Together in Shape (TIS) is a Co-responsibility system that supports bariatric patients and their partners in achieving bariatric lifestyle changes. The system was co-created by Philips and Catharina Hospital. When designing this intelligent system, the team applied the Data-enabled Design process. TIS uses a carefully selected set of data trackers to provide the most complete possible overview of its users’ lifestyle. This is achieved by collecting behavioral, contextual, experiential and clinical data from the bariatric patients and their partners. Healthcare Professionals (HCPs) are kept up to date via a dashboard. The system can deliver lifestyle advice to the bariatric patient and their partner both based on its pre-programmed parameters and the HCPs can also trigger custom advice.

Who is the target audience and why design for them? We designed Together in Shape (TIS) for (bariatric) patients, their partners, and their healthcare professionals. The success of sustained weight-loss after bariatric surgery varies per patient and is known to depend largely on a patient’s ability to adopt a healthier lifestyle. Therefore, designers specialized in the healthcare domain, and interested in behavior change are the main target audience for our demo. When designing TIS we applied the Data-enabled Design process. Therefore, we invite all designers interested in data and Artificial Intelligence to have a look at our demo as well!

What were the challenges or limitations encountered in this project? We have encountered many challenges and limitations. In order to test out the system we ran a clinical trial with six participating families. Due to the strict privacy, security and clinical regulations our freedom as designers was limited. Moreover, this innovation was produced in collaboration with educational, clinical and industrial partners. Managing all stakeholders was not an easy task the team had to overcome.

What are the opportunities and next steps for this project? The current Together in Shape (TIS) system is limited in the kind of data it can understand. We would like to further explore how to measure experiences, like a zoomed in view about the relationship between its users, the patient and the partner. When building the system we have many times relied on Wizard of Oz prototyping, therefore we would like to further explore the way to further automate many parts of the system in a feasible, sustainable way.
