Part 1: Critical Thinking

1.

The Ult
imate Style

As mobile devices continue to evolve, they have become lighter and smaller and we are
beginning

to see a convergence of computing and clothing.

a. What would the ultimate convergent mobile clothing be for you? Is there a limit in
weight, size,

or complexity?

b. Can you imagine uses for technology in fashion that would support better health? Be
t-
ter social relationships? A richer intellectual life?

Students could brainstorm
about
what the ultimate convergent mobile clothing might look
like. They might create a sketch of the item explaining what it looks like, of what material
it would be made, how it
might contain or incorporate

a mobile device, and any other
facts about the clothi
ng.

Students could discuss any uses for technology in fashion that might support better
health. For example, they might come up with an idea for integrating sensors into clot
h-
ing to remind a person with diabetes when his or her blood sugar is rising, or ad
d se
n-
sors to shoes that record the amount of walking done during the day and number of cal
o-
ries burned. Students should also brainstorm ideas about how technology can support
social relationships and intellectual lifestyles.


2.

The Endpoint

We have seen the
direction of evolution of portable devices. What will be the final stage
of development for mobile devices? What will they weigh? Will they be implanted in the
human body?

Student responses will vary, but most students will probably agree that such devices

will
continue to become smaller and lighter. Students may include conjecture about implanted
devices, devices that are microscopic or that utilize nanotechnology, devices that are
ubiquitous and work by scanning brain patterns, or other creative ideas.

Part 2 Critical Thinking

1.

Reinvent Yourself

The arrival of digital information has forced major shifts in several industries, such as
publishing, music recording, and film. How has

each industry reacted? Have they each
found ways to reinvent the products and services they deliver to match the challenge of
the Digital Age? What other industries have had to realign their business models because
of digital information?

Student
responses will vary, but should include a review of the ways new technology has
affected the entertainment industries mentioned. Students may discuss the ability to
quic
k
ly and inexpensively download one song or an entire album, the many options now
availa
ble to watch a movie or television show, and the ability to purchase or borrow e
-
books. Students may also discuss the ways that many independent musicians have been
making and distributing their music without the support and backing of a record comp
a-
ny, th
e growing numbers of would
-
be authors who can now self
-
publish their own work
without benefit of a publisher, and the many Web
-
only programs available via channels
such as YouTube and Hulu. Students may also note the changes that have taken place in
the fi
elds of education, science, medicine, art, and sports.


2.

Too Much Media?

As a manager, what concerns might you have about your employees’ use of corporate
bandwidth to download and view media files? Do you think it would benefit your bus
i-
ness to block certa
in file transfers or certain sites? As a manager, are there concerns you
might have if employees have digital cameras on their smartphones? Would your answers
be different in an academic setting?

Students should understand that bandwidth, or data transfer

rate, is the amount of data
that can be transferred from one point to another in a certain period of time. Students
could engage in a debate about whether a business should block access to sites where
videos and MP3 files can be downloaded, with or withou
t an override. When discussing
bandwidth concerns, students could discuss usage caps employers might utilize to prevent
users from transmitting and receiving so much data that a network could be slowed
down.

Students could consider whether the use of digi
tal cameras on
smart
phones poses a pro
b-
lem in a business setting. Should camera use be prohibited to protect the privacy of e
m-
ployees, employers
,

or clients? Should a policy exist regarding the use of cameras and
other recording device? If a conversation w
as recorded on a phone without prior
knowledge or permission, should a policy exist requiring that the recording be deleted?
How would this policy be enforced? Some H&R Block franchises forbid
smart
phones in
the workplace
to avoid

the appearance of client
privacy being risked due to the camera
capability on the phones.
