Abstract
A navigation device with improved zoom functions is disclosed. The navigation device is generally operable to display a map with varying magnifications and perspectives to enable a user to increase or decrease magnification and perspective without creating a substantial and immediate change in perspective. Such a configuration reduces user confusion due to the elimination of substantial changes in perspective during magnification and demagnification.
Claims31
A device comprising:
- a processor operable to acquire data corresponding to a map;
- and
- a display coupled with the processor, the processor and display operable to—
- display the map with a first magnification and a first perspective, and in response to a magnification request—
- display the map with a second magnification and a second perspective, the second magnification and the second perspective being greater than the first magnification and the first perspective, and
- display the map with a third magnification and a third perspective, the third magnification and the third perspective being greater than the second magnification and the second perspective.
3 more elements
A navigation device comprising:
- a processor operable to—
- acquire data corresponding to a map including a current geographic location of the device, and
- receive at least one magnification request;
- a location determining component coupled with the processor and operable to facilitate determination of the current geographic location of the device;
- a user interface coupled with the processor and operable to receive the at least one magnification request from a user;
- and
- a display coupled with the processor, the processor and display operable to—
- display the map with a first magnification and a first perspective,
- in response to a first magnification request—
- display the map with a second magnification and a second perspective, the second magnification and the second perspective being greater than the first magnification and the first perspective, and
- in response to a second magnification request—
- display the map with a third magnification and a third perspective, the third magnification and the third perspective being greater than the second magnification and the second perspective.
9 more elements
A method of displaying a map, the method comprising the steps of:
- (a) displaying the map utilizing a first magnification and a first perspective;
- (b) receiving a magnification request;
- (c) in response to the magnification request, displaying the map with a second magnification and a second perspective, the second magnification and the second perspective being greater than the first magnification and the first perspective;
- and
- (d) in response to the magnification request, displaying the map with a third magnification and a third perspective, the third magnification and the third perspective being greater than the second magnification and the second perspective.
