Zach Lieberman is one of the smarts behind the openFramework software. Here he is talking about some of his projects. The main reason I have posted this video is for the project that is introduced 6mins in.Zach has been collaborating with an old school graffiti artist who goes by the name of Tempt. The twist is that Tempt now suffers from Lou Gehrig’s disease and is paralysed. Zach Lieberman and a few others created a system for tracking Tempt’s eyes and relaying the movements back to a drawing package. The accuracy is really quite amazing and the project is very inspirational.

I came across this Researcher whilst studying for my degree unfortunately for a while i forgot his name and could not find him online (found him again now.) I was really impressed with his work in manipulating data from the Wii remote and taking the basic principles of how the Wii-mote works and flipping them, twisting them and basically manipulating them to become much more creative and useful.

I am starting to get quite obsessed with procesing at the moment its a very addictive framework. I have been experimenting with the video class library. Processing allows for individual pixel comparison of each capture from a webcam. The code from the video in this post compares the current webcam capture to the previous capture from the webcam. The code scans from left to right top to bottom when it finds the first pixel that is different from the previous capture it draws a circle on the screen at that point. One of the interesting problems solved from this code was converting the linear array of pixels from the webcam capture to the 2d space on the form.

xPos = The modulous or remainder of pixelnumber / width.

yPos = the result of pixelnumber / width ignoring the remainder.

ps. ignore the quality of my very very old webcam its just impressive it still works

I have recently been looking for the best way to visualise data and make it come to life. I came across an amazing piece of software. processing 1.0 (BETA) has a very simple interface which is so similar to the arduino interface that it must have something to do with arduino. As soon as i realised the similarities i felt very at home with processing. There are so many good examples of how to use the software that i know the learning experience should be smooth and exciting. I really liked this example.

I also found some really nice examples of processing being used in the design world. Ole Kristensen produced a video entitled ‘Body Navigation’  which has some brilliant examples of how processing can manipulate what a camera sees and then project a reaction on any surface.
