Abstract An effective velocity control technique can enhance sense of presence in an immersive virtual environment (VE) and allow the user to navigate the VE more easily. While many of the existing...

An Evaluation of Techniques for Controlling the Speed of Travel in Immersive V.E. (2008)

Dong Hyun Jeong, Chang Sub Lee, Sang Hyuk Ahn, Chan Young Park, Larry Hodges, Chang Geun Song

While traveling in immersive virtual environments (VEs), a number of navigation techniques are used to enhance one's sense of presence. Velocity control is commonly used to increase...

Differentiation on Information Gathering Ability in Real and Virtual World (2008)

Dong Hyun Jeong, Chang Sub Lee, Gye Bum Jeon, Chang Geun Song, Sabarish Babu, Larry Hodges

Information gathering ability in Virtual Environment (VE) refers to user's ability to learn information such as text, numbers, or annotations. To find the usability of a designed interaction...

Collaboration Infrastructure for a Mobile Situational Visualization System. Available at www.cc.gatech.edu/~dkrum/ papers/krum.collab.pdf. Visited on 06/07/05 (2007)
