We describe the design and evaluation of PIV, a personalizable and inconspicuous vibrotactile breathing pacer. Given the prevalence and adverse impact of anxiety and anxiety disorders, our goal is to develop a technology that helps people regulate their anxiety through paced breathing. We examined two previously unstudied questions: What is an effective vibrotactile pattern for paced breathing, and where should the tactors be placed on the body to make the pacer most effective? We designed a series of personalized vibrotactile pacing patterns, and evaluated them on three body sites, in terms of self-reported and psychophysiological measures including skin conductance and breath wave parameters. The results show that personalization plays an important role in PIV’s pattern and placement design choices. We concluded that the choice of frequency based, strong-exhale-phased patterns and abdomen placement are appropriate for future studies.

PIV

我们描述了 PIV 的设计和评估，这是一种个性化且不显眼的振动触觉呼吸起搏器。鉴于焦虑症和焦虑症的普遍性和不利影响，我们的目标是开发一种技术，帮助人们通过有节奏的呼吸来调节他们的焦虑。我们研究了两个以前未研究过的问题：什么是有效的有节奏呼吸的振动触觉模式，以及应该将触感器放在身体的哪个位置以使起搏器最有效？我们设计了一系列个性化的振动触觉起搏模式，并根据自我报告和心理生理测量（包括皮肤电导和呼吸波参数）在三个身体部位对它们进行了评估。结果表明，个性化在 PIV 的图案和布局设计选择中起着重要作用。
