Implementations also can be responsive to a user's finger position or movement in the left-right and forward-backward directions. Implementations can also use HDTP or other user interface technology implemented on the back of a mouse. Also, the interactive map imaging application may use a connection over the internet or other network. ## Claims ### Claim 1 A method for controlling an interactive map application, the method comprising: configuring a user interface touch sensor to be responsive to at least one angle of contact with at least one finger, the finger belonging to a human user of a computing device and the user interface touch sensor in communication with an operating system of the computing device; measuring at least one change in at least one angle of the position of the finger with respect to the surface of the touch sensor to produce measured data; performing real-time calculations on the measured data to produce a measured-angle value; and using the measured-angle value to control the value of at least one user interface parameter of an interactive map application; wherein at least one aspect of the interactive map application changes responsive to the angle of the position of the finger with respect to the surface of the touch sensor. ### Claim 2 (depends on 1) The method of claim 1 wherein the at least one aspect of the interactive map application comprises control of the observation viewpoint of the map. ### Claim 3 (depends on 1) The method of claim 1 wherein the at least one aspect of the interactive map application comprises control of the graphically rendered map. ### Claim 4 (depends on 1) The method of claim 1 wherein the interactive map application comprises a network link over a network. ### Claim 5 (depends on 1) The method of claim 1, wherein the user interface touch sensor is configured as a touchscreen. ### Claim 6 (depends on 1) The method of claim 1 wherein the touch sensor comprises a High Dimensional Touchpad (HDTP). ### Claim 7 (depends on 1) The method of claim 1, wherein the at least one finger angle comprises the pitch of the finger with respect to the touch sensor. ### Claim 8 (depends on 1) The method of claim 1, wherein the at least one finger angle comprises the roll of the finger with respect to the touch sensor. ### Claim 9 (depends on 1) The method of claim 1, wherein the at least one finger angle comprises the yaw of the finger with respect to the touch sensor. ### Claim 10 (depends on 1) The method of claim 1, wherein the user interface touch sensor is additionally configured to be responsive to the left-right position of the finger on the touch sensor. ### Claim 11 (depends on 1) The method of claim 1, wherein the user interface touch sensor is additionally configured to be responsive to the forward-backward position of the finger on the touch sensor. ### Claim 12 (depends on 1) The method of claim 1, wherein the user interface touch sensor is additionally configured to be responsive to at least one gesture comprising changes to left-right position of the finger on the touch sensor. ### Claim 13 (depends on 1) The method of claim 1, wherein the user interface touch sensor is additionally configured to be responsive to at least one gesture comprising changes to forward-backward position of the finger on the touch sensor. ### Claim 14 (depends on 1) The method of claim 1, wherein the user interface touch sensor is additionally configured to be responsive to heave gestures comprising changes to pressure applied by the finger to the touch sensor. ### Claim 15 (depends on 1) The method of claim 1, wherein the user interface touch sensor is additionally configured to be responsive to gestures comprising changes to pressure applied by the finger to the touch sensor. ### Claim 16 (depends on 1) The method of claim 1, wherein the user interface touch sensor is further configured to be responsive to simultaneous changes in at least two of finger roll angle, finger pitch angle, finger yaw angle, and finger downward pressure. ### Claim 17 (depends on 1) The method of claim 1, wherein the computing device comprises a mobile device. ### Claim 18 (depends on 1) The method of claim 1, wherein the computing device is comprised by a mobile device. ### Claim 19 (depends on 1) The method of claim 1, wherein the speed of the change of the finger angle is further used to control an aspect of the interactive map application. ### Claim 20 (depends on 1) The method of claim 1, wherein at least one finger angle is used in a natural metaphor to an aspect of the interactive map application.
