概要
- The Collection Physical usage type identifies a usage applied to a physical collection, usually a collection of axes.
- A physical collection is used for a set of data items that represent data points collected at one geometric point.
- This is useful for sensing devices that may need to associate sets of measured or sensed data with a single point.
- It does not indicate that a set of data values comes from one device, such as a keyboard. In the case of a device that reports the position of multiple sensors,
- physical collections are used to show which data comes from which sensor.
