Question 28/I - Symbols, pictograms, and keypad layout
(revision and continuation of Question 8/II and
incorporation of Question 13/II from 1985-1988)

Considering

(a) that symbols and pictograms can be considered as an effective
means for improving customer performance in the world-wide
telecommunication services by facilitating the access to these services
and by simplifying their use;

(b) that investigations during earlier study periods have led to the
standardization of symbols and pictograms for various fields of
application;

(c) that technological developments, especially ISDN, are leading to
new equipment and new services, both for voice and non-voice
applications, for which symbolic representations might be helpful;

(d) that international standardization organizations other than CCITT
are engaged in the development of symbols that may be encountered in
a telecommunications environment;

(e) that agreements regarding harmonization of the layout of numeric
keypads, which were reached with ISO and IEC during the study period
1985-1988, require continuing liaison with these bodies;

(f) that there is a growing need for an internationally standardized
system of signs to direct users to public telecommunication facilities
and to indicate types of services and the means of payment accepted;

(g) that there is a growing need for an internationally standardized
system of symbols and pictograms to instruct users of new types of
public payphones, particularly cardphones,

the following Questions should be answered

1. How can pictograms and symbols be used in instructional material,
directories, user guides, etc?

2. What guidelines should be adhered to when two or more symbols or
pictograms are combined to convey a single meaning?

3. What symbols may be used for new equipment and services both for
voice and non-voice applications?

4. What continuing studies and consultations with ISO and IEC are
needed to promote standardization of layout of keypads for numeric
and function keys?

5. What symbols or pictograms are needed to direct users to public
telephone facilities and to indicate the types of services and the means
of payment accepted?

6. What pictographic instructions should be recommended for use on
or near payphones, especially cardphones. This activity will require
close collaboration with Question 31/I (Question 12/II in the 1985-1988
period)?

7. What symbols and pictograms are needed to assist the handicapped
in the use of telecommunication services?

8. What other activities are needed to maintain and improve Recom-
