Communication and control system and method

A method, comprising:

• receiving, by a processor, a first signal from a sensor, the first signal indicative of a gaze direction of a pupil of an eye of a user gazing at at least one of a plurality of visible indicia located at a periphery of the user's field of vision, the plurality of visible indicia establishing a physical reference frame having a plurality of colors and configured to provide a first feedback mechanism;
• identify, based on the first signal, a gazed upon visible indicia, the gazed upon visible indicia being one of the plurality of visible indicia;
• mapping, by the processor, the gazed upon visible indicia to a virtual reference frame comprising a plurality of members of a set;
• identifying a provisional input selection from the plurality of members of the set;
• causing at least one of the first feedback mechanism and a second feedback mechanism to signal that the provisional input selection has been made;
• updating the virtual reference frame if the provisional input selection is not one of a group of predetermined final input selections;
• and
• transmitting a second signal to the second feedback mechanism or to another device to initiate an action based on the provisional input selection if the provisional input selection is one of the group of predetermined final input selections.

A system, comprising:

• a support structure for supporting a plurality of visible indicia such that the plurality of visible indicia is located at a periphery of a user's field of vision, the plurality of visible indicia collectively establishing an external reference frame;
• at least one sensor configured to identify a position of a pupil of an eye;
• and
• a controller communicatively coupled to the at least one sensor and the plurality of visible indicia, the controller configured to:
• display a virtual reference frame on a visual display, the virtual reference frame comprising a matrix comprising a plurality of cells of alphabetic characters,
• receive a first signal from the at least one sensor, the first signal indicative of a first gaze direction of the pupil gazing at at least one of the plurality of visible indicia,
• map the first position of the pupil relative to the external reference frame to a row or column of the virtual reference frame,
• receive a second signal from the at least one sensor, the second signal indicative of a second position of the pupil gazing at at least one of the plurality of visible indicia;
• map the second position of the pupil relative to the external reference frame to the other of a row or column of the virtual reference frame;
• and
• identify a first input selection based on the mapping of the first position and the second position to the virtual reference frame, the first input selection being, of the plurality of cells, the cell corresponding to the row and column selected by the user.
