  • Interactive system capable of switching different writing modes and handheld member thereof
    Patent number: 10126841
    Abstract: An interactive system includes a handheld member and a display module. The handheld member has a first near field communication tag and a second near field communication tag. The first near field communication tag generates a first near field signal, and the second near field communication tag generates a second near field signal. The display module includes a near field sensing unit and a control unit. The near field sensing unit is for sensing the first near field signal or the second near field signal. The control unit is coupled to the near field sensing unit and selectively performs a first function when the near field sensing unit senses the first near field signal or performs a second function when the near field sensing unit senses the second near field signal.
