Colour in spaces plays an important role on inhabitants' mood. In interior design colour has been used to decorate spaces in order to lift and change mood in people. It has been already proved that certain colours relax people while other colours have an opposite e ect. However, not all the colours have been researched, and especially their e ects on teenagers' moods have not been researched. This paper begins research in this area by presenting the ndings of a study seeking to understand how teenage boys relate to colour, and seeking to identify what their favourite colour is. The teenagers completed a questionnaire about colour and the results show white is a dominant choice for bedroom design followed by blue, black, green, violet, red, grey, yellow, and orange. Red and blue were on top as favourite colours, followed by white, purple and green being preferred once each. Thursday 1.30pm 3:00pm Design Windsor 2 Full: Participatory Research with Older Adults with AMD: Co-Designing a SMART Diet Diary App Lilit Hakobyan, Jo Lumsden and Dympna O'Sullivan The global population of people aged 60 years and older is growing rapidly. In the UK, there are currently around 10 million people aged 65 and over, and the number is projected to rise by 50% in the next 20 years (RNIB, 2013). While ongoing advances in information technology (IT) are undoubtedly increasing the scope for IT to enhance and support older adults’ daily living, the digital divide between older and younger adults – 43% of people below the age of 55 own and use a smartphone, compared to only 3% of people aged 65 and over (AgeUK, 2013) – raises concerns about the suitability of technological solutions for older adults, especially for older adults with impairments. Evidence suggests that sympathetic design of mobile technology does render it useful and acceptable to older adults: the key issue is, however, how best to achieve such sympathetic design when working with impaired older adults. We report here on a case study in order to outline the practicalities and highlight the bene ts of participatory research for the design of sympathetic technology for (and importantly with) older adults with impairments. Short: Authorisation in Context: Incorporating Context-Sensitivity into an Access Control Framework Shamal Faily, John Lyle, Ivan Flechais, Andrea Atzeni, Cesare Cameroni, Hans Myrhaug, Ayse Goker and Robert Kleinfeld With sensitive information about ourselves now distributed across personal devices, people face an increasing need to make access control decisions for di erent contexts of use. However, despite advances in improving the usability of access control for both developers and users in recent years, we still lack insights about how the intentions behind policy decisions in di erent contexts of use are shaped. In this paper, we describe how context was incorporated into an access control framework using a study of how context in uences access control decision making. We describe how the main recommendations arising from this study were used to build context into a policy editor for this access control framework. Short: Eliciting Domain Knowledge Using Conceptual Metaphors to Inform Interaction Designs: A Case Study from Music Interaction Katie Wilkie, Simon Holland and Paul Mulholland. Interaction design for domains that involve complex abstractions can prove challenging. This problem is particularly acute in domains where the intricate nature of domain-speci c knowledge can be di cult for even the most experienced expert to conceptualise or articulate. One promising solution to the problem of representing complex domain abstractions involves the use of conceptual metaphors. Previous applications of conceptual metaphors to abstract domains have yielded encouraging results. However, the design of appropriate methods for eliciting conceptual metaphors for the purposes of informing interaction design remains an open question. In this paper, we report on a series of studies carried out to elicit conceptual metaphors from domain experts, using music as a case study, re ecting on the bene ts and drawbacks of each approach. Thursday Short: Non-use of Automated Border Control Systems: Identifying Reasons and Solutions Anne-Marie Oostveen There are many reasons why passengers are unable or reluctant to use self-service e-gate systems. In order for designers to build better systems with higher uptake by end-users they need to have a more thorough understanding of the non-users. This paper investigates the reasons of non-use of Automated Border Control at European airports by applying Wyatt’s taxonomy and adding an "unawares" category. It also presents possible solutions to turn current non-users into future users of e-gates. INTERACTING WITH COMPUTERS General Editor: Dianne M.

