Tawasol Center Tawasol Center offers services addressing key issues facing the deaf and hard of hearing individuals such as: • Call center • They provide information and referral • Sign language training free courses • They have social media presence (Twitter/Instagram/YouTube) to disseminate sign language videos.
  9. 9. Tawasol App • Insufficient and inadequate support for Arabic-based sign language applications was the motivation for developing Tawasol in cooperation Tawasol Center. We use the TAWASOL center’s created sign language videos to build a mobile application. • Tawasol is a free educational mobile application that is developed in the area of assistive and educational technology to support adults with hearing impairments.
  10. 10. Tawasol: Arabic Sign Language App Tawasol app contains of three main functions: • Dictionary • Tutorial • Finger-spelling
  11. 11. Dictionary Consists of different categories representing Arabic words. Each category contains a number of words. Dictionary features: • Search word • Repeat • Sound control • Favorites
  12. 12. Tutorial As a quiz; a player matches a presented sign language video to the correct word from a list of different words. The user has the ability to customize the quiz by selecting various difficulty levels; number of presented word options 2, 3 or 4.
  13. 13. Finger Spelling The App will take a phrase entered by the user and then display the Sign Language symbol for each letter in the phrase. The user has the ability to control the speed of the spelling.
  14. 14. Design Considerations  portable electronic devices, in this case, tablets and smart phones are more effective than printed material, easier to learn and used at anytime and anywhere.  The interface is designed to adhere to accessibility and usability guidelines, in addition to following Apple’s Human Interface Guidelines  In order to get the advantages of the video-based system over the textimage-based system, the signs’ videos have the following features: – quality – recently created in 2014 – simple background – unified theme – same speed
