1. A system for reducing data entry errors, comprising: an input component controllable to display a plurality of keys selectable by a user in accordance with a controllable viewing mode, the input component receiving input by the user; a display component controllable to display one or more key images; a processor operatively coupled to the input component and the display component, and programmed to: control the display component to display a key image or images corresponding to key selection input by the user on the input component; ascertain a subset of the keys selectable by the user based upon respective likelihoods that each of the keys follows a previously selected key or keys within a predetermined language or subset thereof; define the controllable viewing mode so that the input component displays each of the keys within the ascertained subset of keys in a manner visually distinguishable by the user from each of the keys not within the ascertained subset of keys; control the input component to display the plurality of keys selectable by the user in accordance with the controllable viewing mode as defined by the processor; define the controllable viewing mode so that the input component is controlled to display each of the keys within the ascertained subset of keys in a three-dimensional format that includes a top surface and side surfaces, and to display each of the keys not within the ascertained subset of keys in a three-dimensional format that includes a bottom surface and side surfaces.

The system of claim 1 , wherein a target area of each of the keys corresponds to the respective top surface of the key displayed by the input component.
