摘要: | 非接地式力回饋技術,像是噴氣推進或是螺旋槳,都可以在達到50~500毫秒以內產生4N力道的衝擊。然而,針對像是網球和打鼓這類的事件,現今的技術仍然只能產生相對於真實世界力道大小弱10~100倍,持續時間慢50~500倍的力回饋。為了解決這些限制,我們做了AirCharge,一個可以透過積聚空氣推進動量產生瞬間且具有方向性力的創新力回饋裝置。藉由安裝高壓空氣噴頭在旋轉臂上,AirCharge可以放大約20倍的衝擊力道同時達到和真實世界衝擊一樣的1毫秒的持續時間。為了支援高頻率的衝擊,我們利用反向傘齒輪箱設計出了一個雙旋轉臂結構來消除陀螺效應,並且頻率可以到達10赫茲。使用者體驗評估針對使用/不使用AirCharge的機構進行比較。實驗結果顯示,AirCharge可以有效的改善體驗真實度並且受到受測者青睞。 Ungrounded force feedback technologies, such as air jet propulsion and propellers, can achieve 4N in force magnitude and 50-500ms in impulse duration. However, for impact events such as tennis and drumming, current technologies are still 10-100x weaker in force magnitude and 50-500x slower in duration than real-world impact. To address these limitations, we present AirCharge, a novel haptic device that accumulates air propulsion momentum to generate an instantaneous, directional impact force. By mounting compressed air jets on rotating swingarms, AirCharge can amplify impact force magnitude by more than 20x while achieving the same 1-millisecond impulse duration as real-world impact events. To support high-frequency impact, we developed a double swingarm design using a reversing bevel gearbox that eliminates gyro effects and can achieve 10Hz. User experience evaluation comparing air jets with vs. without charging mechanism showed that AirCharge significantly improved realism and is preferred by participants. |
