Spherical Interaction for Public Spaces (SIPS): EPSRC First Grant Scheme

The SIPS project will design and evaluate interactions on spherical displays in public spaces.

The SIPS project will design and evaluate interactions on spherical displays in public spaces.

It’s an exciting time for public and performative interaction at Glasgow University.  My first EPSRC grant has been funded, the announcement is available now on the EPSRC website.

So watch this space, this grant begins August 1st!

Grant Overview:  Public interactive displays have the potential to significantly enhance the quality of life for people living in future city spaces. However, current public displays and interfaces go unnoticed or completely ignored by the majority of passers-by. This presents a serious problem for the impact and uptake of touch sensitive displays if only a small minority will approach these displays and discover their interactive qualities. Existing approaches to designing and evaluating public displays have not been successful at realising the substantial opportunities that public displays afford. This research addresses this problem by exploiting recent technological developments in curved displays to create socially acceptable and enticing interactions for public spaces.

Curved displays offer exciting opportunities for public interaction that are not possible with flat displays. For example, a cylindrical display mimics the shape and form traditional kiosks for flyers and notices that can be seen in many cities. This kind of display can be placed in a walkway and be viewed from many perspectives. Other non-flat shapes, such as spherical displays, allow multiple users to interact while facing each other and viewing vertical content. Installations where users can see each other and observe others interacting are more encouraging and result in higher rates of interaction than displays where users are unable to observe each other. Another important aspect of a spherical display is that the entire display is never completely visible from one perspective. While areas on the top may be visible to both users vertical areas of the screen are only visible to some. These “private” areas of the display could be exploited to support sharing, ownership, and collaboration on a social display.

Given the new opportunities afforded by curved displays, foundational research is needed to understand how this new technology should be designed for and used in public spaces. There is limited research on interaction for curved surfaces and even less on curved surfaces for public spaces. An important aspect of this research is to develop novel multitouch interaction techniques that exploit the form factor of a curved display for public interaction. This will involve perceptual studies to learn the physical constraints and ergonomics of multitouch gestures on curved surfaces. This research will also explore how novel gestures and physical metaphors can enhance interaction on curved surfaces. This will involve evaluating user perceptions of control and responsiveness on a spherical display, simulating different levels of friction and weight for interactive elements.

Another important aspect of this research involves how curved displays work in real public spaces as compared to flat displays. Little is known about how different interaction styles encourage or discourage continued use of flat or curved public displays. In order to measure these metrics at scale for large numbers of passers-by, new evaluation techniques are needed. This project introduces a novel evaluation technique to capture and analyse pedestrian traffic around public installations. This approach can quantify different metrics of public display usage and enable the collection of large-scale data sets not feasible with traditional observation methods.

Finally, this research also aims to dramatically change the approach to designing public displays by considering context and impact on local spaces. Previous work on public displays has primarily involved flat displays and focused on making displays as noticeable and enticing as possible. This presents the possibility of creating unnecessary or unpleasant distraction and actually making public spaces less enjoyable places to be. This research will not only measure how enticing our displays are but also critically analyse the impact of these displays on the places where they are deployed.

Celtic Connections Installation with Pufferfish Ltd

1016359_10102296579687751_325721798_nAs part of my current project, I am working with Pufferfish Ltd to evaluate spherical displays in public spaces.  One of our exciting installations combines my research and my love of Scottish music.  We’re working with Celtic Connections to install the PufferSphere display in the concert hall for the whole opening weekend of the festival.  It’s an exciting place to be and also my first public engagement since starting my SICSA Fellowship.  It’s been a wild ride but we’ve pulled it off with style.

The official news item…

Computer scientists plan to make Celtic Connection with global project

Visitors to the 21st Celtic Connections festival will have the chance to hold the world in their hands at Glasgow Royal Concert Hall from today (Thursday 16 January).

Researchers from the University of Glasgow’s School of Computing Science have teamed up with Edinburgh-based display developer Pufferfish Ltd to create an eye-catching illuminated globe which will provide information on 25 of the festival’s top acts.

A computer-controlled display will project a high-resolution image of a world map onto the 600-mm spherical display’s touch-sensitive surface. Users can ‘spin’ the image, which is marked with the locations of artists’ home cities, and tap on artists’ names to find out more about their work and festival gigs.

In addition to providing an unusual source of useful information to Concert Hall visitors, a set of small cameras placed around the display will provide the research team with feedback on their reactions.

Research associate Dr Julie Williamson, who led the project, said: “This is the result of four months of work to develop the content to show on the PufferSphere display and determine how we could best measure visitors’ responses.

“We’re really interested in finding out more about how technology influences pedestrian traffic in public spaces, a process we call performative interaction. We want to know how long people spend at the display and whether they use it alone or in groups. We wanted to get involved with Celtic Connections because it attracts so many visitors from around the world and we were delighted when they agreed to help.

“We’re planning to continue our research with another public display at the University campus next month.”

Dr Williamson worked on the project with product designer Daniel Sundén and Pufferfish Ltd’s software manager Dr Jay Bradley and sales and marketing manager Ben Allan.

An Unusual Training Session

2013-04-27 11.04.40 In my effort to keep up my training during CHI 2013, I completed my long run today along the Seine River. Accidentally ran into a few landmarks along the way. I started near the conference center going towards to the Arc de Triomphe.





2013-04-27 11.11.50

From there I headed down Champs-Élysées. The was the best part of the run because it was a gentle downhill slope the whole way.







2013-04-27 11.25.51

Caught a glimpse of the Eiffel Tower from the other side of the water.  Notice the lovely springtime weather in Paris this week.






2013-04-27 11.48.08

Crossed over the water along “lover’s bridge” at the 4 mile point but forgot maths and and geometry and headed in a triangular trail which would end up being more than 8 miles (I had just completed the hypotenuse of my run).





2013-04-27 12.20.02 Took a victory lap around the base of the Eiffel tower and headed home thinking of lunch! Ended up being roughly 10 miles all told, at a terrible pace due to the constant stopping/starting for traffic and sightseeing.  But it was important to just get out there and run!

This training is all going towards the half marathon in Edinburgh this May.  I’m running the half in memory of my mother for the Bowl Cancer UK Charity.  Donate and become part of an excellent cause!
