Abstract

A method, apparatus, and computer program product are provided to facilitate performing focus correction of displayed information. In the context of a method, a focus distance of a user is determined. The method may also determine determining at least one focal point setting for one or more dynamic focus optical components of a display based on the focus distance. The method may also cause a configuring of the one or more dynamic focus optical components based on the at least one focal point setting to present a representation of data on the display.

Claims

1. A method comprising:

determining a focus distance of a user;

determining at least one focal point setting for one or more dynamic focus optical components of a display based on the focus distance; and

causing a configuring of the one or more dynamic focus optical components based on the at least one focal point setting to present a representation of data on the display.

2. A method of claim 1, further comprising:

determining the focus distance based on gaze tracking information.

3. A method of claim 1, further comprising:

determining a depth for presenting the representation on the display;

determining another depth for viewing information through the display;

determining a focus mismatch based on the depth and the another depth; and

determining the at least one focal point setting to cause a correction of the focus mismatch.

4. A method of claim 3, wherein the display includes a first dynamic focus optical component and a second dynamic focus optical component, the method further comprising:

determining a deviation of a perceived depth of the representation, information, or a combination thereof resulting from a first one of at least one focal point setting configured on the first dynamic focus optical component;

determining a second one of the at least one focal point setting based on the deviation; and

causing a configuring of the second dynamic focus optical component based on the second one of the at least one focal point setting to cause the correction of the focus mismatch.

5. A method of claim 1, further comprising:

determining at least one vergence setting for the one or more dynamic focus optical components based on the focus distance,

wherein the at least one vergence setting includes a tilt setting for the one or more dynamic focus optical components.

6. A method of claim 1, further comprising:

determining a depth, a geometry, or a combination thereof of information viewed through the display based on depth sensing information; and

determining the focus distance, a subject of interest, or a combination thereof based on the depth, the geometry, or a combination thereof.

7. A method of claim 1, further comprising:

determining the representation based on the focus distance, the at least one focal point setting, or a combination thereof.

8. A method of claim 1, wherein the display is a see-through display;

and wherein a first one of the one or more dynamic focus optical components is positioned between a viewing location and the see-through display, and the second one of the one or more dynamic focus optical components is positioned between the see-through display and information viewed through the see-through display.

9. An apparatus comprising:

at least one processor; and

at least one memory including computer program code for one or more programs,

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to at least;

determine a focus distance of a user;

determine at least one focal point setting for one or more dynamic focus optical components of a display based on the focus distance; and

cause a configuring of the one or more dynamic focus optical components based on the at least one focal point setting to present a representation of data on the display.

10. A method of claim 9, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:

determine the focus distance based on gaze tracking information.

11. A method of claim 9, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:

determine a depth for presenting the representation on the display;

determine another depth for viewing information through the display;

determine a focus mismatch based on the depth and the another depth; and

determine the at least one focal point setting to cause a correction of the focus mismatch.

12. A method of claim 11, wherein the display includes a first dynamic focus optical component and a second dynamic focus optical component, and wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:

determine a deviation of a perceived depth of the representation, information, or a combination thereof resulting from a first one of at least one focal point setting configured on the first dynamic focus optical component;

determine a second one of the at least one focal point setting based on the deviation; and

cause a configuring of the second dynamic focus optical component based on the second one of the at least one focal point setting to cause the correction of the focus mismatch.

13. A method of claim 9, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:

determine at least one vergence setting for the one or more dynamic focus optical components based on the focus distance,

wherein the at least one vergence setting includes a tilt setting for the one or more dynamic focus optical components.

14. A method of claim 9, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:

determine a depth, a geometry, or a combination thereof of information viewed through the display based on depth sensing information; and

determine the focus distance, a subject of interest, or a combination thereof based on the depth, the geometry, or a combination thereof.

15. A method of claim 9, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:

determine the representation based on the focus distance, the at least one focal point setting, or a combination thereof.

16. A method of claim 9, wherein the display is a see-through display;

and wherein a first one of the one or more dynamic focus optical components is positioned between a viewing location and the see-through display, and the second one of the one or more dynamic focus optical components is positioned between the see-through display and information viewed through the see-through display.

17. A computer program product comprising at least one non-transitory computer-readable storage medium having computer-readable program instructions stored therein, the computer-readable program instructions comprising:

program instructions configured to determine a focus distance of a user;

program instructions configured to determine at least one focal point setting for one or more dynamic focus optical components of a display based on the focus distance; and
