3D Reconstruction is a technology that empower people turn physical objects into high-quality 3D models with the normal RGB camera capturing on mobile device and support for 3D printing. In this project we intend to leverage the technology to portable devices. The challenge of the interaction design is how to offer the user the visual feedback and guidance to capture the entire surface of targeted object through a natural and intuitive way to enhance the user experience to lower the barriers between common consumers and 3D reconstruction. Firstly, we map out the application workflow contain both of systematic backend and user-interface frontend; then we define the visual prompt as a translucent sphere skynet. Based on the augmented reality technology, the sphere could cover the object and blend in environment. According to the dynamic visual guidance and feedback on skynet, user can cover all the segments of the surfaces on the sphere, in the end the capture result could generate 3D models to support scenarios like AR furniture & space arrangement, e-commerce visualization, object recognition & search, etc.
