1. A user interaction system comprising:
a totem having:
a totem body; and
a totem inertial measurement unit (IMU) located on the totem body, to generate a totem IMU signal due to movement of the totem;
a head unit;
a processor;
a storage device connected to the processor;
a set of instructions on the storage device and executable by the processor, including:
a world frame;
an executable routine connected to the totem IMU to generate a first location of the totem in the world frame based on the totem IMU data;
a location determination modeler that determines a second location of the totem relative to the world frame; and
a location correction routine connected to the first location and the second location to reset sensors of the totem IMU to match the second location;
a data source to carry image data; and
a display system connected to the data source to display a virtual object using the image data to a user, a location of the virtual object being based on the first location of the totem.
