Proximity sensor device and method with activation confirmation

A touch screen interface for an electronic device, the touch screen interface comprising:

• a display screen configured to display a plurality of icons, each icon identifying a location on the touch screen interface corresponding to a function on the electronic device;
• a capacitive sensor proximate to the display screen, the capacitive sensor adapted to sense object presence in a sensing region, wherein the sensing region overlaps at least part of the display screen;
• and
• a processor, the processor coupled to the sensor, the processor configured to:
• responsive to an identified presence of a first object in the sensing region, identify a selected function that corresponds to an icon in the plurality of icons that is proximate a location of the first object in the sensing region;
• and
• responsive to an identified presence of a second object in the sensing region beginning both after the identified presence of the first object begins, and before the identified presence of the first object ends, confirm the selected function regardless of a location of the identified presence of the second object in sensing region.

A method for indicating a function on a touch screen, the method comprising:

• monitoring electrical signals with a processor for indicia of object presence in a sensing region provided by the touch screen;
• responsive to an identified presence of a first object in the sensing region, identify a selected function that corresponds to a location of the first object in the sensing region;
• and
• responsive to an identified presence of a second object in the sensing region within a specified temporal period that overlaps with the identified presence of the first object in the sensing region, confirm the selected function.

A program product comprising:

• a) a sensor program, the sensor program adapted to;
• responsive to an identified presence of a first object in a sensing region of a touch screen, identify a selected function that corresponds to a location of the first object in the sensing region;
• responsive to an identified presence of a second object in the sensing region within a specified temporal period that overlaps with the identified presence of the first object in the sensing region, confirm the selected function;
• and
• b) non-transitory computer-readable media bearing said sensor program.

A touch screen interface for an electronic device, the touch screen interface comprising:

• a display screen;
• a sensor proximate to the display screen, the sensor adapted to sense object presence in a sensing region, wherein the sensing region overlaps at least part of the display screen;
• and
• a processor, the processor coupled to the sensor, the processor configured to:
• responsive to an identified presence of a first object in the sensing region simultaneously occurring with an identified presence of a second object in the sensing region, and after a beginning of a motion of either the first or the second object, identify a selected function that corresponds to a location of one of the first and second objects;
• responsive to the motion of the either the first or the second object, indicate an adjustment relating the selected function.
