Abstract
A method comprising obtaining a first location of a first pointer contact on an input surface; calculating a restricted area proximate the first location; processing the first pointer contact; and inhibit processing of a second location of a second pointer contact within the restricted area.
Claims20
A method comprising:
- obtaining a first location of a first pointer contact on an input surface, wherein the first pointer contact is created by a first pointer;
- calculating a restricted area proximate and surrounding the first location;
- processing the first pointer contact;
- inhibiting processing of a second location of a second pointer contact within the restricted area, wherein the second pointer contact is from a second pointer different from the first pointer that created the first pointer contact on the input surface;
- and after receiving an instruction specified by a user to remove the restricted area via an icon displayed on the input surface, removing the restricted area accordingly.

A non-transitory computer-readable medium having stored thereon instructions which when executed by a processor cause the processor to:
- obtain a first location of a first pointer contact on an input surface, wherein the first pointer contact is created by a first pointer;
- calculate a restricted area proximate the first location;
- process the first pointer contact;
- inhibit processing of a second location of a second pointer contact within the restricted area,
- wherein the second pointer contact is from a second pointer different from the first pointer that created the first pointer contact on the input surface;
- and
- after receiving an instruction specified by a user to remove the restricted area via an icon displayed on the input surface, remove the restricted area accordingly.
4 more elements
An interactive input system comprising:
- an input device configured to determine locations of pointer contacts thereon;
- memory storing instructions;
- and a processor configured to execute the instructions to:
- obtain a first location of a first pointer contact on an input surface, wherein the first pointer contact is created by a first pointer;
- calculate a restricted area proximate the first location;
- process the first pointer contact;
- inhibit processing of a second location of a second pointer contact within the restricted area wherein the second pointer contact is from a second pointer different from the first pointer that created the first pointer contact on the input surface;
- and after receiving an instruction specified by a user to remove the restricted area via an icon displayed on the input surface, remove the restricted area accordingly.
