Partial detect mode
First Claim
1. A touch sensitive system comprising:
- a touch sensitive panel defining a touch surface;
a plurality of emitters configured to emit light across the touch surface;
a plurality of detectors configured to detect the light;
a plurality of distributed control devices, wherein each of the plurality of distributed control devices is configured to control operation of a respective segment of the plurality of emitters and the plurality of detectors;
a main control unit connected with the plurality of distributed control devices;
wherein during a partial detect mode, a first subset of said plurality of distributed control devices are activated and wherein the first distributed control device in the first subset is configured to control a first set of emitters to emit light across a partial area of said touch surface; and
wherein the first distributed control device is further configured to;
detect a predetermined gesture on the partial area of said touch surface; and
generate a gesture signal indicating the predetermined gesture,wherein a remaining set of distributed control devices which were not active in the partial detect mode are configured to be activated in response to receiving the gesture signal.

Abstract
The disclosure relates to a touch sensitive system comprising a touch sensitive panel defining a touch surface, a plurality of emitters configured to emit light into the panel for propagation in the panel, a plurality of detectors configured to detect the light propagating in the panel, a plurality of distributed control devices each configured to control operation of a segment of emitters and detectors, a main control unit configured to control the distributed control devices. The touch sensitive system is configured to be set in a partial detect mode in which mode a first of the distributed control devices is configured to be active and to control a first emitter to emit light in a partial region of the panel coincident with a partial area of the touch surface. The touch sensitive system is further configured to detect a predetermined gesture on the partial area of the touch surface, generate a gesture signal indicating the predetermined gesture, and activate a feature of the touch sensitive system in accordance with the predetermined gesture. The disclosure also relates to a method in connection with the touch sensitive system.

19. A method for activating a feature of a touch sensitive system comprising a plurality of distributed control devices connected with a main control unit, the method comprising:
-
emitting light from a plurality of emitters across a touch surface; detecting the emitted light at a plurality of detectors; controlling, with the plurality of distributed control devices, operation of the plurality of emitters and the plurality of detectors; activating a first subset of the plurality of distributed control devices in a partial detect mode; detecting, with a first distributed control device, a predetermined gesture on a partial area of said touch surface; and generating, with the first distributed control device in the first subset, a gesture signal indicating the predetermined gesture; wherein a remaining set of distributed control devices which were not active in the partial detect mode are activated in response to receiving the gesture signal.
