Projects

Biographical and Personalized Cognitive Stimulation

We explore how biographical information can improve cognitive stimulation and design interactive platforms to support people with dementia, clinicians, and families.

Clinical Assessemnt using Datapark

Data-Driven Healthcare

Our goal is to increase and improve the information clinicians and patients have access. We explore and develop mechanisms for collecting, processing, and analyzing the data. We also have a huge concern on how the information is presented.

Personalized Digital Interventions

We seek to tailor and personalize digital interventions to increase users motivation and adherence to the interventions. To this end, is crucial to gather a deep understanding of the intervention, context of use, benefits and difficulties associated and to accede to the mental models (goals, needs, motivations, etc) of the users.

Personalization of User Interfaces

We explore solutions to increase the agency of individual users over the interfaces they use.
