Imagine this: you and your friend are on a video call. He or she picks up a book, and you feel like you’re holding the book as well. You can shake hands or give your friend a high five, even though you’re apart (分开).

A pair of special gloves might make this come true. Researchers at the University of New South Wales, Australia, have made gloves that can recreate the sense of touch. They call this haptic device (触觉装置) a “soft skin stretch device” (SSD).

The SSD works like this: One user’s gloves create 3D force signals when they touch something. The signals are sent to the other user’s gloves, which vibrate (震动) to create the same force that the first user is experiencing. This allows the second user to experience the same sense of touch.

The SSD allows you to feel force, vibration and motion(移动). “It is like wearing a second skin,” said Thanh Nho Do, one of the researchers who created the gloves.

Haptic technology is already being widely used. For example, the trackpads (触控板) in laptops (平板) use vibration to make it feel like you’re clicking (点击) a real mouse. However, it is difficult to recreate the sense of touch in virtual (虚拟的) environments or remotely (远程地), according to Mai Thanh Thai, lead researcher of the SSD project. The SSD is special because it has a high level of sensitivity (灵敏度) even when it is used continuously (连续地). This makes it feel more realistic (真实的).

The SSD could be used in medical practice. Two doctors in separate places could work together during an operation (手术)—one touches the patient’s organs (器官) with the SSD while the other doctor feels the same sensation (感觉) and completes the actual (实际的) operation.
