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

Functionality Testing Results (Contd)
• OCR engine produces near ideal results for high quality images
• Probable poor OCR results are due to noise, colored background or distractions
• OCR performance was greatly improved by applying image pre-processing techniques
What we understood from the test result
What we did to improve the performance
Functionality Improvement / Phone Device
Employing Phone’s Camera in Phone Reader
Improving the User Interface (Buttons,Options)
Usability Testing
Questionnaires
• 10 participants
• Task sheet provided
• Feedback analyzed

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
• We tried to simplify the process of image capturing by eliminating unnecessary option buttons
What we did to improve the performance
User Manual
• Run the application
• Capture an Image
• Press OCR button
• Press TTS button
