This document discusses a technology enhanced interaction framework (TEIF) for improving accessibility at a museum. It outlines the current situation where a hearing impaired visitor, Chuty, has difficulty hearing the tour guide Suchat explain the history in areas with background noise or poor lighting. The TEIF methodology is presented as a way to understand interaction contexts and suggest technology solutions. It evaluates options like using phone messages or captions to assist Chuty based on the scenario's requirements, such as the indoor setting and need for a low-cost solution.

Requirement Questions
3. What main role do people have in the
scenario?
a. presenter - audience (the presenter
gives information to the "audience"
which could be only one person or many
people and so controls the interaction.
The audience can ask the presenter
questions).
b. peer - peer (any person can give
information or ask questions to any
other person and therefore no one
person controls interaction)
c. no communication between people
only interaction with technology or
objects
9. What kind of disability does the
audience have?
a.hearing impaired
b.visually impaired
c.physically impaired
d.none
16. Where does the situation take
place?
a.indoors
b.outdoors
c. I don't know
18. Does the customer require a low
cost solution?
a. yes
b. no

Technology Suggestions Table Scores show:
•Suchat using phone to send message to vibrate visitors’ phones
when conversation starts is better than turning lights on and off
in sunlight.
•Controlling pre-prepared captions is solution of choice as Suchat
already knows what he plans to say and Thai speech recognition
not accurate for spontaneous speech
•For information not pre-prepared about exhibits QR codes
simple, cheap, quick and work with smartphones using free
software to provide a link to information on a mobile website.
