Geometrical Touch: Drawing an Occasioned Map on the Hand

Résumé En

In this paper, based on video recordings of Orientation and Mobility (O&M) lessons for visually-disabled students, I will examine how occasioned maps (Psathas, 1979; Garfinkel, 2002), drawn in the student’s palm are interactionally traced, felt, and noticed in order to represent the shape of a crossing for all practical purposes. Touching will be examined from the perspective of the live production of "trails" on a specific region of the body, the palm of the hand. We will begin to question how such hand-drawing map episodes occur during O&M courses, stressing how the coparticipants establish a participation framework that facilitates the making of the drawing, hand-map drawings are based on lines that are neither evanescent nor permanent. Their “persistence” is not an intrinsic feature but a systematic multimodal accomplishment. We will show how the drawn lines become depictions of the streets and contribute to producing two contrasting geometrical representations of the layout of a junction.
