Abstract

The present invention proposes a method and apparatus for prompting based on smart glasses. The method comprises: acquiring current scenario information; determining prompt information corresponding to the current scenario information according to a preconfigured information base, the information base storing at least one kind of scenario information and prompt information corresponding to each kind of scenario information; and displaying the prompt information by means of the smart glasses. The method can facilitate the acquisition of prompt information corresponding to a scenario by a user.

Claims

1. A method for prompting based on smart glasses, comprising:

acquiring current scenario information including a page of a slide show presentation being projected via a projector and being presented via the smart glasses, an image of the page being captured by the smart glasses;

determining prompt information corresponding to the captured image of the page based upon a preconfigured information base, wherein the preconfigured information base stores a picture showing the page, prompt information including extended content for explaining the page, and an association relationship between the page and the prompt information, and wherein the extended content is not displayed via the projector;

receiving a voice control instruction enabling a part of the prompt information that includes the extended content for explaining a selected part of the captured image; and

displaying, via the smart glasses, the part of the prompt information based upon the voice control instruction.

2. The method of claim 1, further comprising establishing the information base by saving incoming scenario information and incoming prompt information corresponding to the scenario information in the information base.

3. The method of claim 1, further comprising establishing the information base by saving incoming scenario information acquired by a user from public resources and incoming prompt information corresponding to the scenario information in the information base.

4. The method of claim 1, wherein said acquiring includes capturing a current scenario to acquire an image of the current scenario.

5. The method of claim 4, wherein said capturing includes:

capturing the scenario continuously to acquire the image of the current scenario;

capturing the current scenario according to an event trigger instruction;

or a combination thereof.

6. The method of claim 5, wherein the event trigger instruction includes:

a touch instruction given by a user;

a voice control instruction given by the user;

a trigger instruction sent by the user via a user device;

or a combination thereof.

7. The method of claim 1, wherein said acquiring includes receiving the current scenario information sent by a device that is located where the current scenario is located.

8. The method of claim 1, wherein said displaying includes:

judging whether the prompt information corresponding to the current scenario information is to be displayed; and

displaying the prompt information via the smart glasses based upon said judging.

9. The method of claim 8, wherein said judging comprises:

judging that the prompt information is to be displayed based upon all prompt information being enabled;

judging that the prompt information is to be displayed based upon the prompt information

corresponding to the current scenario being enabled;

or a combination thereof.

18. The method of claim 1, further comprising establishing the information base by inputting in the information base each page of the slide show presentation and the prompt information respectively corresponding to each page.

19. The method of claim 1, further comprising establishing the information base by inputting in the information base a page number of the page of the slide show presentation and the prompt information respectively corresponding to the page number.

20. The method of claim 1, wherein said displaying comprises displaying the part of the prompt information via the smart glasses upon an arranged sensor of the smart glasses determining that an eyeball stares at the page via the smart glasses for a staring time exceeding a set threshold.

10. An apparatus for prompting based on smart glasses, comprising one or more processors associated with the smart glasses and being configured to:

acquire current scenario information including a page of a slide show presentation being projected via a projector and being presented via the smart glasses, an image of the page being captured by the smart glasses;

determine prompt information corresponding to the captured image of the page based upon a preconfigured information base, wherein the preconfigured information base stores a picture showing the page, prompt information including extended content for explaining the page, and an association relationship between the page and the prompt information, and wherein the extended content not being displayed via the projector;

receiving a voice control instruction enabling a part of the prompt information that includes the extended content for explaining a selected part of the captured image; and

display, via the smart glasses, the part of the prompt information based upon the voice control instruction.

11. The apparatus of claim 10, wherein said one or more processors are configured to establish the information base by saving incoming scenario information and incoming prompt information corresponding to the scenario information in the information base.

12. The apparatus of claim 10, wherein said one or more processors are configured to establish the information base by saving incoming scenario information acquired by a user from public resources and incoming prompt information corresponding to the scenario information in the information base.

13. The apparatus of claim 10, wherein said one or more processors are configured to capture a current scenario to acquire an image of the current scenario.

14. The apparatus of claim 13, wherein said one or more processors are configured to:

capture the scenario continuously to acquire the image of the current scenario;

or

capture the current scenario according to an event trigger instruction.

15. The apparatus of claim 14, wherein the event trigger instruction includes:

a touch instruction given by a user;

a voice control instruction given by the user;

or

a trigger instruction sent by the user via a user device.

16. The apparatus of claim 10, wherein said one or more processors are configured to receive the current scenario information sent by a device that is located where the current scenario is located.

17. A non-transitory computer storage medium including at least one program for prompting based on smart glasses when implemented by a processor, comprising:

instruction for acquiring current scenario information including a page of a slide show presentation being projected via a projector and being presented via the smart glasses, an image of the page being captured by the smart glasses;

instruction for determining prompt information corresponding to the page number based upon a preconfigured information base, wherein the preconfigured information base stores a picture showing the page, prompt information including extended content for explaining the page, and an association relationship between the page and the prompt information, and wherein the extended content not being displayed via the projector;

receiving a voice control instruction enabling a part of the prompt information that includes the extended content for explaining a selected part of the captured image; and

instruction for displaying, via the smart glasses, the part of the prompt information based upon the voice control instruction.
