Persistent Postural Perceptual Dizziness (visual vertigo) project

We are a team of researchers who aim to understand, diagnose and treat visual vertigo using virtual reality.

Persistent Postural Perceptual Dizziness (PPPD or visual vertigo) is a condition where certain visual environments can trigger episodes of dizziness and nausea.  We have put together a collection of videos showing different environments that might or might not trigger vertigo symptoms.

At the Balance Interest Group meeting (London, September 2016) a number of clinicians in the audience suggested these videos might be useful to ascertain from patients which environments are triggers for their symptoms.

Visual Vertigo
Example screenshots from the videos

Some of the videos are real life recordings of everyday environments, such as supermarkets, corridors and parks. These environments are shown in different ways, for example, standing still, rotating head, and moving forwards and backwards.

The other videos show movements through virtual environments (‘corridors’). Some of these are meant to be simulated versions of natural environments (such as supermarkets) others are very simplified environments that isolate certain visual features (such as orientation and spatial frequency).

Using these videos

If you are a clinician who would like to use the videos, please read the Guidance Document.
