Abstract

The present disclosure is directed to systems and methods for reducing or preventing motion sickness using an animated overlay displayed over a content item and reflecting a detected acceleration. In some embodiments the systems and methods generate for display, on a device, a content item. The systems and methods determine an acceleration of the device along a vector, where the vector comprises a vector component that is normal to a plane defined by the display of the content item. The systems and methods then generate for display a graphical overlay over the display of the content item, wherein the graphical overlay is animated to appear to move in a direction defined by the vector comprising the vector component that is normal to the plane defined by the display.

First claim

The invention claimed is:

1 . A method comprising:
generating for display, on a device comprising a display, a content item; determining an acceleration of the device along a vector, the vector comprising a vector component that is normal to a plane defined by the display; and generating for display a graphical overlay over the display of the content item, wherein the graphical overlay comprises a predefined geometric pattern that is animated to visually signal a direction defined by the vector comprising the vector component that is normal to the plane defined by the display.

2 . The method of claim 1 , wherein the graphical overlay comprises appearance of movement of at least one animated element in the direction defined by the vector comprising the vector component that is normal to the plane defined by the display.

3 . The method of claim 1 wherein the geometric pattern is animated using a two-dimensional animation comprising an effect that simulates movement along an axis that comprises the vector component normal to the plane defined by the display and a second vector component that is parallel to the plane defined by the display.

4 . The method of claim 1 wherein the geometric pattern comprises a plurality of figures arranged in a grid pattern and wherein a size of and a first distance between figures of the plurality of figures change to alter an impression of a second distance of at least a portion of the figures of the plurality of figures from the plane defined by the display.

5 . The method of claim 1 wherein the geometric pattern is animated using an animation that comprises a vanishing point, wherein a location of the vanishing point is determined based on the determined acceleration.

6 . The method of claim 5 wherein the location of the vanishing point changes dynamically based on the determined acceleration.

7 . The method of claim 1 wherein the geometric pattern comprises a plurality of concentric circles, wherein animation of the geometric pattern comprises movement of each circle of the plurality of concentric circles synchronized with movement of an innermost circle of the plurality of concentric circles, and wherein the innermost circle moves according to the vector comprising the vector component that is normal to the plane defined by the display.

8 . The method of claim 7 wherein each circle of the plurality of concentric circles is in the foreground compared to a last circle of the plurality of concentric circles each circle of the plurality of concentric circles encapsulates.

9 . The method of claim 1 wherein the geometric pattern is animated in a color contrasting a dominant color on the display of the device.

10 . The method of claim 1 further comprising:
tracking a position of a head of a user; and
modifying the graphical overlay to align with the tracked position of the head of the user.

11 . The method of claim 1 further comprising:
tracking an eye gaze of a user; and
modifying the graphical overlay to align with the tracked eye gaze of the user.

12 . The method of claim 1 wherein generating for display the graphical overlay is by an XR device and wherein the XR device is different than the device generating for display the content item.

13 . A method comprising:
generating for display, on a device comprising a display, a content item; determining an acceleration of the device in three dimensions; and generating for display a graphical overlay over the display of the content item, wherein the graphical overlay comprises a predefined geometric pattern that is animated to visually signal animation in three dimensions defined by the determined acceleration of the device in three dimensions.

14 . The method of claim 13 , wherein the graphical overlay comprises appearance of movement of at least one animated element in the three dimensions defined by the determined acceleration of the device in three dimensions.

15 . The method of claim 13 , wherein the graphical overlay comprises appearance of movement of at least one animated element in a direction that is normal to a plane defined by the display.

16 . A system comprising:
processing circuitry configured to:
generate for display, on a device comprising a display, a content item;
determine an acceleration of the device along a vector, the vector comprising a vector component that is normal to a plane defined by the display; and
generate for display a graphical overlay over the display of the content item, wherein the graphical overlay comprises a predefined geometric pattern that is animated to visually signal a direction defined by the vector comprising the vector component that is normal to the plane defined by the display.

17 . The system of claim 16 , wherein the graphical overlay comprises appearance of movement of at least one animated element in the direction defined by the vector comprising the vector component that is normal to the plane defined by the display.

18 . The system of claim 16 wherein the geometric pattern is animated using a two-dimensional animation comprising an effect that simulates movement along an axis that comprises the vector component normal to the plane defined by the display and a second vector component that is parallel to the plane defined by the display.

19 . The system of claim 16 wherein the geometric pattern is animated using an animation that comprises a vanishing point, wherein a location of the vanishing point is determined based on the determined acceleration.

20 . The system of claim 16 wherein generating for display the graphical overlay is by an XR device and wherein the XR device is different than the device generating for display the content item.
