    Abstract: An active stylus and a detection method thereof are provided. The active stylus includes a first optical distance measurement circuit, a second optical distance measurement circuit and a signal processing circuit. The first optical distance measurement circuit is arranged at/on the side of the active stylus to measure a first distance between the active stylus and a target surface. The second optical distance measurement circuit is arranged at/on the other side of the active stylus to measure a second distance between the active stylus and the target surface. By using the first distance and the second distance, the signal processing circuit calculates an inclination angle of the active stylus relative to the target surface, and/or detects the rotation direction of the active stylus with the long axis direction as the rotation axis.

    Abstract: An electronic system is provided, which includes a first device and a second device. The first device includes a light source unit, a light detection unit and a control unit. The light source unit is utilized for emitting light along a light path. The light detection unit is utilized for detecting reflected light and measuring intensity of the reflected light. The control unit is utilized for generating a control signal according to the intensity of the reflected light. The second device includes a switch body and a reflection portion. The reflection portion is disposed on the switch body. When the reflection portion is located on the light path, the reflection portion reflects at least a portion of the light to form at least a portion of the reflected light.
