Project
RemindMe
A compact physical reminder object that turns leaving-home routines into a tactile, reassuring checklist.
Brief / Challenges
Context, constraints and the design question.
RemindMe started from a common everyday situation: leaving home while distracted, rushed or interrupted. In these moments, remembering essential items often becomes a fragile mental checklist that can easily be lost.
The challenge was to translate this invisible cognitive load into a physical interaction. Instead of using a screen or a phone notification, the project explores how light, sound and tactile feedback can make the check faster, clearer and more reassuring.
The prototype also had to respond to specific constraints: it had to fit inside a 15 × 15 cm object, integrate an Arduino-based electronic system, and remain intuitive for a broad target group.
How can a physical object reduce the uncertainty of forgetting essential items before leaving home?
The Process
A concise view of how the project took shape.
The project was developed through a short five-day prototyping sprint, moving from problem framing to electronic integration, physical fabrication and final testing.
The process focused on three main layers: defining the leaving-home ritual, building the interaction system with sensors, buttons, LEDs and audio feedback, and designing a compact object able to contain all components while remaining clear and approachable.
The Outcome
Final direction, delivery and visual output.
The final outcome is a working physical prototype that supports the user before leaving home. When someone approaches the object, RemindMe activates through a proximity sensor, lights up and plays a short audio prompt.
Four illuminated buttons represent essential items. At the beginning of the interaction they appear as unconfirmed; once pressed, they change state to show that the item has been checked. When all items are confirmed, the object provides a final feedback message and returns to idle after a short timeout.
The gallery shows the final prototype, its light states and the main interaction moments, highlighting how the object combines physical presence, visual feedback and sound into a simple domestic routine.
