Project Page

The Project Pages were created in an effort to help promote student projects. The Project Pages provide a showcase where employers, other students, and friends can see what UIUC students are capable of. Many employers, in particular, consider a good Senior Design Project to be just as valuable as internship experience. The Project Pages will develop over time into a valuable library of practical engineering knowledge. Some of the best projects will be identified each semester and placed in the Senior Design "Hall of Fame," while the rest will be accessible by semester and search engine.

Updating Project Information

Once your project has been approved on the discussion board by the Instructor, you should promptly update your project information. In order to do so, find your project on the Project page, and click its title. When a frame expands, click on "Edit." Next, enter your UIUC netid and password. The system will lookup your project and prompt you for information such as your project's title. Please fill in the information that you wish to have appear for your project, and then click on the submit button. The required fields are marked so. You can update this information at any time. We strongly urge you to keep a backup of all of the information, and we would like to caution you of one scenario in particular. If multiple people attempt to edit this information at the same time, the second person to submit the changes will overwrite the first person's changes. Also, be sure to logout when you are done by closing the web browser. It is important that you provide a project desciption. It should be a brief overview of your project and explanation of why it is worth doing. Please provide this information as soon as possible and try to limit the length to about 250 words.

Submit Schedule

After updating your project information, you should proceed to the Submit Schedule page. Here each student should submit his/her schedule so that your TA can schedule a weekly meeting time. We know that there are a lot of boxes to check, but we need this detailed information because of how difficult it is to match schedules. The information is displayed in a convenient way for TAs when it is time for them to schedule meeting times. The system is very intuitive so instructions are not needed. NOTE: Please be sure that the schedule you submit is as accurate as possible, since you won't be able to edit it later!

After submitting your schedule, you should familiarize yourself with the "Upload Files" page.

Uploading Files

This area is used to upload files such as the Proposal, the Final Paper, Images, and additional files. When a file is uploaded, it is renamed and limited to a specified size. Special documents such as Proposals and Final Papers should be uploaded into the appropriate slot and will automatically be added to your Project Page. Images and other files can be uploaded into any other slot such as "file1." To upload a file, simply select which slot to place it in, and then select the file from your computer using the "Browse" button.

Backpack Buddy - Wearable Proximity/Incident Detection for Nighttime Safety

Featured Project

# Backpack Buddy

Team Members:

- Student 1 (cuasay2)

- Student 2 (rkajjam2)

- Student 3 (eegrob2)

# Problem

The UIUC campus is relatively a safe place. We have emergency buttons throughout campus and security personnel available regularly. However, crime still occurs and affects students walking alone, especially at night. Staying up late at night working in a classroom or other building can lead to a long scary walk home. Especially when the weather is colder, the streets are generally less populated and walking home at night can feel more dangerous due to the isolation.

# Solution

A wearable system that uses night vision camera sensor and machine learning/intelligence image processing techniques to detect pedestrians approaching the user at an abnormal speed or angle that may be out of sight. The system would vibrate to alert them to look around and check their surroundings.

# Solution Components

## Subsystem 1 - Processing

Processing

Broadcom BCM2711 SoC with a 64-bit quad-core ARM Cortex-A72 processor or potentially an internal microprocessor such as the LPC15xx series for image processing and voltage step-down to various sensors and actuators

## Subsystem 2 - Power

Power

Converts external battery power to required voltage demands of on-system chips

## Subsystem 3 - Sensors

Sensors

Camera - Night Vision Camera Adjustable-Focus Module 5MP OV5647 to detect objects in the dark

Proximity sensor - detects obstacle distance before turning camera on, potentially ultrasonic or passive infrared sensors such as the HC-SR04

Haptic feedback - Vibrating Mini Motor Disc [ADA1201] to alert user something was identified

# Criterion For Success

The Backpack Buddy will provide an image based solution for identifying any imposing figure within the user's blind spots to help ensure the safety of our user. Our solution is unique as there currently no wearable visual monitoring solutions for night-time safety.

Potentially: GNSS for location tracking, light sensor for outdoors identification, and heartbeat for user stress levels
