Keyboard with touch sensitive element
First Claim
1. An input device comprising:
- one or more processors;
a plurality of keys including;
a controller key; and
one or more input keys; and
a first sensor system controlled by the processor and configured to detect a location of an object in three-dimensional (3D) space configured over and not touching a top surface of the one or more input keys while the controller key is activated; and
a second sensor system controlled by the one or more processors and configured to detect a location of the object touching the top surface of the one or more input keys while the controller key is activated,wherein the first sensor system detects at a first sensitivity level, andwherein the second sensor system detects at a second sensitivity level different from the first sensitivity level, andwherein the first and second sensor systems are each configured to generate a signal corresponding to a position of the object relative to the one or more input keys, the signal configured to control a cursor on a display according to the corresponding sensitivity level.

Abstract
Some embodiments include an input device comprising a processor and a key frame having a plurality of keys disposed therein and a motion sensor controlled by the processor and disposed below the key frame. The plurality of keys includes a controller key and one or more input keys, where the motion sensor generates a signal corresponding to a movement of an object along the surface of the one or more input keys when the controller key is activated, where the signal can be used to control a cursor on a display. Each of the one or more input keys generates an input function when activated and can include one or more of an alphanumeric input, arrow key input, or function key input. In some cases, the controller key can be one or more of a shift key, control key, windows key, command key, alt key, dedicated controller key, or user-assigned key.

6. A method for controlling a keyboard having a controller key and one or more input keys the method comprising:
-
receiving, by one or more processors, a control signal indicating that the controller key on the keyboard is activated; receiving, by the one or more processors while the controller key is activated, a first input signal from a first sensor system configured to detect a location of an object in 3D space over and not touching a top surface of the input keys; receiving, by the one or more processors while the controller key is activated, a second input signal from a second sensor system configured to detect a location of the object touching the top surface of the one or more input keys; and controlling a cursor on a display based on the received first and second input signals. - View Dependent Claims (7, 8, 9)

10. A system comprising:
-
one or more processors; a keyboard having a controller key and a plurality of input keys, the keyboard controlled by the one or more processors; a first sensor system controlled by the one or more processors and configured to detect a location of an object in 3D space over a top surface of the plurality of input keys; a second sensor system controlled by the one or more processors and configured to detect a location of the object touching the top surface of the plurality of input keys; one or more non-transitory computer-readable storage mediums containing instructions configured to cause the processor to perform operations including; receiving, from the keyboard, a control signal indicating that the controller key is activated; receiving, by the one or more processors while the controller key is activated, a first input signal from a first sensor system corresponding to the detected location of the object in 3D space; receiving, by the one or more processors while the controller key is activated, a second input signal from a second sensor system corresponding to the location of the object touching the top surface of the plurality of input keys; and controlling a cursor on a display based on the received first and second input signals. - View Dependent Claims (11, 12, 13)
