3D brain-click using binocular display

A computing system, comprising:

• at least one display device;
• a neural signal capture device configured to detect neural activity of a user;
• one or more processors;
• and
• a memory storing instructions that, when executed by the one or more processors, cause the computing system to perform operations comprising:
• presenting a first visual stimulus stereoscopically to the user's eyes with a first modulation via the at least one display device, the first visual stimulus being presented at a first virtual depth perceived by the user's depth perception and overlapping a first position within a field of view of the user;
• presenting a second visual stimulus stereoscopically to the user's eyes with a second modulation via the at least one display device, the second visual stimulus being presented at a second virtual depth perceived by the user's depth perception and overlapping the first position within the field of view of the user, such that the first and second visual stimuli occupy a common angular region of the field of view at different virtual depths;
• obtaining neural signals of the user via the neural signal capture device;
• in response to determining, based on the neural signals, that the user's eyes are focused on the first visual stimulus by determining a strength of components of the neural signals having a property associated with the first modulation, placing the computing system into a first state associated with the first visual stimulus;
• and
• in response to determining, based on the neural signals, that the user's eyes are focused on the second visual stimulus by determining a strength of components of the neural signals having a property associated with the second modulation, placing the computing system into a second state associated with the second visual stimulus.

A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors of a computing system, cause the computing system to perform operations comprising:

• presenting a first visual stimulus stereoscopically to a user's eyes with a first modulation, the first visual stimulus being presented at a first virtual depth perceived by the user's depth perception and overlapping a first position within a field of view of the user;
• presenting a second visual stimulus stereoscopically to the eyes with a second modulation, the second visual stimulus being presented at a second virtual depth perceived by the user's depth perception and overlapping the first position within the field of view of the user, such that the first and second visual stimuli occupy a common angular region of the field of view at different virtual depths;
• obtaining neural signals from a neural signal capture device configured to detect neural activity of the user;
• in response to determining, based on the neural signals, that the user's eyes are focused on the first visual stimulus by determining a strength of components of the neural signals having a property associated with the first modulation, placing the computing system into a first state associated with the first visual stimulus;
