Creativity and Cognition 2011

Monday, November 21st, 2011

Just back from Creativity and Cognition 2011, which was truly ace. I gave the paper I wrote with my co-supervisor, Prof. Ernest Edmonds, which people seemed to like. Saw some thought-provoking presentations and met a number of inspiring and wonderful people. Everything one could wish for in a conference, really.

Guy Claxton gave a truly thoughtful keynote. Creative-Mindedness: When Technology Helps and When It Hinders. He pointed out that formal education as it’s currently instituted systematically destroys the creative habits of mind. In response to a question on how precisely it does this, he referred to his chart of those habits. For example, one creative habit is inquisitiveness, which is damaged by the focus in structured curricula on requiring students to study questions they have not asked. Another is creative stamina & resilience (exemplified by Einstein, who said that it was not so much that he was especially clever, but more that he stayed with problems for longer). This is damaged by the scheduling of classes that require every problem to be solved in an hour.

The papers continued through the next few days – but there were also a  lot of excellent posters. Apparently as there was only a single track for papers, the organisers could not accept some submissions that were actually very good, so those people were encouraged to resubmit as posters. Which meant that the quality of work in the posters was pretty impressive.

Of course, it’s Creativity and Cognition so there was also room for art – my favourite works were Matt Ruby’s Sympathy for Pacman and Jack Stenner & Patrick LeMieux’s Open House: Interaction as Critical Reflection. To top it off, the conference was held at Atlanta’s High Museum of Art, and we were permitted an after-hours tour. As well as some tragically unmoving Calder mobiles (which really don’t belong in temperature controlled rooms), there on a wall was perhaps my favourite artwork of all time: Duchamp’s L.H.O.O.Q. Shaved. Yes, you have to know the story for this one to work properly.

So finally: a few people asked for my slides, so after the break I’ll embed a Quicktime movie of them. Thank you everyone at C&C 2011, and especially the erstwhile organisers for providing such a great atmosphere for collaboration and creativity.

Gerhard Fischer at CCS

Thursday, June 3rd, 2010

To our great delight Professor Gerhard Fischer is visiting my research group, the Creativity and Cognition Studios this afternoon, at the invitation of our own Professor Ernest Edmonds.

Earlier this morning Prof. Fischer delivered this HAIL lecture on Meta-Design and Social Creativity at the CSIRO. And as social creativity is a central research concern for many of us here, we’re quite excited to have him here.

Personally I’m hoping to talk about mixed reality and tabletop systems as opposed to immersive virtual environments for collaborative creativity at a distance. Or the role of Collaborative Place. Or whatever comes up ^_^

What I’m working on

Ad-hoc workspace sharing prototype

Tuesday, April 28th, 2009

I’ve been IKEA-hacking. There’s a great community that does this for real – do you think mine counts? I’ll explain first.

I recently posted an idea for ad-hoc workspace sharing for under $US 500/person. The idea is simple: get one of the new LED-based micro projectors, tape it to a webcam and point them at a surface. Then everything the camera sees can be projected back onto the same surface, or more interestingly to a remote setup along the same lines. Now two people at different locations can share a workspace.

When figuring out how to prototype this, I then thought of the ubiquitous angle-poise task lamp. Apparently Anglepoise is actually a brand, which I did not know – it’s the true original, designed by George Carwardine in the UK in 1934. It’s this lamp that Jac Jacobsen found in a shipment of sewing machines, licensed and redesigned in 1937, resulting in the classic Luxo L-1 luminaire. Some version of this architects’ lamp then inspired John Lasseter to animate Luxo Jr., the short film that became the spirit of Pixar.

Now, I’m going for low-cost, ad-hoc and ubiquitous. I’m not going to use a $200 Luxo L-1 or Anglepoise Original 1227. Not unless I find a new source of funding, anyway 😉 In any case, it’s more appropriate for me to use the most low-cost, ubiquitous version of this superbly functional modern design: IKEA’s TERTIAL. $18.95 from my local IKEA in Sydney, $8.99 in the US.

The height is perfect to throw a 30cm/12″ diagonal display from the 3M MPRO110 Micro Projector, and if you remove the lamp assembly the projector fits beautifully in its place, with room to spare for a webcam. Here’s my blueprint and a shot of the design in situ. If you make one too, we can try them out.

Next is to design and implement some user interaction methods. One quite nice thing is that the field of view of the camera is wider than the lightfield of the projector. This means that we can use the projected area for direct manipulation of things in the mediaspace, and use the area around it as a gestural interaction zone for anything that effects the mediaspace as a whole.
