Abstract

An electronic system includes a portable display device and a guiding device. The portable display device includes a first display unit for displaying images of scenes according to a first field of view, a control unit for generating information of a current viewing area of one of the images to be displayed on the first display unit and a first communication unit for outputting the information of the current viewing area. The guiding device includes a second communication unit for receiving the information of the current viewing area from the portable display device and a processing unit for generating guidance information according to the information of the current viewing area. Wherein the second communication unit transmits the guidance information to the first communication unit, and accordingly the control unit performs a guidance task according to the guidance information.

First claim

What is claimed is:

1 . An electronic system, comprising:
a portable display device, comprising:
a first display unit for displaying images of scenes according to a field of view;
a control unit for generating information of a current viewing area of one of the images to be displayed on the first display unit; and
a first communication unit for outputting the information of the current viewing area; and
a guiding device, comprising:
a second communication unit for receiving the information of the current viewing area from the portable display device; and
a processing unit for generating guidance information according to the information of the current viewing area;
wherein the second communication unit transmits the guidance information to the first communication unit, and accordingly the control unit performs a guidance task according to the guidance information.

2 . The electronic system of claim 1 , wherein the guidance information comprises a command associated with the guidance task.

3 . The electronic system of claim 1 , wherein the first display unit displays an addition indication controlled by the control unit for performing the guidance task.

4 . The electronic system of claim 1 , wherein the portable display device further comprises:
an indication unit for implementing an indication function controlled by the control unit for performing the guidance task.

5 . The electronic system of claim 4 , wherein the indication unit comprises at least one of a light device, a speaker and a vibration device.

6 . The electronic system of claim 1 , wherein the portable display device further comprises:
a camera unit for capturing auxiliary images associated with the environment; wherein the first communication unit transmits the auxiliary images to the second communication unit and accordingly the processing unit generates the guidance information according to the information of the current viewing area and the auxiliary images.

7 . The electronic system of claim 1 , wherein the processing unit further adds an object on the first image, so as to generate an edited image to be displayed on a second display unit of the guiding device.

8 . The electronic system of claim 7 , wherein the object comprises at least one of an anchor icon, a point icon, a symbol and a text.

9 . The electronic system of claim 1 , wherein the guidance device further comprises:
a second display unit for displaying a first viewing area of the images of the scenes; wherein the first viewing area of the images to be displayed on the second display unit is greater than the current viewing area of the one of the images to be displayed on the first display unit.

10 . A portable display device, comprising:
a first display unit for displaying images of scenes according to a field of view; a control unit for generating information of a current viewing area of one of the images to be displayed by the first display unit; and a communication unit for transmitting the information of the current viewing area to a guiding device.

11 . The portable display device of claim 10 , wherein the communication unit receives guidance information associated with a guidance task from the guiding device, and accordingly the control unit performs the guidance task according to the guidance information.

12 . The portable display device of claim 10 , wherein the guidance information comprises a command associated with the guidance task.

13 . The portable display device of claim 10 , wherein the first display unit displays an addition indication controlled by the control unit for performing the guidance task.

14 . The portable display device of claim 10 , further comprising:
an indication unit for implementing an indication function controlled by the control unit for performing the guidance task.

15 . The portable display device of claim 14 , wherein the indication unit comprises at least one of a light device, a speaker and a vibration device.

16 . The portable display device of claim 10 , further comprising:
a camera unit for capturing auxiliary images associated with the environment; wherein the communication unit transmits the auxiliary images to the guiding device.

17 . A guiding device, comprising:
a communication unit for receiving information of a current viewing area of an image to be displayed by the portable display device; and a processing unit for generating guidance information associated with a guidance task according to the information of the current viewing area; wherein the communication unit transmits the guidance information to the portable display device for guiding the portable display device to perform the guidance task.

18 . The guiding device of claim 17 , wherein the guidance information comprises a command associated with the guidance task.

19 . The guiding device of claim 17 , wherein the communication unit receives auxiliary images associated with the environment of the portable display device from the portable display device, and accordingly the processing unit generates the guidance information according to the information of the current viewing area and the auxiliary images.

20 . The guiding device of claim 17 , wherein the processing unit further adds an object on the first image, so as to generate an edited image to be displayed on a second display unit.

21 . The guiding device of claim 20 , wherein the object comprises at least one of an anchor icon, a point icon, a symbol and a text.

22 . The guiding device of claim 17 , further comprising:
a second display unit for displaying a first viewable area of the images; wherein the first viewing area of the images to be displayed on the second display unit is greater than the current viewing area of the image to be displayed on the first display unit.
