Brain computer interface (BCI) enables users to control computers and other devices with their thoughts. BCIs monitor the user’s brain activity, translate it into commands that can be used to operate the device, and provide feedback to the user in order to allow him or her to correct the inputs that caused errors.
The most widely used method for building BCIs involves the use of electrodes that are connected to the body or head to record brain signals. The digital signals are then examined to determine the relevant signal characteristics that correspond to the user’s intent. The features that are extracted can include EEG or ECoG response magnitudes and latencies, as well as power within certain EEG or ECoG frequency bands or firing rates of individual cortical neurons.
As shown by our survey people are enthusiastic about the prospect of applying BCI technology for a variety https://hive-eu.org of purposes. It is clear that BCI researchers must be aware of the concerns expressed by the public, as well as their own experts to ensure the responsible growth of this emerging technology.
There are many major challenges that remain one of the most important is the improvement of BCI reliability. For real-life practicality, the BCI must be as reliable as muscle-based actions. This requires an CNS that is sufficiently flexible to allow the BCI to recognize and generate the desired commands. The other issue is the cost of invasive BCIs, that require both initial and ongoing implantation and technical support costs. If these costs cannot be substantially reduced, the commercial value of the BCI could be limited to those with the greatest disability.
