Experiences in Extemporaneous Incorporation of Real Objects in Immersive Virtual Environments (2009)

Benjamin Lok

We present our experiences in developing, and user responses in experimenting with, virtual environments that can dynamically incorporate (visualize and interact with) real objects. We have found...

IEEE TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS, TVCG-0144-1104 1 Comparison of Path Visualizations and Cognitive Measures Relative to Travel Technique in a Virtual Environment (2009)

Catherine Zanbaka, Benjamin Lok, Sabarish Babu, Amy Ulinski, Larry F. Hodges

Abstract — We describe a between-subjects experiment that compared four different methods of travel, and their effect on cognition and paths taken in an immersive virtual environment (IVE)....

General Terms (2008)

Aaron Kotranza, John Quarles, Benjamin Lok

For simulating hands-on tasks, the ease of enabling two-handed interaction with virtual objects gives Mixed Reality (MR) an expected advantage over Virtual Reality (VR). A user study examined whether...

Abstract (2008)

Benjamin Lok, Samir Naik

We present our experiences in developing, and user responses in experimenting with, virtual environments that can dynamically incorporate (visualize and interact with) real objects. We have found...

Interpersonal Scenarios: Virtual � Real? (2008)

Robert Dickerson, Benjamin Lok, Marc Cohen, Amy Stevens, Shands Va Hospitals, Thomas Bernard, ...

This paper reports on a study to examine the similarities and differences in experiencing an interpersonal scenario with real and virtual humans. A system that allows medical students to interview a...

Applying Virtual Reality in Medical Communication Education: Current Findings and Potential Teaching and Learning Benefits of Immersive Virtual Patients (2008)

Benjamin Lok, Richard E. Ferdig, Andrew Raij, Kyle Johnsen, Robert Dickerson, Jade Coutts, ...

The purpose of this paper is to summarize a theoretical perspective toward the development of a virtual reality innovation in education. Next, we will describe a virtual character project that is...

The validity of a virtual human experience for interpersonal skills education (2007)

Kyle Johnsen, Andrew Raij, Amy Stevens, D. Scott Lind, Benjamin Lok, Ph. D

Any new tool introduced for education needs to be validated. We developed a virtual human experience called the Virtual Objective Structured Clinical Examination (VOSCE). In the VOSCE, a medical...

Evolving an immersive medical communication skills trainer. Presence: Teleoperators and Virtual Environments (2006)

Robert Dickerson, Andrew Raij, Cyrus Harrison, Benjamin Lok, Amy Stevens, D. Scott Lind

This paper presents our experiences in evolving the Virtual Objective Structured Clinical Exam (VOSCE) system. This system allows medical students to experience the interaction between a patient and...

A Pipeline for Rapidly Incorporating Real Objects into a Mixed Environment (2005)

Xiyong Wang, Aaron Kotranza, John Quarles, Benjamin Lok

A method is presented to rapidly incorporate real objects into virtual environments using laser scanned 3D models with color-based marker tracking. Both the real objects and their geometric models...

Virtual patients: Assessment of synthesized versus recorded speech (2005)

Robert Dickerson, Kyle Johnsen, Andrew Raij, Benjamin Lok, Amy Stevens, Thomas Bernard, ...

Abstract. Virtual patients have great potential for training patient-doctor communication skills. There are two approaches to producing the virtual human speech: synthesized speech or recorded...

Virtual human physiotherapist framework for personalized training and rehabilitation (2005)

Sabarish Babu, Catherine Zanbaka, Jonathan Jackson, Taeoh Chung, Benjamin Lok, Min C. Shin, ...

For patients recovering from injuries, or individuals that require a system to provide feedback on aspects of exercise performance, physical therapy sessions with a professional trainer can be...

Incorporating Dynamic Real Objects into Immersive Virtual Environments (2003)

Benjamin Lok

We present algorithms that enable virtual objects to interact with and respond to virtual representations, avatars, of real objects. These techniques allow dynamic real objects, such as the user,...

Incorporating Dynamic Real Objects into Immersive Virtual Environments (2003)

Benjamin Lok

Suppose one has a virtual model of a car engine and wants to use an immersive virtual environment (VE) to determine whether both a large man and a petite woman can readily replace the oil filter....

Online model reconstruction for interactive virtual environments (2001)

Benjamin Lok

We present a system for generating real-time 3D reconstructions of the user and other real objects in an immersive virtual environment (IVE) for visualization and interaction. For example, when parts...
