| description | An apparatus with both touch sensing and electrical field sensing functions and an interactive apparatus using the same are provided. The apparatus with both touch sensing and electrical field sensing functions comprises a control circuit, a first capacitive sensing electrode and a second capacitive sensing electrode. The first capacitive sensing electrode is coupled to a first sensing control terminal of the control circuit. The second capacitive sensing electrode is coupled to a second sensing control terminal of the control circuit. In a first period, the first capacitive sensing electrode is charged to a first voltage through the first sensing control terminal, and the second sensing control terminal supplies an electrical field pulse to the second capacitive sensing electrode such that the second capacitive sensing electrode outputs an electrical field pulse signal. In the first period, the control circuit determines whether the first capacitive sensing electrode is touched or not according to a period, during which a voltage of the first capacitive sensing electrode is discharged from the first voltage to a second voltage, and determines whether the second capacitive sensing electrode approximates the first capacitive sensing electrode or not according to whether the first capacitive sensing electrode synchronously detects the electrical field pulse or not. |
