35 <strong>HID</strong> <strong>Sensor</strong> <strong>Usage</strong>s<br />
Country or Region SV – Indicates country or region represented as an ISO 3166 1alpha-2<br />
country/region code.<br />
Postal Code SV – Indicates the postal code.<br />
1.11 Mechanical <strong>Sensor</strong> Field <strong>Usage</strong>s<br />
These fields are commonly supported by mechanical sensors.<br />
Boolean Switch State SF – Reports the on/off state of a Boolean switch.<br />
Boolean Switch Array<br />
State<br />
SV – Reports the on/off state of each of an array of Boolean<br />
switches.<br />
Multivalue Switch Value SV – Reports the multivalue state of a Multivalue switch.<br />
Force SV – Measures force. Default unit of measure is Newtons; can be<br />
overridden using explicit Unit and/or Unit Exponent.<br />
Absolute Pressure SV – Measures absolute pressure. Default unit of measure is<br />
Pascals; can be overridden using explicit Unit and/or Unit<br />
Exponent.<br />
Gauge Pressure SV – Measures relative gauge pressure. Default unit of measure is<br />
Pascals; can be overridden using explicit Unit and/or Unit<br />
Exponent.<br />
Strain SV – Measures strain (in percent). Can be scaled with a Unit<br />
Exponent.<br />
Weight SV – Measures weight. Default unit of measure is kilograms; can<br />
be overridden using explicit Unit and/or Unit Exponent.<br />
Vibration State DF – The on/off state of a Haptic feedback vibrator.<br />
Forward Vibration Speed DV – The forward speed of the vibrator (in percent). Can be<br />
scaled with a Unit Exponent.<br />
Backward Vibration<br />
Speed<br />
1.12 Motion <strong>Sensor</strong> Field <strong>Usage</strong>s<br />
These fields are commonly supported by motion sensors.<br />
DV – The backward speed of the vibrator (in percent). Can be<br />
scaled with a Unit Exponent. Some haptic motors do not support<br />
both forward and backward motion. For those that do, setting both<br />
forward and backward speeds to non-zero values simultaneously<br />
has a vendor-defined behavior.<br />
Motion State SF – A flag indicating presence or absence of motion.<br />
Motion Intensity SV – A positive number indicating intensity of motion if motion is<br />
detected (in percent), otherwise 0. Can be scaled with a Unit<br />
Exponent.<br />
Acceleration SV – Linear acceleration magnitude without respect to which axis<br />
it occurs in. This is usually used as a composite value for<br />
specifying min, max and accuracy for related accelerations.<br />
Default unit of measure is G’s; can be overridden using explicit
