Analyse de l'activité de glaciéristes dans une perspective de conception de matériel de progression pour l'escalade et la montagne : contribution à l'élaboration d'un programme de recherche technologique en ergonomie du sport

摘要

The aim of the present thesis is twofold: first, it gives an overview onice climbers’ activity, based on an enactive empirical research program of cognitive anthropology, while developing a technological research program toevaluate appropriation situations and perspectives for design. The first part of this work focuses on the link between innovation and practice while identifying the relationship between the climbers and the technical object in order to build a technological research program focusing on the appropriation of objects. The second part is an epistemic work inculding two steps: a) to produce knowledge on the mediation role of ice axes for novice climbers and b) to develop design objects for the improvement of the research program. To this end, the usability of artifacts is highlighted (study 1) as well as the appropriability of artifacts (study 2) and then c) the theoretical object course of information is implemented using data from the activity subject and non-subject to pre-reflective consciousness to document the appropriation (study 3). The third section, however, seeks to bring about change and focuses to define the relevant criteria for the research program development and to improve the design.
