This study investigated the functional intra-individual movement variability of ice climbers differing in skill level to understand how icefall properties were used by participants as affordances to adapt inter-limb coordination patterns during performance. Seven expert climbers and seven beginners were observed as they climbed a 30 m icefall. Movement and… (More)
The aim of this study was to analyzing and modeling domestic activities (i.e. what people do in the home). The ultimate goal is to help to design ubiquitous technologies which are context sensitive and which really fit with our needs.
This short paper considers how classical concepts and approaches of cognitive ergonomics/engineering (e.g., automation, trust or control levels) could both enhance Home Energy Management Systems (HEMS) design and energy efficiency, while requiring a specific reference to home and daily life practices. We rely on initial results of a research, evaluating… (More)
The aim of this study was to examine swimmers' activity-technical device coupling during an experimental protocol (MAD-system). The study was conducted within a course-of-action theoretical and methodological framework. Two types of data were collected: (a) video recordings and (b) verbalizations during post-protocol interviews. The data were processed in… (More)
