The New Reference Frame about the Spatial Orientation Expression for Way-finding
نویسندگان
چکیده
Orientation relationship in the spatial relationship is an important in GIS. The orientation information about the urban environment is directly available to human beings through perception and is crucial for establishing their spatial location and for way-finding. People perceive the arrangement (layout) of entities in space, categorize them as spatial relationships, and describe them as spatial expression in language. This paper will propose the new type of the reference frame and its orientation system, and demonstrate the composition factors and the characteristic of the reference frames. We will illustrate its mathematics base and its formalization expression in mathematics. Then we will analyze some characteristics to make way-finding in such reference frame. In the conclusion, we suggest the further research about the orientation relation of the new reference frame.

Qualitative Directions in Egocentric and Allocentric Spatial Reference Frames
In this paper, we have presented a formalism for representation of and reasoning about directions in a qualitative way in two spatial reference frames, namely, an egocentric reference frame and an allocentric reference frame. Qualitative direction has been separated from dimensionality of spatial objects and as such, the formalism may be used to represent qualitative direction in a dimension-in...
متن کاملConstructing a Body-Fixed Reference Frame for a Polyatomic Molecule
An attempt is made to show in a straightforward way how a body-fixed frame may be constructed in classical and hence in quantum mechanics for a polyatomic molecule with the aid of which the vibration-rotation behavior of the molecule may be described.
متن کاملCoordinate frame for symmetry detection and object recognition.
Can subjects voluntarily set an internal coordinate frame in such a way as to facilitate the detection of symmetry about an arbitrary axis? If so, is this internal coordinate frame the same as that involved in determining perceived top and bottom in object recognition and shape perception? Subjects were required to determine whether dot patterns were symmetric. Cuing the subjects in advance abo...
متن کاملImpeller and volute design and optimization of the centrifugal pump with low specific speed in order to extract performance curves
Now a day centrifugal pumps are vital components of industries. Certainly, one of the most important specifications of centrifugal pumps are the performance curves. In the present work, performance curves of a centrifugal pumps are obtained by Computational fluid dynamics (CFD) and as an outcome, CFD results compare by practical curves. At the first step impeller and volute are designed with tw...
متن کاملCognitive Constraints in Spatial Reasoning: Reference Frame and Reference Object Selection
If someone says "the cup is in front of the teapot", is the cup between the speaker and the teapot, is the cup at the spout end of the teapot, or both? In order to resolve this ambiguity, you would need to know whether the speaker was using a reference frame based on his/her viewpoint (deictic) or on the objects in the scene (intrinsic). As well, why did they locate the cup in relation to the t...
