Abstract: PROBLEM TO BE SOLVED: To provide a method and algorithm for analyzing eye movement data generated by a head and/or eye movement system and outputting characteristic data.SOLUTION: In the method, the eye movement data is processed using a processor by applying classification rules to the data and thereby identifying visual fixations experienced by the subject. Analysis is also made of gaze-direction information associated with the identified fixations thereby developing data representative of directions in which the subject visually fixated during the period of data collection. The data is segregated, based partially on gaze-direction of fixations, into delimited data sets, each delimited data set representing an area/object-of-subject-interest existing during the period of data collection. At least one of the delimited data sets represents a region of typical eyes-forward driving based on a high-density pattern assessed from the collected gaze-direction data. Characteristics of a driver of Percent Road Center (PRC) are calculated based on data representing relative quantification of eyes-forward driving maintained by the driver during a predetermined period.

Abstract: PROBLEM TO BE SOLVED: To provide a method for presenting comparison measures in assessing driver activity and/or driver condition. SOLUTION: This method includes collecting a stream of gaze-direction data based on a sensed characteristic of a driver, ascertaining a region representative of typical eyes-forward driving based on a high-density pattern determined from the collected gaze-direction data; and utilizing the collected gaze-direction data, in comparison to the ascertained representative region of typical eyes-forward driving, to identify and assess the severity of at least one of the following driver impairment characteristics based on the comparison: (1) cognitive driver distraction, (2) visual driver distraction, and (3) high driver work load.

Abstract: Method for assuring that the operator of a vehicle is an authorized driver, the method comprising utilizing an onboard, multi-mode driver identification system to ascertain whether an operator is an authorized driver. A first driver identification procedure is performed on a present operator of the vehicle and determining whether the present operator is an authorized or unauthorized driver of the vehicle. A second driver identification procedure is performed on the present operator of the vehicle and determining whether the present operator is an authorized or unauthorized driver of the vehicle, wherein the first and second driver identification procedures are performed with a time interval therebetween, the time interval being dependent upon the nature of the work being performed by the operator. A remedial measure is exercised to avert potentially negative impact when the present operator of the vehicle is determined to be an unauthorized driver based upon at least one of the performed identification procedures.

Abstract: A method and system for communication and/or interaction between a vehicle driver (D) and a plurality of integrated and/or non-integrated applications (2; 3) like e.g. native vehicle applications and/or aftermarket applications and/or nomad applications is disclosed. Especially, such a method and system for managing the communication and/or interaction by means of an interaction manager (41) is provided, by which this communication and/or interaction is conducted or managed in such a way that risks and impairments for the safety and comfort of the driver are reduced considerably and workload and distraction of the driver are reduced considerably as well.

Abstract: A method is proposed for verifying a vehicle operator's identity utilizing biometric data that can change over time for a particular person thereby potentially permitting a verification failure of that person based on a comparison of current biometric measures against a previously-produced template of the same characteristics, said method comprising automatically updating the previously-produced template, said automatic update being achieved in a multi-modal verification system wherein said verification system uses more than one biometric/PIN-code/smart card, wherein upon the operator entering the vehicle a prompt is issued requiring identity verification using PIN-code, fingerprint and face recognition, and after which the system verifies the operator identity using PIN-code and face recognition and uses the fingerprint biometric to update the fingerprint template in the database.
