A navigation device has a route re-calculation function. This is activated by the user touching the screen to task away from the normal navigation map mode to a menu screen which displays multiple types of route re-calculation options.

Navigation device and method for displaying alternative routes

A navigation device programmed with a map database and software that enables a route to be planned between two user-defined places. The device may be further programmed to be able to display on a touch sensitive display a main navigation mode screen showing a map and to allow a user to input destination address information using a virtual keyboard whose keys are sized to allow reliable finger activation. The device is especially advantageous for an in-car navigation device since it allows the user to easily and reliably input address information, even whilst the device is mounted in a vehicle.

Navigation device with touch screen

An in-car navigation device has a route preview or simulation function. The name of the actual road along which the vehicle is simulated as moving is also displayed, just as it would be if the vehicle were actually travelling along the route. The status bar, or actually on the road itself. This 'demonstrate route' function is achievable because the device stores a database sequence of road names, together with the vectors and actions which define the roads of the calculated route (this route has been fully calculated in advance and stored in device memory). Records in this database that define the route can then be sequentially selected (say simulating progress at a rate that allows the entire journey to be completed in 15 seconds) and the device can then display simulated progress of the car along the vectors which define the roads of the calculated route on the map image.

Navigation device and method for displaying simulated navigation data

A navigation device is programmed to be able to associate any function, belonging to a core set of functions, with a non-overlapping touch input zone that is large enough to be reliably activated using a finger. Hence, the present invention is predicated on the insight that it is possible to identify a set of core functions and to then enable all of them to be reliably selected/activated by a finger touch to a touch input zone large enough for reliable activation. This is especially advantageous for an in-car navigation device in which the core functions are those functions that are likely to be activated by a driver whilst still driving.
