Industrial Design:

First, we encountered a challenge on projecting the silhouette that clearly represents the person bowing inside the screen. The more detailed it gets, the less clarity it showed. So, we contour sketched the side view of the person on a neutral posture and bowing posture. It worked our perfect as the silhouette perfectly projected the difference in the posture.

Second, the challenge was measuring the distance between the human and the axis. The closer it gets, the other person who is not supposed to show up inside the screen showed up. But, if we made it longer, the human supposed to be on the screen was not perfectly in the middle, but tilted to the side. So, we went over several dimensions starting from 100%, 90%, 80%, to 70%. Trying different dimension and manipulating distance between axis, we finally came up with right size and distance.

Other than the projection screen, most work was dealing with constructing the 'stage' that gratitude rock might sit on, and making a cube shaped space so that the source of light can effectively project the RGB LED.
