Projection poi is a theatrical branch of kinetic art combining projection and live interaction to create an optical illusion, incorporating prop manipulation inspired by poi, martial arts weaponry and dance. This unique technique allows the audience to see projected light without a screen or surface (although a screen or surface can be used) instead relying on high speed movement and prop interaction with the projector beam to make the light visible. This technique enables images, words, film or animation to appear as if floating in the air.

Props
To maximise and create the effect thin, flexible, white props are used, although variations on size and colour offer a different effect. White props allow the greatest reflection of projected light, and when the prop repeatedly intercepts the light beam at high speed the flexibility and thinness of the prop give the illusion that a whole image can be seen (if the prop were to stop you'd only see a section of the image). Ropes, bungee chords, staffs, pvc conduit and the edges of handheld fans have been used publicly, although a number of props have been used in theatre laboratory. Ideally the flexibility will become more apparent when the prop is manipulated for example: the curve of a rope when it is spun.
Backgrounds
Visible
Being able to see the projected light on a surface with the live performer interacting with the beam in-between the surface and the projector. The performer brings forward and highlights specific areas of the projection as the audience can see what is on the surface behind the performer and an image where the performer is interacting.
Non-visible
Distorting, obscuring or destroying the projected light by using a surface that is not flat or specifically designed to do so, or by overpowering the light with an alternative source such as theatre lights. This allows for choreography to reveal the image with the greatest, most appropriate dramatic effect, as the image is only visible when interacted with.
The two background types can be combined.
History
Projection poi was developed and first performed by Kylie Ann Smith and Ricky White of Welsh theatre group gaijin-san company, at Chapter Arts Centre in April 2007 who have since developed and performed the effect in venues across Wales with commissions from Welsh Independent Dance for 'Animangamon' and the Arts Council of Wales for 'Mr. Foreigner'. During the first International Festival of Emerging Artists hosted by the Theatre Royal Stratford East in 2008 Projection Poi was investigated in theatre laboratory by artists from across the globe. The effect was first described in theatre critic Michael Kelligan's review of gaijin-san company's production 'Ma Lau' as "colourful stick bending" in April 2007.
