Abstract: Shield means are provided for use on data input apparatus. The shield means includes a housing or frame with at least one channel defined therethrough. The at least one channel has a first end and a second end and is arranged such that a user can view the first channel end in a first position when the user is looking through the second channel end and the user's line of vision is substantially parallel with the longitudinal axis of said channel, thereby allowing data and/or data input means associated with or below the first channel end to be viewed by the user in the first position. The view of the first channel end is substantially obscured or shielded from the user in at least a second position when the user's line of vision is at an acute angle to said channel longitudinal axis.

The display means are arranged in a substantially horizontal orientation and are recessed within a cavity or channel means defined in said device. The walls of the cavity or channel means which define an opening through which a viewer views the display means are arranged substantially perpendicular to said display means.
