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(More)
