There exists an inconsistency to signalling for personal transportation. For bicycles there are the common arm signals which many riders do not use and many drivers may not recognize. For other modes of transportation such as skateboards and scooters there is no standard. There exist solutions both wearble and bike attached that allow for light based signalling more akin to a motor vehicle. However, many don’t use movement to change signal modes and those that do attach to a bicycle making them impractical for other modes of transportation.

We propose using a 9DOF Inertial Measurement Unit integrated on the lower back of a vest with built in lighting. It would be used to track rider movements in 3D space and in combination with manual button controls, this would make signalling more akin to a motor vehicle. Controlling the system would be a low power microcontroller and the vest would be powered by a rechargeable LiPoly battery and would all at a price comparable to existing solutions wearable signal systems (~50 $USD).

Unique Features of Note:
1. The automation of turning off turn signals using rider motion as well as braking
2. Forward illumination on the chest, to be street legal at night
3. 360 visibility in the form of RGB LED strips that go around the shoulders and back of the vest
4. A High visibility “Crash Mode” to keep the rider visible in case of an accident
5. Riding modes for other forms of personal transport such as skateboards (both footedness supported), scooters, and rollerskates.

Stretch/Bonus Goals:
1. Bluetooth connectivity to a smartphone.
2. Integration of a sound signal.
3. User customization such as different light patterns so groups can easily differentiate between each other at night.

Problem:

The Donor Wall on the southwest side of first floor in ECEB is to celebrate and appreciate everyone who helped and donated for ECEB.

However, because of poor lighting and color contrast between the copper and the wall behind, donor names are not noticed as much as they should, especially after sunset.

Solution Overview:

Here is the image of the Donor Wall:

We are going to design and implement a dynamic and interactive illuminating system for the Donor Wall by installing LEDs on the background. LEDs can be placed behind the names to softly illuminate each name. LEDs can also fill in the transparent gaps in the “circuit board” to allow for interaction and dynamic animation.

And our project’s system would contain 2 basic modes:

Default mode: When there is nobody near the Donor Wall, the names are softly illuminated from the back of each name block.

Moving mode: When sensors detect any stimulation such as a person walking nearby, the LEDs are controlled to animate “current” or “pulses” flowing through the “circuit board” into name boards.

Depending on the progress of our project, we have some additional modes:

Pressing mode: When someone is physically pressing on a name block, detected by pressure sensors, the LEDs are controlled to

animate scattering of outgoing light, just as if a wave or light is emitted from that name block.

Solution Components:

Sensor Subsystem:

IR sensors (PIR modules or IR LEDs with phototransistor) or ultrasonic sensors to detect presence and proximity of people in front of the Donor Wall.

Pressure sensors to detect if someone is pressing on a block.

Lighting Subsystem:

A lot of LEDs is needed to be installed on the PCBs to be our lighting subsystem. These are hidden as much as possible so that people focus on the names instead of the LEDs.

Controlling Subsystem:

The main part of the system is the controlling unit. We plan to use a microprocessor to process the signal from those sensors and send signal to LEDs. And because the system has different modes, switching between them correctly is also important for the project.

Power Subsystem:

AC (Wall outlet; 120V, 60Hz) to DC (acceptable DC voltage and current applicable for our circuit design) power adapter or possible AC-DC converter circuit

Criterion for success:

Whole system should work correctly in each mode and switch between different modes correctly. The names should be highlighted in a comfortable and aesthetically pleasing way. Our project is acceptable for senior design because it contains both hardware and software parts dealing with signal processing, power, control, and circuit design with sensors.
