Multi-user is important in Augmented Reality to share experiences
Multi-user is important in Augmented Reality to share experiences
- Each user controls a cube
- A red capsule goes back and forth between the first and second user cubes
- A web server manages ip addresses for use over a LAN
- A heartbeat call to the server is made every 3 sec for each user
- Each user has a list of other ips
- Each user sends cube position and orientation to each ip each frame
- Each user receives other cube positions and orientations and updates game objects each frame
- Low latency

Clouded Data
- Ip, device name, timestamp are stored in PongAR.txt on the web server
- Ip managment occurs every 3 seconds
- Cube position and orientation data is shared separately each frame

- upload_ip.php takes three arguments and is called by the Unity app
- ip, device, timestamp are the arguments
- Each Unity app calls every 3 seconds, timeout is 5 sec
- Each call checks for expired (elapsed time > 5sec) and removes entries
- Current caller's data is added
- List of ips is returned delimited by ":"
- Heartbeat calls update the active ip list
- Heartbeat accomplishes network discovery on a local network using a web server
- Game object position is sent to one or more ip's
- Positions and orientations of remote ip's are received and game objects are updated
- Each Unity app updates game object positions and orientations
