摘　　要：头部跟踪器是虚拟现实系统中关键传感设备之一,它的任务是检测头部位置与方位。本文介绍了一种新型的基于三轴加速度计的惯性头部跟踪器的设计,给出并分析了部分性能指标的测试结果,对该头部跟踪器的应用进行了初步尝试,结果表明该惯性头部跟踪器可实际应用于头部缓慢转动场合下仅指示偏转和俯仰两个自由度的虚拟现实系统中。Head position tracker is one of the most important sensor equipments in the virtual reality system. Its main purpose is to detect the position and orientation of the head. In this paper, a new design of head position tracker based on tri-axis accelerometer is introduced. Some performance indexes are tested and analyzed; besides, the preparatory application of it has been tried. The result proves that this head position tracker can be applied in the virtual reality system under the condition Of tiny orientation （only indi- cating pitch and roll） change.
