Navigation system character input device
First Claim
1. A method for activating a symbol from a plurality of symbols in a graphical user interface, said method comprising the steps of;
- a.) initially displaying a plurality of groups and a plurality of symbols including a first symbol in each group, said plurality of groups including a first group, said plurality of groups displayed around a start position on a display device, each of said groups in a unique pre-determined direction relative to the start position;
b.) transmitting a first directional signal associated with one of the unique predetermined directions from a directional input device;
c.) activating the first group in response to the first directional signal;
d.) transmitting a second directional signal from the directional input device;
e.) activating the first symbol of the first group in response to the second directional symbol.

Abstract
The invention relates to a method and a device for a graphical user interface for a navigation system. The graphical user interface includes a display having several groups of symbols with each group arranged in a unique pre-determined direction relative to a start position. A user manipulatable directional input device permits a user to select any one of the groups with a single keystroke. Once a group has been selected, the directional input device permits a user to activate any one of the symbols within a group with a single keystroke. An activated symbol can be selected with one keystroke by the user. Selection of a symbol then re-activates the start position.

15. A graphical user interface comprising:
-
a display device initially displaying a plurality of groups and a plurality of symbols in each group, each group located in one of a plurality of pre-determined directions relative to a start position; said plurality of symbols of each of said groups arranged about a central position in each of said groups; an input device connected to said display device, said input device having a selection signal and a plurality of directional output signals, each of said plurality of output signals associated with one of said plurality of pre-determined directions; and each group activatable in response to one of said plurality of output signals, each symbol within an activated group of said plurality of groups activatable in response to one of said plurality of output signals, an activated symbol selectable in response to said selection signal. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
