Submission + - Machine Learning allows actors to create games that understand body language (gold.ac.uk)

ptresset writes: Goldsmiths college developing technology with natural responses to human interaction. The technology enables video games characters to move in a more natural way, responding to the player’s own body language rather than mathematical rules. The hypothesis is that the actors’ artistic understanding of human behaviour will bring an individuality, subtlety and nuance to the character that it would be difficult to create in hand authored models.

Submission + - Patrick Tresset's robots draw faces and doodle whe (wired.co.uk)

ptresset writes: "Pop along to the Tenderpixel art space in Soho this month, and you could grab a drawing of your mug, sketched by one of Patrick Tresset's robotic arms.

The sketching bot is called Paul. It starts off the exhibition by scanning the room and looking for people with its motorised eye. When it spots a human face, it uses an edge detection technique called Gabor filter (which is modeled after cells in a human's visual cortex) to pick out the salient lines."

Well I would have to use randomness in the software...I don't like using random number generators... It's more fun to play with an arm...and I get 7000 hits on youtube...;) And the next step is to use visual feedback to help motor_control...that wouldn't not work with the plotter.... At this stage the point of using an arm is not obvious..I only started developping the arm since november. Ho Yes..the point is not to do efficiently beautiful drawings...;) Frankly my motivation is to pass time in an interesting manner (I shouldn't say that) Best

I thought I answered... These servos are great...and so cheap.. About the software. It is very rudimentary..I needed something to show at the exhibition. It looks around, locates a face (opencv's haar detector and/or skin colour) Moves the camera to center the face. Locates eyes, mouth. Vertical/horizontal axis The drawing is based on the responses from Gabor filters (http://www.cs.rug.nl/~imaging/)(best approximations of simple cells in early visual cortex (V1))) at various scales and limited orientations... The issue is not the feature detection..but the drawing activity in itself. The next step will be for the system to look at what it is drawing.... Best

Sure!!! you would have been happy to work on the assembly line.... I was an artist amongst thousands unable to live from my work.... I am more concerned about the use (present/near future) of robots in warfare, than of robots doing doodles... You are going to see more and more robots, you better get used to it.

If you look at the Galleries on the site ..you will see the results of an algorithm performing a representation based on gray levels (shades).. "Prettiness" is not the aim of this system... In an art gallery prettiness doesn't really qualify what is exhibited... Best
