Bristol Interaction and Graphics is united by a common interest in creative interdisciplinarity. We act as a hub for collaboration between social scientists, artists, scientists and engineers to combine efficient and aesthetic design. We are particularly interested in areas which couple the design of devices with deployment and evaluation in public settings. Members of the group have expertise in research areas spanning human-computer interaction, visual and tactile perception, imaging, visualisation and computer-supported collaboration.

Kirsten promotes Innovation & Entrepreneurship on CNN

When asked ‘is entrepreneurship actually something that you can teach?’ Dr. Kirsten Cater, Academic Director of Bristol University’s Centre for Innovation, tells CNN Money, the aim is to create a unique environment:


“You can teach students the skills, the tools, the techniques to become entrepreneurs. But, more importantly, you need to create the environment and the ecosystem to allow them to flourish, allow them the opportunities to fail and then learn from that failure and to also have experiences with successful entrepreneurs.”

The University of Bristol launched the Centre for Innovation and Entrepreneurship this autumn with an inaugural cohort of 55 undergraduate students, and it’s gaining international attention.

PowerShake: Power Transfer Interactions for Mobile Devices The

Tyranny of the Everyday in Mobile Video Messaging

Running out of smartphone battery could be a thing of the past, thanks to power sharing between devices.


We are pleased to announce The Economist has published an article on a paper by BIG researchers Paul Worgan, Jarrod Knibbe, Diego Martinez Plasencia and Mike Fraser.

The paper presents a power sharing concept called PowerShake. PowerShake enables users to share power across their multiple mobile devices, such as smartphones, tablets and smartwatches, using inductive power transfer. Today we are beginning to carry multiple mobile devices, though the energy is used at different rates across each of the devices, meaning one device could have near full battery and another almost no battery. PowerShake allows users to transfer energy, for example, from their tablet to their phone to support an important phone call. PowerShake also allows users to share or trade power with others, including friends, family and colleagues, on-the-go and all without charging cables.

Watch the PowerShake video for more information.


Floating Charts presented at 3DUI


BIG researcher Themis Omirou presented the paper ‘Floating Charts’ at the 3DUI conference in Greenville South Carolina. The conference was part of the IEEE Virtual Reality conference 2016 which hosted an array of interesting demos involving a variety of VR headsets and augmented reality headwear.

Subtle Interfaces Panel at SXSW

Bristol Interaction Group researcher Peter Bennett attended SXSW last week to present a panel on “Subtle Interfaces: Designing for Calm Tech” along with Verity MacintoshChloe Meineck and Tom Metcalfe. Audio recording of the panel below, with a video to follow soon.


Sonic tractor beam goes to Hollywood


Bristol Interaction Group member Asier Marzo demonstrated the world’s first sonic tractor beam to Hollywood actors Ben Stiller, Owen Wilson and Will Ferrell on the Spanish TV programme El Hormiguero.

6 Papers accepted to CHI 2016


Bristol Interaction group will present six papers at ACM CHI 2016.

Flexible On-Body Coils presented at IEEE


Themis Omirou  and Paul Worgan are presenting ‘Flexible On-Body Coils for Inductive Power Transfer to IoT Garments and Wearables’ at the IEEE World Forum on the Internet of Things in Milan.

Their paper demonstrates that on body inductive power transfer designers have the flexibility to customise their coils into aesthetic shapes, with performance in accordance with Faraday’s Law of Induction.

1st place as the Peoples’ Choice in the Art of Science Competition

BIG member Asier Marzo won the 1st place as the Peoples’ Choice in the Art of Science Competition.

The Mandelbrot set contains the points (C) that satisfy the purely mathematical condition of not escaping to infinity when iterated as (Zn+1 = Zn^2 + C).

In the picture, we present a modification of the set in which the orbits of each escaping point are drawn (Buddhabrot). Different colours are assigned depending on the amount of the iterations applied before existing a stable orbit.

Engineers and physicist use mathematics as the language to describe reality yet its foundations (ZFC core) are thought to be independent of our existence.
