Trying out different ways of creating movement mechanically. In order to use servos, I need to transform circular motion into linear motion to push up at the ball from the inside. After failing to create a desirable movement with wooden beads, I began to look at making an umbrella-like construction. I also tried using muscle wire (a thin flexible wire which shrinks when current passes through and then returns to its original state) which turned out to be difficult to control and also to make quicker or larger movements. | Trying out different ways of creating movement mechanically.

I also added 'trigger' points to my eye tracking programme which each set off a different servo motor whenever an eye is tracked at that position. This involved setting up a serial port communication between Arduino and Processing. | |||
