Changing the Appearance of Physical Interfaces Through Controlled Transparency

Explore a groundbreaking 22-minute conference talk from the ACM Symposium on User Interface Software and Technology that introduces physical interfaces capable of changing their appearance through controlled transparency. Delve into the innovative concept of transparency-controlled physical interfaces, ideal for ambient display scenarios where optical communication suffices. Discover how these interfaces rapidly transition between perceived shapes without mechanical parts, consuming minimal energy. Learn about the construction of 3D physical interfaces with individually controllable components using laser-cut and folded transparency-controlled material. Examine the unique benefits of this technology, including the creation of apparent holes and object nesting. Gain insights into the design space of transparency-controlled physical interfaces through four physical prototypes: two activity indicators, a playful avatar, and a dynamic lamp shade. Understand how this approach complements existing shape-changing interfaces, offering new possibilities in user interface design and ambient communication.
