The fundamental question for an information-rich virtual environment is how to access and
display abstract information. We investigated two existing navigation techniques: hand …

When a user is in close proximity to a robot, physical contact becomes a potentially valuable
channel for communication. People often use direct physical contact to guide a person to a …

Standalone augmented reality (AR) systems have great potential for interactive three-
dimensional (3D) geo-visualization. Emerging head-worn AR technologies can display rich …

User behaviors while navigating virtual environments (VEs) using head-mounted displays
(HMDs) were investigated. Particularly, spatial behaviors were observed and analyzed with …

Players in computer games continue to rely on assistance for navigation in the game
environment, even after hours of gameplay. This behavior is in contrast to the real world …

In this dissertation, we present typical components of, useful services associated with, and
user interactions possible with mobile augmented reality systems, based on a …

Navigational tools are relied on to traverse unfamiliar grounds, but their use may come at a
cost to situational awareness and spatial memory due to increased cognitive load. In order …

The position-tracking accuracy of a location-aware mobile system can change dynamically
as a function of the user's location and other variables specific to the tracker technology …

During free exploration of an unknown virtual scene, users often miss important parts,
