Abstract

A display managing method for managing the display of an image to a user of an optical system comprising at least a see-through displaying device arranged and configured to display the image towards an eye of the user and an optical lens designed to be placed in front of the eye of the user and having an optical function. The method includes: an optical function data providing step, during which optical function data relating to the optical function of the optical lens are provided; and a display parameter determining step, during which a value of at least one display parameter is determined based at least on the optical function data.

First claim

The invention claimed is:

1. A display managing method for managing the display of an image to a user of an optical system comprising at least a see-through displaying device arranged and configured to display the image towards an eye of the user and an optical lens designed to be placed in front of the eye of the user and having an optical function, the method comprises:
an optical function data providing step including providing optical function data relating to the optical function of the optical lens;
a zone of interest identification step including identifying at least one zone of interest of the optical lens based on the optical function data relating to the optical function of the optical lens;
a display parameter determining step including determining a value of at least one display parameter based at least on the optical function data and on at least one zone of interest; and
wherein the image to be displayed towards the eye of the user comprises a plurality of sub-images and wherein during the display parameter determining step, a value of at least one display parameter for each sub-image of the plurality of sub-images is determined based on the at least one zone of interest.

2. The display managing method according to claim 1 , wherein the optical function data comprise at least dioptric function data relating to a dioptric function based at least on an ophthalmic correction adapted to the user.

3. The display managing method according to claim 2 , wherein the dioptric function data relate to a progressive multifocal optical design.

4. The display managing method according to claim 1 , wherein the at least one display parameter comprises the position of the image and/or angular extent of the image and/or the projection distance of the image.

5. The display managing method according to claim 1 , wherein the see-through displaying device comprises at least a tracking component adapted to determine the gazing direction of at least the eye of the user towards which the image is displayed and wherein the method further comprises a gazing direction determining step including determining the gazing direction of the eye of the user, and during the display parameter determining step, further determining the value of at least one display parameter according to the determined gazing direction.

6. The display managing method according to claim 5 , wherein the gazing direction is determined over the time and at least one distortion and/or aberration zone is identified and the value of at least one display parameter is updated based on the evolution over time of the gazing direction so as to display the image in the gazing direction avoiding the at least one distortion and/or aberration zone.

7. The display managing method according to claim 5 , further comprises an activity data providing step including providing activity data indicative of an activity of the user and further determining the value of at least one display parameter based on the activity data during the display parameter determining step.

8. A display managing component for managing the display of an image to a user of an optical system comprising at least a see-through displaying device arranged and configured to display the image towards an eye of the user and an optical lens designed to be placed in front of the eye of the user and having an optical function, the display managing component comprising:
a memory configured to store computer executable instructions, and
a processor for executing the computer executable instructions stored in the memory, wherein the computer executable instructions comprises instructions for:
providing optical function data relating to the optical function of the optical lens, identifying at least one zone of interest of the optical lens based on the optical function data relating to the optical function of the optical lens,
determining a value of at least one display parameter based on at least on the optical function data and on at least one zone of interest; and
wherein the image to be displayed towards the eye of the user comprises a plurality of sub-images and wherein during the display parameter determining step, a value of at least one display parameter for each sub-image of the plurality of sub-images is determined based on the at least one zone of interest.

9. A display managing component according to claim 8 , wherein the computer executable instructions comprises one of the following instructions for:
determining the gazing direction of the eye of the user, and wherein the value of at least one display parameter is further determined according to the determined gazing direction, and/or
providing an activity data indicative of an activity of the user, and wherein the value of at least one display parameter is further determined based on the activity data during the display parameter determining step.

10. An optical see-through displaying device comprising:
a display device configured to display an image to a user, and
a display managing component configured to manage the display of the image according to claim 8 .

11. A head mounted optical see-through displaying device configured to be worn by a user, comprising:
a see-through displaying device arranged and configured to display the image towards an eye of the user,
an optical lens designed to be placed in front of the eye of the user and having an optical function, and
a display managing component configured to manage the display of the image according to claim 8 .
