The provision
of information by mobile technologies has become an integral part of our
everyday life. The idea of compressing information and carrying it around for
immediate satisfaction of one’s information needs didn’t take a long time to
gain users’ appreciation. We no longer use our mobile devices just for calling
and texting. It seems (according to Richard Butterworth) to be their least used
function. We grew quite addicted to mobile technology with its magical power to
connect us to the external world regardless of our location. The decreasing cost of devices paired with
their ever increasing functionality make them a must of our daily routine.
As with all
great things in this life and with technology in particular there are some
limitations that may render users frustrated and dissatisfied. Some issues such
as battery life or the speed and ubiquity of the internet access might be resolved
over time according to Moore’s law, which states that semi-conductive technology
evolves in 18-month cycles. Most likely, the majority of us have already
experienced the fast pace of technology evolution: mobile devices are most
likely to become outdated within six months of purchase. Or on the more
positive side of things, if one hadn’t got the means or opportunity to buy a
first generation smartphone, later on they could buy more sophisticated devices
that performed much more smoothly. However, the inherent problems of mobile
devices such as limited screen and keyboard size are unlikely to be solved in the
foreseeable future.
The main
advantage of mobile devices is their context awareness which allows them to
continuously provide useful information for users. Currently, GP systems
provide 40m scope which is not sufficient for augmented reality, i.e. providing
additional information about objects. The European satellite project Galileo
will provide 1m accuracy, and commercial users could get up to a centimetre
accuracy. The major problem of satellite technology is the interference, since
it relies on a simultaneous signal from three or four satellites, thus clouds,
mountains and buildings can still stand in the way of this multi-million
dollar, miracle-of-science technology.
As opposed
to humans, machines are falling behind in visual recognition. Even though there
is face recognition software for PCs, it doesn’t perform dazzlingly on the
phones. It does better with place recognition, which can come in handy.
Bluetooth transmits
data over short distances up to 10-15 meters. This technology is limited by
privacy issues rather than by its functionality. Very few users would
appreciate being fed information by information fountains coming via Bluetooth;
or seeing personalised billboards when passing by them with Bluetooth on. I
certainly wouldn’t.
Limitations.
Limited
screen size represents a challenge for website designers. They would normally
create a single document which would contain all possible information. CSS will
determine how to process the document in response to requests from different
devices. In case of mobile device only essential information will be displayed;
all fancy graphics and images will be stripped so that the document could fit
within the small screen and download faster.
Keyboard
size might represent an issue, especially if one is getting on. Although there
are some ideas on how to tackle the issue of keyboard size, e.g. keyboards
which could be folded or rolled and carried in one’s pocket could be fun albeit
tricky to use, but currently people still find them not as good as they’d wish
them to be. Hence, auto-correction and auto-completion are built-in, but whether
anyone uses them or not is beyond the scope of this discussion.
In the lab,
we had to design an interface that would satisfy our information needs as DITA
students. I joined Caroline and Brittany in their brainstorming. We came up
with some functions that we thought would be useful in the mobile information
context. The idea was to complement the bits we thought were missing on Moodle
for more efficient and comprehensive studying. Brittany even made a fancy
drawing, so you can have a look on her blog. I will limit myself to a concise
list of our ideas.
We bore in
mind that it would be a complementary mobile phone interface; by no means did
we intend to replace Moodle. It’s too complicated.
1) Lectures in two different formats:
pdf and podcast (we loved the idea to listen again to the lecture to comprehend
the material presented after a lab session or after we’ve done some reading).
2) Exercises in two formats: pdf and
visual aids, i.e. screenshots of the steps we are to take, some prompts on how
we could take it further. Half of us are usually wasting time struggling to
understand how to do them. We could use this time for actual learning.
3) Events – curriculum: lecture dates
and times; and relevant events, conferences, seminars related to the course. It
is really tiring to click through dozens of buttons back and forth trying to
find things.
4) Newsfeed/ Discussion boards feed. We’d
love to be alerted when there are new posts and we would appreciate retrieving
them better than we can do now.
5) Blog or as Brittany suggested “Ask
Andy” button.
