Video calls are a common occurrence, but have you imagined being able to touch the person on the other end of the line? Scientists are making this a reality.
Researchers at the University of new South Wales, Australia have invented a soft skin stretch device(SSD). A haptic device that can recreate the sense of touch. Haptic technology mimics the experience of touch by stimulating localized areas of the skin in ways that are similar to what is felt in the real world, through force, vibration or motion.
Vibration is the most common haptic technology today and has been built into many electronic devices such as one attached to the back of the trackpad( 触摸板 ) in laptops, which simulates a button clicking. However, haptic feedback with vibration becomes less sensitive when used continuously. The existing technology also has great difficulty recreating the sense of touch with objects in virtual environments or located remotely. According to Mai Thanh Thai, lead author of the study.
The new technology overcomes issues with existing haptic devices. The research team introduced a novel method to recreate the sense of touch through a soft artificial “muscles”.
“Our three-way directional skin stretch device, built into the fingertips of the wearable glove we also created is like wearing a second skin-- its soft stretchable and mimics the sense of touch-- and will enable new forms of haptic communication to enhance everyday activities”said Thanh Nho Do, senior author of the study.
Imagine you are at home and you call your friend who is in Australia. You wear a haptic glove with the SSDs, and your friends also wears a glove with integrated 3D force sensors. If your friend picks up an object, it will physically press against your friend’s fingers. And their glove with 3D force sensors will measure with interactions. The force signals can be sent to your glove so your device will generate the same 3D forces. Making you experience the same sense of touch as your friend.
The haptic devices could be applied in various situations, allowing users to feel objects inside a virtual world or at a distance. It could also be used in medical practices. Doctors can feel a patient's organ tissues. With surgical tools without touching them.

【分析】
本文是一篇说明文。文章主要介绍一种可以重现触觉的设备。
1 .推理判断题。根据第二段 “Haptic technology mimics the experience of touch by stimulating localized areas of the skin in ways that are similar to what is felt in the real world ,through force ,vibration or motion.” (触觉技术通过刺激局部皮肤的方式来模拟触摸的体验,这种方式类似于在现实世界中通过力量、振动或运动所感受到的感觉。)和第四段的 “The new technology overcomes issues with existing haptic devices. The research team introduced a novel method to recreate the sense of touch through a soft artificial “muscles”.” (这种新的技术克服了现有触觉设备存在的问题。小酒小组引进了一个新的方法,通过柔软的人造 “ 肌肉 ” 来重建触觉)可推知,这篇文章暗示 SSDs 可以在不振动的情况下重现触觉。故选 B 。
2 .主旨大意题。根据第六段,尤其是 “If your friend picks up an object, it will physically press against your friend’s fingers. And their glove with 3D force sensors will measure with interactions. The force signals can be sent to your glove so your device will generate the same 3D forces. Making you experience the same sense of touch as your friend. ” (如果你的朋友拿起一个物体,它就会挤压你朋友的手指。他们的手套带有 3D 力传感器,可以测量相互作用。力信号可以发送到你的手套上,这样你的设备就会产生同样的 3D 力。让你体验到和你朋友一样的触觉。)可知,第六段主要告诉我们这个装置是如何工作的。故选 A 。
3 .推理判断题。根据最后一段 “The haptic devices could be applied in various situations. allowing users to feel objects inside a virtual world or at a distance. It could also be used in medical practices. Doctors can feel a patient's organ tissues. With surgical tools without touching them.” (触觉装置可以应用于各种场合。允许用户在虚拟世界中或在远处感受物体。它也可以用于医疗实践。医生可以感觉到病人的器官组织。用手术工具而不接触它们。)由此可知,作者对 SSDs 的前景非常乐观。故选 D 。
4 .主旨大意题。纵观全文,尤其根据第二段中 “Researchers at the University of new South Wales, Australia have invented a soft skin stretch device(SSD). A haptic device that can recreate the sense of touch.” (澳大利亚新南威尔士大学的研究人员发明了一种柔软皮肤拉伸设备 (SSD) 。一种可以重现触觉的触觉设备。)由此可知,本文主要介绍一种可以重现触觉的设备。故选 C 。
