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. |
