| dc.description.abstract | 現在的虛擬現實（VR）不僅僅是以靜態的姿勢體驗虛擬環境（VE）。用戶可以在虛擬環境中自由行走，而不需要承擔現實生活中的任何不利因素。與傳統的靜態VR體驗相比，VR運動實現了各種技術，讓用戶在虛擬世界中行走，而現實世界的環境卻很有限。重定向行走算法的目的是提供無障礙和無束縛的VR體驗。然而，以前的算法忽略了用戶的 '暈眩'和接收信號的強度，這將導致體驗的質量大大降低。在這篇論文中，我們研究了一個新的優化問題，即在室內VR重定向行走系統中的路徑規劃，該問題被稱為 '帶暈眩和IRS控制的路徑規劃'，該系統具有緩解暈眩和IRS輔助的波束成形功能。 我們的目標是通過為用戶選擇最佳路徑組合和IRS相移陣列配置來實現成本函數的最小化。然後，我們提出了一種名為IRS輔助RW與暈眩減輕的算法。 此外，模擬結果表明，IRS輔助的RW與暈眩減輕算法在成本、暈眩和接收信號強度方面都能有效地超過其他比較標準。 | zh_TW |
