The document describes Jessica Floeh's concept for an art installation called "Moody". [1] Moody would be an interface that uses colored lights to provide feedback on a person's energy based on how they hold it, [2] striving to investigate how a perceived biofeedback device impacts self-perception. Precedents discussed use sensors to interpret emotional states and ambient spaces. A prototype used a fake biometric sensor and button to cycle lights and interpret personality, but lacked legitimacy. Moody aims to have a less sterile, more playful design to subtly influence how people view their own energy.
