SIMULATING A MULTI-TOUCH SCREEN ON A SINGLE-TOUCH SCREEN
First Claim
1. A method for interacting with a single-touch screen, the method comprising:
- beginning in a single-touch state;
entering a simulated multi-touch state, wherein entering the simulated multi-touch state is triggered by receiving touch input from the single-touch screen, the triggering touch input defining a reference point on the single-touch screen;
while in the simulated multi-touch state, receiving further touch input from the single-touch screen;
performing a simulated multi-touch action based, at least in part, on the reference point and on the further touch input; and
exiting from the simulated multi-touch state to the single-touch state.

Abstract
Disclosed is a single-touch screen interface that supports two operational states. First is a traditional single-touch state. Second is a “simulated multi-touch state” which allows the user to interact with the single-touch screen in much the same way as he would interact with a multi-touch screen. The user, while in the single-touch state, selects the simulated multi-touch state by performing a special “triggering” action, such as clicking or double clicking on the display screen. The location of the triggering input defines a “reference point” for the simulated multi-touch state. While in the simulated multi-touch state, this reference point is remembered, and it is combined with further touch input to control a simulated multi-touch operation. When the simulated multi-touch operation is complete, the interface returns to the single-touch state. In some embodiments, the user can also leave the simulated multi-touch state without completing a simulated multi-touch operation.

14. A personal communication device comprising:
-
a single-touch display screen; and a processor operatively connected to the single-touch display screen and configured for beginning in a single-touch state, for entering a simulated multi-touch state, wherein entering the simulated multi-touch state is triggered by receiving touch input from the single-touch screen, the triggering touch input defining a reference point on the single-touch screen, for, while in the simulated multi-touch state, receiving further touch input from the single-touch screen, for performing a simulated multi-touch action based, at least in part, on the reference point and on the further touch input, and for exiting from the simulated multi-touch state to the single-touch state. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
