Call for participants: Medical devices and HCI - full day tutorial in
A Hands-on tutorial on designing safer user interfaces for interactive
medical devices. Case studies and examples will be discussed on reducing
use error and possible solutions to common design issues.
Register for this workshop on the NordiCHI 2014
<http://nordichi2014.org/attending/registration/> website. Early bird
registration prices are available until September 18 and late registration
closes on October 23.
HCI practitioners, interaction and UX designers, software developers and
engineers interested in the design of user interfaces for medical devices.
Theme and goals
This tutorial will focus on data entry, one of the main sources of use
error in healthcare. The data entry systems of commercial medical devices
will be presented, and pros and cons of the different systems will be
The tutorial will highlight:
- Issues surrounding the design of the next generation of user
interfaces based on touch screens, voice feedback and physical computing
- The challenges involved when designing for safety.
- Interest in the medical/healthcare domain and user interface design.
- Some programming experience will be useful, but not essential.
- No previous experience with electronics or hardware is required.
Description of activities planned
Presentations on safer user interface design for medical devices will be
combined with hands-on activities, where participants get the opportunity
to both gain familiarity with existing interfaces and then design their own
A demonstration of medical device user interfaces, reverse-engineered from
existing designs and recreated using software verification techniques, will
be given together with a discussion of some of the issues surrounding these
Novel touch screen-based interface prototypes for number entry will be
available for participants to experiment and play with. The interfaces
benefit from combining output display and input control in the same UI
element, and explore different ways of visualising number and digits within
Hands-on activities also include experimenting with the e-Health Shield, an
expansion board for the Arduino prototyping platform to perform different
kinds of clinical measurements, for example ECG (Electrocardiogram) and
pulse oximetry (SpO2). Participants will explore different ways of
visualising and interacting the - data coming from the sensors with
physical computing widgets, including LED matrices, LCD displays and rotary
wheel encoders. These clinical measurement data can also be visualised on
the touch screen-based interfaces and designed to be easier for
non-clinicians to make sense of the data.
By following a learning by doing approach, supplemented with discussion,
participants will gain a better understanding of the hardware and software
components of a medical device user interface and how to better design
these interfaces for different purposes.
