Patent ID: 7623960

Claim:
A system for performing 4-dimensional navigation within a vehicle, comprising: means for receiving navigation information; a processing unit coupled to the means for receiving navigational information, said processing unit operable to: estimate a range of arrival times to at least one predetermined location from said navigation information, compare the range of estimated arrival times for said at least one predetermined location with a predetermined time of arrival associated with said at least one predetermined location, and determine if said range of estimated arrival times includes said predetermined time of arrival; generate display control signals that include signals delimiting said range of estimated arrival times and signals delimiting a current speed; and a display unit coupled to receive the display control signals from said processing unit, said display unit including an electronic display and being responsive to said display control signals that also render said range of estimated arrival times at a specific position on said electronic display and render said current speed indicator on said display such that the position of the speed indicator on the display conditionally moves within and relative to the position of said range of estimated arrival times on the display.
