Non-Visual Geographies

Jacobson, R.D. (2010) Non-Visual Geographies In: Warf, B. (ed.) Encyclopedia of Geography, Sage: London.


The construction, interpretation, and meaning of non-visual landscapes explores the role of sensory and perceptual modes other than vision in the construction of geographic space. It positions itself at the boundary between social theory and behavioral geography by examining the ways in which non-visual modes of information acquisition and processing reflect geographic environments and in turn shape those same places by structuring the subjective understanding and behavior of people and their symbolic understanding of space.  This understanding and representation of geographic space, occurs from several diverse conceptual perspectives, including behavioral geography and post-structuralism. At the individual level we gather
information in an environment, from all our senses other than vision: including hearing, smell, taste, and touch including kinesthesia (muscle memory). Our spatial behaviour is informed by these other sense modalities facilitating an understanding of space and place.

Multimodal virtual reality for presenting geographic information

Jacobson, R.D., Kitchin, R.M., and Golledge R.G. (2002) Multimodal virtual reality for presenting geographic information.  In: Fisher, P. and Unwin, D. (eds.) Virtual Reality in Geography. Taylor and Francis: London, pp. 382-400.


Since the conception of virtual reality (VR) environments, interaction has been predominantly visual and haptic in nature.  Only recently have developers and scientists explored non-visual and multimodal VR environments.  In this paper we examine these recent developments and assess their viability as geographic tools for people with severe visual impairments.  Our own research and  the work of others suggests that multimodal VR, where visual interaction is either augmented by, or substituted for, other forms of data such as sound and touch, offers people with severe visual impairments access to geographic information that is in many cases otherwise inaccessible.  Such offerings open up opportunities to explore the spatial relations of geographic representations and real world environments, and could qualitatively improve their quality of life.
