Espresso Cup

The Espresso Cup is a tangible artifact to analyse the user’s drinking behaviour through data mining methods. The Espresso Cup is a further development of the SmartMug by Joschka Sondhof and focuses on the daily user’s coffee consumption in home automation environments, such as the Living Place Lab. The Living Place lab provides a ‘real world’ context to investigate ubiquitous computing systems and enables the Espresso Cup to connect with other systems in the lab and to create a personal user profile.

To track the drinking behavior, the Espresso Cup uses the ESP32 microcontroller and a 9DOF BNO055 sensor on an in-house developed printed circuit board (PCB). The PCB can be used for various applications, designed and implemented by Markus Kasten. When the Espresso Cup gathers data, a neo pixel LED lights up to provide a user’s feedback.

The Espresso Cup design consists of a glass mug for the coffee and a 3D printed model to store the hardware, which can be easy removed from the glass mug. The 3D model was constructed in the CAD software Fusion 360° and printed with stereolithography technology.
