DIY HACK - HOWTO sense Squeeze!2

Ohhh….. here’s a really cool DIY HACK that can sense your squeeze. (This might be good for making an adult-related game…then again…)

I’m researching squeeze sensing as a mode of tactile interface. Here I will cover the process of developing a squeezeable sensor and the firmware/software concerns associated with interpreting the data from the sensor. This fulfills the “sensor project” for my class called Computational Principles in Media Arts taught in AME at ASU by Todd Ingalls and Hari Sundaram.

First off, how do we sense “squeeze?” People squeeze all kinds of things: lemons, steering wheels, loved ones, toothpaste and other toiletries, pimples, stress balls, hand exercisers. I would like to focus on the latter two, which provide a therapeutic activity for those with Repetitive Strain Injury (RSI). Using flex sensors arranged in a certain pattern on a spherical object, in this case a rubber dog toy, one can capture whenever the ball is squeezed. Here’s a sketch of the sensor layout:

    I can sense a market for it in physiotherapy. Gripping a hard rubber ball is a therapy for recovery from loss of strength in the forearms. With a sensor, progress can be monitored and act as a motivator.

    Oh, great idea, someone will come up with that soon to the market…
