虛擬表皮壓感的可視化研究

虛擬表皮壓感的可視化研究摘要：

虛擬現(xiàn)實(VR)技術的普及與應用，為人機交互帶來了新的可能性。其中，虛擬表皮壓感的實現(xiàn)成為了一個熱點研究方向。目前，通過力反饋手套等設備實現(xiàn)該功能的研究較多，但這些方法存在成本高、應用范圍狹窄等問題。本文提出一種基于視覺化的虛擬表皮壓感方法，通過控制材質、顏色等視覺因素，模擬出真實的觸覺感受。

首先，我們對生理學和感知心理學等方面的研究進行了綜述，分析了不同外在因素對人體皮膚觸覺反應的影響。然后，根據(jù)不同觸覺感受的特點，提出了不同的視覺化方案。最后，我們設計了一款表皮觸覺可視化實驗系統(tǒng)，并測試了不同條件下的視覺化效果以及與真實觸覺感受的對比。

實驗結果表明，我們提出的虛擬表皮壓感方式具有較好的可行性和可視化效果。通過對比實驗，我們發(fā)現(xiàn)該方法在模擬輕柔、刺激性的觸覺感受方面表現(xiàn)較好。雖然該方法還有待進一步完善，但其可視化的優(yōu)點和較低的成本，預示著它有廣闊的應用前景。
