Abstract: A passive touch pen for a capacitive touch screen is provided. The passive touch pen includes a first pen tube, a second pen tube, a fixing post, a conductive pen tip, a circuit board, and a conductive element. The first pen tube is made of a conductive material. The second pen tube is made of a nonconductive material. The conductive element is connected with a negative trace of the circuit board and contacted with the first pen tube. Consequently, the electric energy of the human body is transmitted to the conductive pen tip through the conductive element. Moreover, a negative electrode part is electrically connected with the negative trace of the circuit board through the first pen tube and the conductive element. Consequently, the complexity of the fabricating process and the fabricating cost are reduced.

Abstract: A touch device warning method and a touch device warning system are provided. The touch device warning method provides multiple judgment mechanisms. The multiple judgment mechanisms include the mechanism of judging whether a touch device is triggered by a touch pen, the mechanism of judging whether the touch device is moved and the mechanism of judging whether an untouched time period of the touch pen and the touch device exceeds a predetermined time. Once the conditions of the judgment mechanisms are satisfied, the touch device warning method warns the user of taking back the touch pen. Consequently, the possibility of losing the touch pen is reduced, and the occurrence of the erroneous judgment is avoided.
