Sensor API Glossary
- ambient light sensor
A sensor that detects the current lighting level.
- geodetic reference system
The combination of an ellipsoid, which specifies the size and shape of the earth, and a base point from which the latitude and longitude of all other points are referenced.
- light-aware user interface (UI)
A program that uses ambient light sensor data to optimize its user interface and content for particular lighting conditions.
- logical ID
A globally unique identifier (GUID) that identifies a particular logical sensor. A logical ID is required each time you connect to a logical sensor.
- logical sensor
A sensor that provides data without using a hardware device. For example, a logical sensor could provide data about the user's current location by using a service that looks up an IP address in a table.
- lux value
The amount of light, in lumens per square meter, that illuminates a surface. Ambient light sensors provide data in lux values.
- reference ellipsoid
An ellipsoid associated with a geodetic reference system, whose surface approximates the size and shape of the earth.
Hardware or software that can detect external events or environmental conditions. For example, a global positioning system (GPS) receiver is a sensor that can determine a user's current physical location.
- sensor category
A broad class of sensor devices. For example, a sensor in a video game controller that detects the position and movement of a player's hand belongs to the Orientation category of sensors.
- sensor collection
Multiple sensors that can be worked with as a group. For example, a sensor collection could include all available motion sensors, and a method could be called that retrieves this collection.
- sensor data report
A report that contains data field values that are generated by a sensor.
- sensor device
A hardware device that can detect external events or environmental conditions. A single hardware device can contain multiple sensors.
- sensor manager
A programming object that maintains a list of available sensors and provides access to them.
- sensor type
A specific kind of sensor, such as a three-dimensional accelerometer.
