Abstract
An information handling system keyboard has optical sensors disposed under transparent windows of plural adjacent keys to sense gestures performed above the keyboard. A capacitive touch detection surface under the plural keys detects by proximity sensing finger touches at the keys. A user interface presents the gesture input value and the finger touch values to an end user, such as by highlighting keys on a keyboard visual image.
Claims20
An information handling system comprising:
- a housing;
- a processor coupled in the housing and operable to execute instructions to process information;
- a memory coupled in the housing and interfaced with the processor, the memory operable to store the instructions and information;
- and
- a keyboard interfaced with the processor, the keyboard having plural keys each key accepting an end user press as an input, the keyboard having a set of plural optical sensors positioned at adjacent of the plural keys, the plural optical sensors having a field of view above the keyboard and operable to detect hand gestures above the keyboard as key inputs.
