Angle direction between joints Kinect sdk ver 1.5 RRS feed

  • Question

  • Hello All,

    I calculated the angles between the skeleton joints in which the angle is calculated based on the parent bone as shown in the attached images, the problem is that the angle is calculated without a sign determining its direction whether  its upwards "+ve" or "-ve" downwards, and I need to detect this or put a sign for example +ve if upwards and -ve if downwards,
    As shown in the attached pics the first pic shows the angle = 4, then if i moved upwards the angle will be 45 and if i moved downwards the angle will be 48 not -48, all what i need to know is how to differentiate and the direction of movement in which the angle will be +angle if upwards and -ve angle if downwards.

  • try to make the joint's angel depends some how on the Postion.X and Position.Y because they are got in signed number

    so you could calculate it is up or down angel
