Tactile sensation equipment helps people to "obey"

Release date: 2009-04-21





Recently, researchers at the Massachusetts Institute of Technology's Perceptual Communication Group have developed a haptic device that translates sound waves into shocks that the skin can feel by “transducing” the subtleties of speaking, thus overcoming the swearing of the lips. The obstacles to discourse cannot be clearly identified, and the device is several orders of magnitude lower than cochlear implant surgery. The study was funded by the National Institutes of Health.

It is reported that Ted Morum, a researcher in the Perceptual Exchange Group, and Charlotte Reid, a senior researcher at the Massachusetts Institute of Technology's Electronic Research Laboratory, are developing software that is compatible with current smartphones and can turn such devices into low-key. The tactile aids are better for the deaf to "obey". Morem said that anyone with a smartphone can run this program, which also includes a microphone and a basic vibration system. The haptic device translates the sound waves into vibrations, and the user can distinguish between vibration modes associated with different sound frequencies. The equipment the researchers are currently testing has at least two vibration ranges of high frequency sound and low frequency sound.

Lip language refers to interpreting what others say by looking at the movements of lips when others are talking. For many monks, reading lip language is a form of communication, but reading lip language has an obvious flaw: some consonants such as p and b are almost impossible to distinguish only by observation. With such a handheld device, the deaf person can communicate easily and simply, and the lip language needs to be highly concentrated, and in the case of a highly concentrated state, it is difficult to conduct casual conversations.

Researchers say that the current machine can be placed in the hands of the user or hung around the neck. Once the sound processing software is developed, it can be easily integrated into the existing intelligent software. Researchers are currently considering how to better Transform sound waves into vibrations. They have done several studies on the frequency acceptance of the skin. The human ear can receive frequencies above 20,000 Hz, but the optimal receiving frequency of the touch sensors in the skin is below 500 Hz. Using a laboratory device with a device that provides a clear vibration mode, Morumm made a preliminary study of the ability to translate shocks from haptic devices.

The project was first provoked by Reid's research on Tadoma, a method of communication between the blind and the blind. When the blind and the monk are talking, the user of the method touches the hand. Other people's faces to feel the vibration of the other's face and neck. Twenty years ago, Rhett's research proved that deaf and blind people can successfully use this method to understand each other, especially when the other person speaks clearly and speaks slowly.
