NordiCHI´14 conference attendees got hands-on experience
with a number of great new interactive systems. Among the
accepted poster, video, and demo submissions, we selected

the following four prototypes to illustrate the high-quality
design research displayed during the conference, which
was held in Helsinki, Finland, October 26–30, 2014.

1. Presenting Information
on Wrist-Worn

Point-Light Displays

Wearable devices with small form factors create a need for simple displays that present information
through single light spots. What should these displays look like and how should they present information

in daily life? In this work we built a light bracelet to explore this question. It consists of an LED stripe,
which is controlled by Arduino components sewn onto an elastic armlet. In a preliminary user study
we investigated how participants experienced self-designed light patterns in their daily lives. From
the results we derived implications for the design of light patterns on wrist-worn displays.
