Electronic Eye for Visually Impaired Persons

This paper presents an electronic travel aid for blind people to navigate safely and quickly, an obstacle detection system using UVC camera based visual navigation has been considered. The proposed system detects the obstacles up to 300 cm via sonar and sends feedback in form of beep sound to inform the person about its location. In addition to this, an UVC webcam is connected to 32 bit ARM mic...

Clothing Matching for Visually Impaired Persons.

Matching clothes is a challenging task for many blind people. In this paper, we present a proof of concept system to solve this problem. The system consists of 1) a camera connected to a computer to perform pattern and color matching process; 2) speech commands for system control and configuration; and 3) audio feedback to provide matching results for both color and patterns of clothes. This sy...

UML Modeling for Visually-Impaired Persons

Software modeling is generally a collaborative activity and typically involves graphical diagrams. The Unified Modeling Language (UML) is the de facto standard for modeling object-oriented software. It provides notations for modeling a system’s structural information (e.g. databases, sensors, controllers, etc.), and behavior, depicting the functionality of the software. Because UML relies heavi...

A Smartphone-Based Obstacle Sensor for the Visually Impaired

In this paper, we present a real-time obstacle detection system for the mobility improvement for the visually impaired using a handheld Smartphone. Though there are many existing assistants for the visually impaired, there is not a single one that is low cost, ultra-portable, non-intrusive and able to detect the low-height objects on the floor. This paper proposes a system to detect any objects...
