ShiftLens Makes Turns 3D-Printed Objects Into Smart Displays — No Electronics Required
Researchers at the Massachusetts Institute of Technology (MIT), the Technical University of Munich, and Northeastern University have combined lenticular optics with 3D printing to produce electronics-free objects that can change their appearance on-demand — even letting you know if you're using them incorrectly: ShiftLens.
"Interactive objects often rely on embedded electronics for dynamic surface appearance, which can increase fabrication complexity and reduce robustness in everyday settings," the team explains of the problem it set out to solve. "We present ShiftLens, a design and fabrication system for creating 3D objects with mechanically switchable surface appearances, enabling dynamic visual output without electronics. This allows objects to display distinct, high-resolution appearances that are discrete."
"With our system," adds lead author Yunyi Zhu, a graduate student in the MIT Department of Electrical Engineering and Computer Science, of exactly what that means in real-world terms, "an object can tell you whether you are using it...
