ABSTRACT

When we are required to change from a straight ahead direction we are most oen informed by an arrow pointing le or right. However, when we are required to continue in the same forward direction, there is no single agreed symbol (concept-related glyph). Generally, for forward direction we use either an arrow pointing upwards (most oen) or an arrow pointing downwards (less oen). In multilevel environments, up arrows and down arrows can also be interpreted as ‘go up’ or ‘go down’. This adds another problem to the issue. It is evident that what is the most common direction of movement on earth, albeit not the most signposted one, does not have a unique and commonly agreed symbol to represent it.
