Sense Stage Workshop

I have made some extra nodes to deal with the data from the paper pressure pads, based on the investigations two groups made of figuring out which pad is which this morning.

First the paper sensor data is scaled from 0 to 255 (nodes 120-127) to a range between 0 and 1 (nodes 220-227).

Zone 1 consists of “paper1″ (220), “paper3″ (222), “paper4″ (223) and “paper8″ (227).
Node 230 remaps this data per node.
Node 240 remaps the data in a 4 by 6 grid.
Node 250 gives a weighted coordinate within the paper sensor in a x and y coordinate; this is a measure of the center of gravity within the zone.

Nodes 231, 241 and 251 give similar data, for zone 2, consisting of “paper5″ (224), “paper6″ (225) and “paper7″ (226).

I have yet to take into account the min-max ranges that Matt measured.

We will be using a number of pressure sensors made of 3 layers of conductive paper. These sensor act as force resistive sensors (FSRs). We have made them in tiles with each 4 sensitive pads, to be laid out on the floor.
