Human interfaces for vehicles, homes, and other applications
The disclosed invention concerns novel methods and apparatus for controlling computer systems using both touch screens and physical controls, and is useful in many applications such as vehicles, homes and the like. Physical controls and virtual displayed controls on single and multipoint touch screens are used, separately or in combination to enable higher visibility and understanding of control information and easier operation of controls, particularly useful in stressful situations.
1 . Tactile control means comprising:
a computer;
a display means having a screen member, said display controlled by said computer;
means for tactile relation of a finger touch to said member;
sensing means for determining a characteristic of said touch on said member; and
means for changing said display or another operation controlled by said computer as a function of said sensed touch.
2 . Apparatus according to claim 1 wherein said means for tactile relation can be felt by said user.
3 . Apparatus according to claim 1 wherein said means for tactile relation is in a fixed location on the outer surface of said member.
4 . Apparatus according to claim 1 wherein said means for tactile relation is in a temporary location on the outer surface of said member.
5 . Apparatus according to claim 1 wherein said means for tactile relation provides a resistance to movement of said finger on said member.
6 . Apparatus according to claim 1 wherein said means for tactile relation provides a programmable resistance or other indication.
7 . Apparatus according to claim 1 wherein said means for tactile relation comprises a local protrusion or indentation of the screen surface.
8 . Apparatus according to claim 1 wherein said local protrusion or indentation is less than 0.020 inches in height or depth.
9 . Apparatus according to claim 1 wherein a line of action is represented by said means for tactile relation.
10 . Apparatus according to claim 1 wherein said means for tactile relation comprises a programmable generator of an acoustic pulse or wave in said screen member or on the surface of said screen member.
11 . Apparatus according to claim 1 wherein said means for tactile relation comprises a distortion of said screen member.
12 . Apparatus according to claim 1 wherein said screen member is an overlay on a permanent screen of said display.
13 . Apparatus according to claim 1 wherein said sensing means is optically based.
