Brain activity signal input device control

A non-transitory machine-readable medium comprising instructions executable by a processor of a computing device to:

• map a first brain activity signal received from a non-invasive electroencephalography (EEG) device associated with a first of four body movements to control of an input device,
• wherein the input device is a keyboard or a mouse;
• responsive to the mapping of the received first brain activity signal to control of the keyboard, iteratively map subsequently received brain activity signals associated with the four body movements to control a group of keys of the keyboard associated with the subsequently received brain activity signals until a first desired output is reached,
• wherein the first desired output is reached in a threshold number of stages;
• and
• responsive to the mapping of the received first brain activity signal to control of the mouse, iteratively map subsequently received brain activity signals associated with the four body movements to control a set of mouse movements or mouse actions associated with the subsequently received brain activity signals until a second desired output is reached,
• wherein the second desired output is reached in the threshold number of stages.

A non-transitory machine-readable medium comprising instructions executable by a processor of a computing device to:

• receive a brain activity signal from a non-invasive electroencephalography (EEG) device, wherein the brain activity signal represents one of four body movements,
• wherein the one of the four body movements is associated with a particular command;
• map the brain activity signal to control an input device based on the particular command,
• wherein the input device is a keyboard or a mouse;
• subsequently receive up to three brain activity signals representing up to three of the four body movements and associated with up to three particular commands;
• responsive to the mapping of the received brain activity signal to control of the keyboard, map the up to three subsequently received brain activity signals to control groups of keys of the keyboard based on the up to three particular commands associated with the up to three of the four body movements;
• and
• responsive to the mapping of the received brain activity signal to control a set of mouse movements or mouse actions, map the up to three subsequently received brain activity signals to control a set of mouse movements or mouse actions based on the up to three particular commands associated with the up to three body movements.
