Abstract
A system for calibrating alignment of two or more sensors in a virtual reality (VR) or augmented reality (AR) display device, the two or more sensors in the display device including at least one magnetic sensor. The system can include a first pair of conductive loops oriented in parallel planes and spaced apart along a first axis. The system can also include a mount configured to attach to the display device and to support the display device in a first predetermined spatial relationship with respect to the first pair of conductive loops.
