Brain Computer Interfaces is about the real time applications with the usage of the processor by name DSP. This Presentation provides in detail information regarding the interfaces of Brain-Computer and also about the processor DSP and also usage of them in the real time applications.
The brain-computer interfaces helps in establishing the direct communication path between the human and an external device. The history of it has started in the year of 1970 where the first development involved in accepting the brain waves as the input.
There exist many methods for the reading of the brain which includes the Direct Neural Contact which provides high accuracy, it is also high invasive but it not supported with the current technologies which can be possible in future.
When we consider the other method of the Electroencephalogy it is used for measuring the electric activity in the brain. It is cost effective, east to implement and also portable. These are considered to be mostly used device in case of BCIs. It is considered as Non-invasive.
When we consider the method of Magnetoencephalogy it is used for measuring the magnetic fields of the brain. Provides high accuracy, but it requires the high equipment’s and also includes the maintenance costs. It is considered as Non-invasive.
In case of this method Functional Magnetic Resonance Imaging, it is used for measuring the flow of the blood in the brain using the MRI. It is used for studing the function of the brain. It is a very accurate method.
We can conclude that it provides the interfaces of Brain-Computer and the implementation is done in the real time applications.
