Today's technology includes only minimal touch feedback, which has unfortunate consequences on people's lives. Touchscreen phones and car dashboards demand visual attention, putting people's safety at risk. Virtual environments neglect or diminish users' abilities to grasp and move objects, impacting dexterity. The emerging immersive education and work training opportunities largely exclude blind and low-vision users. Finally, the fact that telecommunication (for example, calling family to check in) lacks social touch and a sense of co-presence leads to anxiety and depression over time. Advances in programmable touch technology, known as haptic technology, can offer a future free of these challenges, but experienced haptic designers are few, and becoming an expert in haptics takes years of practice. The main question in haptic design remains: "How can I convey the desired meaning to users through touch?" It is surprisingly difficult to design vibration signals that can evoke relevant meanings in users' minds and are easy to distinguish from one another. Currently, creating such signals relies on trial-and-error exploration of engineering parameters and extensive user testing. This inefficient process discourages domain-expert designers (car manufacturers, accessibility experts, educators, therapists, and the like) from including haptics in their applications. To address this barrier to using haptics, this project will democratize vibration design by investigating how humans interpret and distinguish vibration signals. Specifically, the project will develop models that predict how people (1) describe a signal's meaning with natural language and (2) perceive the similarity of signals. Next, the investigator and her team will (3) build haptic authoring tools that interleave these models with designer input to help quickly converge on plausible haptic signals for an application. The investigator team will then study the tools' impact on enabling designers to achieve their creative visions. This project will focus on three vibrotactile technologies that target receptors in our hands and offer the widest range of contact and contactless vibrotactile feedback: mechanical vibration actuators, surface electrovibration devices, and mid-air ultrasound haptics. In contrast to previous studies that rely on signals with a few controlled parameters, this research will model the human processing of complex signals created by human designers. The outcomes of this research will pioneer the development of a new class of sensory language models, reveal generalizable trends in human vibrotactile perception and language across three technologies, and identify specific opportunities for haptic tools and residency programs to scaffold learning and collaboration for interdisciplinary haptic design teams.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

当今的技术仅包括最小的接触反馈，这对人们的生活产生了不幸的后果。触摸屏电话和汽车仪表板需要视觉关注，使人们的安全处于危险之中。虚拟环境忽略或降低用户掌握和移动对象的能力，从而影响灵活性。新兴的身临其境的教育和工作培训机会在很大程度上排除了盲人和低视野。最后，电信（例如，呼吁家人入住）的事实缺乏社交感和共同主持的感觉，会导致随着时间的流逝焦虑和抑郁。可编程触摸技术的进步（称为触觉技术）可以免费提供这些挑战，但是经验丰富的触觉设计师很少，并且成为触觉的专家需要多年的实践。触觉设计的主要问题仍然存在：“如何通过触摸将所需的含义传达给用户？”令人惊讶的是，设计可能在用户思想中引起相关含义并且很容易区分的振动信号非常困难。当前，创建此类信号依赖于对工程参数和广泛用户测试的反复试验探索。这种低效的过程阻止了域特殊设计师（汽车制造商，可访问性专家，教育工作者，治疗师等），将其包括在其应用中。为了解决使用触觉的障碍，该项目将通过调查人类如何解释和区分振动信号来使振动设计民主化。具体而言，该项目将开发模型，以预测人们（1）如何用自然语言描述信号的含义，以及（2）感知信号的相似性。接下来，调查员和她的团队将（3）构建触觉创作工具，这些工具将这些模型与设计师的输入交织在一起，以帮助快速收敛于应用程序的合理触觉信号。然后，调查员团队将研究工具对使设计师能够实现创造性愿景的影响。该项目将集中在三种触发我们手中的受体，并提供最广泛的接触率和无接触式颤振反馈的范围：机械振动执行器，表面电动启动设备以及中间空气超声触觉。与以前依赖具有一些受控参数的信号的研究相反，该研究将模拟人类设计师创建的复杂信号的人类处理。 The outcomes of this research will pioneer the development of a new class of sensory language models, reveal generalizable trends in human vibrotactile perception and language across three technologies, and identify specific opportunities for haptic tools and residency programs to scaffold learning and collaboration for interdisciplinary haptic design teams.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader影响审查标准。
