'Frame' is an interactive store display concept that helps customers make a choice by offering suggestions based on the behaviour of previous customers. When a pair of glasses is picked up, three other pairs of glasses will be highlighted to guide the customers in their choice. This project was part for the course Interactive Technology Design at the Industrial Design Engineering faculty at the Technical University Delft. The final working prototype uses a combination of  Arduino + Processing + PHP (OpenSlopeOne) + MySql to record behaviour and serve recommendations. It was done in collaboration with other students, our group was called 'things3'.
