Phone Reader Project

The Phone Reader project aims to assist blind and illiterate individuals by converting images to text using OCR technology and reading the text using TTS. The project includes design, testing, and implementation on phone devices and servers to enhance the functionality and usability of the application.

  1. Phone Reader Project By: Hossein and HadiShayesteh Supervisor: Mr. James Connan

  2. Introduction Phone Reader • Converting Image to text using OCR • Reading out the text using TTS Potential Users • Intended for Blinds and Illiterates • People dealing with a Foreign Language

  3. Phone Reader Design / Phone Device Generated Audio

  4. Implementation / Phone Device

  5. Implementation / Server

  6. Implementation / Phone Device

  7. Phone Reader Design / Server Gray Scale Server Thresholding OCR engine

  8. Project Testing Functionality Testing • Unit testing • - Server • - Phone Device • Integration Testing Usability Testing • Ease of use • Fulfillment of functionality

  9. Functionality Testing / Server Case 1 : 15 different images captured from screen Case 2 : Noise and color applied to Case 1 images Case 3 : • Case 1 images captured by camera Case 4 : • Case 2 images captured by camera Case 5 : Image preprocessing applied to Case 1 images Case 6 : Image preprocessing applied to Case 2 images Case 7 : Image preprocessing applied to Case 3 images Case 8 : Image preprocessing applied to Case 4 images

  10. Functionality Testing Results 1 : 15 different images captured from screen Noise and color applied to Case 1 images 2 : 3 : • Case 1 images captured by camera 4 : • Case 2 images captured by camera 5 : Image preprocessing applied to Case 1 images 6 : Image preprocessing applied to Case 2 images 7 : Image preprocessing applied to Case 3 images 8 : Image preprocessing applied to Case 4 images

  11. Functionality Testing Results (Contd) What we understood from the test result • OCR engine produces near ideal results for high quality images • Probable poor OCR results are due to noise, colored • background or distractions What we did to improve the performance • OCR performance was greatly improved by applying image pre-processing • techniques

  12. Functionality Improvement / Phone Device Employing Phone’s Camera in Phone Reader Improving the User Interface (Buttons,Options)

  13. Usability Testing Questionnaires • 10 participants • Task sheet provided • Feedback analyzed

  14. Usability Testing Result 1 : Successful completion of all the tasks 2 : How easy was working with Phone Reader 3 : How well buttons were organized 4 : Function of each button was easy to understand Overall impression of the Phone Reader application 5 :

  15. Usability Testing Result (Continued) What we understood from the test result • Phone Reader is fairly easy to use • The most challenging part was working with camera What we did to improve the performance • We tried to simplify the process of image capturing by eliminating • unnecessary option buttons

  16. User Manual • Run the application • Capture an Image • Press OCR button • Press TTS button
