The document describes a mobile phone designed for blind users. It uses Braille and gesture-based inputs to allow blind people to make calls, send texts, and access other phone features independently. The phone was tested over multiple sessions, with results showing the gesture-based "NavTap" input method resulted in fewer errors and faster text entry speeds compared to the traditional Braille "MultiTap" method. The goal is to improve the mobile experiences and independence of blind users through accessible technology innovations.
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
