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.
Claims20
A touch device warning method for a touch device, the touch device being in wireless communication with a touch pen, the touch device warning method comprising steps of:
- judging whether the touch device is triggered by the touch pen;
- if the touch device is not triggered by the touch pen, judging whether the touch device is moved;
- and
- if the touch device is moved, issuing a warning signal.
A touch device warning method for a touch device, the touch device being in wireless communication with a touch pen, the touch device warning method comprising steps of:
- judging whether the touch pen is in a proximity range of the touch device;
- if the touch pen is not in the proximity range of the touch device, judging whether the touch device is moved;
- and
- if the touch device is moved, issuing a warning signal.
A touch device warning system, comprising:
- a touch pen;
- a touch device in wireless communication with the touch pen, wherein when the touch device is triggered by the touch pen, the touch device generates an operation signal, wherein the touch device comprises:
- a tilt sensor disposed within the touch device for detecting a tilt status of the touch device;
- a warning unit for issuing a warning signal;
- and
- a controlling unit connected with the tilt sensor and the warning unit, wherein according to an operation status of the touch screen triggered by the touch pen and the tilt status of the touch device detected by the tilt sensor, the controlling unit determines whether the warning signal is outputted or not.
