We compared four different methods of travel in an immersive virtual environment and their effect on cognition using a between-subjects experimental design. The task was to answer a set of questions based on Crook's condensation of Bloom's taxonomy to assess the participants' cognition of a virtual room with respect to knowledge, understanding and(More)
We report a series of experiments conducted to investigate the effects of travel technique on information gathering and cognition in complex virtual environments. In the first experiment, participants completed a non-branching multilevel 3D maze at their own pace using either real walking or one of two virtual travel techniques. In the second experiment, we(More)
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). Participants answered a set of questions based on Crook's condensation of Bloom's taxonomy that assessed their cognition of the IVE with respect to knowledge, understanding and(More)
We investigated the effects of using immersive virtual humans to teach users social conversational verbal and non-verbal protocols in south Indian culture. The study was conducted using a between-subjects experimental design, and compared instruction and interactive feedback from immersive virtual humans against instruction based on a written study guide(More)
Two experiments examined how 10- and 12-year-old children and adults intercept moving gaps while bicycling in an immersive virtual environment. Participants rode an actual bicycle along a virtual roadway. At 12 test intersections, participants attempted to pass through a gap between 2 moving, car-sized blocks without stopping. The blocks were timed such(More)
This paper reports on a study that compares three different methods of travel in a complex, multi-level virtual environment using a between-subjects design. A real walking travel technique was compared to two common virtual travel techniques. Participants explored a two-story 3D maze at their own pace and completed four post-tests requiring them to remember(More)
People with vestibular dysfunction often complain of having difficulty walking in visually complex environments. Virtual reality (VR) may serve as a useful therapeutic tool for providing physical therapy to these people. The purpose of this pilot project was to explore the ability of people with and without vestibular dysfunction to use and tolerate virtual(More)
Few experiments have been performed to investigate near-field egocentric distance estimation in an Immersive Virtual Environment (IVE) as compared to the Real World (RW). This article investigates near-field distance estimation in IVEs and RW conditions using physical reach and verbal report measures, by using an apparatus similar to that used by Bingham(More)
We describe an empirical study of Marve, a virtual receptionist located at the entrance of our research laboratory. Marve engages with lab members and visitors in natural face-to-face communication, takes and delivers messages , tells knock-knock jokes, conducts natural small talk on movies, and discusses the weather. In this research, we investigate the(More)
1 Motivation and Related Works 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 expensive and inconvenient. In addition, privacy might be an issue for some patients who are not comfortable closely interacting with(More)
