Do we have a movement signature?
As humans, we have several qualities that separate us from one another, such as our fingerprints.
According to a recent study, each person has a unique movement signature (鲜明特征). Depending on the person, these differences can be subtle or pronounced.
For the study, scientists attached electrodes (电极) to muscles in the legs of volunteers. The volunteer were then asked to perform activities such as walking on walking machines and riding stationary bikes (健身车), which were adjusted according to each person's physical appearance in order to make sure everyone was judged using the same standards.
Scientists fed the information to a computer along with the volunteer's name. Next, the computer was fed information without the user's name and it could identity the person correctly 99% of the time. The outcomes of the study showed that each of us does have something unique about our general movements.
Since this is just a pilot study, scientists will do more tests to see if the signature changes with age and weight changes. But with a deeper understanding of the science of movement, doctors could possibly develop more intricate prosthetics (复杂精细的假肢). Whether that's cool or frightening is up to you to decide.
A. How could this study be of use to scientists?
B. What do you think of the findings of the study?
C. Volunteers are expected to write a report on the activities.
D. Is it possible that we also have unique qualities in our movement.
E. Scientists could also program robots to copy humans' movements more exactly.
F. In this way, the computer could learn the unique movement quality of each person.
G. The study was conducted by inviting people to take part in a couple of physical activities.
