Roads are not safe for cyclists. In this report, we discuss the extent of this social challenge and innovative means to counteract cyclist risk. To that end, we consider the following question: How might we increase driver and cyclist awareness in order to improve cyclist safety? To answer this question, we discuss user needs, pain points, and means to enhance cyclist accessories. Through this exploration and human-centered design, we present design research and ideation of a fully integrated, wearable device that senses approaching cars via sonar sensors, vibrates to warn the user, and flashes LED lights to warn drivers.
