Distraction by use of kaleidoscope
DeviceÀ kaleidoscope is an optical device consisting of mirrors that reflect images of bits of coloured glass in a symmetrical geometric design through a viewer.
A kaleidoscope was selected as the non-electronic method of distraction, because of its wide availability due to low costs, its evolving and colourful visual stimuli, the fact that is blocks out any visualisations from the environment when used properly, and because it requires active participation (i.e., greater attention) from the subject.
