Steven Strachan - Dynamics and InteractionPresentation Transcript
Dynamics and Interaction Steven Strachan, Roderick Murray-Smith Hamilton Institute, NUI Maynooth & Department of Computing Science, University of Glasgow [email_address] http://www.dcs.gla.ac.uk/~rod http://www.dcs.gla.ac.uk/~rod/Videos.html With John Williamson, Parisa Eslambolchilar, Andy Crossan, Vuokko Lantz, James Kelly, Stephen Brewster, Andrew Ramsay May 2007
Dynamics & Interaction group
Led by Roderick Murray-Smith
Two-campus group. Based in The Hamilton Institute & The University of Glasgow
Dr Murray-Smith spent 7 years at Daimler-Benz research in Berlin, followed by M.I.T. and Technical University of Denmark.
Exploring the overlap between control theory, machine learning, probabilistic reasoning and human-computer interaction design.
Leading group in novel forms of interaction design for mobile interaction. Act as consultants for Nokia, Samsung and Microsoft.

Control in HCI?
More and more devices are incorporating inertial sensing…
What new kinds of interface can we develop with this new sensing capability?
Think of user and device as being in a loop of control…
From ‘look-and-feel’ to ‘ handling qualities’?
Moving from discrete event -based systems like this:
To continuous control like this?
Dynamics & Statistics in HCI?
Why introduce dynamics – is that not harder?
We can only control what we can perceive .
Dependent on feedback, so upper limits on the speed of change of display.
Large steps in entropy are unnatural & error-prone
Dynamics allows us to slip in ‘intelligence’ which couldn’t be done with a static interaction technique
Why uncertain interaction?
Uncertainty in user’s mind about what to do next, and system uncertain about user’s intentions.
With mobile devices, interaction with the user is now continuous instead of discrete, and input devices are noisier.
‘ Honest’ interfaces
Can lead to smoother interaction, with user behaviour regularised appropriately (e.g. K ö rding & Wolpert)
Mobile Sensing: MESH hardware description
Built by MLE Palpable Machines group.
Modality Enhancing Sensor-pack for Handhelds
Designed for the IPAQ range of pocket PCs
Physical design same as the PCMCIA expansion jacket
