1.0 INTRODUCTION OF IHearColors

 

Guide dogs have been around since 1931, shaping and coloring blind people's lives. However, only 2% of blind people and the visually impaired own a guide dog globally. This is because of the financial burden and responsibility of owning a guide dog. Mobility difficulties for people with vision problems can arise from obstacles in their environment, difficulty navigating unfamiliar spaces, and challenges with transportation. To overcome this impediment, we designed IHearColors-a, a guide-dog-inspired device that eliminates the challenges of owning a living animal. IHearColors is a wearable gadget that identifies obstacles, and alerts, and provides safe navigation for the visually impaired.

 

2.0 PROBLEM STATEMENT

 

Based on the research, the number of people who lose vision is predicted to increase by as much as 55% in the next 30 years (Fleck, 2024). 1.1 billion people are facing vision impairment. Vision problems can lead to mobility difficulties because they cannot identify the obstacles even though their muscles and bones are healthy. To solve the mobility issue, therapists started to train dogs and designated them as guide dogs. However, the criteria for guide dogs are strict and only 20,000 guide dogs are currently in service. With the increasing number of patients, it is significant that we need an alternative solution. Thus, this report shows our process of designing an assistive device that can address the shortage of guide dogs by using technology to help people with vision impairment overcome mobility difficulties.

 

3.0 OBJECTIVE

 

• To understand the specific difficulties in mobility faced by individuals with vision impairment.
• To design an assistive device to solve the mobility issues of people with vision impairment.
• To analyze the feedback from individuals who suffer from eye disease regarding the effectiveness and usability of the assistive device.
• To investigate the future improvements of the designed assistive device based on technological advancement.
• To ensure the price of the assistive device is affordable and effective.

 

4.0 LITERATURE REVIEW

 

Case Study
A robotic guide dog was developed by Robotic Club Members from the Lowell Association of Blind. The robot can climb stairs and remain steady on the ground. It can also be programmed to recognize unfamiliar buildings and navigate people to the right places. The youngsters created their robotic guide dog with a mobility cane that can be inserted into the top of the robot and used as a handle by those individuals with disabilities. The robot itself has customized wheels that can climb stairs and curves while staying in position when it is not moving, and it sits low to the ground to maintain stability.
To detect objects, the robot's top sensor uses a laser to generate light waves. It receives light that is reflected off of various surfaces and uses a computer and a small amount of artificial intelligence. A depth-sensing camera (SICK Multi-scan sensor) is added to the robot's setup to enhance object detection. To allow individuals to follow the whereabouts of their loved ones, the students intend to add a GPS device that sends data to the website.
