Aivokonerajapinnat, often referred to as Brain-Computer Interfaces (BCIs), are systems that facilitate direct communication pathways between the brain and an external device. These interfaces enable individuals to control computers or other assistive technologies using their brain activity alone. BCIs typically work by detecting and analyzing neural signals, such as electrical activity measured by electroencephalography (EEG) or other neuroimaging techniques. These signals are then translated into commands that can be interpreted by an external device.

The development of BCIs is driven by a desire to restore or augment human capabilities, particularly for individuals with severe motor disabilities or neurological disorders. Potential applications range from controlling prosthetic limbs and wheelchairs to communication aids and even immersive virtual reality experiences. Research in this field is multidisciplinary, involving neuroscience, engineering, computer science, and medicine.

There are two main categories of BCIs: invasive and non-invasive. Invasive BCIs require surgical implantation of electrodes directly into the brain, offering higher signal resolution but carrying greater risks. Non-invasive BCIs, such as those using EEG caps, are safer and easier to use but generally provide less precise signal data. Despite ongoing challenges in signal processing, accuracy, and user training, BCIs represent a rapidly advancing frontier with significant potential to transform lives.
