Self-reflection: In this bridge, I feel creating an AR technology is difficult. The way of setting up the 3D shape to a 3D modeling, it takes many of time. In addition, when I create AR, there are many problems coming out. For example, how to build up a 3D model and how to upload other tags into the mark. Overall for designing this “memoir” in past, present, and future which makes me think more and deep on the object that I care in the past to the future. The AR technology that I made is successful and I’m surprised what I made in AR.
