Abstract
An artificial reality system includes a head mounted display (HMD) and a hand-held device. A virtual boundary can provide for user safety during an artificial reality session. For example, the virtual boundary may be defined to protect the user from collisions with physical objects, such as walls, furniture, or the like, while the user is immersed in the artificial reality session. The artificial reality system can constrain the predicted motion path of a portion of a user's body based on body configuration parameters and range of motion of the joints associated with the body portion. The artificial reality system can then use the constrained motion paths to determine whether or not the virtual boundary warning should be activated.
