Why Tolerance in Cultural Diversity is very important for Modern Era Business Environment?(Explain with Examples)

- According to the World Health Organization (WHO) there are 285 million people in the world with visual impairment. Of these, 39 million people are completely blind and 246 million people have low vision. In this modern world science has reached a point where nothing is impossible. Science has made great progress in the field of biotechnology. We have hearing aids for the hearing impaired, robotic arm for the paralyzed person. Scientists have developed this device and the name of that device is Brainport Vision Device. This device is also known as a tasting device because it can savor and detect objects. This device is based on the idea of electro-stimulation for sensory substitution, the process in which if a part of the brain is damaged, then the part of the brain that normally controls the damaged part learns to perform some other function. The device is still under investigation and has not been commercially released, but the results obtained after testing the device on blind people were surprising and have indicated that there is a wide scope of application for this technology in the future.
BrainPort could provide people with vision problems with limited vision. To produce tactile vision, BrainPort uses a camera to capture visual data. Optical information - light that would normally strike the retina - that the camera picks up is in digital form, and uses radio signals to send the zeros to the CPU for coding. Each set of pixels in the light sensor of the camera corresponds to an electrode in the array. The CPU executes a program that converts the camera's electrical information into a spatially encoded signal. The coded signal represents differences in pixel data as differences in pulse characteristics such as frequency, amplitude and duration. Technically, this device is underpinned by a principle called "electro-stimulation for sensory substitution," an area of study that involves the use of electrical current encoded to represent sensory information and apply that current to the skin, which sends the information to the brain.
