A tool to help those with dyslexia, its full title is, The Mystery of the Lost Letters - Tintin helps dyslexic learners.

Designed to raise morale and assist young dyslexics to understand and get to grips with coping with their dyslexia, this trilingual (EN, FR and German) self-help tool invites the user to accompany Tintin on a series of adventures of discovery.
Finally the young user is awarded a certificate of completion, with a profile of his or her learning styles, complete with self-help tips.

The CD-ROM is designed to be used in one-to-one situations with children, and is presented as a series of game-type environments, through which the reader proceeds in a structured fashion.
