It is common for every child to separate from their parents when they grow up. As we spread our wings, we also left our parents alone with their empty nest. Can we use design to promote communication between children and parents, thereby strengthening the bonding between family members?Dailbox is a long-distance communication device, aims to guide users to put down their phones and start a new face-to-face conversation every night. When the users put their phones on the Dailbox for charging, it will connect with another Dailbox automatically. This project saw the potential of holographic projection in the coming future and trying to create a brand-new chatting experience for the users. Dailbox combining 2D holographic projection and real-time facetime function provides a brand-new conversation experience for the users. It can also record the conversations every time, and replay if the users would like to check their treasured memories in the future, in a holographical way.
