Project Details

Heartless Ninja is a new take on biometric wearables, by tracking the weight of an entire body at the soles of your feet. We combined a few of the wearable technologies available through the LilyPad Arduino for detection, and after jumping through a few communication hoops, present to our users through the Pebble Watch. Three Force Sensitive Resistors (FSR) are positioned to highlight common foot pain points. Web logisitics are able to interrupt the data and push the calculated values onto a Android Service. This android service, with Bluetooth capabilities, has the ability to transmit the resistance values from the FSRs to the PebbleWatch.

Our goal is to create a game environment where challengers to travel to the desired destination with being 'light on their feet'. Everyone, but especially highly athletic professionals could use this game as a training tool as well.
