The Body as Input
I've been playing around with how the body can be used as an input device for digital interfaces, as opposed to the usual keyboard/mouse type of inputs.
Some experiments included making letters with the body and using that to type on screen, or using movements like head position and sound to alter shapes on the screen.
One interested thing that I've been thinking about is how to make these bodily inputs intuitive. An experiment I made was a sketch that adjusts how tall a rectangle is depending on how high your face is in relation to the screen. The intuitive action of moving your face up or down to adjust a variable is one way in which the body can be used to create new forms of interesting inputs that are intuitive and not abnormal or unnatural.
