This paper presents Fractured Objects for the design of virtual and mixed-reality experiences. Drawing on the qualitative analysis of three weeks of artistic activities within a residency program, we present six types of Fractured Objects that were used in sketching a mixed-reality performance. Building on these Fractured Objects, as they were articulated by the artists, we present speculative designs for their use in scenarios inspired by research within the IMX community. In discussion, we look to expand the concept of Fractured Objects by relating it to other design concepts such as Seamful Design and Wabi-Sabi, and explore the relationship to the temporality of interaction. We introduce Kintsugi VR with Fractured Objects, drawing on the concept of 'golden repair' in which the act of reconnecting fractured parts improves the resulting whole object.

With growing interest in how technology can make sense of our body and bodily experiences, this work looks at how these experiences are communicated through and with the help of technology. We present the ways in which knowledge about sleep, and how to manipulate it, is collectively shared online. This paper documents the sleep-change practices of four groups of 'Sleep Hackers' including Nurses, Polyphasic Sleeper, Over-sleepers, and Biohackers. Our thematic analysis uses 1002 posts taken from public forums discussing sleep change. This work reveals the different ways individuals share their experiences and build communal knowledge on how to 'hack' their sleep -- from using drugs, external stimulation, isolation, and polyphasic sleeping practices where segmented sleep schedules are shared between peers. We describe how communal discussions around the body and sleep can inform the development of body sensing technology. We discuss the opportunities and implications for designing for bodily agency over sleep changes both in relation to collaboratively developed understandings of the body and social context of the user. We also discuss notions of slowly changing bodily processes and sensory manipulation in relation to how they can build on the exploration of soma-technology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
