Project Overview

We envision Fluxa as a transient wearable display to foster richer self-expression and communication in daily life . Fluxa is an wearable device (LED array) utilizes POV(Persistence of Vision) to display light effects while moving.

When the user moves his/her limb, Fluxa displays a pattern that, due to retinal afterimage, can be perceived by the surrounding people. It can be used to enhance existing social gestures such as handwaving to get attention, as a communicative tool that displays the speed and distance covered by joggers, and as a decoration device that generates images around dancing bodies. We used Arduino and Adafruit LEDs as the hardware, and sewed them on a glove. The LED will blink each frame, representing each column of the image. Gyometer was used to determine the waving speed and direction. We also built an iOS control application.
