Recall that a Sensor is a variable length circular buffer of time stamps each with a Transform3D and the state of various buttons. In the head tracking scenario, it is the values of this Transform3D that we want to use to control our view. The reason for maintaining the information in a circular buffer is that this enables some flexibility in choosing which timestamp and data elements to use in assigning the best approximate position of whatever device is being monitored. The buffer of SensorReads ...
