Our idea come from a science fiction movie. We want to make a product that can change people’s boring life into a new world. Thus, we create a new world in a virtual reality device, named BigDanny. Whenever you feel lonely or boring, you can just go into the world of BigDanny. It let you become a person with magic power. In the BigDanny, you can have a chance to make friends with other people. After some people becoming your friends, you could team up with them and explore BigDanny together. With this device, you can also do exercise in home, which make you become a healthier person not only on the mental but also on the physical. Finally, your life will be interesting.
