US 10,241,620 B2 · Area filtering for low-latency and high-latency input event paths from a single touch sensor

Abstract

In an embodiment, a touch surface, such as a GUI is graphically divided into two or more input regions, and based on this division, input event paths from a single sensor can be integrated within an operating system to provide application developers with the ability to easily and effectively filter there-between. The graphical division allows an application developer to specify which elements of a given GUI take one path, versus another. In an embodiment, low-latency and high-latency event paths are provided; an algorithm takes into consideration input regions and, based on those regions, handles the low- and high-latency input event paths in a computer system, directing the appropriate inputs through the appropriate processing, and directing the output to the appropriate process or queue without creating constraints on the low-latency event processing due to the presence of higher-latency event paths for a given sensor.

Dependent claims

A touch sensitive device comprising:

a. computer system including a low-latency path for touch data and at least one other latency path for touch data;
b. touch sensor operatively connected to an interface of the computer system;
c. the interface of the computer system being configured to receive touch-related information from the touch sensor, and to output touch data;
and
d. configurable database identifying at least one region of the touch sensor as a low-latency input region;
e. routing process having access to the configurable database, the routing process being configured to receive the touch data from the interface, and to route touch data associated with the low-latency input region of the touch sensor to the low-latency path for touch data, and to route touch data that is not associated with the low-latency input region of the touch sensor to the at least one other latency path for touch data.
