A heart rate monitor helps the user maintain the target range of physical exertion for maximum benefit. According to experts, visual heart rate display are often distracting and uncomfortable. In this paper, we present the results of a less intrusive approach where heart rate zones are encoded with continuous vibro-tactile feedback. In a participatory design study, we obtained designs for tactile heart rate displays, and in a user study with 16 participants we evaluated one design in comparison to a common design. In a second study with 20 participants, we showed that users are able to assess and maintain their optimal heart rate significantly better using our design.} @COMMENTBibtex file generated on
