In this paper we introduce the Drag'n Go technique to navigate in multi-scale virtual 3d environment. This new technique takes its root from the point of interest (POI) [10] approach where the user selects a target to reach. The biggest difference between the two is that with Drag'n Go the user keeps full control of its position relative to the target as well as its traveling speed. The technique...
This paper evaluates two different interfaces for navigation in a 3D environment. The first is a ‘Click-to-Move’ style interface that involves using a mouse. The second is a gaming style interface that uses both mouse and keyboard (i.e. the ‘WASD’ keys) for view direction and movement respectively. In the user study, participants were asked to navigate a supermarket environment and collect a specific...
In the article, A new method is used to stimulate Three Dimension scene and Two Dimension display. The paper gives one method to show the scene position of three dimension in the two scene display. At the same time, the system also solves the bump problem by using feedback method. Practice show, the system moves well.
We have included 3D sound in our project for enhancing the realism in our virtual environments. Our project allows building different virtual environment multi-screen, with a full navigation system, four ways of manipulating: keyboard, head tracker, remote control and input files with different predefined tours. Furthermore, with this project we can also build two different stereoscopes: Wheatstone-...
Infants double their weight in the first 4 months of life and triple it by the end of the first year. The transition from purely milk intake to solid foods is a key part of a baby's development. Failure to adequately make this transition can severely affect a child's long term development. Virtual reality offers a means of helping instruct parents in appropriate ways of feeding their child, in a safe...
In desktop applications 3D input devices are mostly operated by the non-dominant hand to control 3D viewpoint navigation, while selection and geometry manipulations are handled by the dominant hand using the regular 2D mouse. This asymmetric bi-manual interface is an alternative to commonly used keyboard and mouse input, where the non-dominant hand assists the dominant hand with keystroke input to...
