# 手部追蹤 finger-tracking

由於手把控制器僅能模擬抓握、拖拉轉等粗略動作，而全手追蹤則可偵測每支手指頭的精細動作，賦予手勢操作更多意義。

其中，偵測方式主要可分為兩大類：使用視覺追蹤模組以及配戴穿載式手套：

## [Leap Motion](https://www.leapmotion.com)

Leap Motion發展全手視覺追蹤模組已有多年時間，現已從PC應用轉化至VR應用，過去也有諸多研究採取視覺追蹤方式來達成全手追蹤

## [Dexmo](https://www.dextarobotics.com/en-us)

穿戴式手套的Dexmo 外骨骼機械手指能追蹤 11 個自由度的手部動作，而且在「接觸」虛擬物體時提供相對應的觸覺回饋。

## [VRGluv](https://www.vrgluv.com)

VRGluv同樣也具備完整的手部追蹤系統外與力回饋設計，讓玩家可以在手中感覺虛擬物質。此外具有附件追蹤系統，藉由搭載HTC vive 的追蹤器達到定位效果。
