Summary: This paper reintroduces pen plotting to interaction and visualization design
through the project of HeartPlotter. The HeartPlotter collects the user's
heartbeat data, maps the data into the pen movements, then presents the
real-time variations in heart rate through its mechanical movements and sounds,
and finally delivers the overall HRV information in a compact form as one
drawing on paper. In this pilot study, we experimented with three basic
mappings between data and visualizations by controlling the pen movement in
speed, path and pen-down timing. The results show that the pen's speed could
present changing heart rate data in real-time and the pen's path mainly affects
the data visualization and the aesthetic of the plotted drawings. Finally, we
discuss the possibility and limitations of the pen plotter used in information
display and interaction design.

Summary: Heart Calligraphy is a biofeedback installation that creates abstract
portraits of participants with their heartbeat data using a pen plotter. The
real-time heart rate is mapped to the basic parameters of the pen's behaviors,
namely speed, position, pressure and pen-down time. Due to the natural
variability in heart rate, every portrait becomes personal and unique graphic,
which reflects the natural biorhythm inside human body. The installation
explores the role of the body as a channel through which physiology manifests
itself in a form of beauty.
