Recognition of human individuals
Recognition of acquaintances
From nearby, a human individual is mainly recognized by his or her face. Other differences in appearance are less suitable:
People can also fairly well be recognized by voice. The combination of visual and auditive recognition is even more effective and often removes any doubts.
- usually most of the body is covered with clothing, which varies from day to day;
- body parts other than the face that are uncovered, such as usually hands, are not as easy to tell people apart;
- the arrangement of the hair also helps recognizing people, but, like clothing, a person may vary this, and it may also be covered by headgear.
From longer distances, people can be recognized by their body size and shape and their gait.
