Abstract

A glass-type mobile terminal including a display configured to display a virtual reality image thereon; and a controller configured to detect an object around the glass-type mobile terminal while the virtual reality image is displayed on the display, and modify the virtual reality image if the detected object is a dangerous element so a viewer viewing the virtual reality image avoids the dangerous element.

First claim

What is claimed is:

1. A glass-type mobile terminal comprising:
a camera;
a display configured to display a virtual reality image thereon; and
a controller configured to:
detect an object around the glass-type mobile terminal while the virtual reality image is displayed on the display,
compare a size of a user's real activity area captured by the camera with a size of a user input area representing a minimum area required to allow a user input device to function,
increase a response sensitivity of the user input device when the size of the user's real activity area is larger than the size of the user input area, and
decrease the response sensitivity of the user input device when the size of the user's real activity area is smaller than the size of the user input area.

2. The terminal of claim 1 , wherein the controller is further configured to insert a virtual object image corresponding to the detected object into the virtual reality image.

3. The terminal of claim 2 , wherein the controller is further configured to display the virtual object image corresponding to a non-dangerous element to be different from the virtual object image corresponding to a dangerous element in the virtual reality image.

4. The terminal of claim 3 , wherein the virtual object image comprises a transparent waved-contour image corresponding to the non-dangerous element.

5. The terminal of claim 2 , wherein if the detected object is a real wall, the controller is further configured to modify the virtual reality image by inserting a virtual wall image corresponding to the real wall into the virtual reality image.

6. The terminal of claim 1 , wherein the controller is further configured to modify the virtual reality image by changing an orientation of the virtual reality image.

7. The terminal of claim 1 , wherein the controller is further configured to modify the virtual reality image by displacing a portion of the virtual reality image corresponding to a position of the detected object within the virtual reality image.

8. The terminal of claim 1 , wherein the controller is further configured to automatically adjust the response sensitivity of the user input device based on a body size of the user, wherein the user is wearing the glass-type mobile terminal.

9. The terminal of claim 1 , further comprising:
a distance sensor configured to measure a distance between the glass-type mobile terminal and the detected object,
wherein the controller is further configured to determine whether or not the detected object is a dangerous element based on the measured distance.

10. A method of controlling a glass-type mobile terminal, the method comprising:
displaying, via a display of the glass-type mobile terminal, a virtual reality image thereon;
detecting, via a controller of the glass-type mobile terminal, an object around the glass-type mobile terminal while the virtual reality image is displayed on the display;
comparing a size of a user's real activity area captured by the camera with a size of a user input area representing a minimum area required to allow the user input device to function;
increasing the response sensitivity of the user input device when the size of the user's real activity area is larger than the size of the user input area; and
decreasing the response sensitivity of the user input device when the size of the user's real activity area is smaller than the size of the user input area.

11. The method of claim 10 , further comprising:
inserting a virtual object image corresponding to the detected object into the virtual reality image.

12. The method of claim 11 , further comprising:
displaying the virtual object image corresponding to a non-dangerous element to be different from the virtual object image corresponding to the dangerous element in the virtual reality image.

13. The method of claim 12 , wherein the virtual object image comprises a transparent waved-contour image corresponding to the non-dangerous element.

14. The method of claim 11 , wherein if the detected object is a real wall, the method further comprises modifying the virtual reality image by inserting a virtual wall image corresponding to the real wall into the virtual reality image.

15. The method of claim 10 , further comprising:
modifying the virtual reality image by changing an orientation of the virtual reality image.

16. The method of claim 10 , further comprising:
modifying the virtual reality image by displacing a portion of the virtual reality image corresponding to a position of the detected object within the virtual reality image.

17. The method of claim 10 , further comprising:
automatically adjusting the response sensitivity of the user input device based on a body size of the user, wherein the user is wearing the glass-type mobile terminal.

18. The method of claim 10 , further comprising:
measuring, via a distance sensor of the glass-type mobile terminal, a distance between the glass-type mobile terminal and the detected object; and
determining, via the controller, whether or not the detected object is the dangerous element based on the measured distance.
