Individual MSc project at TU Delft

In collaboration with Biomet Orthopedics


It was asked to define and to explore new interactions during the patients’ journey after the knee/hip replacement. The goal was to improve the patients’ experience by creating an interactive design concept that could contribute to the faster patient recovery and overall satisfaction related to the Biomet brand. 


During the user research activities I've already focused my attention in the stage of the post-op rehabilitation, when patients stay at home during the recovery period. At that moment, any patient needs a help of physiotherapist and also to deal with self-management, in order to make the recovery process safer and faster.

The field research (observation, interviews) was conducted with physicians, therapists and patients at Reinier de Graaf Hospital in Delft, and at several local rehabilitation centers. The aim was to define the needs of patients in their daily routines and to explore new interactions. 


BioCoach is a wearable sensor/actuator device used for rehabilitation purposes, which uses a Bluetooth wireless connection to return sensor data to a host, and to receive commands to initiate two different haptic stimuli, such as tapping and vibration.               

In other words, BioCoach may support patients with their self-management during physiotherapy exercises at home, when caretakers cannot support them. Therefore, It can improve a patient’s kinaesthetic experience during the physical exercises, and also can help physicians to monitor the recovery in a better way.

In addition, BioCoach design concept was recently developed by Biomet Orthopedics in collaboration with TU Delft, and, as a result, the patent was applied.
