Claim 2

Method of controlling a cursor for an in-car computing device comprising a display screen for displaying information, option menu items and a cursor, and a control element for moving said cursor and for selecting an option menu items, the method comprising the steps: detecting a display region of a predetermined information on the display screen, detecting a distance between said cursor and an adjacent display region, and automatically applying a force to said control element if the distance to a display region falls below a predetermined value so as to move the cursor on this display region.

Claim 3

Method of claim 1 , characterized in that said information displayed on said display screen are streets which are part of a map detail of a navigation system.

Claim 4

Method of claim 1 , characterized in that said information displayed on the display screen are hyperlinks of an Internet page.

Claim 5

Method of claim 2 , characterized in that upon manual actuation of the control element in one of said two directions (x-, y-direction) for moving said cursor, said third means applies an operating force to said control element to move said cursor in the other direction in order to hold said cursor on the display region.

Claim 6

Method of any of claims 2 , characterized in that a force counteracting the manual operating force is applied to said control element if the cursor reaches the margin of the display screen.

Claim 7

Method of claim 5 , characterized in that said map detail displayed on the display screen is changed if the counteracting force is overcome by the user.

Claim 8

Method of claim 2 , characterized in that the magnitude of the force depends on the street type.

Claim 9

Method of claim 2 , characterized in that the internet page displayed on the display screen is turned over if the counteracting force is overcome by the user.

Claim 10

Method of claim 3 , characterized in that said information displayed on the display screen are option menu items.

Claim 11

Method of controlling a cursor for an in-car computing device comprising a display screen for displaying a map with streets, option menu items and a cursor, and a control element for moving said cursor and for selecting an option menu item, the method comprising the steps: detecting a display region of a street on the display screen, detecting a distance between said cursor and an adjacent display region, and automatically applying a force to said control element if the distance to a display region falls below a predetermined value so as to move the cursor on this display region, wherein upon manual actuation of the control element in one of said two directions (x-, y-direction) for moving said cursor, said third means applies an operating force to said control element to move said cursor in the other direction in order to hold said cursor on the display region.

Claim 12

Method of controlling a cursor for an in-car computing device comprising a display screen for displaying a map with streets, option menu items and a cursor, and a control element for moving said cursor and for selecting an option menu item, the method comprising the steps: detecting a display region of a street on the display screen, detecting a distance between said cursor and an adjacent display region, and automatically applying a force to said control element if the distance to a display region falls below a predetermined value so as to move the cursor on this display region, wherein upon manual actuation of the control element in one of said two directions (x-, y-direction) for moving said cursor, said third means applies an operating force to said control element to move said cursor in the other direction in order to hold said cursor on the display region.

Claim 13

In-Car computing device comprising a computer unit, a display screen for displaying information, a cursor and option menus with individual option menu items, said information displayed on the display being streets, a control element for moving said cursor on the display screen two-dimensionally and for selection option menu items, first means for detecting a display region of predetermined information on the display, second means for determining a pull-in region of a predetermined size for a display region, and third means for applying an operating force to said control element when the cursor is in said pull-in region such that said cursor is moved into the corresponding display region, wherein upon actuation of the control element in one of said two directions (x-, y-direction) for moving said cursor, said third means applies an operating force to said control element to move said cursor in the other direction in order to hold said cursor on the display region, the magnitude of said operating force depending on the street-type.

Claim 14

In-Car computing device comprising a computer unit, a display screen for displaying information, a cursor and option menus with individual option menu items, said information displayed on the display being streets, a control element for moving said cursor on the display screen two-dimensionally and for selection option menu items, first means for detecting a display region of predetermined information on the display, second means for determining a pull-in region of a predetermined size for a display region, and third means for applying an operating force to said control element when the cursor is in said pull-in region such that said cursor is moved into the corresponding display region, wherein upon actuation of the control element in one of said two directions (x-, y-direction) for moving said cursor, said third means applies an operating force to said control element to move said cursor in the other direction in order to hold said cursor on the display region, the magnitude of said operating force depending on the street-type.

Claim 15

In-Car computing device comprising a computer unit, a display screen for displaying information, a cursor and option menus with individual option menu items, said information displayed on the display being hyperlinks, a control element for moving said cursor on the display screen two-dimensionally and for selecting option menu items, first means for detecting a display region of predetermined information on the display, second means for determining a pull-in region of a predetermined size for a display region, and third means for applying an operating force to said control element when the cursor is in said pull-in region such that said cursor is moved into the corresponding display region, wherein said third means applies to said control element a force counteracting said operating force, when said cursor reaches the margin of the display screen during operation.

Claim 16

In-Car computing device comprising a computer unit, a display screen for displaying information, a cursor and option menus with individual option menu items, said information displayed on the display being hyperlinks, a control element for moving said cursor on the display screen two-dimensionally and for selecting option menu items, first means for detecting a display region of predetermined information on the display, second means for determining a pull-in region of a predetermined size for a display region, and third means for applying an operating force to said control element when the cursor is in said pull-in region such that said cursor is moved into the corresponding display region, wherein said third means applies to said control element a force counteracting said operating force, when said cursor reaches the margin of the display screen during operation.
