Gaze-based automatic scrolling
First Claim
1. A method for scrolling content that is displayed on an electronic display screen, the method comprising:
- tracking a direction of a gaze of a viewer of the displayed content; and
scrolling the displayed content on the display screen, upon detection of the tracked gaze direction on a predefined region of the display screen,wherein continuous scrolling is maintained while the tracked gaze direction is at the same region of the display screen during scrolling, and wherein the scrolling corresponds to the tracked gaze direction so as to allow smooth pursuit of the eyes of the viewer, and wherein tracking the direction of the gaze comprises calculating a displacement vector from an initial position to the gaze point, and wherein scrolling the displayed content comprises scrolling the content in a direction that is determined by a direction of the displacement vector.

Abstract
Embodiments of the invention may include a method of scrolling content on an electronic display upon detection that a gaze of a user is pointed to a pre-defined area of the display, such as for example an edge of the display. A scroll may be triggered by the gaze point of the user being directed to the pre-defined area of the screen or on a plane of the screen. A scroll may move the displayed content by a fixed amount or by a distance that is sufficient to bring the gaze point of the user our of the pre-defined area that triggered the scroll. A scroll may continue for example so long as a smooth pursuit of the viewers eyes is maintained. Embodiments may include tracking a position of a viewer of an electronic display, and altering an orientation of a one or more elements of the display to correspond to the changed orientation of the user. A layout of content that is display may be altered to accommodate the change in orientation. In some embodiments, an orientation of the displayed content may changed in real time to match the change in orientation of the user. In some embodiments, a resting or permanent orientation may be adopted once the position of the user becomes fixed.

17. An electronic device, comprising:
-
a display screen, configurable to display scrollable content; an imager, located at a known position relative to the display screen and configurable to acquire a series of images of a viewer of the display screen; and a processor, configured to; track a point of a gaze of the viewer from the series of acquired images; determine when the tracked gaze point is at a predefined area; and scroll the displayed content on the display screen, upon detection of the tracked gaze point on the predefined area, wherein the processor is configured to continuously scroll the displayed content while the tracked gaze point is at the same area during scrolling, and wherein the processor is configured to scroll in accordance with the tracked gaze point so as to allow smooth pursuit of the eyes of the viewer, and wherein the processor is configured to calculate a displacement vector from an initial position to the gaze point, and wherein the processor is configured to scroll the content in a direction that is determined by a direction of the displacement vector. - View Dependent Claims (18)
