精确的设备运动跟踪支持许多应用，如虚拟现实（VR）和增强现实（AR）。为了使这些应用在人们的日常生活中，低成本的基于声学的运动跟踪方法被提出。然而，现有的基于声学的方法都是基于距离估计的。这些方法测量扬声器和麦克风之间的距离。通过扬声器或麦克风阵列，它可以获得多个估计距离，并进一步实现多维运动跟踪。基于距离的运动跟踪方法的缺点是它们需要大的阵列尺寸来获得准确的结果。有些系统甚至需要大于1米的阵列。这一弱点限制了现有解决方案在智能扬声器等单个设备中的采用。为了解决这个问题，我们提出了基于声强的角度跟踪（ASAT）系统，并进一步实现了基于ASAT的运动跟踪系统。反卫星武器通过建立一个周期性变化的声场来实现角度跟踪。带有麦克风的设备将感测声场中周期性变化的声音强度。当设备移动时，接收到的声音强度的周期将改变。从而推导出角度变化量，实现角度跟踪.当扬声器和麦克风之间的距离在3 m范围内时，基于ASAT的系统可以获得5 cm的定位精度。
Accurate device motion tracking enables many applications like Virtual Reality (VR) and Augmented Reality (AR). To make these applications available in people's daily life, low-cost acoustic-based motion tracking methods are proposed. However, existing acoustic-based methods are all based on distance estimation. These methods measure the distance between a speaker and a microphone. With a speaker or microphone array, it can get multiple estimated distances and further achieve multidimensional motion tracking. The weakness of distance-based motion tracking methods is that they need large array size to get accurate results. Some systems even require an array larger than 1 m. This weakness limits the adoption of existing solutions in a single device like a smart speaker. To solve this problem, we propose Acoustic Strength-based Angle Tracking (ASAT) System and further implement a motion tracking system based on ASAT. ASAT achieves angle tracking by creating a periodically changing sound field. A device with a microphone will sense the periodically changing sound strength in the sound field. When the device moves, the period of received sound strength will change. Thus we can derive the angle change and achieve angle tracking. The ASAT-based system can obtain the localization accuracy as 5 cm when the distance between the speaker and the microphone is in the range of 3 m.
