論文アブストラクト： Empirical studies invariably show that data generation is situationally contingent and interpretively flexible, even when data is collected automatically. This essay situates data generation within a design perspective, demonstrating how data creation can be understood as a multilayered set of interlocking design activities. By showing how data is infused with design, this paper argues that any "use" of data represents a continuation of its design. We are always designers of data, never its mere appropriators.
論文アブストラクト： We are surrounded by a proliferation of connected devices performing increasingly complex data transactions. Traditional design methods tend to simplify or conceal this complexity to improve ease of use. However, the hidden nature of data is causing increasing discomfort. This paper presents BitBarista, a coffee machine designed to explore perceptions of data processes in the Internet of Things. BitBarista reveals social, environmental, qualitative and economic aspects of coffee supply chains. It allows people to choose a source of future coffee beans, situating their choices within the pool of decisions previously made. In doing so, it attempts to engage them in the transactions that are required to produce coffee. Initial studies of BitBarista with 42 participants reveal challenges of designing for connected systems, particularly in terms of perceptions of data gathering and sharing, as well as assumptions generated by current models of consumption. A discussion is followed by a series of suggestions for increasing positive attitudes towards data use in interactive systems.
論文アブストラクト： Widespread rumoring can hinder attempts to make sense of what is going on during disaster scenarios. Understanding how and why rumors spread in these contexts could assist in the design of systems that facilitate timely and accurate sensemaking. We address a basic question in this line: To what extent does rumor evolution occur (1) through reliance on a centralized information source, (2) in parallel information silos, or (3) through a web of complex informational interactions? We develop a conceptual model and associated analysis algorithms that allow us to distinguish between these possibilities. We analyze a case of rumoring on Twitter during the Boston Marathon Bombing. We find that rumor spreading was predominantly a parallel process in this case, which is consistent with a hypothesis that information silos may underlie the persistence of false rumors. Special attention towards detecting and resolving parallel information threads during collective sensemaking may hence be warranted.
論文アブストラクト： We introduce Quietto: an interactive timepiece made of molded concrete and milled wood. It shows upcoming daily schedules and the time through the quiet, ambient motions of a clock hand and light through the concrete touch interface. The results of an in-field user observation of 10 participants over 3 days showed the possibilities of using concrete as a unique and attractive material for designing a tangible interface due to its unexpected haptic feeling. We also found that Quietto provides an intuitive and effective representation of its users' daily schedules and can be used as a private, personal device. Through its distinctive design, Quietto can provide a new way of understanding scheduling through its concrete texture and amusing interaction qualities.
論文アブストラクト： Internet of Things (IoT) frequently involves conflicting interactions between devices and features that must be resolved to a single system state. The problem of feature interaction (FI) resolution has been investigated in Software Engineering through approaches that focus on verifiability but usually do not include the user in the evaluation. This paper bridges the gap between IoT approaches in HCI and Software Engineering by applying qualitative methods to understanding users' mental models of one representative FI resolution mechanism. Our contributions are in identifying common mental model errors and biases and how these may inform future IoT systems and research.
