Abstract

A system, method, and apparatus for managing the drawing of graphical objects are disclosed. An example apparatus includes an interface configured to receive at least one gesture from a user in relation to a client device. The apparatus also includes a coordinate detector configured to determine a coordinate-plane for the at least one gesture and determine coordinates of points along the at least one gesture. The apparatus further includes an object detector configured to determine a graphical object based on the coordinates of points corresponding to the at least one gesture and an object manager configured to cause the graphical object to be displayed by the client device. The graphical object includes a formalized editable version of the at least one gesture in a format native to an application selected to receive the graphical object.

Claims

1. An apparatus comprising:

an interface configured to detect at least one gesture from a user in relation to a client device;

a coordinate detector configured to;

determine a rectangular-shaped coordinate-plane with dimensions substantially equal to a width and a height of the gesture,

determine at least four moat regions along a perimeter of the coordinate-plane, and

determine coordinates of points along the gesture;

an object detector configured to;

determine whether a threshold number of the coordinates are within each of the moat regions, the threshold number related to at least 25% of a length of the respective moat region,

designate each moat region as a detected moat region responsive to determining that the threshold number of coordinates is reached for the respective moat region, and determine a first set of graphical object types that are specified to correspond the number of detected moat regions, and

determine a second set of graphical object types that are specified to include at least the number of detected moat regions in addition to at least one undetected moat region; and

an object manager configured to cause the first set of graphical object types and the second set of graphical object types to be displayed by the client device for selection by the user into a formalized editable version of the graphical object type.
