Social navigation Social navigation can also be discussed in different types of virtual worlds. Munro shares some original conceptions when considering social navigation. One of them is, instead of individual interaction, it can be presented as "a way of moving through an information space and exploiting the activities and orientations of others in that space as a way of managing one's spatial activities". Munro also points out that spatial navigation, which mostly depends on the structure itself, like landscape or map, can be contrasted with social navigation. User may even have interactions not only with the data and objects in this specific space, but also other individuals and their interactions with it.
Navigation mesh Navigation meshes in video game artificial intelligence are usually credited to Greg Snook's 2000 article "Simplified 3D Movement and Pathfinding Using Navigation Meshes" in "Game Programming Gems". In 2001, J.M.P. van Waveren described a similar structure with convex and connected 3D polygons, dubbed the "Area Awareness System", used for bots in "Quake III Arena".
Navigation Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation.
Memory and social interactions Evolutionary psychologists have shown that memories for social interactions are subject to natural selection. As demonstrated through free recall and recognition tasks, humans are able to discern between cooperators and cheaters in social interactions.
Navigation Navigation, in a broader sense, can refer to any skill or study that involves the determination of position and direction. In this sense, navigation includes orienteering and pedestrian navigation. For information about different navigation strategies that people use, visit human navigation.

Interactions is venture-backed by Sigma Partners, Cross Atlantic Capital Partners, Updata Partners, North Hill Ventures, Revolution Growth, NewSpring Capital, and Comcast Ventures. Michael Iacobucci serves as Interactions' CEO. Interactions has additional offices in Indianapolis, Indiana (Corporate/Technology Center), and Austin, Texas (Technology Center).
3D interaction A simple 2D mouse may be considered a navigation device if it allows the user to move to a different location in a virtual 3D space. Navigation devices such as the treadmill and bicycle make use of the natural ways that humans travel in the real world. Treadmills simulate walking or running and bicycles or similar type equipment simulate vehicular travel. In the case of navigation devices, the information passed on to the machine is the user's location and movements in virtual space.
Navigation By mental navigation checks, a pilot or a navigator estimates tracks, distances, and altitudes which then will help him or her avoid gross navigation errors.
Memory and social interactions Memory underpins and enables social interactions in a variety of ways. In order to engage in successful social interaction, people must be able to remember how they should interact with one another, whom they have interacted with previously, and what occurred during those interactions.
3D user interaction 3D Interaction Techniques are the different ways that the user can interact with the 3D virtual environment to execute different kind of tasks. The quality of these techniques has a profound effect on the quality of the entire 3D User Interfaces. They can be classified into three different groups: Navigation, Selection and manipulation and System control.
Navigation The Day's work in navigation is a minimal set of tasks consistent with prudent navigation. The definition will vary on military and civilian vessels, and from ship to ship, but takes a form resembling:
Mersey and Irwell Navigation The company in charge of the navigation was known by several names. These include "The Old Navigation", "Old Quay Company", and "Old Quay Canal".
3D interaction In 3D interaction, users carry out their tasks and perform functions by exchanging information with computer systems in 3D space. It is an intuitive type of interaction because humans interact in three dimensions in the real world. The tasks that users perform have been classified as selection and manipulation of objects in virtual space, navigation, and system control. Tasks can be performed in virtual space through interaction techniques and by utilizing interaction devices. 3D interaction techniques were classified according to the task group it supports. Techniques that support navigation tasks are classified as "navigation techniques". Techniques that support object selection and manipulation are labeled "selection and manipulation techniques". Lastly, "system control techniques" support tasks that have to do with controlling the application itself. A consistent and efficient mapping between techniques and interaction devices must be made in order for the system to be usable and effective. Interfaces associated with 3D interaction are called "3D interfaces". Like other types of user interfaces, it involves two-way communication between users and system, but allows users to perform action in 3D space. Input devices permit the users to give directions and commands to the system, while output devices allow the machine to present information back to them.
Volume Interactions Pte Ltd Volume Interactions Pte Ltd was a company that pioneered in the 1990s the use of virtual surgery planning. This was done by means of its product the Dextroscope, which used Virtual Reality technology (a two-handed 3D user interface, stereoscopic displays) to provide a natural interface to plan surgical approaches for patients using multi-modality 3D medical images. The company was a spin-off company from the Kent Ridge Digital Labs research institute in Singapore. The company was founded in 2000 in Singapore and acquired by the Bracco Group in 2002. Volume Interactions ceased commercial operations in 2008.
Navigation Inertial navigation system is a dead reckoning type of navigation system that computes its position based on motion sensors. Once the initial latitude and longitude is established, the system receives impulses from motion detectors that measure the acceleration along three or more axes enabling it to continually and accurately calculate the current latitude and longitude. Its advantages over other navigation systems are that, once the starting position is set, it does not require outside information, it is not affected by adverse weather conditions and it cannot be detected or jammed. Its disadvantage is that since the current position is calculated solely from previous positions, its errors are cumulative, increasing at a rate roughly proportional to the time since the initial position was input. Inertial navigation systems must therefore be frequently corrected with a location 'fix' from some other type of navigation system. The US Navy developed a Ships Inertial Navigation System (SINS) during the Polaris missile program to ensure a safe, reliable and accurate navigation system for its missile submarines. Inertial navigation systems were in wide use until satellite navigation systems (GPS) became available. Inertial Navigation Systems are still in common use on submarines, since GPS reception or other fix sources are not possible while submerged.
Magellan Navigation Magellan develops and distributes vehicle navigation, crossover GPS, and outdoor handheld navigation products. The Company also produces customized mapping software for topographic, marine, and street navigation.
Mersey and Irwell Navigation The Mersey and Irwell Navigation was a river navigation in North West England, which provided a navigable route from the Mersey estuary to Salford and Manchester, by improving the course of the River Irwell and the River Mersey. Eight locks were constructed between 1724 and 1734, and the rivers were improved by the construction of new cuts several times subsequently. Use of the navigation declined from the 1870s, and it was ultimately superseded by the Manchester Ship Canal, the construction of which destroyed most of the Irwell section of the navigation and the long cut between Latchford and Runcorn.
Calder and Hebble Navigation By the beginning of the 18th century, the Aire and Calder Navigation had made the River Calder navigable as far upstream as Wakefield. The aim of the Calder and Hebble Navigation was to extend navigation west (upstream) from Wakefield to Sowerby Bridge near Halifax.
3D user interaction Navigation is the most used by the user in big 3D environments and presents different challenges as supporting spatial awareness, giving efficient movements between distant places and making navigation bearable so the user can focus on more important tasks. These techniques can be divided into two components: travel and wayfinding.
E-Navigation The combination of the five e-navigation solutions, and the three guidelines, "Guidelines on Human Centred Design (HCD) for e-navigation", "Guidelines on Usability Testing, Evaluation and Assessment (U-TEA) for e-navigation systems" and "Guidelines for Software Quality Assurance (SQA) in e-navigation", proposes an e-navigation implementation that facilitates a holistic approach to the interaction between shipboard and shore-based users.
