METHOD AND SYSTEM FOR DISPLAYING SPEED INFORMATION
First Claim
1. A method for displaying speed information, the method comprising:
- acquiring a current geographical location of a portable electronic device or a vehicle;
obtaining road data for the current geographical location of the portable electronic device or the vehicle, wherein the road data includes a posted speed limit;
displaying a first graphical feature indicating the posted speed limit;
determining an actual current speed of the portable electronic device or the vehicle;
displaying a second graphical feature indicating the actual current speed of the portable electronic device or the vehicle, wherein the second graphical feature has a size that corresponds to the actual current speed;
increasing the size of the second graphical feature with an increase of the actual current speed; and
decreasing the size of the second graphical feature with a decrease of the actual current speed.

Abstract
A system for displaying speed information for a vehicle includes a speed measuring device configured to obtain an actual current speed, a display for displaying speed information to an operator, and a controller. The controller acquires a geographical location, obtains road data including a posted speed limit for the geographical location, and causes displaying a first graphical feature indicating the posted speed limit and a second graphical feature indicating the actual current speed. For example, the first graphical feature is in the form of a ring, while the second graphical feature is a circle centered within the first graphical feature. A size of the second graphical feature corresponds to the actual current speed and dynamically changes with the change of the actual current speed. Thus, the size of second graphical feature increases with the increase of actual current speed and decreases with the decrease of actual current speed.
