RSVP iconCHAT

• Abstract

  Most existing BCI research for assistive communication interfaces focus on the use letters to generate written text. This requires the subjects to be literate and comfortable with typing in general. As an alternative approach, in this project, we seek to design a BCI that enables the user to generate language using an iconic language called iconCHAT developed by Dr. Rupal Patel.

  Most existing BCI research for assistive communication interfaces focus on the use letters to generate written text. This requires the subjects to be literate and comfortable with typing in general. As an alternative approach, in this project, we seek to design a BCI that enables the user to generate language using an iconic language called iconCHAT developed by Dr. Rupal Patel. Expected benefits include increased speed of communication as each icon might represent a word or phrase so equal number of item selection can construct a sentence instead of a word compared to RSVP Keyboard. A potential drawback is the necessity for the subject to become familiar with the icon set; this also means a closed vocabulary language generation system which is suitable for limited context interactions. An option to switch to letters for open vocabulary text generation can be incorporated to the final design for users that prefer to have this option.
