Abstract
A touch pen using a delay device and a touch input method thereof and a touch input system and a method thereof are provided. The touch pen includes a body, an antenna embedded on the body configured to receive a wireless signal from a mobile terminal, and a delay device configured to receive the wireless signal from the antenna and to output a reflection signal, corresponding to the received wireless signal, to the antenna after a predetermined time elapses, wherein the antenna transmits the reflection signal to the mobile terminal.
Claims32
A touch pen comprising:
- a body;
- an antenna configured to receive a wireless signal from a mobile terminal;
- and
- a delay device configured to:
- receive the wireless signal from the antenna,
- convert the wireless signal into an acoustic wave, and
- output a reflection signal, corresponding to the acoustic wave, to the antenna after a predetermined time elapses,
- wherein the antenna transmits the reflection signal to the mobile terminal.
A touch input system comprising:
- a touch pen including:
- an antenna, and
- a delay device configured to:
- receive a wireless signal through the antenna,
- convert the wireless signal into an acoustic wave,
- generate a reflection signal corresponding to the acoustic wave after a predetermined time elapses, and
- transmit the generated reflection signal through the antenna;
- and
- a mobile terminal configured to:
- transmit the wireless signal to the touch pen,
- receive the reflection signal generated by the delay device, and
- recognize location information and status information of the touch pen.
A method of inputting a touch, the method comprising:
- transmitting a wireless signal for recognizing location information and status information of a touch pen by a mobile terminal;
- receiving the wireless signal transmitted from the mobile terminal through an antenna by the touch pen;
- receiving the wireless signal from the antenna;
- outputting a reflection signal corresponding to the received wireless signal to the antenna after a predetermined time elapses by a delay device of the touch pen, wherein the predetermined time is associated with converting the wireless signal into an acoustic wave;
- transmitting the reflection signal to the mobile terminal through the antenna of the touch pen;
- receiving the reflection signal by the mobile terminal;
- and
- recognizing at least one of the location information and the status information of the touch pen by analyzing the reflection signal by the mobile terminal.
A method of inputting a touch of a touch pen, the method comprising:
- receiving a wireless signal through an antenna;
- delaying the received wireless signal for a predetermined time by using a delay device, wherein the predetermined time is associated with converting the wireless signal into an acoustic wave;
- outputting a reflection signal corresponding to the wireless signal to the antenna;
- and
- transmitting the reflection signal through the antenna.
