Music sharing as a computer supported collaborative application
TLDR
Opportunities to turn music sharing into a more collaborative and community-related activity are explored with the "Music Buddy", a system for browsing others' music collections without infringing the copyright of artists.
Interdisciplinary criticism: Analysing the experience of riot! a location-sensitive digital narrative
TLDR
A critical theory-based analysis of Riot! further explicates the user experience in terms of literary devices such as characterisation and the development of narrative expectation and identifies a number of usability problems such as inconsistency of interaction and non-reversibility that caused frustration.
Parallel worlds: immersion in location-based experiences
This paper analyses the stages and circumstances for immersion based on quantitative and qualitative feedback from 700 people who took part in a three week long public trial of a location-based audio
Security and Trust in Mobile Interactions: A Study of Users' Perceptions and Reasoning
TLDR
An investigation into the trust and security concerns of users who carry out interactions in ubiquitous and mobile computing environments, and a detailed analysis of the users’ reasoning about trust-related issues, draw conclusions about the design of secure interaction technologies for ubiquitous computing.
The Use of Conventional and New Music Media: Implications for Future Technologies
TLDR
Current practice with both conventional and new forms of media is explored, showing that rather than new music technologies replacing the old, they supplement current formats by allowing users to exploit a different set of affordances.
Sensing a live audience
TLDR
GSR data were synchronized with video footage of performers and audience, which enabled us to identify a strongly correlated main group of participants, describe the nature of their theatre experience and map out a minute-by-minute unfolding of the performance in terms of psycho-physiological engagement.
Shared Workspaces: How Do They Work and When Are They Useful?
TLDR
It is suggested that, for demanding text-based tasks, or for complex graphical tasks, there are overall benefits in adding a visual channel in the form of a Workspace, despite the costs involved in attempting to coordinate activity with this unfamiliar form of communication.
Energy-aware user interfaces and energy-adaptive displays
TLDR
It is shown that user interfaces must be designed with energy in mind, and that such energy-aware interfaces can actually provide a good combination of energy benefits and greater ease of use by leveraging features that improve usability instead of simply providing a tradeoff.
Energy-aware user interfaces: an evaluation of user acceptance
TLDR
The impact of emerging technologies that provide energy-saving display modifications on perceived ease of use, quality, and overall user acceptance is explored, and the tradeoffs between energy reduction and user acceptance for future interfaces are understood.
Design for emergence: experiments with a mixed reality urban playground game
TLDR
CitiTag is the mixed reality testbed, a wireless location-based multiplayer game based on the concept of playground ‘tag’, and the design and implementation of CitiTag are described and results from two user studies are discussed.
