In the complex interplay of different visual cues\, binocular vision had pr oved especially elusive\, and the tangible sense of solidity and spatial de pth with which it is associated became a recognised component of visual exp erience\, only after experiments by Charles Wheatstone in the 1830s demonst rated our capacity to derive sensation from the differing perspectives offe red by each eye. By the end of the nineteenth-century\, through the popular philosophical lectures of\, amongst others\, Hermann von Helmholtz and Hen ri Poincaré\, the new found understanding of vision revealed by studies in physiology and optics would eventually find its way into the thinking of a new generation of artists and architects. Poincaré proved especially infl uential and his observations on geometry\, vision and space became an inspi ration for a number of early twentieth-century artists\, intent on creating a new form of spatial expression in art and architecture. My thesis as a whole will deal more broadly with the science of physiological optics and i ts relation to avant-garde spatial devices. In this presentation\, however\ , I will focus on a particular passage drawn from La Science et l’hypothà ¨se\, through which\, Poincaré sought to reveal a disparity between the co nventional understanding of space\, and the sensory cues upon which spatial experience is based. \n SUMMARY:PhD Research Conversations seminar: On Visual Depth and Pictorial S pace DTSTART:20071030T170000 CREATED:20071025T112415 DTSTAMP:20080907T182820 LOCATION:University College London Main Building\, N & S Junctions Gustave Tuck Lecture Theatre END:VEVENT END:VCALENDAR
