Abstract

A user interface provides, in a fixed screen display, for both decoupling head and body turning and for integrating them without the need for specialized equipment. Using successive synchronized viewport and contained display image movement steps, the present invention first cues the user that their body is facing in the same direction as their head. Then, by simulating the head-turn/body-turn process that humans follow when looking around for something, the invention cues the user to understand that when they look around, they are turning first their head and then their body.

Claims

1. A navigation method for a user of a computer system comprising a processor, a display, an input device and an interface, said interface comprising a view port having a starting position and containing a display image, said navigation method comprising the following steps:

a) if said user indicates a desire to navigate in a specified direction within said interface by utilizing said input device, then

i) said view port sliding in said specified direction and at a predetermined view port movement rate, and

ii) said display image shifting within said view port in a direction opposite to said specified direction and at a display image movement rate synchronized with said predetermined view port movement rate;

b) if said view port reaches a view port movement limit, then

i) said view port no longer sliding, and

ii) said display image continuing to shift within said view port in a direction opposite to said specified direction; and

,

c) if said user indicates a desire to no longer navigate in said specified direction within said interface by utilizing said input device, then

i) said view port returning to said starting position, and

ii) said display image no longer shifting in said direction opposite to said specified direction.

2. The method of claim 1 wherein said synchronization of said display image movement rate with said predetermined view port movement rate occurs in a manner such that an object appearing in said display image within said view port appears to be fixed on said display of said computer system.

3. The method of claim 1 wherein said synchronization of said display image movement rate with said predetermined view port movement rate occurs in a manner such that an object appearing in said display image within said view port does not appear to be fixed on said display of said computer system and instead appears to be moving in a direction opposite to said specified direction.

4. The method of claim 1 wherein step a) includes, before said step i) of said view port sliding, the steps of:

for a predetermined period of time and while said user continues to indicate a desire to navigate in said specified direction,

A) said display image shifting within said view port and in a direction opposite to said specified direction;

B) said view port remaining stationary;

after said predetermined period of time and while said user continues to indicate a desire to navigate in said specified direction.

5. The method of claim 1 wherein said user utilizing said input device is accomplished by said user selecting a button adjacent said view port.

6. The method of claim 1 wherein said user utilizing said input device is accomplished by said user selecting a portion of said display image, said portion being indicative of said specified direction.

7. An apparatus for a user of a computer system to navigate within an interface of said computer system, said computer system including a processor, a display and an input device, said interface including a view port having a starting position and containing a display image, said apparatus comprising:

a) means for, if said user indicates a desire to navigate in a specified direction within said interface by utilizing said input device, then

i) sliding said view port in said specified direction and at a predetermined view port movement rate, and

ii) shifting said display image within said view port in a direction opposite to said specified direction and at a rate synchronized with said predetermined view port movement rate;

b) means for, if said view port reaches a view port movement limit, then

i) no longer sliding said view port, and

ii) continuing to shift said display image within said view port in a direction opposite to said specified direction; and

c) means for, if said user indicates a desire to no longer navigate in said specified direction within said interface by utilizing said input device, then

i) returning said view port to said starting position, and

ii) no longer shifting said display image in said direction opposite to said specified direction.

8. The apparatus of claim 7 wherein said means for shifting said display image at a rate synchronized with said predetermined view port movement rate causes an object appearing in said display image to appear to be fixed on said display.

9. The apparatus of claim 7 wherein said means for shifting said display image at a rate synchronized with said predetermined view port movement rate causes an object appearing in said display image to appear to be moving in a direction opposite to said specified direction.

10. The apparatus of claim 7 wherein said user utilizing said input device is accomplished by means for said user to select a button adjacent said view port.

11. The apparatus of claim 7 wherein said user utilizing said input device is accomplished by means for said user to select a portion of said display image, said portion being indicative of said specified direction.

12. An apparatus for a user of a computer system to navigate within an interface of said computer system, said computer system including a processor, a display and an input device, said interface including a view port having a starting position and containing a display image, said apparatus comprising:

a) means for, if said user indicates a desire to navigate in a specified direction within said interface by utilizing said input device, then

i) for a predetermined period of time and while said user continues to indicate a desire to navigate in said specified direction,

A) said display image moving within said view port in a direction opposite to said specified direction;

B) said view port remaining stationary;

ii) after said predetermined period of time and while said user continues to indicate a desire to navigate in said specified direction,

A) sliding said view port in said specified direction at a predetermined view port movement rate, and

B) shifting said display image within said view port in a direction opposite to said specified direction and at a rate synchronized with said predetermined view port movement rate;

b) means for, if said view port reaches a view port movement limit, then

i) no longer sliding said view port, and

ii) continuing to shift said display image within said view port in a direction opposite to said specified direction; and

c) means for, if said user indicates a desire to no longer navigate in said specified direction within said interface by utilizing said input device, then

i) returning said view port to said starting position, and

ii) no longer shifting said display image in said direction opposite to said specified direction.