Fonseca and Joana Pinto Although personal tastes may change over time, overall people still enjoy music they have not listen to for some time or not very often. However, most solutions for browsing music collections do not focus on showing or suggesting these songs to create serendipitous rediscoveries. Instead they promote most recently played songs as an entry point for browsing and playing music. This way, users are constantly listening to the same music, causing the least heard to become forgotten. In this paper, we present BACH, an interactive visualization and exploration tool for personal music collections that uses the listening history of the user to in uence the songs suggested and the way they are presented to him/her. Our goal is to help users rediscover their music collection for di erent periods of the day through the perspective of their listening history. Experimental results revealed that users understood and enjoyed our solution and that they were able to rediscover their collections by listening to songs heard some time ago. Thursday After discussion over lunch, three new groups will be formed by participants to de ne and plan speci c activities that will create the climate for this recombination to occur successfully and lead to • greater external in uence for HCI in the overall computing curriculum • more immediate access by educators at the point of need to the plethora of HCI resources • requirements for designers of MOOCs to meet the needs of learners by applying HCI principles 3.00pm 3.30pm Co ee and Tea Break (Location: Windsor 1) Short: Dynamic Presentation of Synchronised Photo Streams Sam Zargham and Janko Calic Abstract: Although personal tastes may change over time, overall people still enjoy music they have not listen to for some time or not very often.

WIP: Interactive Visualization of Video Tours in Space and Time Ana Jorge, Sérgio Serra and Teresa Chambel Video is being used at huge extend to shoot trajectories that are later shared over the internet. Navigate and access this kind of information is very di cult due to the amount of items available and their inner complexity. It is mandatory to catalogue videos properly in order to make them useful, and moreover, make the navigation ludic and aesthetically interesting. In previous work we focused the time concept on institutional videos in a way that is possible to explore, and access them through time, genre and rating criteria; and the space inside their contents regarding image, movement, audio, and subtitles, with a focus on emotions. We are now extending our goal by considering the spatial dimension. We present the design of three main interactive visualizations for navigating geo-referenced videos, allowing the user to 1) overview the amount of videos, and movies shot in a given geographic location in a given moment of time, e.g. by user generated versus institutional movies, time of the shootings, rating and number of the viewings; 2) zoom in the trajectories e.g. by length, speed and age of the shootings; 3) detail the contents of each trajectory e.g. by color, environment sound, spoken words, and neighbor connections; 4) navigate inside the contents adding criteria e.g. movement and emotions associated with the shooting.

Thursday 3.30pm 4:30pm Input, Navigation & Displays Windsor 2 Short: Non-Visual Menu Navigation: the E ect of an Audio-Tactile Display Oussama Metatla, Nick Bryan-Kinns, Tony Stockman and Fiore Martin. We present a preliminary study examining non-visual menu navigation in terms of task completion times and cognitive workload. We asked 12 participants to locate items on menus presented using visual, audio-only and audio-tactile displays on a touch screen mobile device and found that users were signi cantly slower in locating an item on a menu when using an audio-tactile menu display. This di erence in performance was not re ected in the users' subjective workload assessments. We discuss the implications of these ndings in terms of cross-modal display and the design of menu navigation gestures on touch screen devices. WIP: Challenges of using stereoscopic displays in a touch interaction context Chris P. Bowers, Benjamin Cowan, Chris Creed and Gido Hakvoort This work examines how common use scenarios for touch interactive stereoscopic displays might exacerbate visual fatigue. We identify technological constraints of current stereoscopic displays and image separation techniques as the potential underlying cause and generate a set of hypotheses concerning the implications for end users. Furthermore we outline a proposed study to examine these hypotheses. WIP: CrowdHiLite: A Peer Review Service to Support Serious Reading on the Screen Nan Jiang and Huseyin Dogan The advent of smart devices and consumerisation of IT has produced a signi cant and permanent shift away from print-based reading to digital reading. This, in turn, has changed people’s reading behaviours and suggests that adapted mechanisms should be considered to support digital reading. It is particularly important for novice readers who need to read in-depth scienti c literature in their chosen eld. In this paper, we propose CrowdHiLite, a novel service architecture that allows expert readers to provide suggestion on individual readers’ highlights to support their reading on the screen through the use of crowdsourcing technique. A demonstration was also provided to show how it would work in real world. A preliminary experiment comparing novice readers’ reading performance with expert rated highlights and normal highlights on the same document found improved reading e ciency and comprehension with the former. 7:00pm Conference Dinner Ramada Hotel (Meet in Clifton Hotel bar at 6.30pm or at the Ramada Hotel at 7pm) Thursday
