Could you be the missing part of the puzzle and help dementia researchers, unlock information about behaviour and dementia for future generations? BRACE works closely with Dr James Selwood, who is appealing for volunteers for the CUBOId project.  You can find out more about this exciting project and how to volunteer below. 

CUBOId: Using new technologies to measure behaviour in a home setting

There is a pressing need for finding new ways of making an accurate, early diagnosis of dementia. Subtle behavioural changes may occur in people who go on to develop dementia. Researchers at the University of Bristol have developed state of the art technology (known as SPHERE) that enables us to monitor these changes in peoples’ homes. The aim of the CUBOId project is to determine whether this home sensor technology can be used to identify early behaviour patterns that may suggest a diagnosis of cognitive decline or dementia.

The CUBOId project is looking for participants who have a diagnosis of mild cognitive impairment (MCI) or Alzheimer’s disease. We are aiming for the SPHERE system to collect data over a period of 12 months and we will compare this with conventional memory tests that are done in the clinic. The data are collected in three ways:

  1. A wristband to collect data about daily movements.
  2. Sensors are installed around the home to collect data about daily activities, such as electricity/water use and cooking.
  3. Silhouette sensors to collect data about behaviour around the home, such as looking for misplaced items. These are installed only in communal areas.

These are examples of the SPHERE equipment used. The picture on the left shows the different parts of the wristband. The picture on the right shows the interior of one of the SPHERE sensors that is installed around the home.

These are examples of the silhouette images captured by the SPHERE system. These images show a resident cooking in a house that has been fitted with the SPHERE technology.


The CUBOId study is funded by the Medical Research Council with support from the Bristol-based dementia charity BRACE. The Chief Investigator is Professor Yoav Ben-Shlomo (Population Health Sciences, University of Bristol). The study has received ethical approval from Carmarthen Research Ethics Committee.
