A group of researchers in China have created an innovative system Help move more autonomy and protection to the blind. It is a small visual assistant formed by a joint committee of Jiao Tong University in Shanghai, and the University of Hong Kong Science and Technology University, which combines many advanced technologies.
How does it work?
Like the computer A virtual fact that suits the real lifeIt combines multiple components to guide the user. In them, we see some 3D camera mirrors It is obstacles in the environment and a Artificial .
It is a OsteogistIt sounds directly to the skull without blocking the ears Training Virtual truthThis allows the system to learn and recognize safe ways 82 types of objectsAs reported from the magazine, even in the variable conditions Nature.
Instead of using speaking messages, The system releases frozen but subtle soundsIt has a clear object and does not complete the person. In this way, this is not annoying or confusing Allows you to go naturally. During a test in the environment with obstacles, the 100% Blind or low -sighted persons who used this method Record Turn it successfully.
The results of the trusted
Compared to those who used only sugarcane, The conflicts were reduced by 67%He Navigation time is 25% at least And March speed remained intact Rather than traditional methods.
Although the results are confident, the system is not yet correct. In an application level (SUS), it received a score of 79.6 approximately 100. This is a high note, however there is still space to improve.
