Translate color to smell with Bouquet

by Larra Morris

Hope springs eternal for Smell-O-Vision. [Niklas Roy] recently taught a workshop called Communication Devices at ÉCAL in Lausanne, Switzerland. Four of his Media & Interaction Design students built a scanner that detects colors and emits a corresponding scent.

The project consists of an Arduino connected to a color sensor as well as a SparkFun EasyDriver. The EasyDriver controls a stepper motor which rotates a disc of scent swatches so you sniff the swatch corresponding with the color. The students chose strawberry for red, and blue ended up being “ocean”-scented room spray.

Want early design analysis without simulation?

Traditional verification methods are failing today's complex IC designs, which require a proactive, early-stage analysis approach. A shift-left methodology addresses IP block integration challenges and the limitations of traditional simulation and ERC tools. Insight Analyzer detects hard-to-find leakage issues across power domains, enabling early analysis without full simulation. Identify inefficiencies earlier to reduce rework, improve reliability, and enhance power performance.
