Abstract: Disclosed is a method for determining a gaze direction of a user (5) by employing a neural network (220) operating on the basis of image data of an image of a face of the user (5). The neural network (220) detects an ellipse (20) representing an outer border of an iris (17) of the user’s eye (15) and outputs a first vector (31), a second vector (32) and a respective first and second probability (p1, p2) representing the probability that the first vector (31) or the second vector (32) is the gaze direction Further disclosed are an apparatus configured to perform such method and a vehicle comprising such apparatus.

Abstract: A monitoring system for monitoring a kinematic coupling between an actuator and an element controlled by the latter includes a first sensor to detect the operative movement of the actuator. A second sensor is designed to detect the actual movement of the controlled element. A computer unit, based on the operative movement of the actuator, determines an anticipated movement of the controlled element and compares this anticipated movement with the actual movement of the controlled element. An error message is emitted when a value of the deviation between the anticipated movement and the actual movement exceeds a predefined threshold value.

Abstract: A method for identifying occupant-specific settings for a vehicle comprises detecting a vehicle occupant; collecting biometric occupant data of the detected vehicle occupant; assembling a descriptor based on at least part of the collected occupant data; storing the descriptor in a database; and updating a cluster of descriptors in the database based on the assembled descriptor, wherein descriptors grouped in the cluster are close to each other, and wherein the cluster corresponds to the detected vehicle occupant. Based on the cluster and assembled descriptor can be assigned to the cluster, and vehicle setting data can be calculated that has been stored in association with the cluster. The vehicle setting data corresponds to occupant-specific settings for the vehicle. A vehicle comprises a system capable of performing such method.

Abstract: A method for displaying a pointer in an instrument panel is described. The method comprises retrieving a current instrument status of an instrument of the instrument panel that is to be displayed, determining a pointer form on the basis of the current instrument status, retrieving of the determined pointer form from a texture atlas, and rendering the pointer in the instrument panel with the retrieved pointer form. There is further described a device for displaying an instrument panel, which device comprises a display module configured to display at least one instrument panel having at least one pointer instrument, and a controller configured to carry out the method using the display module. A vehicle having such a device is also disclosed.

The DTI may then be used in relation to part evaluation including through simulated use of the part. The physical instance of the part may be evaluated by way of the DTI or the DTI may be used to generate maintenance schedules specific to the physical instance of the part.
