The convergence of bio-signals in neuroscience has been a topic of interest for researchers for many years. Neuroscience has made significant strides in understanding the human brain and its functions. The use of bio-signals, such as electroencephalography (EEG), magnetoencephalography (MEG), functional magnetic resonance imaging (fMRI), and positron emission tomography (PET), has been instrumental in advancing the field of neuroscience. Integrating these bio-signals allows for a more comprehensive understanding of brain function. Integrating bio-signals has been particularly useful in studying brain disorders such as epilepsy, Alzheimer's, and schizophrenia. For example, EEG has been used to diagnose epilepsy and monitor patients' responses to treatment. MEG has been used to study the neural mechanisms underlying Alzheimer's disease. fMRI has been used to study the effects of antipsychotic medication on brain function in patients with schizophrenia. Integrating bio-signals has also helped study cognitive processes, such as attention, perception, and memory. For example, EEG has been used to study attentional processes, while fMRI has been used to study memory retrieval. Integrating these bio-signals has allowed researchers to gain a more complete understanding of these cognitive processes. The convergence of bio-signals has also been helpful in the development of brain-computer interfaces (BCIs) and virtual reality (VR) systems. BCIs allow individuals to control devices using their brain activity. The integration of multiple bio-signals can improve the accuracy and reliability of BCIs. VR systems allow individuals to interact with virtual environments. The integration of bio-signals can provide a more immersive VR experience. Despite the advantages of integrating bio-signals, there are also challenges. One challenge is the need for accurate and precise synchronization of the different bio-signals. This requires specialized equipment and software. Another challenge is the need for data analysis techniques to handle the integrated bio-signals complexity and variability.

When compared to conventional keyboards, virtual touch screen keyboards provide less accuracy and agility. Furthermore, people are still unable to perceive the controls. The fundamental purpose of this research is to develop a key template that fits precisely with human finger motors and operates well with cognitive processing brain. Reaction time variability was utilized to compute the time, and human psychological variables were considered for this assembly pattern surface. The interface design also validates external BCI aspects such as human long term and short-term cognition, computer vision, eye gazing, and hue personal integrity to adjust with the reader so that the viewer may acclimatize with the interface and operate error less high-speed fluent typing.
