 Acoustic tracking can be influenced by surrounding noise causing inaccurate measurements. It also demands careful calibration and does not provide high update rates. Even with its faults, acoustic tracking can be used injunction with other methods to improve positional tracking.
 ===Inertial===
-Inertial tracking determines the linear acceleration of the object. In most [[HMD]]s and smartphones, inertial tracking is performed by [[accelerometer]]s and [[gyroscope]]s.
+Inertial tracking is performed by [[accelerometer]] and [[gyroscope]]. Accelerometer measures the linear acceleration while gyroscope measures the angular velocity.
+While accelerometer and gyroscope supply low latency and high update rate. They do not provide positional information accurately.
