5. The industrial manipulating method of claim 1, further comprises:
calculating a time length that the current operator stays in front of the computer after determining the photograph contains the face image of the current operator; and
determining whether the time length reaches a predetermined time value.
6. The industrial manipulating method of claim 5, further comprising:
designating the computer as a target computer if the time length reaches a predetermined time value.
7. The industrial manipulating method of claim 5, further comprises:
detecting an external pressure imposed on an input assembly after determining that the time length reaches the predetermined time value; and
determining whether the external pressure is greater than or equal to a predetermined pressure value.
8. The industrial manipulating method of claim 5, wherein the designating the computer as a target computer is implemented if the external pressure is greater than or equal to a predetermined pressure value.
9. The industrial manipulating method of claim 1, wherein the obtaining a photograph of a current operator comprises:
activating a camera embedded in a display; and
controlling the camera to take a photograph on a face of the current operator.
10. An industrial manipulating system, comprising:
a plurality of computers; and
an input assembly shared by the computers;
