- 1追蹤者、追蹤器（穿戴的運動手環常說「運動追蹤器」）
A tracker is a person who follows an animal or another person by reading the signs they leave behind — footprints, broken branches, ash from a fire. It is skilled work, and the word carries a picture of someone who can look at ground that seems empty to you and say what passed by and how long ago. You meet this sense in stories about hunting, about the American West, about people lost in the bush. The same word has moved into modern life for machines and systems that do the following instead: a GPS tracker on a car, a fitness tracker on your wrist, a bug tracker at work that keeps a list of problems, a solar tracker that turns a panel to face the sun. If a student meets 'tracker' today it is far more likely to be one of these than a person in the forest, so it is worth holding both pictures — a skilled follower, and a device that keeps following something for you.
From the word’s history
From track + -er.
由 track「追蹤」加 -er 組成。
組成track（追蹤、順著痕跡走）+ -er（做這件事的人或東西）。tracker 可以是人，也可以是機器。
