User interface apparatus capable of providing support to user
Necessity/no necessity for user support (such as enlarged display) is registered for each user or for each screen displayed on the apparatus. A user using the apparatus is specified by means of user authentication. Every time the screen is to be displayed, it is done based on information of necessity/no necessity for user support that has been registered. Thus, operability for the user can be improved.

in a situation where said executing portion is incapable of executing a certain type of support, said execution portion executes another type of support.
10 . The user interface apparatus according to claim 9 , wherein
said situation where said executing portion is incapable of executing a certain type of support is a situation where a screen with a support function used by the user shifts to a screen without support, and upon such a situation, said executing portion informs the user of the shift to the screen without support, and executes alternative support according to the user.
11 . The user interface apparatus according to claim 1 , wherein
said execution of support is at least one of: display of a screen being different in size of characters; display of a screen being different in colors to be displayed; and provision of an audio guide.
12 . A control method for a user interface apparatus having a displaying portion capable of displaying a plurality of types of screens, comprising:
a determining step determining whether or not support is necessary for a user at each of said plurality of types of screens; and
an executing step executing support in displaying on said displaying portion, in accordance with a result of the determination at said determining step.
13 . A control program product for a user interface apparatus having a displaying portion capable of displaying a plurality of types of screens, causing a computer to execute:
a determining step determining whether or not support is necessary for a user at each of said plurality of types of screens; and
an executing step executing support in displaying on said displaying portion, in accordance with a result of the determination at said determining step.
14 . A user interface apparatus, comprising:
a displaying portion for displaying a first screen;
an instructing portion for instructing to display a next screen on the displaying portion by a user;
a selecting portion for selecting one of plurality of screens, which are different types respectively, as the next screen, corresponding to the user; and
a display control portion for controlling the displaying portion so that the displaying portion displays the next screen selected by the selecting portion.
15 . The user interface apparatus according to claim 14 , wherein the plurality of screens are similar but nonidentical in their respective contents to be displayed.
16 . The user interface apparatus according to claim 14 , wherein the plurality of screens are different in size of characters to be displayed at respective screens.
