4.2.7 Generic Sensor
The Generic sensor provides a comprehensive means by which platform driver support can be extended
dynamically without changes to the platform driver. The Generic sensor achieves this by directly exposing
the sensor category, type and supported events, properties and datafields by means of GUIDs and
PROPERTYKEYs, which can consumed directly by the Operating System’s sensor driver without having
to parse and translate HID Usages.
A Generic sensor is different from a Custom sensor in that, where the Custom sensor presents itself at the
platform level as a Custom sensor with certain properties, the Generic sensor presents itself as the Category
and Type of sensor defined in the Category and Type fields. A further distinction is that, where the Custom
sensor must encapsulate datafields in one of the defined Custom datafields, the Generic sensor can
represent any supported event, property or datafield defined in the Event, Property and Datafield fields.
Use of a Generic sensor may be desireable in several circumstances:
1) The vendor may wish create a new category or type of sensor not previously anticipated by the
platform driver;
