| Group: Suriya Kodeswaran - kodeswa2 Larry Liu - lliu65 Kevin Tian - ktian2 Problem: While there is an implied system for cyclists to communicate between people, other cyclists, and cars, there is no universal method and often signs could be misleading. Solution: We propose to have a glove for the cyclist to wear which communicates wirelessly with two arrow lights as well as a break light that is attached to the bar that is attached to the seat. When the cyclist waves the hand to the left or to the right the respective arrow lights up through an accelerometer sensor which will last for 5 seconds. To determine when the user is breaking the sensors on the fingers can detect if the user is pulling on the break. The benefit for this solution is that it allows the cyclist to use one system on multiple bikes easily. Another functionality we are thinking of implementing is that if the cyclist falls we have powerful LED's on the glove to turn on so cars/other people can avoid them. ------ updated summary ------ After talking a TA during office hours, she suggested that we list out a final summary of our proposal. Hopefully this will help outline our overall idea: Our focus on this bike system is to have pressure sensors constructed into a sleeve that would be put onto a portion of both handles. When these sleeve are pressed, LED lights on the back of the bike (under the seat) will be activated via Bluetooth communication. Once the rider has completed his/her turn and is riding in somewhat straight line again, the accelerometers will detect this and turn off the blinking LEDs. In addition to these features, we will utilize ultrasonic and infrared sensors in a small circuit attached to the back of the bike (using some form of strap). We plan to have this more advanced feature to act as a blind spot detector. Using both sensors, we should be able to provide a warning to the rider (via small LEDs on the handlebars) if a vehicle is approaching. The TA suggested we look into the LIDAR module for this task. Also, this will serve as a simple method for warning the rider where it's definitely on the safer side to have false positives (from detection of non-vehicle objects such as trees or fences). |
