Project Overview
- This project allows 2 users use 2 android phones to connect to each other by TCP, then they can navigate and interact to each other in a virtual world. Both users use first-person-view to view the world, they can change their viewing direction by rotating the phone if the phone has gyroscope.
- Explanation of the picture: The triangle in the left phone represents the orientation and position of right phone.
Status
Implemented
- TCP connection between 2 phones and periodically update the information of the world( including the status of dynamic objects and status of the other user)
- Change viewing direction by gyroscope
- Built the scene by OpenSceneGraph for android phones.
- Users can do some actions on dynamic objects (such as open a door) and the other user can see the change.
- Allow users to press buttons to move their position
To-do
- Allow user to create geometries in the world and other users can see the created geometries
- Maybe try to use a PC as server to allow more than 2 users to connect, the loading might be too heavy for one phone to be a network server for many clients.
- Model modification support
- The translation computed by double integral of acceleration (acceleration data is retrieved from accelerometer of the phone) is not accurate enough due to the noise and the real-time requirement. Need to use other approaches to compute translation.
