Hi

Did you check the user manual how to use the face recognition?

To launch the face recognition Utility:
Start -> All Programs -> Toshiba -> Utilities -> Face Recognition

Usually the registration screen is displayed for a logged in user whose face has not been registered.
The Management screen is displayed for a logged in user whose face has already been registered.

You should click RUN as Administrator in lower left on the Management screen then and then click Register button. The registration screen is displayed now.
If you wish to practice, click on the Next button in the registration screen .
If you don’t wish to practice, click on Skip button.

Then click Next to start the guide. Then click Next again to start image capturing process. Here you have to adjust the position of your face so that it fits within the face shaped frame.
Once your face has been positioned properly, the recording will commence.
Now start moving you neck down and up. Registration will end after you have repeatedly moved you neck to the left, right down and up.
When this registration succeeds, an message would appear on the screen.
Now click next to finish this procedure.

Good news.
