Barry Blundell's "3D Displays and Spatial Interaction"

Exploring the Science, Art, Evolution and Use of 3D Technologies

“3D Displays and Spatial Interaction, Vol I” has now been made available for free download from Barry's website – The book can be downloaded in two parts, the first PDF file contains the Front Matter plus Chapters 1 through to 4, and the second file contains Chapters 5 through to 9, the Appendix, and an extensive reference list (comprising just over 700 references).

Here are some excerpts from the Forward, "The author needs little introduction; he is a highly-regarded historian of ‘the technology of images’, with a deep knowledge fuelled by his own groundbreaking work in volumetric 3-D display. I have learned a great deal in the pages of Barry’s writings since I entered the field of 3-D display in 1988.

This book is exciting for two reasons. First, you’ll learn - in a very clear, completely illustrated manner – about perception, interaction, and image display. For example, in perception, you’ll encounter the architecture of the eye, a deep catalogue of depth cues, and the visual cortex. You’ll learn about haptics and interaction, including the fundamental Fitts’ Law of visual and physical target acquisition. The book is rounded out (so to speak) with Barry’s excellent teachings on a complete variety of three-dimensional displays, spanning stereoscopic, lenticular, parallax barrier, and volumetric systems.

Second, I enjoy his writing because he magically expresses treasure-troves of deep historical and scientific knowledge underlying a variety of topics. Ever wonder not about who really invented the stereoscope, but what they argued over? What’s a horopter or how do you compute 3-D imagery? Never mind ‘what’s a volumetric display’, what might its embedded electronics look like?

I hope you’ll agree that a book of this sort has really been a long time coming. When I got a sneak preview, I certainly enjoyed page after page of history and science that was new to me, even after working in the display industry for 20 years.
