Definition and use of node-based points, lines and routes on touch screen devices

Abstract

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.

Benefits of technology

[0021]Being node-based, once defined the points, lines, routes and corridors can be easily manipulated and edited, and the lines, routes and corridors can be efficiently stretched and re-sized. In some embodiments the use of key nodes permits operations on a composite entity made up of multiple line or route segments, such as the mo

Problems solved by technology

However, with the exception of shape, area and window definition by the current author in U.S. Pat. No. 0,862,382 (Stone, 2013), no methods are node-based.

However there is no means to define multiple new geographic points, lines or routes using touches against a point on a map on a touch screen, and then to share these with selected users or use them in a mapping application such as navigation or real estate management.

The lack of a node based approach may be suitable for certain drawing applications, but presents difficulties for complex editing, conversion to other graphical entities, sharing with remote users and databases and joining of line segments to create a multi-segment line.

Currently therefore there is no method available for line definition on multi-touch enabled devices which supports complex editing, remote sharing or the explicit joining
