SwayForce：透過增加手持控制器的搖晃幅度增強方向力回饋感知

Abstract

螺旋槳及高壓氣流等現有的力回饋技術囿於設備的限制，難以提供 真實強度的感受。本論文介紹一種名為 SwayForce 的增加力回饋強度 感知方法。此方法無需額外增加力回饋裝置的組件，只需在目標的力 回饋後引入相反方向的反彈力回饋，達成增加一維度力回饋手持控制 器的旋轉，而增強使用者感受的強度。本文首先對反彈力回饋對於控 制器旋轉的影響進行量化分析，然後進行了一項六位參與者參與的形 成性研究，以確定虛擬實境第一人稱射擊遊戲中的力回饋設計。最後， 通過對 18 位參與者進行的使用者體驗研究來評估該力回饋感知增強方 法。研究結果顯示，SwayForce 能夠增加力回饋強度的感知，並提高 遊戲過程中的整體娛樂性。

Existing force feedback technologies, such as propellers and compressed air jets, have limitations in providing realistic levels of intensity. This pa- per presents SwayForce, an innovative approach to increase perceived force feedback magnitude without requiring additional hardware or energy con- sumption. The proposed technique incorporates a rebound force after the target force feedback to amplify the rotation of 1-DoF force feedback hand- held controllers. We first quantified the effect of rebound forces on controller rotation and further conducted a formative study involving 6 participants to determine the preferred force feedback design in a VR first-person shooter game. Subsequently, an evaluation was carried out with 18 participants to assess user experience; results indicate that SwayForce increased perceived magnitude and enhanced overall entertainment during gameplay.
