Keyboard alignment device

DETAILED DESCRIPTION Tool acquisition (wherein the tool is to be securely controlled within the structure of the hand) preparatory to tool usage requires that this appendage be adapted for seizing and grasping.
The essential characteristics of prehensility is that we do have an anatomically opposable thumb and, with some variations, it functions with a ventral-to-ventral surface apposition of the thumb to the finger(s).
Nonprehensile tool usage involves pushing or in some other manner moving a tool without the tool being held in control within the hand, and does not possess the same level of precision, sensitivity, and gentle control that is attributable to prehensile activity.
The usage of traditional flat/rectangular computer keyboards mandates that the hands be fully pronated into the horizontal plane and ulnar-deviated outward at the hand-wrist junction, and therein lies a major cause of repetitive strain injuries.
Tool usage within this environment would have to be considered nonprehensile, because the percussion of each key is executed in a direction which is essentially away from the action and the range-of-motion of the opposable thumb.
It has been beneficially recognized that if the keyboard is reshaped into a biometric form incorporating a moderate V-shape and moderate center-peaking, these attributes permit a relatively straight hand-wrist junction and allow for less pronation of the hands into the horizontal plane.
By placing a standard keyboard on the keyboard alignment device of the present invention, the keyboard operation by the user begins to simulate prehensile tool usage and facilitates the action of the opposable thumb in moving toward the fingers (and, to a lesser extent, the fingers moving toward the opposable thumb).
Prehensile activity affords multiple choices of power gripping or precision gripping in holding tools, and thereby provides much finer tool usage control.
Working with traditional flat/rectangular keyboards classifies as nonprehensile activity and therefore requires greater visual dependency and quicker onset of asthenopia, stress and fatigue
