Editor’s note: There are 2 parts in this post: first I am going to give a brief introduction of  the game of Wason’s Card, second I will conclude how the game of Wason’s Card can improve our design of an interface.

In the designing of a new interface, it is good to use metaphors to put it into the design. Because the user has  previous experience of using the metaphors, metaphors will help the user to get to learn to use the new interface faster without to learn it in details.

In this post, I would like to record about the “Think Aloud Method” which I learn from human computer interaction HCI.
