The chapter explores the development of Elastic 3D Spaces as a research group, its span of inquiry, along with developments to date, using old and new technologies, including stereoscopy and augmented and virtual reality. Elastic 3D Spaces alludes to the space in front of a screen where images appear when using stereo to create 3D, where objects pop out of the screen. The perception of depth stretches if the viewer can move, hence elastic space. The chapter explores art projects whilst positioning the subject area involving both arts and science researchers and explains the topics it covers. Elastic 3D Spaces is interested in comparisons between 3D experiences and stereo 3D experiences from projection to virtual reality.
