Abstract
A human-computer interface system and method for target selection on a computer-generated display includes an eye-tracking unit configured to capture gaze patterns of a user, a neural signal capture unit configured to detect neural signals (such as electroencephalogram (EEG) signals) from the user, and a processing unit. The processing unit is configured to analyze the gaze patterns and neural signals to identify an anticipatory negative potential associated with the user's intent to select a particular target, and to initiate a target selection based on the identified anticipatory negative potential.
Claims20
A human-computer interface system for selecting a target presented on a display, the system comprising:
- an eye-tracking unit configured to capture gaze patterns of a user;
- a neural signal capture unit configured to detect neural signals dependent on brain electrical activity from the user;
- and
- a processing unit configured to:
- analyze the gaze patterns to identify user fixation on a particular displayed target,
- analyze the neural signals to identify an anticipatory negative potential associated with the user's intent to select the particular target;
- and
- initiate a target selection of the particular target based, at least partially, on the identified anticipatory negative potential.
A method for selecting a target presented on a display, comprising the steps of:
- capturing gaze patterns of a user using an eye-tracking unit;
- detecting neural signals of the user using a neural signal capture unit;
- analyzing the gaze patterns and neural signals to identify an anticipatory negative potential associated with the user's intent to select a particular target;
- and
- initiating a target selection of the particular target based, at least partially, on the identified anticipatory negative potential.
A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform a method for selecting a target presented on a display, the method comprising the steps of:
- receiving gaze patterns of a user from an eye-tracking unit;
- receiving neural signals of the user from a neural signal capture unit;
- analyzing the gaze patterns and neural signals to identify an anticipatory negative potential associated with the user's intent to select a particular target;
- and
- initiating a target selection of the particular target based, at least partially, on the identified anticipatory negative potential.
