FUTURE PLANS
Ideal Design Implementation Explanation
The iBike system was designed to leverage existing capabilities of smart phones so that it would be simplier (and cheaper!) for end users to buy. However, the flip side of this is that it requires users to own a smartphone in order to use the system. Our system uses a native application to access the phone's GPS system and communicate with the Bluetooth module on the gloves.
The Bluetooth module operates as a serial port sending information between the phone and the microcontroller. The phone outputs a signal to indicate whether a left turn or a right turn will be coming up. Then, the microcontroller powers the vibrate motor on the appropriate glove. The electrodes on the wrist strap output a signal to the microcontroller, which calculates the heart rate and then sends that back to the phone to store.
The turn signals within the system are self-sufficient, and can operate without the use of a phone. The levers complete a circuit to activate a LED.
Although it wasn't designed for it, this system could be used for purposes other than bike riding. A user could wear the gloves while doing any aerobic activity, like jogging, and still capture the heart-rate information. Furthermore, the gloves could be worn while driving (or even placed in one's pockets) for a tangible navigation system that's safer than scrolling through a digital map on a phone.
