Systems and methods for processing data entered using an eye-tracking system

A keyboard comprising:

• a plurality of data input keys, wherein each input key is associated with at least one input data value and at least one data input key is a multi-value key associated with at least two input data values;
• an eye-tracking system for determining an area where a user is gazing by monitoring an eye movement of the user, wherein the eye-tracking system determines an area covering portions of at least two of the plurality of data input keys;
• and
• an input value selection module coupled to the plurality of data input keys and to the eye-tracking system;
• wherein the input value selection module determines which input data value was entered based on a manually pressed data input key and on the area where the user is gazing.

A method for processing data entered at a keyboard having a plurality of keys associated with an input data value, the plural of keys including at least one multi-value key associated with at least two input data values, the method comprising:

• assigning a unit to each key;
• assigning a plurality of units to each multi-value key, wherein each input data value corresponds to at least one unit;
• determining an area where a user is gazing by tracking the user's eye movement;
• detecting a manual selection of one of a key and a multi-value key;
• and
• determining probabilistically an input data value entered based on a value received from at least one unit and on the area where the user is gazing.

A method for processing data entered at a keyboard having a plurality of data input keys, each data input key being associated with at least one input data value and at least one data input key being a multi-value key associated with at least two input data values, the method comprising:

• determining an area where a user is gazing by tracking the user's eye movement, wherein the area covers portions of at least two data input keys;
• detecting a manual selection of a data input key;
• and
• determining which input data value was entered based on the manually pressed data input key and on the area where the user is gazing.

A non-transitory computer readable medium containing program instructions for entering data using a keyboard having a plurality of data input keys, wherein each data input key is associated with at least one input data value and at least one data input key is a multi-value key associated with at least two input data values, the computer readable medium comprising program instructions for:

• determining an area where a user is gazing by tracking the user's eye movement, wherein the area covers portions of at least two data input keys;
• detecting a manual selection of a data input key;
• and
• determining which input data value was entered based on the manually pressed data input key and on the area where the user is gazing.
