DEFINITION AND USE OF NODE-BASED POINTS, LINES AND ROUTES 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 points of definition, lines, routes and corridors from these nodes. Where the device has a communications capability, the locally defined points of definition, routes and corridors can be shared with remote users and databases, and similar entities created by remote users can be viewed on a local display. The method and system are of particular benefit to navigation applications, map customization on touch screen devices, real estate management, scientific measurement, and geographic information systems.

1. A method for interpreting user touches on a touch screen device to create and edit points of definition, lines, routes and corridors on the display of said touch screen device, comprising:
a. recognizing single and double, concurrent user touches to touch screen device, b. interpreting said user touches as node positions, node touch sequences and associated node motions on the screen display of said touch screen, c. interpreting said node positions, said node touch sequences and said node motions to determine the point, line segment or route segment entities to be drawn on the touch screen display, d. retaining recognition and information of said entities persistently after said user touches to the touch screen device have ceased, e. allowing reselection by a user of a previously defined entity for operation on that entity. f. allowing reselection by a user of any node of a previously defined entity for operation on that node.
