(EN) METHOD AND APPARATUS FOR DETERMINING AND ANALYZING A LOCATION OF VISUAL INTEREST

Abstract
(EN)
A method on analyzing data based on the physiological orientation of a driver is provided. Data is descriptive of a driver's gaze-direction is processing and criteria defining a location of driver interest is determined. Based on the determined criteria, gaze-direction instances are classified as either on-location or off-location. The classified instances can then be used for further analysis, generally relating to times of elevated driver workload and not driver drowsiness. The classified instances are transformed into one of two binary values (e.g., 1 and 0) representative of whether the respective classified instance is on or off location. The uses of a binary value makes processing and analysis of the data faster and more efficient. Furthermore, classification of at least some of the off-location gaze direction instances can be inferred from the failure to meet the determined criteria for being classified as an on-location driver gaze direction instance.

L'invention concerne un procédé d'analyse de données reposant sur l'orientation physiologique d'un conducteur. Les données sont descriptives de la direction du regard du conducteur et l'on détermine des critères définissant un emplacement d'intérêt du conducteur. Sur la base des critères déterminés, les cas de figure de direction du regard sont classés en ceux de regard dirigé vers l'emplacement et de regard non dirigé vers l'emplacement. Les cas de figure classés peuvent alors servir à la poursuite de l'analyse, généralement relative aux moments de charge de travail plus importante pour le conducteur et non à la somnolence du conducteur. Les cas de figure classés sont transformés en l'une de deux valeurs binaires (par exemple, 1 et 0) indiquant si le cas de figure respectif classé est un cas de regard dirigé vers l'emplacement ou non. L'utilisation d'une valeur binaire rend le traitement et l'analyse des données plus rapide et plus efficace. De plus, le classement d'au moins certains des cas de figure de regard non dirigé vers l'emplacement peut découler de l'échec à répondre aux critères déterminés de classement comme cas de figure de regard du conducteur dirigé vers l'emplacement.
