The research is part of Live Science, an ongoing project where scientists go into the Science Museum to carry out research using museum visitors as volunteers.
With the help of their students, Dr Jo Van Herwegen, Dr Elisa Back and Dr Sabira Mannan ask visitors to copy patterns illustrated in a book using 3D plastic red and white cubes, while their eye movements are tracked using a Tobii Glasses Eye Tracker. On their first day they had more than 100 visitors and collected data from 39 people. Anyone is welcome to take part and the researchers are particularly keen to encourage children aged six to eight.
Back at the University, the researchers analyse the video using a millisecond-by-millisecond analysis software programme. They can, for example, determine whether the person completing the test was looking at the pattern they were asked to copy, or their own cubes, or were distracted and looking at something completely different. The researchers hope to learn how our visuo-spatial abilities develop as we grow older, and how to improve visuo-spatial performance.
The video below shows Dr Van Herwegen using Tobii eye tracking technology in an unrelated study to track the eye movements of babies in her lab:
Some people have difficulties with their visuo-spatial abilities, and this can have a big impact on their lives, especially their levels of independency. Developing a better understanding of why some people have better visuo-spatial abilities than others could lead to better interventions and training programmes.
