In tasks where two non-discreet controls need to be operated simultaneously, like moving two sliders or turning two dials representing various values, the task is difficult or impossible with just one pointer. For example, in an audio application, dynamically lower the left channel while raising the right channel audio. What is meant by non-discreet is that the changes to the control do not happen in fixed steps (i.e analog like). Today the user would be forced to use the pointer and keyboard together, but the keyboard would not be able to give the granularity of control needed by some users. The keyboard can only operate in "digital" mode where each keypress indicates one event (increment).

Change of analog value

Enable two active pointers on the screen. One pointer can change one analog value while the other pointer changes the other analog value. These changes can happen simultaneously. Because a pointer can be moved in a variable manner, the user can accurately modify the control to the desired result.

Two active pointers are needed at the same time, each having its own input device. The user can use one input control device to modify one analog value represented by one GUI component while the second pointer modifies a different analog value represented by a different GUI component. This allows the user to accomplish something which is currently impossible with only one pointer combined with a keyboard.
