The TicTocTrac Watch Measures Perception of Moments

It is one thing to be told the time, it is another thing to be told how one has perceived the time that had just passed by; the TicTocTrac watch does both. It is a unique chronograph that is worn like a typical wristwatch even though its face barely resembles one. In place of hands and other recognizable watch features, the TicTocTrac watch has a black box in the center.

By double-tapping the TicTocTrac watch, a time estimation exercise commences.
Designed by students from Cornell University as an engineering project, the screen lights up and displays a random amount of time for a person to wait. When a person feels they have waited that allotted amount of time, they double-tap the TicTocTrac watch again and it informs them if they overestimated or underestimated the time.
