As vibrotactile feedback systems become increasingly commonplace, their application scenarios are becoming more complex. In this article, we present a method of vibrotactor control that accommodates emerging design requirements, namely large vibrotactor arrays that are capable of displaying complex waveforms. Our approach is based on control through digital audio interfaces. We describe a new open-source software and hardware package, Syntacts, that lowers the technical barrier to rendering vibrations with audio. We also present a tutorial on common control schemes with a discussion of their advantages and shortcomings. Our software is purpose-built to control arrays of vibrotactors with extremely low latency. In addition, Syntacts includes means to synthesize and sequence cues, and spatialize them on tactile arrays. The Syntacts Amplifier integrates with the audio hardware to provide high-quality analog signals to the tactors without adding excess noise to the system. Finally, we present results from a benchmarking study with Syntacts compared to commercially available systems.
随着振动触觉反馈系统越来越普遍，它们的应用场景也变得越来越复杂。在本文中，我们提出了一种振动器控制方法，以适应新出现的设计要求，即能够显示复杂波形的大型振动器阵列。我们的方法基于通过数字音频接口进行控制。我们描述了一个新的开源软件和硬件包Syntacts，它降低了用音频渲染振动的技术门槛。我们还提供了一个关于常见控制方案的教程，并讨论了它们的优缺点。我们的软件专为以极低延迟控制振动器阵列而设计。此外，Syntacts包括合成和排序提示并在触觉阵列上对其进行空间定位的方法。Syntacts放大器与音频硬件集成，为触觉器提供高质量的模拟信号，而不会给系统增加过多噪声。最后，我们展示了与商用系统相比，使用Syntacts进行基准测试研究的结果。
