Why can't I use a two finger gesture to resize an image at the wall?

If you use one hand to make a pinching gesture to resize an image, the image may jitter or fail to resize. This is because the pinching gesture can create a shadow between your two fingers which blocks the laser curtain from detecting touch properly. To avoid this, use one finger from each hand and drag them your hands apart to enlarge the image. Drag your hands closer together to reduce the size of the image.
