Abstract

In this paper we present ShadowLamp, a lamp concept supporting controllable shadow casting for displaying ambient information. The concept uses electrochromic displays to mask light and thereby allow switching of projected shadows. We implemented a prototype in a hexagon frame with six separately controlled LEDs compartmentalized to casts shadows in 60° angles. Alongside the LEDs, each compartment contains an electrochromic display for shadow control. As a use case we fabricated displays for a children’s book and used them to change the shadows as the story progress. The displays and LEDs are controlled by a Bluetooth connected Android application.
