For example, computer vision and object based indexing can be used to both identify an object and assist a user in navigating from the location. Spatial contextual awareness plays a key role in this process as it provides an initial geo-reference of the location while simplifying the object recognition process to a manageable degree. [14]
Spatial memory is required to navigate in an environment. In cognitive psychology and neuroscience, spatial memory is a form of memory responsible for the recording and recovery of information needed to plan a course to a location and to recall the location of an object or the occurrence of an event.

A key property of visual attention is that attention can be selected based on spatial location and spatial cueing experiments have been used to assess this type of selection. In Posner's cueing paradigm , [ 4 ] the task was to detect a target that could be presented in one of two locations and respond as quickly as possible.
An object-based spatial database is a spatial database that stores the location as objects. The object-based spatial model treats the world as surface littered with recognizable objects (e.g. cities, rivers), which exist independent of their locations. Objects can be simple as polygons and lines, or be more complex to represent cities.
Spatial ability is the capacity to understand, reason and remember the visual and spatial relations among objects or space. [1] There are four common types of spatial abilities: spatial or visuo-spatial perception, spatial visualization, mental folding and mental rotation. [3]
A spatial map needs to be acquired according to a frame of reference. Because it is independent from the observer's point of view, it is based on an allocentric reference system— with an object-to-object relation. It codes configurational information, using a world-centred coding system.
Location is generally broken down into distance from the observer and direction (left/right, front/back, high/low). Dimension refers to the object's height (tall or short) and breadth (wide or narrow). By understanding the interrelationships of these qualities, much can be perceived about the nature of an object or multiple objects.
Location-based service (LBS) is a general term denoting software services which use geographic data and information to provide services or information to users. [1] LBS can be used in a variety of contexts, such as health, indoor object search, [2] entertainment, [3] work, personal life, etc. [4] Commonly used examples of location-based services include navigation software, social networking ...
