Abstract

A keyboard includes rows of keys defining a keyboard axis and side borders of the keyboard, the keyboard axis disposed mediate the side borders of the keyboard, the rows of keys disposed in series with each other along the keyboard axis, and the keyboard axis being disposed at an acute or obtuse angle relative to a user of the keyboard and being generally aligned along a length of an arm of the user holding the keyboard. Each key may be also defined by a unique region of numeric values or a unique region of color pixels allowing ease in changing keyboard location, size and orientation.

Claims

1. A device comprising a processor executing a machine executable software code, a memory, a rectangular display screen with orthogonally disposed edges defining a quadrilateral shaped surface of said display screen and a diagonal virtual keyboard displayable on said display screen surface during use of said device, said diagonal virtual keyboard comprising:

arc shaped rows of virtual keys defining a keyboard axis, a keyboard diagonal sized and oriented to span and utilize area between opposite corners of said display screen surface and side borders of said diagonal virtual keyboard so that all alphabetical keys are displayed on said display screen surface;

said keyboard axis running through a point formed, external to one side border of said device, by an intersection of first and second secondary axes, wherein one of said first and second secondary axes is disposed inwardly from and parallel to a respective side edge of said display screen surface, wherein

an angle of an arc, defined by said first and second secondary axes, being less than ninety (90) degrees and wherein

said arc shaped rows of keys being disposed in series with each other along said keyboard axis and within side edges of said display screen surface during use of said diagonal virtual keyboard;

said keyboard axis being disposed at an acute or obtuse angle relative to a user of said diagonal virtual keyboard and being generally aligned along a length of an arm of the user holding said device; and

said diagonal keyboard scalable, during use of said device, proportionally in both height and width to maintain same aspect ratio.

2. A device comprising a processor executing a machine executable software code, a memory, a rectangular display screen with orthogonally disposed edges defining a quadrilateral shaped surface of said rectangular display screen and a diagonal virtual keyboard displayable on said rectangular display screen surface during use of said device, said diagonal virtual keyboard comprising:

arc shaped rows of virtual keys defining a keyboard axis, a keyboard diagonal and side borders of said diagonal virtual keyboard, a height of said diagonal virtual keyboard being different than a width thereof during use of said diagonal virtual keyboard;

said keyboard axis runs through a point formed, external to one side border of said device, by an intersection of first and second secondary axes, wherein one of said first and second secondary axes is disposed inwardly from and parallel to a respective side edge of said rectangular display screen;

said arc shaped rows of keys disposed in series with each other along said keyboard axis and within side borders of said rectangular display screen surface, wherein said side borders of said diagonal virtual keyboard do not extend beyond said side borders of said rectangular display screen surface during use of said diagonal virtual keyboard when said point having said keyboard axis therethrough is disposed external to said one side border of said device and wherein all alphabetical keys are displayed on said rectangular display screen surface; and

said diagonal virtual keyboard scalable, during use of said device, proportionally in both height and width to maintain same aspect ratio.

3. A diagonal virtual keyboard configured to be displayed on a rectangular display screen surface, said diagonal virtual keyboard comprising:

arc shaped rows of virtual keys defining a keyboard axis, a keyboard diagonal and side borders of said diagonal virtual keyboard, said side borders defining a rectangular surface, said keyboard diagonal spanning a pair of opposite corners of said rectangular surface during use of said diagonal virtual keyboard;

said arc shaped rows of keys disposed in series with each other along said keyboard axis, wherein said side borders of said diagonal virtual keyboard do not extend beyond said side borders of said display screen surface during use of said diagonal virtual keyboard and wherein all alphabetical keys are displayed on said display screen surface;

a height of said diagonal virtual keyboard being different than a width and configured to be scalable, during use of said device, proportionally in both height and width to maintain same aspect ratio.
