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.
