FUSION KEYBOARD
First Claim
1. A keyboard comprising:
- a plurality of depressible keys, wherein at least one key of the plurality of depressible keys is a dual-purpose key configured to be depressed a first distance to a first level and a second distance to a second level;
a plurality of switch sensors configured to detect a depression of a key of the plurality of depressible keys, wherein at least one switch sensor of the plurality of switch sensors is configured to detect the at least one dual-purpose key being depressed the first distance to the first level and the at least one dual-purpose key being depressed the second distance to the second level; and
an array of capacitive sensors configured to detect a touch event on a surface of one or more of the plurality of depressible keys.

Abstract
Touch sensitive mechanical keyboards for detecting touch events and key depressions on the keyboard are provided. The keyboard can include a set of individually depressible mechanical keys having a touch sensitive area located on their surface. A touch sensor can be included to detect touch events on the surface of the keys. A keypad can also be included to detect a depression of the mechanical keys. One or more of the depressible mechanical keys can be multi-purpose keys capable of being depressed to multiple levels. The touch sensitive mechanical keyboard can receive key depression input, touch event input, or combinations thereof at the same time. The touch sensitive mechanical keyboard can further include a processor for distinguishing detected touch events from detected key depressions. The processor can generate a key depression command or a touch event command in response to the detected touch events and key depressions.

13. A method for generating a keyboard command signal, the method comprising:
-
monitoring a plurality of depressible keys for a depression of a key of the plurality of depressible keys, wherein at least one key of the plurality of depressible keys is a multi-purpose key being monitored to detect the at least one multi-purpose key being depressed a first distance to a first level and the at least one multi-purpose key being depressed a second distance to a second level; monitoring the plurality of depressible keys for a touch event on a surface of one or more of the plurality of depressible keys; and generating a command signal based on the monitoring of the plurality of depressible keys for the depression of the key of the plurality of depressible keys and the monitoring of the plurality of depressible keys for the touch event on the surface of one or more of the plurality of depressible keys. - View Dependent Claims (14, 15, 16, 17)

18. A method for generating keyboard command signals, the method comprising:
-
receiving a first input, wherein the first input comprises one of a depression of a first key of a plurality of depressible keys or a touch event on a surface of the first key of the plurality of depressible keys; receiving a second input, wherein the second input comprises one of a depression of a second key of the plurality of depressible keys or a touch event on a surface of the second key of the plurality of depressible keys; determining whether the first input comprises the depression of the first key of a plurality of depressible keys or the touch event on the surface of the first key of the plurality of depressible keys; determining whether the second input comprises the depression of the second key of a plurality of depressible keys or the touch event on the surface of the second key of the plurality of depressible keys; generating a first command signal based on the determining whether the first input comprises the depression of the first key of a plurality of depressible keys or the touch event on the surface of the first key of the plurality of depressible keys; and generating a second command signal based on the determining whether the second input comprises the depression of the second key of a plurality of depressible keys or the touch event on the surface of the second key of the plurality of depressible keys. - View Dependent Claims (19, 20, 21, 22, 23, 24)
