Gesture language for a device with multiple touch surfaces

A method comprising:

• executing a first mode of touch-input interpretation that interprets touch input received on the first touch-sensitive display associated with a computing device;
• receiving a first touch input via the first touch-sensitive display and a second touch-sensitive display associated with the computing device, wherein the first touch input comprises a gesture having a first touch point on the first touch-sensitive display and a second touch point on the second touch-sensitive display, and wherein the gesture is selected from a group that comprises:
• a pinch gesture, a swipe gesture, and a multi-finger tap gesture;
• determining that the gesture is a gesture modifier configured to change the first touch-sensitive display from the first mode of touch input-interpretation to a second mode of touch input-interpretation that interprets a subsequent touch input, receivable via the first touch-sensitive display, differently than the first mode of touch-input interpretation;
• and
• toggling the first touch-sensitive display from the first mode of touch input-interpretation to the second mode of touch input-interpretation based on a determination that the gesture is the gesture modifier, wherein the toggling configures the first touch-sensitive display so that receipt of the subsequent touch input is interpreted differently from an interpretation provided through the first mode.

A system comprising:

• a first touch-sensitive display;
• a second touch-sensitive display;
• at least one processor that is connected with the first touch-sensitive display and the second touch-sensitive display;
• at least one computer-readable storage media storing instructions that are executable by the at least one processor to implement an input module configured to:
• execute a first mode of touch-input interpretation that interprets touch input received on the first touch-sensitive display associated with a computing device;
• receive a first touch input via the first touch-sensitive display and a second touch-sensitive display associated with the computing device, wherein the first touch input comprises a gesture having a first touch point on the first touch-sensitive display and a second touch point on the second touch-sensitive display, and wherein the gesture is selected from a group that comprises:
• a pinch gesture, a swipe gesture, and a multi-finger tap gesture;
• determine that the gesture is a gesture modifier configured to change the first touch-sensitive display from the first mode of touch input-interpretation to a second mode of touch input-interpretation that interprets a subsequent touch input, receivable via the first touch-sensitive display, differently than the first mode of touch-input interpretation;
• and
• toggle the first touch-sensitive display from the first mode of touch input-interpretation to the second mode of touch input-interpretation based on a determination that the gesture is the gesture modifier and the subsequent touch input is interpreted differently from an interpretation provided through the first mode.
