DESCRIPTION:Space is an important cognitive resource. During epistemic act
 ivities\, people lay out information in space and scale to externalize and
  spatially reflect their current thoughts\, or to provide a shared space f
 or in-group discussion. This behavior is documented for many activities\, 
 for example for sensemaking and analysis of data\, ideation in creative de
 sign\, or general practices of knowledge work. Especially for knowledge wo
 rk\, "lay out documents in space for reading\, in order to read and write 
 across documents is crucial" (Sellen and Harper\, 2001).\n \nIn the first 
 part of this talk\, I show how egocentric physical navigation improves nav
 igation performance and long-term spatial memory when navigating virtual i
 nformation spaces. In subsequent work\, I also looked at the display size 
 for peephole navigation and I discuss the "sweet spot" between display siz
 e and both user navigation performance and user task load and share my ins
 ights about the design of peephole map navigation.\n \nIn the second part\
 , I talk about HuddleLamp\, which enables spatially-aware interaction by t
 racking multiple mobile devices on a table using a low-cost RGB-D camera. 
 I describe its underlying technology and algorithm and also report how we 
 used this to elicit user-defined cross-device gestures for an analytical s
 ensemaking task. I discuss results of our two-phased user study\, which ca
 n inform the design of future mobile cross-device interaction.\n \nThis ta
 lk is based on joint work with Hans-Christian Jetter (UCL)\, Nicolai Marqu
 ardt (UCL)\, Harald Reiterer (University of Konstanz)\, and Yvonne Rogers 
 (UCL).\n\n(Sellen and Harper\, 2001) Sellen\, A. J.\, & Harper\, R. H. R.
