Chapter
Virtual Reality (VR) enables users to interact with a simulated environment through a head-mounted device (HMD) and two hand controllers. These help in tracking the user’s head and hand locations and movements but have no references to the rest of the body. Though these movements can be tracked using additional equipment like trackers and bodysuits...

We propose a multi-modal approach to manipulating smart home devices in a smart home environment simulated in virtual reality. Our multi-modal approach seeks to determine the user’s intent in the form of the user’s target smart home device and the desired action for that device to perform. We do this by examining information from two main modalitie...
Chapter
The term ‘storage’ in real life typically refers to a container that occupies physical space, such as rooms, closets, warehouses, etc. Our interactions with items stored within are constrained by physics in real life. However, Virtual Reality allows us to ignore certain rules. Inspired by a Bag of Holding from Dungeons & Dragons and other entertain...

Virtual Equipment System is a system in extended reality that provides the user with equipment slots and equipment that serve as an interface for further interactions. The equipment slots are storage locations for equipment that is associated with the user spatially (egocentric). Due to the virtual nature of the system, these egocentric equipment s...
Chapter
Text Entry is a significant topic in human-computer interaction in Virtual Reality. Most common text entry methods require users to interact with a 2D QWERTY keyboard in 3D space using a ray emitting from their hands or controllers. This requires the user’s head and hands to be in a specific position and orientation to do text entry. We propose a n...

Analyzing player experience often requires collecting lots of gameplay data from human players, which is labor-intensive. In this paper, we present an approach to classify player experience using AI agents. A deep Reinforcement AI agent is deployed to learn abstract representation of game states. Then, machine learning models are trained with the a...
Conference Paper
Player-Game interaction can be viewed as a sequence of game events between game systems and players. In each event, a piece of information (for example, a game challenge) is presented to the player, and the player responds to that information by executing proper in-game actions. Since different games have different systems and mechanics, it is diff...
