Future of Commuting: Final Prototype (Slide Down to Explore)
"Cross-Sensory Parking Assist System:" Our first small project to solve the problem of difficulty of vision during parking
Design Description: Cross-sensory Solutions: As the sensors are around the car detect close around the vehicle, a vibration +audio signal will appear to remind the driver. Vibration motors can be installed on the driver's seat. This prototype will provide tactical feedback, which increases the interaction between the car and the user.
Sketches and models for the first design iteration
Design Rendering: Design idea: Our design features ultrasonic proximity detectors to measure the distances to nearby objects visa sensor located in the front and/or rear bumper. The system in turn warns the driver with acoustic tones, the frequency indicating object tones, the frequency indicating object distance, with faster tones indicating closer proximity and an contious tone indicating a minimal pre-defined distance.

"Lane Change Detector:" Our second small project to solve the problem of difficulty making judgement to change lane due to visual difficulties.
Cross-sensory Solutions: If the distance sensor detects a vehicle is approaching from the back WHILE the driver is making a lane change (the turning signal is on), the vibration motors behind the steering wheel will vibrate. If a car is detected on the left, the vibration motor on the left of the steering wheel will vibrate/speaker on the left will make a sound; If a car is detected on the right, the vibration motor on the right of the steering wheel will vibrate/speaker on the right will make a sound. This prototype will provide tactical feedback, which strengthens the interaction between the car and the user in dangerous situations.
First Design iteration model image: vibration motors are attached behind the steering wheel
Design Idea: Vehicle-based sensor device that detects other vehicles located on the driver's side and rear. Warnings will be visual, audible, and vibrating. Blind spot monitors monitor the sides and rear of the vehicle. They also include "Rear Cross Traffic Alert"
Rear view monitor on the vehicle's rear view mirror.
Signal from monitor then transferred to Arduino, and the procced vibration signal will be transferred to vibration motors behind the steering wheel.
The monitor is covered with a plastic cover, and installed on the mirror.
"Find My Car system:" Our third small project to solve the problem of difficulty of finding a car in a noisy environment with low visibility.
A car remote key with a vibration motor. Based on Radio & Compass signals, the key will vibrate and blink the LED if facing the direction of the car. This function will translate direction information to tactical & visual signals to the users. Therefore, it can make users easier to find the car. Users can hold the remote car key and use it to find the approximate distance from their vehicle.

Design Idea: Real time Single trackers for cars provide instantaneous location data. In the parking lot, the remote can locate the vehicle form a specific area.
