Abstract
A touch pen, a control method thereof, a touch device, a readable storage medium are provided. The touch pen includes a pen body, a controller, a detecting part, an accommodation part. The controller, the detecting part, the accommodation part are on the pen body. The detecting part has a current detecting circuit, there is a conductive fluid in the accommodation part, the accommodation part is connected to the detecting part; at least a part of the current detecting circuit is inside the detecting part, and configured to contact the conductive fluid and form a circuit with the conductive fluid when the pen body is in a tilt posture, and output a corresponding reference value according to magnitude of a current in the circuit. The controller is electrically connected to the current detecting circuit and configured to output a control signal according to the reference value.
