Spelling With E-TRAN

Low Tech Solutions offers an alphabet-based E-TRAN. This enables an individual to spell using eye movements.

Our E-TRAN is laid out in such a way that the most frequently used letters in the English language (A, E, I, O, M & T) can be selected with a single glance.

It works on the same principle as the ‘Color Coding’. These high frequency letters make up about 44% of the English language. Being able to select the high frequency letters with a single glance can help make spelling faster.
