摘要

The method involves inputting a secret keyword or a secret number by viewing on appropriate individual letters and/or numbers of a key board successively. A position of an eye of a user is received by a receiving unit i.e. camera, and an association of the eye position to one letter and/or number is evaluated. The data input is started by a start function that is activated by looking on a point. The number and/or the letter nearest to the eyes are fixed before the receiving unit is switched again.
