DEFINITION AND USE OF NODE-BASED SHAPES, AREAS AND WINDOWS ON TOUCH SCREEN DEVICES

摘要

A method and system are presented which will detect combinations of user touches on a touch screen device as nodes, and will create shapes, areas and windows from these nodes. Where the device has a communications capability, the locally defined shapes, areas and windows can be shared with remote users and databases, and similarly shapes, areas and windows created by others can be viewed on a local display. The method and system are of particular benefit to drawing applications, windows definition on touch screen devices, real estate management, navigation, and exploitation of mapping resources.

1. A method for interpreting multiple, concurrent user touches on a touch screen device to create a shape on the display of said touch screen device, and to interpret subsequent single user touches as selection of said shape or shape node for subsequent editing, comprising:
a. recognizing multiple, concurrent user touches to a touch screen device, b. interpreting said multiple, concurrent user touches as persistent node positions and associated node motions on the screen display of said touch screen, c. interpreting said node positions, and said node motions to determine the geometric shape to be drawn on the touch screen display, d. retaining recognition and information of said shape persistently after said concurrent user touches to the touch screen device have ceased, e. allowing reselection by a user of a previously defined shape for operation on that geometric entity, and f. allowing reselection by a user of any node of a previously defined shape for operation on that node.
