1. A computing device comprising:
- a touchscreen including an interactive display, the touchscreen being configured to receive a first input comprising multiple concurrent touchscreen contacts; and
at least one physical processing unit configured to;
identify one or more attributes of individual ones of the multiple concurrent touchscreen contacts received at the touchscreen;
determine an operation to perform on the computing system in response to the first input and the one or more attributes, the operation including toggling visibility of a touch pointer widget adjacent to or surrounding a cursor on the interactive display;
determine a pressure applied to the touchscreen by the first input; and
perform the operation if the pressure applied to the touchscreen by the first input is less than a threshold pressure;
the touchscreen being further configured to receive a second input comprising a touchscreen contact within an area represented by the touch pointer widget on the interactive display, wherein the touchscreen contact is dragged across a screen of the interactive display;
the at least one physical processing unit being further configured to move, in response to the second input, the touch pointer widget and the cursor across the screen of the interactive display in correspondence with the touchscreen contact being dragged across the screen;
the touchscreen being further configured to receive a third input comprising another touchscreen contact (i) within the area represented by the touch pointer widget on the interactive display and (ii) on a control button of the touch pointer widget; and
the at least one physical processing unit is being further configured to perform, in response to the third input, a selection operation by the cursor.

Abstract
A tablet PC having an interactive display, which is touchscreen enabled, may be enhanced to provide a user with superior usability and efficiency. A touchscreen device may be configured to receive multiple concurrent touchscreen contacts. The attributes of the multiple concurrent touchscreen contracts may be mapped to operations performed on the computing device. As a result, a user can trigger the execution of the toggle accessibility aid operation and the screen rotation operation with greater convenience. Moreover, the tablet PC may be configured to map an operation to a hand gesture or input.

8. A computing device comprising:
-
a touchscreen including an interactive display, the touchscreen being configured to receive a gesture comprising multiple concurrent touchscreen contacts; and at least one physical processing unit configured to; process the gesture to identify one or more attributes of individual ones of the multiple concurrent touchscreen contacts; and perform an operation in response to receiving and processing the gesture, the operation including toggling visibility of a touch pointer widget adjacent to or surrounding a pointer element on the interactive display; the touchscreen being further configured to receive an input comprising a touchscreen contact (i) within an area represented by the touch pointer widget on the interactive display and (ii) on a control button of the touch pointer widget; and the at least one physical processing unit being further configured to perform, in response to the input, a selection operation by the pointer element. - View Dependent Claims (9, 10, 11, 12)

13. A computing device comprising:
-
a pressure sensitive touchscreen including an interactive display, the pressure sensitive touchscreen being configured to receive a gesture comprising multiple concurrent touchscreen contacts; and at least one physical processing unit configured to; determine a pressure applied to the pressure sensitive touchscreen by the multiple concurrent touchscreen contacts of the gesture; perform a first operation if the pressure applied to the pressure sensitive touchscreen by the multiple concurrent touchscreen contacts is applied at a first pressure, the first operation including toggling visibility of a touch pointer widget on the interactive display; and perform a second operation if the pressure applied to the pressure sensitive touchscreen by the multiple concurrent touchscreen contacts is applied at a second pressure that is different than the first pressure, the second operation including toggling visibility of a soft keyboard widget on the interactive display. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
