My research year 2008 can be summarised as two main activities: first 4 months of intensive knowledge acquisition and design process for interactive TV, followed by 8 months of dissemination activities for that.

My design process had a form of learning and understanding the medium characteristics of iTV, and continuous revisions of sketching and prototyping of my own design strategies with discussion with the project members. I was surprised how little the iTV community current knows about iTV UI design... for example, there are only handful of design guidelines available for iTV UI, and some of them quite contradict with each other. There is no established convention, no standardised widget sets - this meant I had to invent widgets and interaction strategies all by myself from the scratch.

Then I wrote my perspective of the design and the detailed design rationale on this design, and published. I had 10 air trips this year on business, including 3 long-howl trips: 2 trips to Korea (April and September) for project meeting with Samsung Electronics, Silicon Valley (October) for uxTV 2008 (most enjoyable conference I've been to!), Naples (May) for AVI/PPD, Salzburg (July) for EuroITV 2008, London (June) to see interactive wall, research visit to Amsterdam (June), seminars at Edinburgh (September), Glasgow (November) and Brighton (December). Lots of trips!

This is also the year I was awarded DCU Research Fellowship from the University - it will support me for next 2 years.

I was also engaged in a number of funding proposal writing, including the ones I'm writing at this moment (10 minutes to New Year!)

More detailed summary below.



Seminar at the Interactive Technologies Research Group, University of Brighton (8 December)
I visited the group in Brighton and presented my work on interaction design for multimedia technologies. It was great to talk to the group as their expertise in interactive TV and HCI perspective is something I was very interested in.

Attending SIGCHI Ireland Chapter inaugural lecture by Prof Alan Dix (2 December)
Daragh, Naz, Yuki and I attended the inaugural lecture by Alan Dix at Trinity College, titled 'Human-Computer Interaction in the Early 21st Century: a Stable Discipline, a Nascent Science, the Growth of the Long Tail.' (More details)

Seminar at Glasgow Interactive Systems Group (GIST) and IR group, Glasgow University (20 November)
I visited the both groups at the same time and presented and discussed my research work on interaction design for multimedia. Interesting point was that my seminar tried to bring together the IR group (highly-techy) and GIST group (user-focused), as my research area is the intersection of both areas.

Demos at DCU Open Day (21-22 November)
It was DCU Open Day and I helped with Sorin and Aiden, the setting of our demos: interactive TableTop and TV interfaces - they gathered a lot of crowd because they project new media platforms and the future use of our media technologies.

Alia (CWI, Amsterdam)'s visit to CDVP (17-28 November)
Alia Amin from CWI visited our group for 2 weeks and I had many discussions on interaction design, especially in developing her fancy museum interface. Alia's group is led by Prof Lynda Hardman, who also visited 2 days during Alia's visit, and I've visited her group in Amsterdam 3 times over the last 2 years.

CLARITY away day (5-6 November)
I participated in the 2-day meeting in Carlow to discuss and shape the demonstrators for CLARITY Centre.

Awarded DCU Research Fellowship! (October)
I was awarded DCU Research Fellowship, a competitive scheme to help researchers to establish as leaders in their fields.

Presenting a paper at uxTV 2008, Silicon Valley (22-24 October)
I presented a full paper at uxTV (First International Conference on Designing Interactive User Experiences for TV and Video) Mountain View this October. The paper I wrote is a full design rationale of the interactive TV interface - I spent January - April almost full-time this year, reading the relevant literature to identify design issues and guidelines on interactive TV (had a great time checking on EuroITV conference series proceedings), brainstorming and sketching the interface. My challenge was to incorporate some of our group's content-based analysis techniques in the interactive TV and represent on its interface where the interaction needs to be extra-simple. How can those seemingly sophisticated, advanced features of multimedia techniques be reflected on an a TV screen where simplicity should rule? With layered interface sophistication level, semi-transparent interactive elements, query without text input and colour-button short-cut keys on the remote control, my design solution shows a remarkably simple but effective interface that leverages multimedia techniques for simple TV interface.

Attended a workshop 'Supervising Postgraduate Students and Early Stage Researchers in an Academic Context', invent, DCU (16 September)
I attended the half-day training event in DCU, in order to understand better the best way to work with research students.

Seminar at Napier University, Edinburgh (12 September)
I was invited by the Centre for Interaction Design, Napier University, Edinburgh - my second visit to the group. I gave a seminar on updates of my past 10 months of research. I enjoy visiting this group as their perspective and feedback has been always inspiring and useful.

ODCSSS supervision for summer (June - July)
As last summer, this summer I again supervised a student for ODCSSS (Online Dublin Computer Science Summer School). My student, Anmol, worked on a project titled "online sharing of environmental data to enhance awareness" and we worked together to investigate the best way to allow connection of central/local environmental data together and get the users in the community aware of these data.

