Remarks
Capabilities
The motion sensor has the following minimal set of capabilities:
Supports detection of a person present at the POS device.
Supports reporting of motion-detection changes, either by hardware or software detection.
Model
The motion sensor defines two motion sensor indications as constants. It is assumed that the motion sensor supports present and absent indications. The constants for these motion sensor are:
StatusMotionPresent
StatusMotionAbsent
StatusUpdateEvent events are fired using the above values. The timeout value is used to set the number of milliseconds between the last time someone was present and a StatusMotionAbsent StatusUpdateEvent being fired.
Device Sharing
The motion sensor is a sharable device. Its device sharing rules are:
After opening and enabling the device, the application can access all properties and methods and receive StatusUpdateEvent events.
If more than one application has opened and enabled the device, each of these applications can access its properties and methods. StatusUpdateEvent events are fired to all of these applications.
The motion sensor cannot be claimed for exclusive access. Therefore, if an application calls claim or release, these methods raise an exception.
