Systems and methods for enabling a Graphical User Interface (GUI) manipulation using hand gestures over a hovering keyboard are described. In some embodiments, an Information Handling System (IHS) may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the IHS to: detect a hand gesture using proximity sensors disposed on a hovering keyboard coupled to the IHS, and manipulate a task map rendered on a display coupled to the IHS in response to the detection.

A tactile touch sensor (TTS) system and method allowing physical augmentation of a high-resolution touch sensor array (TSA) is disclosed. Physical augmentation is accomplished using a TSA physical overlay (TPO) placed on top of the TSA. The TPO is constructed to transmit forces to the underlying TSA. Force transmission is accomplished by either using a flexible overlay or with a rigid mechanical overlay that transmits user forces exerted on the overlay to the underlying TSA. Incorporation of TPO identifiers (TPI) within the TPO permits identification of the TPO by a TPO detector (TPD) allowing operational characteristics of the TSA to be automatically reconfigured to conform to the currently applied TPO structure by a user computing device (UCD). The UCD may be configured to automatically load an appropriate application software driver (ASD) in response to a TPI read by the TPD from the currently applied TPO.
