Hand open/close generates hand center movement issues RRS feed

  • Question

  • Hi, I am Bo. I am creating an app like system cursors. There is a problem. When hand close and open generates hand center movement. The hand center always moves down a litter bit when hand close. Is there any good solutions for this? Thanks in advanced. I have tried Double Exponential Smoothing filter and Kalman algorithm. They are not work petty well.

  • In general, blending two different interaction concepts, doesn't work well.

    Don't think about using your hand as a cursor because it means you need precision, which gestures destroy.

    Instead, figure out a way to get the hand's general position and use that to highlight UI elements by snapping to it using bounding boxes around the elements and the hand's general position for overlap testing. Depending on the bounding boxes you define it should be easier to blend those together. The concept is to minimize the precision for the cursor within an acceptable threshold to make gestures possible.
