Virtual input devices created by touch input

A computer-readable storage medium having computer-executable instructions for creating a virtual input device in response to a touch input, comprising:

• determining when a portion of a hand is detected by a touch input device;
• wherein a portion of the hand includes at least two detected fingers and a detected palm of the hand;
• automatically determining a size of the hand by determining a finger length and a location of a palm of the hand;
• creating the virtual input device that is sized based on the determined size of the hand;
• wherein an inner area of the virtual input device is sized to contain at least the fingers of the hand;
• displaying a graphical representation of the virtual input device;
• wherein a majority of the virtual input device is displayed beneath the hand;
• receiving user input from the virtual input device through an interaction with the hand with the virtual input device;
• wherein a position of the display of the virtual input device moves in response to a movement of the hand and wherein movement of the virtual input device changes a location of a cursor on a display;
• and
• removing the virtual input device when the hand becomes undetected by the touch input device.

A system for utilizing a virtual input device created in response to touch inputs, comprising:

• a touch surface that is configured to receive multiple touches;
• a processor and a computer-readable medium;
• an operating environment stored on the computer-readable medium and executing on the processor;
• and
• a touch manager operating under the control of the operating environment and operative to:
• determining when a portion of a hand is detected on the touch surface;
• wherein a portion of the hand includes at least two detected fingers and a detected palm of the hand;
• automatically determining a size of the hand;
• creating the virtual input device that is sized based on the determined size of the hand;
• wherein an inner area of the virtual input device is sized to contain at least a majority of the fingers of the hand;
• displaying a graphical representation of the virtual input device on the touch surface;
• wherein a majority of the virtual input device is displayed beneath the hand;
• receiving user input from the virtual input device through an interaction with the hand with the virtual input device;
• wherein a position of the display of the virtual input device moves in response to a movement of the hand and wherein movement of the virtual input device changes a location of a cursor on a display;
• and
• removing the virtual input device when the hand becomes undetected on the touch surface.
