Abstract
Apparatuses and methods of touch discrimination are described. One method receives data from an occupant classification system and sets a touch detection threshold of a touch-sensing device based on the received data. The method may be used to discriminate between an adult touch and a child touch and to selectively allow access to control functionality to adults and not to children.
Claims21
A method comprising:
- setting a capacitive touch detection threshold of an input touch-sensing device based on input from a seat occupant classification system;
- detecting a touch at a location of a capacitive sense element of a plurality of capacitive sense elements comprised by the input touch-sensing device of a vehicle user interface;
- classifying, by a processing device and based on a plurality of factors, whether the touch is a child touch or an adult touch, wherein the plurality of factors comprises comparing an amount of capacitance induced by the touch at the location of the capacitive sense element of the input touch-sensing device to the capacitive touch detection threshold;
- and
- selectively enabling or disabling at least a portion of control functionality of the vehicle user interface based on the classification.
2 more elements
A system comprising:
- an input touch-sensing device;
- and
- a processing device coupled to the input touch-sensing device, wherein the processing device is to:
- set a capacitive touch detection threshold of an input touch-sensing device based on input from a seat occupant classification system;
- detect a touch at a location of a capacitive sense element of a plurality of capacitive sense elements comprised by the input touch-sensing device;
- classify, based on a plurality of factors, whether the touch is a child touch or an adult touch, wherein the plurality of factors comprises comparing an amount of capacitance induced by the touch at the location of the capacitive sense element of the input touch-sensing device to the capacitive touch detection threshold;
- and
- selectively enable or disable at least a portion of control functionality associated with the input touch-sensing device based on the classification.
5 more elements
A method comprising:
- receiving data from a seat occupant classification system to classify a seat occupant as a child or an adult;
- and
- setting a capacitive touch detection threshold of an input touch-sensing device based on the received data, wherein the input touch-sensing device is to detect a touch by comparing an amount of capacitance induced by the touch at a location of a capacitive sense element of a plurality of capacitive sense elements comprised by the input touch-sensing device to the capacitive touch detection threshold.
