用的是kinect,捕捉到人,将人手的point加入到id中,用tuioServer模拟器,模拟多点触摸.tuioServer是保存id中的位置,比如记录下你的左手id为1,那么在你左手不消失前,id不变,id中的point在改变,只要不断update里面id的point即可.下面为关键代码,引用了TuioServer

                    //过期的点
                    var delPoints = pointableIDs.Where(pointableID => NowPointIDs.All(m => m != pointableID)).ToList();
                    //循环删除过期的点
                    foreach (var pointableID in delPoints)
                    {
                        tuioServer.DeleteTuioCursor(pointableID);
                        pointableIDs.Remove(pointableID);
                    }
                    //更新
                    tuioServer.CommitFrame();
                    //每次遍历完后,添加这次获取到的id值,清空原来的值
                    NowPointIDs = new List<int>();
                    if (skeletonFrame != null)
                    {
                        //linq语法,查找离kinect最近的,被跟踪的骨骼
                        skeletonFrame.CopySkeletonDataTo(frameSkeletons);
                        var currentSkeletons = (from s in frameSkeletons
                                                where s.TrackingState == SkeletonTrackingState.Tracked && s.Joints[JointType.Head].TrackingState == JointTrackingState.Tracked
                                                //select s).OrderBy(s => s.Joints[JointType.Head].Position.Z).FirstOrDefault();
                                                select s).Take(MaxSkeletonTrackingCount).ToList();
                        if (currentSkeletons.Any())
                        {
                            //将点添加到list集合
                            for (var k = 0; k < currentSkeletons.Count(); k++)
                            {
                                //只获取到一只手??
                                HandsPoint[2 * k] = GetJointPoint(currentSkeletons[k].Joints[JointType.HandRight]);
                                NowPointIDs.Add(2 * k);
                                HandsPoint[1 + 2 * k] = GetJointPoint(currentSkeletons[k].Joints[JointType.HandLeft]);
                                NowPointIDs.Add(1 + 2 * k);
                                Title = HandsPoint[2 * k].ToString() + HandsPoint[1 + 2 * k].ToString();
                                if (pointableIDs.Any(m => m == 2 * k))
                                {
                                    tuioServer.UpdateTuioCursor(2 * k, new PointF((float)HandsPoint[2 * k].X, (float)HandsPoint[2 * k].Y));
                                }
                                else
                                {
                                    pointableIDs.Add(2 * k);
                                    tuioServer.AddTuioCursor(2 * k, new PointF((float)HandsPoint[2 * k].X, (float)HandsPoint[2 * k].Y));
                                }
                                if (pointableIDs.Any(m => m == 1 + 2 * k))
                                {
                                    tuioServer.UpdateTuioCursor(1 + 2 * k, new PointF((float)HandsPoint[1 + 2 * k].X, (float)HandsPoint[1 + 2 * k].Y));
                                }
                                else
                                {
                                    pointableIDs.Add(1 + 2 * k);
                                    tuioServer.AddTuioCursor(1 + 2 * k, new PointF((float)HandsPoint[1 + 2 * k].X, (float)HandsPoint[1 + 2 * k].Y));
                                }

                            }
