  • Hi my name is Daniel and I come from the Technical University of Lisbon and I am here to present the results achieved in a long term study of our prototype with blind users.
  • Particularly, text-based services have grown a lot as they are cheaper and do not require immediate attention
  • Not all have the opportunity to do so...
  • Particularly blind users are deprived of that visual feedback
  • Excluded from regular mobile interaction
  • This fact called our attention.... And we focused on text-entry tasks
  • They have to recognize the keys and dance around the keypad
  • They have to recognize the keys and dance around the keypad
  • That have different implications
  • Looking back to quesitoning if screen readers can replace visual feedback. What about the keyboatd?
  • And stepped a little bit back and tried to provide a simpler approach with less cognitive and sensory requirements
  • Taxa de erros (ter que apagar uma letra) muito elevada no MultiTap ao contrario dos restantes
  • Overall Several messages were sent but also relevant is the number of messages received. It is important to notice that before NavTap, these users did not send nor receive messages as they rejected any kind of assistive technology. This suggests that a step forward has been given regarding their social interaction
  • How it influences the user’s daily lifes?
