可穿戴触觉系统为人类用户提供便携式、私人的触觉通信。迄今为止，可穿戴触觉设备的进步通常集中在使用单一模态的触觉提示传输的优化上，或者已经组合了两种类型的皮肤反馈，每种反馈映射到任务的特定参数。或者，研究人员已经采用触觉致动器阵列来最大化用户的信息吞吐量。然而，当要传输大的提示集时，例如传输语言所需的那些提示集，所传输的提示之间的感知干扰可能会降低单感官系统的功效，或者需要大的足迹来确保向用户呈现显著的时空提示。在本文中，我们提出了一个可穿戴，多感官触觉反馈系统，MISSIVE（拉伸，挤压和集成振动元件的多感官界面），将多感官触觉线索传达给用户的上臂。我们提出的实验结果表明，渲染触觉线索与多感官组件，特别是横向皮肤拉伸，径向挤压，和振动触觉刺激-与具有所有振动触觉组件的类似线索相比，改善了感知的可重复性。这些结果支持将不同的刺激，振动触觉和nonvibrotacular，应用程序需要大的触觉提示集。
Wearable haptic systems offer portable, private tactile communication to a human user. To date, advances in wearable haptic devices have typically focused on the optimization of haptic cue transmission using a single modality, or have combined two types of cutaneous feedbacks, each mapped to a particular parameter of the task. Alternatively, researchers have employed arrays of haptic tactile actuators to maximize information throughput to a user. However, when large cue sets are to be transmitted, such as those required to communicate language, perceptual interference between transmitted cues can decrease the efficacy of single-sensory systems, or require large footprints to ensure salient spatiotemporal cues are rendered to the user. In this paper, we present a wearable, multi-sensory haptic feedback system, MISSIVE (Multi-sensory Interface of Stretch, Squeeze, and Integrated Vibration Elements), that conveys multi-sensory haptic cues to the user's upper arm. We present experimental results that demonstrate that rendering haptic cues with multi-sensory components-specifically, lateral skin stretch, radial squeeze, and vibrotactile stimuli-improved perceptual distinguishability in comparison to similar cues with all-vibrotactile components. These results support the incorporation of diverse stimuli, both vibrotactile and nonvibrotactile, for applications requiring large haptic cue sets.
