UNITY3D中調(diào)用WISEGLOVE數(shù)據(jù)手套的方法

    本文介紹了在UNITY3D中調(diào)用WISEGLOVE數(shù)據(jù)手套的方法。 通過該方法可以讀取手套的傳感器角度值和傳感器原始值，可以根據(jù)需求執(zhí)行進一步應用。本程序調(diào)用了WISEGLOVE SDK， 并對SDK的主要函數(shù)作了調(diào)用聲明。

    在UNITY3D中使用WISEGLOVE虛擬現(xiàn)實數(shù)據(jù)手套可分為三步：

    1. 在Start ()中 初始化手套

    2. 在Updata()中循環(huán)讀取傳感器數(shù)據(jù)（數(shù)值或者角度）

    3. 關(guān)閉手套調(diào)用端口

    // 聲明：本范例程序適合WiseGlove數(shù)據(jù)手套，如需了解WiseGlove數(shù)據(jù)手套，請訪問www.wiseglove.com
