Researchers of the Parreha (PARkinsonians REHAbilitation) project have developed glasses which use virtual imagery to help people with Parkinson’s disease cope with walking problems.

Some people with the disease suffer from freezing, which renders them unable to move once they stop. But they can be prompted to start walking if objects are placed in their way and they have to walk round them.

The headset works by producing visual clues, with lights from the headset creating a tunnel-effect, which enables users to focus on the virtual imagery and move more freely.
