|An E-Tran frame is a sheet of stiff, transparent plastic (Perspex) onto which picture, symbols or words can be stuck with Blu-Tack or Velcro. The communication partner faces the user and holds the frame up between them. The user gazes at the picture, letter, symbol, or word they want to choose.|
|Look2Talk is a colour-encoded communication book that is designed for those who eye-point. The user first eye points to the block containing the target symbol, and then clarifies which symbol they want from the block by eye pointing to the coloured dot that matches the border colour of the symbol.|
