ALEXANDRIA, VA. -- Technology that
enhances the way
we interact with
professional broadcast
products has greatly
evolved over the past
decade and nowhere is
that more evident than
in the increasing presence—
nearing ubiquity—
of the touchscreen.
Touchscreens are nothing new to our
business, but recent product introductions
have illustrated how far the technology has
come. Perhaps nowhere was this more evident
than in Grass Valley’s recent introduction
of its Director Integrated Nonlinear
Live Production Center (today’s name for
“switchers”). The look of a switcher hasn’t
changed all that much over time but the Director is
one that stands out—a product that takes
advantage of the power and simplicity behind
software-based interfaces. With an iPad-like
touchscreen control surface (along with
traditional switcher buttons and fader bars),
the unit is designed to occupy less space but
provide many of the same powerful features
in a traditional switcher.
Software platforms are increasingly oriented
to the touchscreen, including the
most popular platform, Microsoft, which
optmized Windows 8 for such devices. But
the discrepancies between how the software
works for the latest devices and what
works for legacy hardware can sometimes
be glaring. Bill Hayes, director of engineering
for Iowa Public Television, discovered
this when he expounded on the increasing
use of touchscreens in production switchers
recently in “Digital Journal,” and talked about
the confl ict between the user interface and
the underlying technology. Referring to the
new version of Windows, Bill said “anyone
who has installed software in the default
mode quickly recognizes that the favored
user interface is a touchscreen on a tablet,
not a keyboard and a mouse.” Bill added that
there is, in some ways, a “mismatch” between
the software and the traditional interface.
What’s driving the increasing use of
touchscreens in our industry is also what
is driving its popularity in consumer
products—simplicity and flexibility. The
ability to use software to assign multiple
processes allows us to forego the more
intensive training that was involved in
the past and promotes customization—all
within a smaller footprint. And more of us
are replacing traditional hardware tools
with consumer touchscreens like Android
smartphones or iPads, equipped with apps
that allow us to monitor, manage and move
content on a daily basis.
Some manufacturers are looking beyond
the touchscreen and towards hand
gestures. Nobody is suggesting that we
are anywhere near a “Minority Report”-
type scenario, where directors use such
gestures in thin air to direct a production;
most of these incremental changes start in
lower market products (Grass is marketing
the Director to small and mid-market facilities),
before moving to the professional
arena where requirements are more demanding.
For the time being, professional
production will still require hardwarebased
interfaces; however, the increasing
use of the touchscreen as a control surface
means we could see more revolutionary
hardware designs at future NAB Shows.
