Introduction

Direction Sense is the ability to know a person’s current location and then finding the correct way towards the destination.

It involves determining all the contextual information such as an individual's location, activity, the time of day, and proximity to other people or objects and devices and mapping the location and direction mentally which is known as cognitive mapping.


Direction Classification

Directions are mainly classified as:

  • Cardinal directions

  • Diagonal directions

Cardinal directions are North, South, East, and West.

Diagonal directions are NorthWest, NorthEast, SouthWest, and SouthEast.

diagonal direction

The cardinal directions and the diagonal directions together are called compass directions that are displayed in the form of a compass rose.

Direction can also be classified as Vertical directions, that is, ‘Up’ and ‘Down’ and Relative directions, that is, ‘In’ and ‘Out’. Non-standard directions are listed below:

The four shipboard directions: fore, aft, port, and starboard.

The four other relative directions or facing directions: left, right, forward, and back.

The four disk directions or wheel directions, that have no standard names - hubward, rimward, clockwise, and counterclockwise.

On a space station, you might use spinward and antispinward. The two very rarely-used fourth dimension directions: ana and kata.

Furthermore, the direction is graded like the mid-compass direction "north-northeast", the diagonal shipboard direction "Foreport", or the tilted-compass direction "UpNorth" is there, however as these directions are so incredibly rare, they are nearly non-existent.

Directional commands are common in the International Federation that most of the standard directions have abbreviations in English as:

N is the short form of NORTH
S is the short form of SOUTH
W
is the short form of WEST
E
is the short form of EAST
NW
is the short form of NORTH-WEST
NE
is the short form of NORTH-EAST
SW
is the short form of SOUTH-WEST
SE
is the short form of SOUTH-EAST
U
is the short form of UP
D
is the short form of DOWN 


Finding Direction

The basic process of finding direction involves four stages:

map

  • Orientation - It is the act of determining one's location, with landmarks, objects, situations nearby, and the planned destination.
  • Route decision - It is the selection of a track of direction to the destination.
  • Route monitoring - It is the act of checking periodically to ascertain that the selected route is heading towards the destination.
  • Destination recognition - It is when the proper destination is successfully recognized.

Identification of the direction in respect of a person who has moved in different direction:

  1. During sunrise, while a man stands facing the East, his shadow will fall towards the west.
  2. During sunrise, while a man stands facing the North, his shadow will fall on his left.
  3. During sunrise, while a man stands facing the South, the shadow will fall on his right.
  4. During sunrise, while a man stands facing the West, the shadow will fall towards the West.

  1. During sunset, while a man stands facing the North, his shadow will fall on his right.
  2. During sunset, while a man stands facing the East, his shadow will fall towards the East.
  3. During sunset, while a man stands facing the sun, towards the West, his shadow will fall towards the East.
  4. During sunset, while a man stands facing the South, his shadow will fall on his left.
