cyberinfrastructure development projects, most have focused on the research imperatives of scientists. This qualitative, interview-based study investigates the perspective of computer scientists developing middleware software for cyberinfrastructures at two supercomputing centers. This paper examines how technologists develop and sustain middleware applications over time by leveraging expertise and partnering with different research domains in order to achieve long-term infrastructural goals.

While there has been substantial research into the use of online calendar systems (OCS) within organizations and families with children, no research focuses on adults without children. In our study, we focus on these OCS users' practices of calendar sharing as relationship work, the continually negotiated practice of managing friendships and intimacy. We conducted semi-structured interviews as part of a qualitative user study of Google Calendar users. We report the calendar sharing behaviors and strategies of our participants, who maintain multiple calendars for different purposes and with different users, communicating factual and emotional information through their calendar events. We contribute new knowledge by discussing four strategies derived from our participants' calendar sharing and relationship work activities.
