Instructions (how to do it)
This one is not strictly a MIRAGE illusion, but it came about through our MIRAGE research. This is one that anybody can do at home and gives the illusion of having an extra finger on one hand.

We had some fun with this experiment and publication. Through our many public engagement events we knew that finger stretching works on just about everyone, but we had never formally measured that and this paper was the result.

An experiment using our finger stretching (and shrinking) illusion from our Malaysian collaborators and a first publication for Treshi. Changing the perceived shape of your body changes how you process touch on the changed body part.

The first use of our tingling hand illusion which uses a visual effect to make it feel as though your hand is tingling, even though we do nothing to your real hand.

This one took the visual space that the hand moved around in and squashed it up on one side only to see if we could model what might be happening in some people following brain damage.

Here, we used finger stretching illusion technology to see if we could stretch the arm from a third-person perspective (like watching yourself from a distance).

One of our absolute favourites. The illusion makes it feel as though your hand has disappeared. You can find out more about this in the illusions section on this site.

A further development of the supernumerary (two hands) illusion. In this one we destroyed ownership of the limb by passing a wooden stick through the hand.

The press went mad for this. We used our finger stretching illusion on people with painful osteoarhtritis in the hand and showed that multi sensory illusions can change the way people experience pain.

This is actually one of my favourite experiments: as you reach towards an object to pick it up your hand gets bigger, the object gets bigger or other objects nearby move. Our brain is pretty good at dealing with all of this.

We might have done this one because we could. For this paper we stretched the finger until the tip popped off. Then we stabbed it with a stick.

The first use of virtual limb duplication and one of our most cited papers. We showed that by changing how the hand moved could change whether your brain thought it was yours or not.

The first MIRAGE publication. Quite complicated, but essentially we used virtual displacement of the limb to undo the effects of prisms (which shift everything you see to one side). It was horribly complicated, but it got us started.
