Kinect v1に接続できます

Question

私はUbuntu 14.04でAffectiva https://developer.affectiva.com/の無料感情認識バージョンのプロジェクトを持っています。 私はKinect v1をAffectivaの入力デバイスとして使用しようとしています。 kinect v1のIDがBus 003のデバイス009：ID 045e：02ae Microsoft Corp.のXbox NUI Camera。aff intx cameraId = 045e：02aeをaffdex-sdk/CameraDetector.hおよびbuild/opencvで修正しようとしています-webcam-demo。

、まだKinectのV1に接続できませんでしたデモプログラムを実行していますopencv-webcam-demo kinect v1をAffectivaの入力として使用する方法はありますか？

現在、KinectプラットフォームをサポートするSDKはありません。
