Cette étude propose un modèle mathématique d'un système d'interface de pointage basé sur les gestes pour simuler des comportements de pointage dans diverses situations. Nous supposons une interaction entre une interface de pointage et un utilisateur en tant que système humain dans la boucle et la décrivons en utilisant la théorie du contrôle par rétroaction. Le modèle est formulé comme un hybride d'un composant de suivi de la valeur cible et d'un composant de compensation des perturbations. Ceux-ci sont induits à partir de la même boucle de rétroaction mais avec des ensembles de paramètres différents pour bien décrire les caractéristiques de pointage humain. Les deux ensembles de paramètres optimaux ont été déterminés individuellement pour représenter avec précision les comportements de pointage réels pour les signaux d'entrée pas à pas et les séquences de perturbations de marche aléatoires, respectivement. Le modèle calibré est utilisé pour simuler des comportements de pointage pour des signaux d'entrée arbitraires attendus dans des situations pratiques. Grâce à des évaluations expérimentales, nous avons analysé quantitativement les performances du modèle hybride proposé en ce qui concerne la précision avec laquelle il peut simuler les comportements de pointage réels et avons également discuté de l'avantage du modèle de base non hybride. Des améliorations du modèle pour une plus grande précision sont également suggérées sur la base des résultats de l’évaluation.

Abstract: This study proposes a mathematical model of a gesture-based pointing interface system for simulating pointing behaviors in various situations. We assume an interaction between a pointing interface and a user as a human-in-the-loop system and describe it using feedback control theory. The model is formulated as a hybrid of a target value follow-up component and a disturbance compensation one. These are induced from the same feedback loop but with different parameter sets to describe human pointing characteristics well. The two optimal parameter sets were determined individually to represent actual pointing behaviors accurately for step input signals and random walk disturbance sequences, respectively. The calibrated model is used to simulate pointing behaviors for arbitrary input signals expected in practical situations. Through experimental evaluations, we quantitatively analyzed the performance of the proposed hybrid model regarding how accurately it can simulate actual pointing behaviors and also discuss the advantage regarding the basic non-hybrid model. Model refinements for further accuracy are also suggested based on the evaluation results.
