IM Blanky

(soft) Hardware:
The blanket measures 7’7” x 4’2” and comprises 104 tilt sensors. They are arrayed in a hexa-grid formation and distributed uniformly over its entire field. The flower-like sensors consist of 6 conductive petal-like pads, radiating from a conductive tassel attached to a powered double-arabesque of conductive wire. The resistance in the current flowing through petal and tassel varies depending on which petal is in contact with the tassel (The R (Ohms) value thus indexes the direction of the tassel). The flowers are arranged in 16 clusters and their stems connected to computational node (Multiplexer). The nodes communicate the fluctuation in current resistance recorded at each flower to a microcontroller stitched to the back of the blanket (Arduino LilyPad). The data is communicated wirelessly to a computer (XBee Shield)

Software
Each flower occupies a hexagonal cell, surrounded by six neighbors. The computation script extrapolates directional vectors from current resistance data and models a slope based on the orientation of that cell in relation to that of its immediate 6 neighbors. The algorithm generates a field of peaks and valleys that gets fine-tuned into a smooth polygonal mesh by negotiating local conditions at each cluster within the behavior parameters of the overall figure (Processing).
