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)
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 purpose of this study was to test the usefulness of combining two types of analysis to investigate sports performance with the aim of optimizing it. These two types of analysis correspond to two levels of athletes' activity: (a) their experiences during performance and (b) the biomechanical characteristics of their movements. Rowing served as an(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)
