People without disabilities could experience accessibility barriers when they use chats in mobile devices due to the mobile limitations. Thus, this study takes into account users without disabilities in order to know their experiences and problems when they use chats in mobile devices and desktop computers.


In order to know the barriers that people face when they use chats, three different HCI methods were combined: personas and scenarios; and questionnaires. The first one aimed to obtain the main challenges that people without disabilities, who use chats in mobile devices for learning environments, could face. To do it, fictitious personas were created. Later, they were combined with the developed scenarios. Through this study, it was detected that people without disabilities could experience troubles due to the limitations of mobile devices. Finally, it was generated a questionnaire which was spread through forums and email lists.


People could face many barriers when they use chats in mobile devices. These devices have many restrictions, which could provoke accessibility challenges. Some of them are related to: the small keyboard, the small screen, the use of these devices in environments such as: sunny places or in the move and so on. The resources showed in the Output section some of the accessibility problems that people face. However, a complete list of them has not been published yet.
