Haptic interfaces enable us to interact with virtual objects by sensing our actions and communicating them to a virtual environment. A haptic interface with force feedback capability will provide sensory information back to the user thus communicating the consequences of his/her actions. The quality and complexity of these interactions is dependent on how the interface is designed. When designi...

When we comprehend language, we often do this in rich settings where we can use many cues to understand what someone is saying. However, it has traditionally been difficult to design experiments with rich three-dimensional contexts that resemble our everyday environments, while maintaining control over the linguistic and nonlinguistic information that is available. Here we test the validity of ...

This paper describes a study of using the concept of augmented reality for supporting assembly line workers in carrying out their task optimally. By overlaying virtual information on real world objects – and thereby enhance the human’s perception of reality – augmented reality makes it possible to improve the visual guidance to the workers. In the study, a prototype system is developed based on...

The ability to challenge and revise thoughts prompted by anomalous experiences depends on activity in right dorsolateral prefrontal circuitry. When activity in those circuits is absent or compromised subjects are less likely to make this kind of correction. This appears to be the cause of some delusions of misidentification consequent on experiences of hyperfamiliarity for faces. Comparing the ...

This paper examines combinations of complementary evaluation methods as a strategy for efficient usability problem discovery. A data set from an earlier study is re-analyzed, involving three evaluation methods applied to two virtual environment applications. Results of a mixed-effects logistic regression suggest that usability testing and inspection discover rather disjunctive sets of problems....

Immersive authoring refers to the style of programming or developing content from within the targetexecutable environment. Immersive authoring is important for fields such as augmented reality (AR) in which interaction usability and user perception of the target content must be checked first hand, in situ. In addition, the interaction efficiency and usability of the authoring tools itself is eq...

This paper discusses experience and technical issues in teaching a virtual course in the IT area which integrates lecture, tutorial and laboratory material. The lectures are based on multimedia material consisting of Web documents complemented with audio material allowing students to attend virtual lectures online. An integrated Web-based tutorial and lab service provides a dynamic illustration...

This is a white paper outlining a methodology for employing collaborative, immersive virtual environments as a high-end visualization interface for massive data-sets.

We present a study of interactive virtual reality visualizations of scientific motions as found in biomechanics experiments. Our approach is threefold. First, we define a taxonomy of motion visualizations organized by the method (animation, interaction, or static presentation) used to depict both the spatial and temporal dimensions of the data. Second, we design and implement a set of eight exa...

This paper proposes a mobile augmented reality system that allows Mexican secondary education students to access additional educational contents related to their textbooks. Our system recognizes the images printed in the book as part of regular taught topics and shows multimedia contents that complement the topics covered in the book. These contents are generated through a service-oriented arch...
