The Brain Computer Interface (BCI) allows users to control computers, and other devices, by using their thoughts. BCIs record the user’s brain activity and translate it into commands that can be used to operate the device, and then provide feedback to the user to allow him or her to correct the inputs that caused errors.
Presently, the https://hive-eu.org/linking-the-human-mind-to-a-machine most popular methods for creating BCIs are the use of electrodes that are attached to the head or body to capture signals from the brain. These digital signals are examined to determine the relevant signal features that are in line with the user’s intentions. These features could include EEG or ECoG response magnitudes and latencies, as well as power within specific EEG or ECoG frequency bands or firing rates of individual cortical neurons.
Based on our survey the public is enthusiastic about the possibility of using BCI technology for a variety of purposes. It is clear that BCI researchers must address the concerns raised by the public, as well as their own experts to ensure the an ethical growth of this new technology.
The most significant challenge that is still to be solved is increasing the reliability of BCI. A BCI must be as reliable in real-world situations as muscle-based actions. This requires significant CNS plasticity which allows the BCI to develop the ability to recognize and execute the desired commands. The other issue is the substantial cost of invasive BCIs, which require ongoing and initial implantation and technical support costs. If these costs are not substantially reduced, commercial practicality of a BCI could be restricted to those with the greatest disability.
