Pointer It is a concept that is used in different ways according to context and to the geographical region. It can be about instrument which is used for point something on a screen, a blackboard, a map or other surface. What a pointer allows is for the observer to focus his attention on what is pointed out.
For example: "With a pointer, the general marked the position of the enemy troops and began to explain how the offensive would develop", “My geography teacher couldn't teach the class if I didn't have a pointer on hand”, "The boy took the pointer and hit the teacher in the head", “The manager highlighted the word with the mouse pointer and surprised everyone”.
Specifically, based on that meaning, we should highlight the existence of what is known as laser pointer. It is an elongated device and, as a rule, with the size of a pencil that is identified because at one of its ends it has a system that allows to project a laser light on the desired place.
Currently there are many teachers who use a laser pointer in class, when working with images on the board or projection screens. Since the light of that will help them indicate certain aspects that they want or even point out particularities of images.
However, the use of these pointers has become so widespread that they have become toys. However, that should not be allowed since if the laser they emit is aimed directly at the eyes of another person, it can cause serious damage to their retinas.
In some countries the authorities are quite strict regarding the use of these devices in certain places. And it is that they have been used by individuals lacking coherence both to aim at the eyes of pilots when they were going to take off the planes or even in football stadiums to be able to bother the rival and prevent him from doing his job properly. Thus, for example, Real Madrid footballer Cristiano Ronaldo was the victim of one during a game that faced his then team, Manchester United, with Olympique Lyonnais.
The term is also used to name the person that stands out in a field or to the company of Vanguard : "It is a leading manufacturer in everything that has to do with electronics", “We need to hire a law firm that is leading in these matters”.
On the other hand, the athlete or the team that leads the standings or a team is qualified as a pointer competition : "With this victory, the home team was three points behind the pointer", "The pointer continues to stretch the lead with a new lap record", “Deportivo San Jorge remains an undefeated pointer”.
At soccer , the pointer is a Forward which usually covers the area of the playing field attached to the lateral lines: "The team needs to be reinforced with a left pointer and a central steering wheel", "With two goals from the pointer, Brazil defeated Hungary at the start of the tournament".
Pointer, finally, is the sector, the reinforcement or the patch of a shoe or a stocking that protects the tips of the fingers
