creating the Digital future:
The Role of interactive systems
Dan Olsen, Jr., Brigham Young University
The creation of a new interactive platform is the creation of a
medium for expression. It empowers others to create and deliver
value in ways that once were too difficult, too inconvenient or too
expensive. The introduction of a new interactive platform changes
what is feasible and possible. As we consider research into future
interactive systems, what are the lessons we can learn from past
success. How will we invent the next medium for interactive
expression?
About Dan Olsen Jr.: Dan Olsen Jr. is a Professor of Computer
Science at Brigham Young University and was the first director of
the CMU Human-Computer Interaction Institute at CMU. He is
one of the earliest and most influential researchers in the user
interface software domain. His first contributions were in using
formal language techniques (such as finite state machines and
Backus-Naur Form) to specify the syntactic structure of a user
interface. He has published three books on user interface
software: “Building Interactive Systems: Principles for Human-
Computer Interaction,” “Developing User Interfaces,” and “User
Interface Management Systems: Models and Algorithms.” His
1988 MIKE system was an early and influential system for
automatically generating a user interface from semantic
specifications. Dan has continued to make important research
contributions and novel systems in a wide variety of areas, from
CSCW to Interactive Machine Learning, and developing Metrics
and Principles for Human-Robot Interaction. Dan has also received
CHI’s Lifetime Service Award for his many years of service on
behalf of the SIGCHI community. He was the founding editor of
TOCHI, and played a key role in establishing the UIST conference
and in making it one of the most successful SIGCHI conferences.

PAPeR | observational and experimental
investigation of Typing Behaviour using virtual %
Keyboards for mobile Devices
Niels Henze, University of Oldenburg, Germany
Enrico Rukzio, University of Duisburg-Essen, Germany
Susanne Boll, University of Oldenburg, Germany
Observed the typing behaviour of a large number of smartphone
users using a mobile game and conducted a large-scale experiment
that shows how to improve users’ typing performance without costs.
PAPeR | multidimensional Pareto optimization of
Touchscreen Keyboards for speed, familiarity &
and improved spell checking
Mark Dunlop, John Levine, University of Strathclyde, UK
Describes a new approach to keyboard layout optimization for faster
text entry with better spell correction on touchscreen phones, while
retaining familiarity with Qwerty. Includes designs and user test results.
noTe | Beyond QWeRTy: Augmenting Touch
screen Keyboards with multi-Touch Gestures &
for non-Alphanumeric input
Leah Findlater, Ben Lee, Jacob Wobbrock, University of
Washington, USA
We introduce a bimanual, multi-touch gestural approach for nonalphanumeric
text input on touch-screen keyboards. This
technique is designed to augment, not replace, existing solutions.
noTe | Touch Typing using Thumbs: understanding the
effect of mobility and hand Posture
Hugo Nicolau, Joaquim Jorge, INESC-ID, Portugal
Presents a user study of touch typing whilst walking and the effect
of different hand postures and target size. Can assist designers in
developing new effective mobile keyboards.
PAPeR | WalkType: using Accelerometer Data to
Accomodate situational impairments in mobile &
Touch screen Text entry
Mayank Goel, University of Washington, USA
Leah Findlater, University of Maryland, USA
Jacob Wobbrock, University of Washington, USA
Describes an adaptive text entry system that leverages the mobile
device’s accelerometer to compensate for extraneous movement
while walking. This technique can significantly improve typing
speed and accuracy.
