Pointing
Preconceptions
Out
The
design
of
interactive
systems
today
builds
a
lot
upon
previous
system
architectures
and
interaction
paradigms,
and
upon
general
knowledge
about
the
user’s
needs
and
skills.
However,
classical
system
architectures
hide
technical
constraints
in
their
midst
that
we
may
not
even
acknowledge,
and
“what
everybody
knows”
about
user
capabilities
can
turn
out
to
be
false.
In this talk I will present some of my recent and ongoing work on the design, tuning, and engineering of cursor control mechanisms, under the scope of common blind spots and misconceptions in interaction design. I will in particular discuss the consequences of system and human delays, why we consider them inevitable, and what interactive systems would need to address them.
Bio: Mathieu Nancel is a permanent researcher in the Loki research group at Inria Lille since 2016. After defending his Ph.D. in Saclay with Michel Beaudouin-Lafon in 2012, he worked as a postdoctoral fellow with Andy Cockburn in University of Canterbury (Christchurch, NZ), with Dan Vogel and Ed Lank in University of Waterloo (ON), and with Antti Oulasvirta in Aalto University (Helsinki, Finland).
His research interests span interaction technique design, understanding psychomotor phenomena, and the engineering of interactive systems. He works in particular on the ubiquitous task of cursor control, with a focus on fine-grained timing phenomena on both the user and the system sides.

Recognition
or
Recall?
The
Case
of
Expert
Features
in
GUIs
Users
have
many
options
to
enhance
their
productivity
with
applications,
for
instance
by
learning
new
interaction
techniques
to
get
their
work
done
faster.
One
example
of
such
interaction
techniques
are
hotkeys,
which
enable
rapid
execution
of
frequently
used
commands.
However,
“expert”
features
like
hotkeys
are
often
ignored
and
users
stick
to
“novice”
interaction
mechanisms,
limited
by
a
relatively
low
cap
of
performance.
In this talk, I will describe some of my previous work that attempted to foster and facilitate the adoption of these features. I will also present more recent work discussing why we may be expecting too much from the user and how “expert” features could be re-designed to provide similar performance with less effort.
Bio: Sylvain Malacria is a permanent researcher in the Loki research group at Inria Lille. His research in Human-Computer Interaction investigates the design of novel interaction techniques and user interface refinements, with a focus on fostering the transition from novice to expert mode when interacting with systems.
Before joining Inria, Sylvain has worked with Eric Lecolinet at Télécom Paristech on identifying which type of resources (software and hardware) can be used to enrich the input bandwidth, spent two years at the University of Canterburry (New Zealand) working with Andy Cockburn, and one year in the UCL/BBC Lab London.
