Systems and methods for multi-pressure interaction on touch-sensitive surfaces

A system, comprising:

• a touch-sensitive input device;
• a memory;
• a display corresponding to the touch-sensitive input device;
• and
• a processor in communication with the touch-sensitive input device, the memory, and the display, the processor configured to:
• receive a first sensor signal from the touch-sensitive input device in response to a first contact on the touch-sensitive input device, the first sensor signal comprising a first location of the first contact and a first pressure of the first contact;
• receive a second sensor signal from the touch-sensitive input device in response to a second contact on the touch-sensitive input device substantially simultaneously with the first contact, the second sensor signal comprising a second location of the second contact and a second pressure of the second contact;
• update the display based at least in part on the first pressure being different than the second pressure;
• generate a signal configured to cause a haptic effect indicating the updating of the display;
• and
• output the signal by wirelessly sending the signal to an arm strap comprising a haptic output device configured to output the haptic effect.

A non-transitory computer-readable medium comprising one or more software applications configured to be executed by a processor, the one or more software applications configured to:

• receive a first sensor signal from a touch-sensitive input device in response to a first contact on the touch-sensitive input device, the first sensor signal comprising a first location of the first contact and a first pressure of the first contact;
• receive a second sensor signal from the touch-sensitive input device in response to a second contact on the touch-sensitive input device substantially simultaneously with the first contact, the second sensor signal comprising a second location of the second contact and a second pressure of the second contact;
• update a display based at least in part on the first pressure being different than the second pressure;
• generate a signal configured to cause a haptic effect indicating the updating of the display;
• and
• output the signal by wirelessly sending the signal to an arm strap comprising a haptic output device configured to output the haptic effect.
