以高頻壓縮空氣渲染觸覺感知

Abstract

我們提出 AirVibe，探索並研究高頻（0 到 160 赫茲）壓縮空氣和空氣流速如何影響觸覺感知。我們首先進行了感知研究，以了解高頻空氣的質性體驗，然後進行幅度估計使用者研究，以研究空氣頻率和空氣流速如何影響使用者最常提到的觸覺感知：彈性、流動性、毛羽性、粗糙度和起伏性。結果表明，較高的空氣頻率導致感知較高的流動性和較低的彈性、起伏性和粗糙度；而較高的空氣流速導致感知較高的毛羽性和較低的彈性、流動性、起伏性和粗糙度。此外，空氣頻率對這五種觸覺感知幅度的影響為 1.4 倍到 5.1 倍，空氣頻率和空氣流速相結合可以進一步將幅度動態範圍擴大到 3.1 倍到 13.3 倍。

We present AirVibe, which explores and models how high-frequency compressed air (0 - 160 Hz) and air speed affect perceived tactile sensations. We first conducted a perception study to understand the qualitative experience of high-frequency air, followed by a magnitude estimation study to model how air frequency and air speed affect the most frequently mentioned tactile perceptions: elasticity, fluidity, hairiness, roughness, and bumpiness. Results show that higher air frequency leads to higher perceived fluidity and lower elasticity, bumpiness, and roughness; whereas higher air speed leads to higher perceived hairiness but lower elasticity, fluidity, bumpiness, and roughness. Furthermore, air frequency affects the perceived magnitude of these five tactile sensations by a factor of 1.4x - 5.1x, and air frequency and air speed combined can further expand the dynamic range to 3.1x - 13.3x.
