The Cyclopter

Phantascope: `A contrivance for exhibiting phenomena of binocular vision' O.E.D.

The Phantascopes are designed for research into the eye-brain system, either on an individual level, as part of an inter-active science context, or integrated into an educational program. As a result of the significant changes to space perception they make possible, there are many activities which may be enhanced by their use - these are a few suggestions. We would be very interested to hear of your experiences for additions to this list.

Gallery/Exhibition use – Viewing Renaissance Paintings

In 1907 Carl Zeiss patented a prismatic device which he called a Synopter. It placed both optical axes on one single axis, and he sold it to Art Galleries and Museum so that the visiting public could view the work of Renaissance painters in a virtual three dimensional space. Systems of perspective became more and more sophisticated, and all respond well to this type of viewing. The human visual system uses binocular disparity and vergence as cues to distance – being denied them by the viewing device, allows the spectator to pass more easily ‘through’ the picture plane into the virtual space of the painting, and appreciate the `space' constructed by the artist. The mirror/beamsplitter Cyclopter has a wider field of view than Zeiss's early prismatic device.

Painters – study of Life and Still-Life subjects

Painters of representational subjects such as , Still-Life, Life and Portraiture will find the Cyclopter of interest because it removes binocular disparities and vergence effects. It allows the artist to view the three-dimensional subject as a two dimensional image.

Schools of Psychology –study of effects of Monoscopic Vision

The Cyclopter is a portable hand-held device that removes all stereoscopic stimuli. There are no ‘vergence’ effects, and users experience an unusual feedback from their physical movement. Those familiar with the ‘Pulfrich’ and other spatiotemporal effects, will be interested in the effects of the performance of the Cyclopter on television images and moving targets.
