I am a complete beginner with MAX MSP/Jitter, Ive done a load of basic tutorials but other than that I have very little experience.

I am attempting to create a sort of prototype for an idea I have for an interactive wall surface. The surface will respond to degrees of proximity of people moving infront of it with a display of colour.

For the prototype I have an Arduino board and am attempting to use that as a method of collecting the information from the sensors (im not yet sure what the sensors should be).

With that information I want to create a real-time, dynamic animation (Jitter?) which simulates the sort of patterns of colour which would be projected onto the wall surface.

The colour pattern will be a series of squares who's colour and intensity is directly related to the proximity of a person.

Of course this prototype will be a scaled-down example of the wall surface, and the effect can be demonstrated by simply moving your hand over the sensors on the Arduino Board

1. What would be the best sensors to use for this? LDRs? How many? Any information on how to set this up on the Arduino would be great

2. How to I interpret that info in order to create the visualization?

Any help is much appreciated, and I hope I have made some sort of sense!

Your two main questions would be better posted on the Arduino forums.

i am currently making something similar to your idea for my final year degree project, i am using distance sensors on a large painting to play sounds in relation to the proximity of people who are looking at the painting.

im quite new to all this max msp and arduino stuff but i been asking plenty questions online over the past months and as regards sensors i have gone for the maxsonar ez4 which are about 25 quid each from active-robots.com, they can detect people up to 6.5 meters, which is what im after

i have been using the arduino2max patch from the arduino site :

http://www.arduino.cc/playground/Interfacing/MaxMSP

and it seems to work pretty well when i incorporate it into my max patch

so far i have managed to wire up six sensors into the arduino and then send the readings into max msp and it seems to work ok so far, though i have a lot of tweaking to do. to interpret the information that comes in is just up to your imagination and what you know and can find out about maxmsp, its just numbers

if i can be of any more assistance then get in touch, i been asking plenty questions recently so its nice to be able to give something back

I can understand that the first question is probably more Arduino-based, but surely once the information is inside the computer, the interpretation and display of it is a MAX MSP/Jitter question?

Thanks alot for that slatepipe, it could be useful, I will check out those sensors and get back to you.

as said above, once the sensor is transformed into data you can do what you

want with it.
