In response to a coursebrief on the design of experimental, sensory input-based applicationsfor the iPad, I conducted 3 experiments in Adobe Flash Builder 4.5with Actionscript 3 and Flex, using the 3-dimensional axis of theaccelerometer, and multi-touch functionality.
The first experimentwas a game in which random points on the 3 axes were chosen, withgraphical queues prompting the user to use the accelerometer to alignand reposition themselves in order to score points. Gameplay wasenhanced by making the player race against a timer and complete thistask before losing a point.
The second experimentmapped the hue, saturation, and brightness of the colour spectrum tothe positions of the accelerometer. In effect, the colours pulse tocreate a strobe effect, where the pulse rate is effected by theuser's current x and y position on the touch screen.
The third experimentwas a painting app in which up to 10 fingers can be used to create apaint drip effect with different brush options. Interaction is basedon a user touching the canvas to make small paint dots appear. Usingaccelerometer data gathered when the user rolls, tilts or pitches theiPad, the dots then animate to dynamically create visualbrush-strokes.
