Estimating Spatial-Interaction Models
Environment and Planning A: Economy and Space, 1978The problems that arise when estimating the unknown parameters of models of spatial interaction are considered. Two models are analysed and the large-lattice theory outlined. The need for a small-lattice theory is discussed, and those aspects of the theory that distinguish it from the large-lattice theory are emphasized.

Environment and Planning A: Economy and Space, 1972
This paper centres on the development of a geometrical representation of movement and spatial interaction in urban areas, as distinct from the network representation commonly used in modern studies. All quantities are treated as distributions over geographic space, rather than concentrations at nodes of a network.

3D interfaces use motion sensing, physical input, and spatial interaction techniques to effectively control highly dynamic virtual content. Now, with the advent of the Nintendo Wii, Sony Move, and Microsoft Kinect, game developers and researchers must create compelling interface techniques and game-play mechanics that make use of these technologies. At

CHI '07 Extended Abstracts on Human Factors in Computing Systems, 2007
Mobile phones are starting to become the major platform for interaction with spatial information. Recent research has yielded promising applications and approaches for exploring, accessing and augmenting information related to the user's immediate surroundings. The CHI workshop "Mobile Spatial Interaction" (MSI) aims at gathering researchers working on

Industries are complex because many factors are involved in their operation. It is not possible to get information on all of these variables so that a study of industry is necessarily incomplete. Some of the factors may be distributed at random such as business acumen or personal caprice. If all the factors are randomly distributed or if those that are

Neural Spatial Interaction Models
2001One of the major intellectual achievements and, at the same time, perhaps the most useful contribution of spatial analysis to social science literature has been the development of spatial interaction models. Spatial interaction can be broadly defined as movement of people, commodities, capital and/or information over geographical space (see Batten and ...

Structural Spatial Interaction∗
The Professional Geographer, 1993This paper identifies a concept of structural spatial interaction. Although it is defined differently from its counterpart of structural unemployment in economics, it attempts to define a similar idea. In economics, the focus is on equilibrium in the supply and demand of labor.

Spatial Autocorrelation and Spatial Interaction
2015Definition:Spatial interaction refers to all cases in which a relationship (a flow of persons, goods, communications, citations, and so on) is observed between pairs of spatial units. Differently from the standard areal or point units often analyzed in spatial science, spatial interaction data are denoted by their bilateral nature.

Spatial Autocorrelation in Spatial Interaction
2009Carey (1858) and Ravenstein (1885) first proposed, through analogy, the gravity model of Newtonian physics as a description for economic and social spatial interaction, with Sen and Smith (1995) furnishing a comprehensive treatment of this model more than a century later.

ABSTRACT The lack of good flow data is a handicap to spatial interaction researth, yet many published works provide little evaluation of such data. Good quality flow data should provide spatial coverage at a large scale with small sampling and other error components.
