  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
