Research Plan for Cloud-Assist VR 2017 2017/01/18

Main Idea Collision detection between players in VR MORPG. VR MORPG (Multiplayer Online RPG) Users experience the virtual world with their avatars. Interact with other players, monsters, and objects in the virtual world. Receive “feedbacks” while the avatar “touches / touched by” another object in the virtual world.

Current Status (Most of the current) MMORPGs do not handle the collisions between user characters. For example, in WoW, characters will be blocked by terrains and objects like rocks and walls. However one can “pass through” other players or monsters in the game. In the current VR games, the controller vibrates when the player is attacked by enemies.

Project Goal Evaluate the amount of resources required to perform collision detection for VR MORPG in the cloud. As a reference for the cloud resource manager.

Target Scenario Given the sensor data from users, detect the collisions between players in VR MORPG on the server. The reason to perform collision detection on server: Reduce the delay and inconsistency incurred by detecting collisions on client computer.

Simplified Version Given a set of spheres / cuboids instead of complex user avatars. Each object moves in the virtual space according to the sensor data from an user. Detect the collisions among these objects.

Work Items Set up the server. Collect sensor data from HMD (and keyboard) on local machine into traces. Survey for the collision detection algorithms/implementations. Evaluation. Resource Usage. (Possible) Optimization. Collision prediction. Speed up using GPU.
