Designed in a Physical computing foundation course, the Memo Doormat is a tangible interface that reminds you of your obligations when you’re leaving home.
The intention of this project is to oppose the fact that we keep forgetting objects or tasks when leaving our places. To remedy this, the Memo Doormat vibrates while you step on it, giving you a pause and your mind a chance to make sure it didn’t forget anything.
In the design process, at first I tried to find a way to display a specific task directly on the doormat. It was only until after I saw that few people actually look at their doormats that I decided to make it vibrate instead.
Additionally, after integrating three vibration motors, I was able to implement different vibration patterns and experiment how they are perceived by users.
The prototype is controlled by a custom-designed PCB based on Arduino and designed with Fritzing.
