As vibrotactile feedback systems become increasingly commonplace, their application scenarios are becoming more complex. 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.

Syntacts：音频控制触觉的开源软件和硬件

随着振动触觉反馈系统变得越来越普遍，其应用场景也变得越来越复杂。我们提出了一种满足新兴设计要求的振动器控制方法，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。我们描述了一种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障碍。我们还提供了一个关于常见控制方案的教程，并讨论了它们的优点和缺点。我们的软件专门用于以极低的延迟控制振动器阵列。此外，Syntacts 还包括合成和排序线索，并在触觉阵列上将它们空间化的方法。Syntacts Amplifier 与音频硬件集成，为 tactor 提供高质量的模拟信号，而不会给系统增加过多的噪音。最后，我们展示了使用 Syntacts 进行的基准研究与商用系统相比的结果。
