Non-Visual Geographies

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

Abstract

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.  



The assessment of non visual maritime cognitive maps of a blind sailor: a case study

Abstract

Nowadays, thanks to the accessibility of GPS, sighted people widely use electronic charts to navigate through different kinds of environments. In the maritime domain, it has considerably improved the precision of course control. In this domain, blind sailors can not make a compass bearing, however they are able to interact with multimodal electronic charts. Indeed, we conceived SeaTouch, a haptic (tactile-kinesthetic) and auditory virtual environment that allows users to perform virtual maritime navigation without vision. In this study we attempt to assess if heading or northing “haptic” views during virtual navigation training influences non-visual spatial knowledge. After simulating a navigation session in each condition, a blind sailor truly navigated on the sea and estimated seamark bearings. We used the triangulation technique to compare the efficiency of northing and heading virtual training. The results are congruent with current knowledge about spatial frames of reference and suggest that getting lost in heading mode forces the blind sailor to coordinate his current “view” with a more global and stable representation.
