Abstract

Graphical viewing of shapes and descriptive information in displayed graphical images. In one aspect, shape information is displayed in a graphical interface using a computer system and includes causing a display of an image and one or more shapes in the image, and causing a display of a cursor on the display device. Labels are displayed on the display device, each label associated with a different displayed shape. One or more of the labels are displayed within a zone of focus of eyes of a user of the graphical interface and one or more of the labels are displayed outside the zone of focus, where the labels displayed in the zone of focus are displayed differently than the labels displayed outside the zone of focus.

Claims

1. A method for displaying shape information in a graphical interface using a computer system, the method comprising:

causing a display of an image on a display device, wherein one or more shapes are displayed in the image;

causing a display of a cursor on the display device, a displayed position of the cursor being controlled by a user of the graphical interface using an input device;

determining one or more dimensions describing a zone of focus for a user on a display of the display device, wherein the one or more dimensions are based on allowing the user to focus on and visually process objects displayed within the zone of focus while the eyes of the user are fixedly maintained without visually processing other objects displayed outside the zone of focus; and

causing a display of a plurality of labels on the display device, each of the labels being an object associated with and providing information relating to an associated one of the displayed shapes, wherein displayed positions of the labels are based at least in part on positions of their associated shapes and are based at least in part on the one or more dimensions describing the zone of focus, and wherein the positions of the associated shapes are not based on the one or more dimensions describing the zone of focus.

2. The method of claim 1 wherein the shapes represent traces in a circuit layout.

3. The method of claim 1 wherein each of the labels is displayed only if the associated shape is above a predetermined threshold size.

4. The method of claim 1 further comprising determining a center of the zone of focus currently viewed by the user,

wherein each of the plurality of labels is displayed overlaid on its associated shape,

wherein the display of the labels includes displaying the labels that are positioned within the zone of focus at a location towards the center of the zone of focus and away from a center of the associated shapes while overlaid on the associated shapes, and

wherein the labels that are positioned outside the zone of focus are displayed overlaid on the associated shapes at a location approximately centered on the associated shapes.

5. The method of claim 4 wherein the center of the zone of focus currently viewed by the user is the location of a displayed cursor controlled by the user using an input device.

6. The method of claim 5 wherein the zone of focus is centered on the cursor only when a command using the cursor is currently active in the graphical interface and is awaiting a further input from the user based on the cursor.

7. The method of claim 1 wherein determining the one or more dimensions of the zone of focus for the user includes displaying a training image and sensing the eyes of the user viewing the training image to collect measurements used in determining the one or more dimensions of the zone of focus.

8. The method of claim 1 wherein at least one of the labels is repeatedly displayed as multiple labels for a single associated shape for at least one of the shapes, such that the single shape has multiple displayed labels.

9. The method of claim 8, wherein the single associated shape is larger than the zone of focus, and wherein the repeated labels are spaced apart by at least the one or more dimensions of the zone of focus.

20. The method of claim 1 wherein determining the one or more dimensions describing the zone of focus includes determining the one or more dimensions describing a zone of focus for a particular user, including receiving input from the particular user specifying a distance between the eyes of the particular user and the display of the display device, wherein the input is used in determining the one or more dimensions describing the zone of focus for the particular user.

21. The method of claim 1 wherein determining the one or more dimensions describing the zone of focus includes determining the one or more dimensions describing a zone of focus for a particular user, including receiving input from a camera sensing eye movement of the particular user, wherein the input is used in determining the one or more dimensions describing the zone of focus for the particular user.

10. A computer program product comprising a non-transitory computer readable medium including program instructions to be implemented by a computer and for displaying shape information in a graphical interface, the program instructions for:

causing a display of an image on a display device, wherein one or more shapes are displayed in the image;

causing a display of a cursor on the display device, a displayed position of the cursor being controlled by a user of the graphical interface using an input device;

determining one or more dimensions describing a zone of focus for a user on a display of the display device, wherein the one or more dimensions are based on allowing the user to focus on and visually process objects displayed within the zone of focus while the eyes of the user are fixedly maintained without visually processing other objects displayed outside the zone of focus; and

causing a display of a plurality of labels on the display device, each of the labels being an object associated with and providing information relating to an associated one of the displayed shapes, wherein displayed positions of the labels are based at least in part on positions of their associated shapes and are based at least in part on the one or more dimensions describing the zone of focus, and wherein the positions of the associated shapes are not based on the one or more dimensions describing the zone of focus.

11. The computer program product of claim 10 wherein the shapes represent traces in a circuit layout.

12. The computer program product of claim 10 further comprising instructions for determining a center of the zone of focus currently viewed by the user,

wherein each of the plurality of labels is displayed overlaid on its associated shape, and

wherein the display of the labels includes displaying the labels that are positioned within the zone of focus at a location towards the center of the zone of focus and away from a center of the associated shapes while overlaid on the associated shapes, and

wherein the labels that are positioned outside the zone of focus are displayed overlaid on the associated shapes at a location approximately centered on the associated shapes.

13. The computer program product of claim 12 wherein the center of the zone of focus currently viewed by the user is the location of a displayed cursor controlled by the user using an input device.

14. The computer program product of claim 13 wherein the zone of focus is centered on the cursor only when a command using the cursor is currently active in the graphical interface and is awaiting a further input from the user based on the cursor.

15. The computer program product of claim 10 wherein instructions for determining the one or more dimensions of the zone of focus for the user includes displaying a training image and sensing the eyes of the user viewing the training image to collect measurements used in determining the one or more dimensions of the zone of focus.

16. The computer program product of claim 10 wherein at least one of the labels is repeatedly displayed as multiple labels for a single shape for at least one of the shapes, such that the single shape has multiple displayed labels, and wherein the single shape is larger than the zone of focus, wherein the repeated labels are spaced apart by at least the one or more dimensions of the zone of focus.

17. A system for displaying shape information in a graphical interface using a computer system, the system comprising:

a memory; and

one or more processors in communication with the memory, the one or more processors;
