De nombreuses mesures de qualité ont été proposées pour la perception de la conformité afin d'évaluer les performances des dispositifs haptiques et les résultats perçus. La conformité perçue peut être influencée par des facteurs tels que les propriétés des objets, les conditions expérimentales et les habitudes de perception humaine. Dans cet article, une analyse de la perception de la douceur a été réalisée pour découvrir les métriques de qualité pertinentes dominantes dans le système de perception de la conformité et leur corrélation avec les résultats de perception, en exprimant ces métriques par des paramètres physiques de base qui caractérisent ces facteurs. Sur la base de trois expériences psychophysiques, les différences juste perceptibles (JND) pour la douceur perçue de la combinaison de différents coefficients de rigidité et niveaux d'amortissement rendus par les dispositifs haptiques ont été analysées. Les données d'interaction au cours du processus d'interaction ont été enregistrées et analysées. Les résultats expérimentaux préliminaires montrent que la capacité de discrimination de la perception de la douceur change avec le rapport entre l'amortissement et la rigidité lorsque les sujets explorent à leur vitesse habituelle. Les résultats de l'analyse indiquent que les mesures de qualité de dureté-dureté, de dureté-dureté étendue et du rapport amortissement/rigidité ont une forte corrélation avec les résultats perçus. Les résultats d'une analyse plus approfondie montrent que les paramètres reflétant les propriétés de l'objet (rigidité, amortissement), les conditions expérimentales (bande passante de force) et les habitudes de perception humaine (vitesse initiale, taux de changement de force maximal) conduisent à la modification de ces mesures de qualité, qui apportent alors un sentiment de perception différent. et finalement entraîner un changement de capacité de discrimination. Les résultats de cet article peuvent fournir une meilleure compréhension de la perception de la douceur et des conseils utiles pour l'amélioration des dispositifs haptiques et de téléopération.

Abstract: Many quality metrics have been proposed for the compliance perception to assess haptic device performance and perceived results. Perceived compliance may be influenced by factors such as object properties, experimental conditions and human perceptual habits. In this paper, analysis of softness perception was conducted to find out relevant quality metrics dominating in the compliance perception system and their correlation with perception results, by expressing these metrics by basic physical parameters that characterizing these factors. Based on three psychophysical experiments, just noticeable differences (JNDs) for perceived softness of combination of different stiffness coefficients and damping levels rendered by haptic devices were analyzed. Interaction data during the interaction process were recorded and analyzed. Preliminary experimental results show that the discrimination ability of softness perception changes with the ratio of damping to stiffness when subjects exploring at their habitual speed. Analysis results indicate that quality metrics of Rate-hardness, Extended Rate-hardness and ratio of damping to stiffness have high correlation for perceived results. Further analysis results show that parameters that reflecting object properties (stiffness, damping), experimental conditions (force bandwidth) and human perceptual habits (initial speed, maximum force change rate) lead to the change of these quality metrics, which then bring different perceptual feeling and finally result in the change of discrimination ability. Findings in this paper may provide a better understanding of softness perception and useful guidance in improvement of haptic and teleoperation devices.
