Making multiple uses of the obscura 1C digital camera: Reflecting on the design, production, packaging and distribution of a counterfunctional device
This paper describes and explains details of the design, production and packaging of a counterfunctional device: The Obscura 1C Digital Camera. We further describe a small-scale distribution of Obscura 1C packages into everyday contexts. The paper then reflects on the various types of conceptual, imaginary and firsthand uses made of the Obscura 1C. These include its uses for everyday audiences as a unique camera and as a conceptually usable device. But we also prioritize uses particular to the HCI and design audience. These include using the Obscura 1C to articulate the concepts of inhibitive interfaces, counterfunctionality, and enabling limitations. The Obscura 1C is further used to articulate how abstract ideas can be translated into material forms, to rethink the role of packaging in user studies, and to draw attention to how discursive design objects are packaged and presented

Counterfunctional things: Exploring possibilities in designing digital limitations
This paper presents a set of design studies and discussions investigating new possibilities in designing digital limitations. Focusing on digital photography as a medium, we present design prototypes and experiments including Ultra-Low Resolution Displays, Inaccessible Cameras, and a set of point-and-shoot digital camera variants. Our design work is based on the concept of a counterfunctional thing-a thing that figuratively counters some of its own functionality. We present the concept of counterfunctionality as a way of approaching the design of interactive technology. In conclusion we connect our work with critical discourses surrounding technology and the value of designing limitations. Copyright © 2014 ACM
An exploratory study to design constrained engagement in smart heating systems
Smart heating systems that leverage complex models of user preferences and energy consumption within the home and the wider network in order to make intelligent heating decisions have started to be adopted in homes. While heating systems that allow the user to directly manipulate the heating schedule and temperature have been investigated in some detail, little is known about how to strike a balance between encouraging users to interact with the system but not to demand too much of their attention, what research has termed "constrained engagement" with calm technology. In this exploratory study, we investigated how participants responded to a number of scenarios involving a novel smart heating system in order to support controllability, intelligibility and user experience as part of a constrained engagement approach. We focused in particular on when participants wanted to engage with the smart heating system and how explanations from the system could influence user engagement. Our study contributes a better understanding of users' expectations towards smart heating systems that can form the basis of improved user interfaces
Deep Underground Neutrino Experiment (DUNE), Far Detector Technical Design Report, Volume II: DUNE Physics
The preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decay -- these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. DUNE is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector technical design report (TDR) describes the DUNE physics program and the technical designs of the single- and dual-phase DUNE liquid argon TPC far detector modules. Volume II of this TDR, DUNE Physics, describes the array of identified scientific opportunities and key goals. Crucially, we also report our best current understanding of the capability of DUNE to realize these goals, along with the detailed arguments and investigations on which this understanding is based. This TDR volume documents the scientific basis underlying the conception and design of the LBNF/DUNE experimental configurations. As a result, the description of DUNE's experimental capabilities constitutes the bulk of the document. Key linkages between requirements for successful execution of the physics program and primary specifications of the experimental configurations are drawn and summarized. This document also serves a wider purpose as a statement on the scientific potential of DUNE as a central component within a global program of frontier theoretical and experimental particle physics research. Thus, the presentation also aims to serve as a resource for the particle physics community at large
Deep Underground Neutrino Experiment (DUNE), Far Detector Technical Design Report, Volume I Introduction to DUNE
International audienceThe preponderance of matter over antimatter in the early universe, the dynamics of the supernovae that produced the heavy elements necessary for life, and whether protons eventually decayâthese mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our universe, its current state, and its eventual fate. The Deep Underground Neutrino Experiment (DUNE) is an international world-class experiment dedicated to addressing these questions as it searches for leptonic charge-parity symmetry violation, stands ready to capture supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector technical design report (TDR) describes the DUNE physics program and the technical designs of the single- and dual-phase DUNE liquid argon TPC far detector modules. This TDR is intended to justify the technical choices for the far detector that flow down from the high-level physics goals through requirements at all levels of the Project. Volume I contains an executive summary that introduces the DUNE science program, the far detector and the strategy for its modular designs, and the organization and management of the Project. The remainder of Volume I provides more detail on the science program that drives the choice of detector technologies and on the technologies themselves. It also introduces the designs for the DUNE near detector and the DUNE computing model, for which DUNE is planning design reports. Volume II of this TDR describes DUNE's physics program in detail. Volume III describes the technical coordination required for the far detector design, construction, installation, and integration, and its organizational structure. Volume IV describes the single-phase far detector technology. A planned Volume V will describe the dual-phase technology
