ReJAM Project

The ReJAM project aims to develop Robots engaging elderly in Joint Activities with Music. It is a cooperation project between TNO and the Delft University of Technology. The objective of ReJAM is the promotion of physical, cognitive, emotional, and social wellbeing through various music-related activities, e.g. physical exercises, games, reminiscence, and making music together. The activities are designed especially for group activities: ReJAM is well-suited for use in meeting centers or together with visitors at home.

Research indicates that music can have positive effects on people with dementia: it relaxes people, helps them during reminiscence, lifts their spirit and mood, and stimulates social connectedness. An important challenge is to personalise the music, the activities, and the interactions, while keeping the demands placed on caregivers at a low level. We have developed a list of requirements and envisioned interactions that together provide a blueprint for a system that fits the demands, needs, desires, values, and living environment of people with dementia. This blueprint is captured in the ReJAM project and will be developed and implemented further over the next 4-5 years. 

The Socio-Cognitive Engineering (SCE) method and tool are being applied to support (1) the human-centered research and development process, (2) the collaboration between project partners, and 3) the sharing of project outcomes for further application or development, See the Wiki SCE tool (WiSCE) tool for some examples.

Current experiment:

For his MSc study at TU Delft, Bernd Kreynen has developed a first prototype for music-based emotion regulation. The envisioned application centers on  people with dementia. However, the technology can also be applied for other application areas and needs to be tested thoroughly. When you are interested, you can easily participate in the first experiment. This experiment consists of listening to 4 songs; it can be completed online through the website On the website you can find more information about the experiment itself, so if you're interested have a look!
