Abstract

Systems and methods are disclosed for rendering soft keyboard layouts for a touchscreen display that are based on the unique finger characteristics of different individual users by taking into account and accommodating unique hand characteristics of different individual users and/or different user preferences for positioning of the user'"'"'s two hands on the touch screen. The disclosed systems and methods may be implemented in one example to render a custom soft keyboard layout for a user on a touch screen display having a touch display area that is larger than a standard keyboard layout.

Claims

1. An information handling system, comprising:

a touch screen display device;

at least one processing device coupled to provide display data for controlling display of visual images on the touch screen display device, the processing device also being coupled for receiving data signals representative of touched areas of the touch screen display device;

where the at least one processing device is configured to alternatively render at least two different soft keyboard layouts on the touch screen display, the two different soft keyboard layouts comprising;

a single unitary soft keyboard for accepting keyboard input from each of a left hand and a right hand of a given user, and

a segmented non-unitary soft keyboard having separated different portions with no keyboard portion therebetween, a first one of the separate different portions for accepting input from fingers of a left hand of a user and a second different one of the separate different portions for accepting input from fingers of a right hand of a given user;

where the at least one processing device is further configured to determine which of the at least two soft keyboard layouts to render on the touch screen display device based on a measured distance between a first location on the touch screen touched by at least one finger of a user'"'"'s left hand and a second location on the touch screen touched by at least one finger of a user'"'"'s right hand, and to render this determined soft keyboard layout on the touch screen display device; and

where the at least one processing device is further configured to compare the measured distance between the first location on the touch screen touched by at least one finger of a user'"'"'s left hand and the second location on the touch screen touched by at least one finger of a user'"'"'s right hand to a pre-designated value; and

then;

always render the segmented non-unitary soft keyboard layout on the touch screen display device and never render the single unitary soft keyboard layout on the touch screen display device when the measured distance between the first and second locations is greater than or equal to the pre-designated value, and

where the at least one processing device is further configured to;

first detect and respond to application of only an index finger of the user'"'"'s left hand to the first location on the touch screen and an index finger of the user'"'"'s right hand to the second location on the touch screen without application of other fingers of the user'"'"'s left hand and right hand by determining which of the at least two soft keyboard layouts to render on the touch screen display device based on the measured distance between the first location on the touch screen touched by only the index finger of the user'"'"'s left hand and the second location on the touch screen touched by only the index finger of the user'"'"'s right hand, and to render this determined soft keyboard layout on the touch screen display device, and

then prompt the user to apply the remaining six fingers of the user'"'"'s left and right hands to the touch screen when the measured distance between the first and second locations is less than the pre-designated value, and

then detect and respond to application of the remaining six fingers of the user'"'"'s left and right hands to the touch screen when the measured distance between the first and second locations is less than the pre-designated value by then resizing the outer dimensions of the rendered single unitary soft keyboard layout on the touch screen display device based on a measured distance between separate locations on the touch screen touched by at least two different fingers on the same left or right hand of a user.
