Byeongjun Kim – Nike Baton – Pacemaker

IssuesFor example, assuming that a novice runner gets feedback such as duration and average pace every single kilometer, the following problem happens. Because it’s hard to keep the pace for beginners, the runner tends to speed up to compensate his or her pace when he or she gets the feedback which tells he or she slows down. Consequently, the runner’s pace repeats up and down periodically and he or she will soon get exhausted. Concept – The pacemaker giving feedback by vibration in real-timeNike Baton was designed to solve these issues. It detects runners’ pace and gives feedback with vibration whenever the pace is slower or faster than desired pace in order to help runners keep their pace. Highly inspired by a baton which stands for a connection between ends and starts for runners, Nike Baton helps runners to work out constantly in a right way. Using the dial on top, the target pace can be set before starting running. In addition to the pre-set pace, the ‘Auto’ mode provides personalized target pace by analyzing runners’ work out pattern and history. The heart rate sensor is located on the back side and it perfectly contacts to the runners palm. The sensor detects runners’ heart rate to provide more accurate work out information and calculate calories burnt. The accompanying wireless charging dock displays the running information and history, so that runners can get always motivated. While Baton is placed on the dock, it is automatically synchronized with the Nike+ Run Club App or other health Apps to update the work out data.PrototypingThe concept was prototyped with Arduino and an accelerometer. First, the acceleration data of the movement of arms when running was analyzed. Arduino Pro mini was used to make it smaller after getting the patterns with Arduino Uno. Besides vibration motors, 2 LEDs were used to visualize the feedback. 3D printed parts were modeled to be assembled and they were painted after polishing.
