A method for processing data entered using an electronic device and an electronic device capable of implementing the method is described. In one embodiment, the electronic device includes at least one multi-value key associated with at least two input data values. Each multi-value key includes a plurality of units and each input data value corresponds to at least one unit. The electronic device also includes an eye-tracking system that determines an area where a user is gazing by monitoring eye movements of the user, and an input value selection module coupled to the plurality of units and to the eye-tracking system. The input value selection module determines probabilistically which input data value was entered based on a value received from at least one unit and on the area where the user is gazing.
