Title: A METHOD AND A SYSTEM FOR CONTROLLING A COMPUTER AIDED TEXT INPUT BASED ON BRAIN-COMPUTER INTERFACE
Description: The invention pertains to the method and system for controlling text input to aid humans in performing tasks through a brain-computer interface by means of brain activity analysis as a response to visual stimuli. Specifically, it involves a text input control system that obtains an EEG signal from a user, indicating their intention to initiate system operation. The system then provides the user with visual stimuli highlighting separate alphabet characters in sequence, comprising distinct signal cycles associated with character selection. Subsequently, the system captures EEG signal elicited by the visual stimulation, enabling identification of the character selected by the user implementing P300 component analysis.

Title: A METHOD FOR IMPLEMENTING BRAIN-COMPUTER INTERFACE USAGE OUTPUTS AS VISUAL INFORMATION
Description: The invention pertains to a brain computer interface technology that produces visual outputs based on human specific parameters and behaviours, effectively translating individual thought patterns into images. The claimed method for implementing a brain computer interface comprising reading a plot line from EEG outputs; defining a number of plot readings to be used for determining a value of each pixel channel in an image; resizing an image by reading plot values according to the previously defined number of values per pixel channel; obtaining a two-dimensional image from the EEG outputs, wherein each EEG signal is treated as a function y(x) with respective indices, and pixel values for RGB channels are derived from sequential EEG plot values y(x1), y(x), and y(x+1); implementing bidirectional communication by providing an audio visual response based on the generated 2D image; modifying the EEG reading process based on the audiovisual feedback, thereby creating a continuous interaction loop between the EEG and the generated visual and audio outputs.
