Quality assurance impacts the user experience: when things don't work,
users question their understanding and develop superstitions and

** Overly Tabletized Museum Info
Just back from Singapore. It=E2=80=99s about 15 years since my last visit
and it=E2=80=99s amazing how much progress they have made.
The world=E2=80=99s most efficient country.
The new National Museum of Singapore is very impressive,
in terms of both buildings and collections. I particularly liked the
full-length paintings of old-time governors, including one by
John Singer Sargent that could be in any art museum in the world,
even disregarding the historical value.
Sadly, the museum is an example of mobile technology run amok.
All information about the exhibited objects is provided on a tablet
that you borrow when entering the history exhibition.
The good news is that this allows for more in-depth information
than traditional museum labels, and it=E2=80=99s also easier to provide
the text in multiple languages that would crowd a printed label.
But the tablet fails to support the actual museum-going experience.
You pause by a wall or display case with maybe 10-20 objects,
each only marked by a number.
And then you=E2=80=99re supposed to enter all these numbers into the table=
t
to find out what you=E2=80=99re seeing. No way: much too slow.
Nothing beats the roaming human eye in terms of quickly
taking in volumes of information, especially when glancing
around a large physical space. In a second or two, you
can scan a big wall and focus on the label for the object that
interests you the most. A few more seconds suffice to scan the
label for the most pertinent information (what is it? how old is it?),
and then you can either read more or move your gaze to the
next object. All in much less time than it takes to type in a
3-4 digit number on a tablet.
You can easily imagine a more efficient retrieval user interface:
for example one that utilizes location and direction to display
information about an object simply by being pointed in the
direction of that object. While faster, this would still be slower
than simply glancing at a label next to the object.
Let=E2=80=99s stick to old technology when it works better.
Then for sure use tablets to provide supplementary information,
multimedia, and other elements that utilize its strengths and
provide sufficient added-value to justify the interaction cost.
