    Hi guys,

    I want to detect the point, during a hand swing motion, when the arm aligns or comes to the level of shoulder like the 1st, 3rd and 5th ones in the figure.
    Could using an accelerometer work? If yes how would I position the sensor as the arm could be rotated in any way about its own axis and not necessarily be like in the figure.
    A design constraint is that I can place sensors on the arm only nothing on the shoulder.

    Thanks in advance.

    An accelerometer measures acceleration, not position. It is imho therefore not suitable.

    Would you be comfortable using a camera, a PC and some gesture recognition software that you'd have to program yourself based on e.g. the OpenCV library?

    Gyroscope sensor might do it.

    I don't think there is a simple solution for this. In particular, one that only requires a device attached to the arm.

    @Amar Dhore Can you please tell me the placement of Gyroscope and How will it work?
