Many navigation techniques have been tried out and implemented by many researchers. However, their research is focused on the navigation techniques themselves (how to turn, how to move forward/backwards, how to change the speed of travel, etc.), and not on how precise the navigation is in complex virtual environments when many turns need to be taken to reach a destination. In addition, in many ...

As the basic and ubiquitous elements of interfaces, navigation is used to search target information items. Many prior research has shown that how does the navigation placement influence users’ visual search efficiency and preference, and owing to the format of navigation is hierarchical navigation in most of e-commerce websites today. So designers need to consider about the navigation configura...

Writing navigation expressions is an important part of the task of developing a model transformation de nition. When navigation is complex and the size of source models is signi cant, performance issues cannot be neglected. Model transformation languages often implement some variants of OCL as their navigation language. Writing e cient code in OCL is usually a di cult task because of the nature...

Navigation and search are two general ways to retrieve information on the web. The usability and utility of web navigation have a direct impact on information seeking efficiency and the success of a website. There are basically two ways to improve web navigation designs. One is to improve the webpage design and content organization of the website; web usability studies have offered plenty of gu...

The purpose of this study was to examine whether matching navigation mode of a learning environment with learners’ preferred navigation mode would facilitate their learning in a web environment. Sixty-eight undergraduate students were randomly assigned to treatments (linear vs. nonlinear navigation mode) and received four criterion tests designed to measure different educational objectives imme...

Learning is like navigation in space. Human declarative learning has a spatial navigation basis. The evidence for this comes from animal navigation research and human brain studies. The two forms of navigation correspond to two forms of declarative memory and this has implications for instructional design.

Physical rotations and translations are the basic constituents of navigation behavior, yet there is mixed evidence about their relative importance for complex navigation in virtual reality (VR). In the present experiment, 24 participants wore head-mounted displays and performed navigational search tasks with rotations/translations controlled by physical motion or joystick. As expected, physical...

Existing user performance models of navigation for very large documents describe trends in movement time over the entire navigation task. However, these navigation tasks are in fact a combination of many sub-tasks, the details of which are lost when aggregated. Thus, existing models do not provide insight into the navigation choices implicit in a navigation task, nor into how strategy ultimatel...

Mobile entity navigation in dynamic environments is an essential part of many mission critical applications like search and rescue and fire fighting. The dynamism of the environment necessitates the mobile entity to constantly maintain a high degree of awareness of the changing environment. This criteria makes it difficult to achieve good navigation performance by using just on-board sensors an...

Preliminary communication Automation of navigation at sea has partly been provided for with the use of integrated navigation bridge − INB. The functioning of INB is supervised by the officer who also takes the final decision during navigation. The complete automation of navigation can be improved by upgrading the existing equipment on board modern ships. To provide for automation of inland navi...
