Method for assisting a user in performing a scrolling operation, device and motor vehicle

Abstract

Method for assisting a user (12) in performing a scrolling operation to scroll scrollable content (14) on a display device (16), wherein the scrolling operation is triggered depending on a detected triggering action performed by the user (12) and is automatically continued after triggering for at least a predefinable period of time, wherein a gaze characteristic (B) of the user (12) is detected over time (t1, t2, t3, t4, t5, t6, t7, t8, t9, t10, t11, t12) by means of a gaze detection device (20), wherein, provided that the temporal progression (t1, t2, t3, t4, t5, t6, t7, t8, t9, t10, t11, t12) of the gaze characteristic (B) with respect to the scrollable content (14) fulfills a predetermined criterion, it is determined that the user (12) is interested in at least a part (14a) of the scrollable content (14) currently displayed on the display device (16) during the automatic continuation of the scrolling process, and an actual speed (v1) of the automatically continued scrolling process is reduced, wherein the predetermined criterion is then considered fulfilled if a predetermined long duration (Δt2) of a fixation of a gaze (B) of the user (12) with respect to the part (14a) of the scrollable content (14) is recorded, wherein the predetermined long duration is an absolute value of a fixation of a Blicks (B) represents or a relative value based on an average duration of fixations on unsearched parts of the scrollable content,, characterized by the fact that the speed (v1) is reduced to a non-zero speed value (v2), whereby the automatic continuation of the scrolling process is terminated upon detection of a gaze-independent termination operation performed by the user (12).
