Immaterials: Light painting WiFi Written by Einar Sneve Martinussen Tuesday, 22 February , 2011 ImmaterialsNetworked cityVisualisationWiFi Related posts: Making ‘Immaterials: Light painting WiFi’ The city is filled with an invisible landscape of networks that is becoming an interwoven part of daily life. WiFi networks and increasingly sophisticated mobile phones are starting to influence how urban environments are experienced and understood. We want to explore and reveal what the immaterial terrain of WiFi looks like and how it relates to the city.
I was thinking about doing something like this but with relative humidity.
Somehow last week I was speaking to someone about our vision and specifically what we can't see, and how it would be cool to be able to visualise the relative humidity distribution across a space, like inside an entertainment centre area or somewhere like that.
Ultimately though we can only view 2D projections of a 3D space, so I'm not sure how you could even visualise humidity - you need to know at what depth. Maybe you could work out the depth of your focus, then provide the humidity projection info from that.
Hey pinky - you know even if you can only "see" 2d, you can represent another dimension by using different colours..
Like say with that guy how he did his thing was he had 1 pole, and that pole only had 1 wifi receiver and 20 lights. That means between the access point and that receiver (where ever it was on the stick) those colours were being lit up, using a whole dimensions just to show where the reception was at 1 point in space.
But - if he instead had 20 receivers on that stick, and 1 light for each of them, say from green to red - green for good and red for bad you'd find yourself seeing at least 2 dimensions, meaning you can start extrapolating things from there anyway because you can see hotspots and cold spots for wireless reception, as he went past a car for example the wireless would probably get redder on only the parts which would be obstructed (don't have line of sight to the AP).
That would be really cool, especially if you went around and did long exposure like he did, and had a full (i want to say topology but that's wrong) wireless reception map. It'd almost be useful instead of just cool.
Anyway don't know how it'd solve your 3d over 2d directly - but if you can show something already in 2d then perhaps think about using something like colour (or time) to show another dimension.
