Chatting with the help of a colour encoded eye pointing alphabet chart (1)

Tiago and Katharine discuss Christmas presents. Tiago uses an alphabet chart set up so that he can eye point to letters. The letters are organised using colour encoding. Tiago first points with his eyes to the block containing his letter. He then points with his eyes to the coloured dot that matches the colour of the target letter. In this way, he is able to spell out what he wants to say using his eyes.
