Brain-computer interface with adaptations for high-speed, accurate, and intuitive user interactions

A non-transitory processor-readable medium storing code representing instructions to be executed by a processor, the instructions comprising code to cause the processor to:

• generate a control interface configured to be manipulated, by a user, to perform a set of actions;
• generate and present a stimulus, via the control interface and to the user, the stimulus including a set of control items, each control item from the set of control items being associated with an action from a set of actions, the set of control items;
• receive information from an eye-tracking device including eye-movement signals associated with the user, the eye-tracking device;
• determine, based on the information from the eye-tracking device, a point of focus of the user;
• identify a first control item, from the set of control items, associated with the point of focus of the user at a first time;
• provide a grabber object included in the control interface, the grabber object being configured to manipulate a sticky control item included in the set of control items;
• identify the first control item as a sticky control item configured to be (1) transitioned to a picked-up state in response to an eye-movement signal indicating a foveation on the sticky control item, (2) moved based on the user's eye-movement signal, and (3) transitioned to a dropped state on a target control item to activate the target control item;
• associate, when the sticky control item is at the picked-up state and based on the sticky control item being associated with the point of focus of the user at the first time, the sticky control item with the grabber object;
• determine a point of focus of the user at a second time after the first time,
• identify a second control item associated with the point of focus of the user at the second time, the second control item being different from the sticky control item;
• dissociate, when the sticky control item is at the dropped state and on the second control item, the sticky control item from the grabber object and associate the sticky control item with the second control item;
• and
• determine, based on the association between the sticky control item and the second control item, an action intended by the user.

A method, comprising:

• presenting, to a user, at a first time period, a stimulus via an control interface, the stimulus including control items associated with a set of actions, the control items including a sticky control item configured to be (1) transitioned to a picked-up state in response to a foveation of the user on the sticky control item, (2) moved based on an eye-movement signal of the user, and (3) transitioned to a dropped state on a target control item to activate the target control item;
• receiving, from an eye-tracking device, a first set of inputs including eye-movement signals of the user at the first time period;
• identifying, based on the eye-movement signals, a foveation over a sticky control item;
• transitioning the sticky control item to the picked-up state in response to the foveation over a sticky control item;
• associating the sticky control item with a grabber object configured to manipulate the sticky control item;
• determining a point of focus of the user at a second time after the first time,
• identifying a second control item associated with the point of focus of the user at the second time, the second control item being different from the sticky control item;
• transitioning the sticky control item to the dropped state;
• dissociating, when the sticky control item is at the dropped state and on the second control item, the sticky control item from the grabber object and associating the sticky control item with the second control item;
• and
• determining, based on the association between the sticky control item and the second control item, an action intended by the user.
