Research seminar

Shape-Changing Interface Research: Small Steps To Address Grand Challenges.

Presenter: Tim Merritt

04 November 2018, 09:30-10:30

Abstract: In this seminar, I will review the topic of “Shape-Changing Interfaces,” taking departure in our recent paper identifying “grand challenges” for the research community (Alexander et al 2018). Shape-changing interfaces have emerged as a new method for interacting with computers, using dynamic changes in a device’s physical shape for input and output. Roots of this research begin with Ivan Sutherland’s Ultimate Display (Sutherland 1965), which was a concept proposing a future in which a computer can “control the existence of matter.” Shape-changing interfaces change our fundamental approach to interaction design, expanding interactive systems to include our perceptual motor skills to support the same direct interaction our body has with the everyday world. They take advantage of our haptic and kinaesthetic senses, our instinctive perception of physical 3D forms, and provide inherent support for multi-user interaction. In this talk, I will show various examples from recent research that has made progress exploring and addressing the grand challenges. A critical perspective is adopted in the end of the seminar to temper the enthusiasm and to present possible “dark patterns” for shape-changing interfaces to show how things might go wrong in the future. I invite discussion to explore dark patterns and to help map out opportunities for addressing the grand challenges.

Designing the Desirable Smart Home: A Study of Household Experiences and Energy Consumption Impacts

Presenter: Rikke Hagensby Jensen

06 October 2018, 09:30-10:30

Research has shown that desirable designs shape the use and experiences people have when interacting with technology. Nevertheless, how desirability influences energy consumption is often overlooked, particularly in HCI studies evaluating the sustainability benefits of smart home technology. In this paper, we present a qualitative study with 23 Australian households who reflect on their experiences of living with smart home devices. Drawing on Nelson and Stolterman’s concept of desiderata we develop a typology of householders’ desires for the smart home and their energy implications. We structure these desires as three smart home personas: the helper, optimiser and hedonist, which align with desiderata’s three approaches to desire (reason, ethics and aesthetics). We use these insights to discuss how desirability can be used within HCI for steering design of the smart home towards sustainability.

Research seminar

The connected digital music ecosystem (DigiMUSE)

Presenter: Jesper Kjeldskov

17 August 2018, 09:30-10:30

In this HCC seminar, I will present some of the ideas from the DigiMUSE project proposal, which was shortlisted for an AAU strategy grant. Music is a central fabric of society, connecting us across age, culture, geography, and other divides. An important aspect of enabling connected societies with ICT is, therefore, to work with our music industry on its digital transformation towards a contemporary and sustainable industry 4.0. Such transformation can happen by fully embracing ICT for connecting artists, technology and service providers, distributors, and consumers in new ways, that are profitable and valuable, and sustainable for all. However, the knowledge and tools for achieving this do not yet exist. In response, we ask how can we enable a sustainable digital ecosystem for community-driven creation, distribution and consumption of music and new music expressions and experiences? This is essentially a “wicked problem” requiring interdisciplinary research, as possible solutions will have to involve new combined knowledge for the world within technology, art/media, and business, juxtaposing the challenges and opportunities offered by these. Specifically, our core idea is to emancipate and change the creation, distribution, consumption, and expression/experience of music by conceiving and deploying new ICT-enabled systems, methods, and business models of a “connected digital music ecosystem”.

Research seminar

Longitudinal Studies in HCI

Presenter: Maria Kjærup

17 November 2017, 09:30-10:30

Longitudinal studies have been discussed and applied in HCI research for many years, and research has stressed the importance of such studies. But it has also traditionally been seen as somewhat cumbersome and labour-intensive. As a result, the actual role and significance of longitudinal studies in HCI research is still vaguely understood. In this presentation, I will present some interesting findings following a meta-analysis of 97 CHI papers retrieved from the period 1982-2017 in which longitudinal studies were reported. Also reported in a submission for CHI’18, with fellow colleagues and authors; Mikael, Peter and Jesper. The focus will be on themes; duration, metrics and change. Let’s open up a discussion on implications and possibilities for longitudinal studies in HCI.
