Hello Forde and thank you for your question.
The kiosk should be operable by:
- people regardless of their height or stature
- people who are in a wheelchair
http://imperial.park.org/Guests/Trace/pavilion/minimum.htm
The design of the ticket machine with a touch screen interface (kiosk)
that you´re designing must comply with the Americans with
Disabilities Act for ITMs (Information / Transaction Machines: Kiosks,
ATMs etc.)
ITMs (Information/Transaction Machines) includes such things as ATMs,
ticket vending machines, computer kiosks, electronic building
directories, fare machines, etc.
Under the provisions, of the ADA therefore, kiosks and ITMs are
covered in the same way ATMs are.
Clear Floor Space in front of the ITM and Reach
“The ADAAG makes specifications of reach requirements (i.e. where
interface elements can be positioned relative to the ground and the
leading edge of the ITM) in terms of forward (front) approach and
parallel (sideways) approach. Complying with these guidelines is a
straightforward matter of designing components to be within the
specified ranges in an installed ITM.”

Manufacturers and suppliers of ITMs should comply with section 4.34 of
the ADAAG "Automated Teller Machines". The following gives an outline
and commentary of the main provisions of the ADAAG and the
Recommendations for a New ADAAG.

Section 4.34.3 Reach Ranges
“This section deals with the ability of a wheelchair user to reach the
controls of the ATM, without having to reach beyond a comfortable
or safe limit. The ATM owner can choose to comply with either the
forward reach requirements or the side reach requirements. As shown in
the drawing to the right, if approached from the forward position, the
controls and delivery slots must generally be between 15” and 48” from
the floor surface.”
“When approached from the side (the most common approach) the reach
ranges are somewhat wider. This is because the user does not have to
reach out over the front and possibly fall out of the chair.
The range here is between 9”and 54”.

Average dimensional data which will aid you in your calculations:
Dimensional data to a normal person (height, eye and shoulder)
Common reaching zone
Dimensional data of a wheelchair user
Vertical reaching zones of a wheelchair user

Screen position
”Sunlight can degrade the viewability of the display for all users.
The screen should be shielded from direct or reflected sunlight or
other bright light sources. The display should be viewable from the
eye level of a person sitting in a wheelchair. People with low vision
should not be prevented from getting their faces close to the screen.”
There are 3 diagrams illustrating the recommended angles for the
screen according to height here:

Here are universal access features which can be applied to almost any
public or personal electronic device.
