Degree of Subject’s Indecisiveness Characterized by Eye Movement Patterns in Increasingly Difficult Tasks
Résumé
Indecisiveness is, for some people, a character trait that manifests as a difficulty in settling between several simple or complex alternatives. It is an irritating character trait from a theoretical point of view, as it can be difficult to explain or decipher; it also becomes irritating from a practical point of view, as it seems particularly resistant to modification, sometimes even increasing while one tries to reduce it. This study of indecisiveness is part of the Agence Nationale de la Recherche (ANR) project 0RIGAMI2 ("Observation du Regard et Interprétation du Geste pour une Analyse Marketing Non Intrusive," or "observation of Gaze and Interpretation of Gesture for a Nonintrusive Marketing Analysis"). ORIGAMI2 aims at a complete analysis of the customer's decision-making process through the combination of various data acquisition tools. The analysis of a decision-making process involves three steps. First, the stimuli with which the customer is interacting must be identified. Second, the customer's behavior must be interpreted based on his hesitations, time spent staring at different objects, etc. Finally, behavior patterns that take place during the decision-making process need to be identified. Our present work is related to the second and third Steps, with the goal of building a predictive model of a person's degree of indecisiveness through the use of eye-tracking methodology. First, we needed to extract relevant descriptors.