Presenting Industrial Case Study at the EuroITV 2008, Salzburg (2-4 Jul)
I attended the 6th European Interactive TV Conference as well as a tutorial (pre-conference event) on HCI Methods in Digital TV Applications. I had a paper to demonstrate the interactive TV interface at the Industrial Case Studies of the event. The event brought in iTV researchers around the world, and discussed the issues especially the identify of the community and where iTV is heading towards. Certainly the most important issues dealt with was how interactive TV identifies itself as in the coming era - convergence of Internet and TV, along with bringing social features to TV was the hot issue. Firt time to be at the conference series, I met many people in the iTV community, and also it was the most well-organised conference I have been for a long time.

Visiting CWI Amsterdam (11-12 June)
I visited CWI to discuss the interfaces we are developing. Representing underlying technology to the interface is always a difficult issue partly because by being deeply involved in the development of the technology, we lose a perspective from outside and how such technology should be interfaced to outside world. Having our own agenda, our own ways of understanding, our own ways of approach, our own ways to categorise and classify our problems tend to lead us to design the interface that truthfully represent in our own ways, but in many cases such an interface doesn't work. The ability and skill of a good interface designer in new technology is to see this and start afresh in designing the interface from point zero. Design is to make the message clear to the users - how can we make all our complicated concepts and ideas (however powerful we think they are) easy to understand and guide the users in a simple, straightforward manner? My visit to CWI highlighted this point.

Interactive Wall survey (April - August)
I've been investigating interactive wall product for our group - I visited places to see example products and currently compiling a list of suggestions in order to help make decision on which to purchase. The wall is usually about 4m x 1.5m vertical screen where a user can approach and interact with her finger/hand. This will extend our interaction design expertise from Web/GUI, mobile, TableTop, and interactive TV.

Attended Enterprise Ireland Information Workshop, invent, DCU (5 June)
I am more and more aware of the possible funding opportunities, and trying to get more information about these available sources. I attended the workshop to understand these opportunities offered by Enterprise Ireland.

Attending AVI 2008 and presenting at PPD 2008 in Naples, Italy (28-31 May)
I attended AVI 2008 conference (International Working Conference on Advanced Visual Interfaces), and also presented a paper at PPD 2008 (Workshop on Designing Multi-Touch Interaction Techniques for Coupled Public and Private Displays) for Xiangan, who is the primary author of our paper.

Attending Open Access to Research - A Celebration, Trinity College (16 May)
From February, I have been liasing with DCU library in order to get the DCU participation of the IREL-Open project active, by collecting papers for DORAS (DCU Online Research Access Service), where now many of our group's papers are available in their camera-ready (but pre-publication) format. The event at the Science Gallery, Trinity College, was to celebrate the collection of activities from 7 Irish universities and its future direction.

Paper writing on designing interactive TV - EuroITV 2008 and UXTV 2008 (Apr-May)
I wrote a paper for EuroITV (and subsequently accepted) - European Conference on Interactive TV, Salzburg, Austria. Main focus of the paper is the dilemma we have when trying to incorporate sophisticated multimedia techniques to an interactive TV (which needs to be extremely simplistic in its interface). A much longer, full paper I also wrote in May, for UXTV 2008 - International Conference on Designing User Experience for TV and Video, Silicon Valley, U.S. to be held October this year.

Visit to Samsung Electronics, Korea (8-11 Apr)
Cathal, Paul and I went to Korea to have meeting with Samsung Electronics, for a mid-point progress meeting on the interactive TV project. I presented a 1.5-hour long presentation to Samsung researchers on our findings and designs for the interactive TV application that incorporates multimedia IR features.

Design of Interactive TV Interface (Jan - Sep)
My main focus for the first half of this year is the design of interaction strategies for an interactive TV application - the notable issues with the TV interaction is the (i) lean-back (as opposed to lean-forward) attitude of the viewer both physically and mentally, (ii) use of remote control, and (iii) enjoyment as usability priority. A number of design implications come from these issues, and I am conducting a comprehensive literature review, exploring design space, sketching ideas, and designing concrete interfaces. Interesting aspect is the way usual design guidelines for Web and desktop GUI design do not apply to TV... we cannot put conventional GUI widgets - no more slider bars, no more radio buttons, no more scroll bar, no more sophisticated visualisation schemes... the trick is in the extreme simplicity and flat menu hierarchy, no text blocks, and curved lines and less saturated colours (straight vertical and horizontal lines with strong, bright, saturated colours can cause screen distortion on TV).

Attended a workshop 'Funding Available to Contract Researchers and How to Get It!', DCU (28 February)
I attended the workshop to get better idea on available funding schemes for contract researchers as myself.
