The US Architectural & Transportation Barriers Compliance Board (ATBCB) or "Access Board" oversees the Americans with Disabilities Act and related matters such as compliance issues, clarification etc., The following compilation of material was taken from publicly available information at the Access Board Website.
The following information, taken from Access Currents - Current News from the U.S. Access Board (Volume 3, No. 5 September/October 1997) summarizes the current position of this document in the legislative process:
ADAAG REVISION
OVERVIEW: In 1994, the Board established a 22-member ADAAG Review Advisory Committee to review and make recommendations for updating ADAAG to ensure that it remains consistent with technological developments and changes in model codes and national standards, and continues to meet the needs of people with disabilities. The committee developed a comprehensive set of recommendations for changes to sections 1-10 of ADAAG and presented its recommendations to the Board in July 1996.
STATUS: The Board has agreed to a process for this rulemaking and voted on revised text of ADAAG at its September Board meeting.
NEXT STEPS: The Board intends to publish a notice of proposed rulemaking (NPRM) in Spring 1998 and hold at least two public hearings to receive feedback during the comment period.
The ADAAG is in the process of revision by the Access Board:
"The Board has approved revisions to ADAAG and will complete action on the other parts of this rule in the coming months. A proposed rule is scheduled to be approved by the Board at either its July or September [1998] meeting. A public comment period of 90 or 120 days will follow publication in the Federal Register. The Board plans to hold at least two hearings across the country on the proposed rule during the comment period" (Access Currents Vol. 4 #2, Mar/Apr 1998).
In this compilation the full Table of contents of the original document is supplied. Each marked section in the table of contents relates to ATMs, Kiosks, and ITMs.
The full text of each of those underlined sections is given.
Note: the "Recommendations for a new ADAAG" does not include any explanatory text, appendices, or figures).
In late 1996, the ADAAG Review Federal Advisory Committee released its Final Report, entitled "Recommendations for a new ADAAG". This will be voted on by the Access Board early next year. The text given at the top of each page of the printed version of that report states:
NOTE: This report is a set of recommendations from the advisory committee to the US Access Board. Any proposed revisions to the ADAAG will be made through the federal rulemaking process. This report is not part of any rulemaking.
The material is a copy of that available at the Access-Board website, and therefore any caveats that the access board makes relating to its information applies here also. This compilation should not be taken as the letter of the original document, since errors or omissions may be present, either caused during the compilation, or inherent in the Access Board’s source. While every effort has been made to compile this information in as thorough a manner as possible, the Trace Center makes no claim that all possible sections of the Recommendations for a new ADAAG that pertain to Kiosks and ATMs are included in this compilation. Italicizing and Bold formatting of the original text, for emphasis and titles, may not have been preserved in this compilation.

Recommendations for a New ADAAG
ADAAG Review Advisory Committee
Final Report
September 30, 1996
INTRODUCTION
This report represents the final recommendations of the ADAAG Review Advisory Committee to the US Access Board for revisions to the Americans with Disabilities Act Accessibility Guidelines (ADAAG). This final report is presented in the form of a new set of guidelines.
NOTE: This report is a set of recommendations from the Advisory Committee to the US Access Board. Any proposed revisions to ADAAG will be made through the federal rulemaking process. This report is not part of any rulemaking.
RECOMMENDATIONS FOR FORMAT OF THE NEW ADAAG
In addition to the scoping and technical provisions presented in this report, the Advisory Committee also recommends a new format for the next edition of ADAAG. Recommendations regarding dimensions, defined terms, language style, and numbering are already incorporated in the report; they are specified here for use by the Access Board. This report does not incorporate the Committee recommendations for layout; figures and commentary were not fully addressed by the Committee. Recommendations for layout, figures and commentary are for use by the Access Board in developing the next final ADAAG.
These guidelines provide scoping and technical requirements for accessibility to sites, facilities, buildings, and elements by individuals with disabilities. These requirements are to be applied during the design, construction, and alteration of sites, facilities, buildings, and elements to the extent required by regulations issued by Federal agencies under the Americans with Disabilities Act of 1990.
The technical requirements in these guidelines are based upon adult dimensions and anthropometrics.
Nothing in these guidelines is intended to prevent the use of designs or technologies as alternatives to those prescribed in this document, provided they provide equivalent or superior accessibility and usability.
Dimensions that are not stated as "maximum" or "minimum" are absolute. All dimensions are subject to conventional industry tolerances.
