The user input unit 145 receives various commands from a user. The user input unit 145 includes at least one of a key 146, a touch panel 147147, and a pen recognition panel 148.
The key 146 includes various types of keys such as a mechanical button, a wheel, etc. disposed in various regions such as a front part, a side part, a rear part, etc. of a body of the electronic device 100a.
The touch panel 147 senses a touch input of the user and outputs a touch event value corresponding to the sensed touch signal. When the touch panel 147 is combined with the display panel 111 to configure a touch screen, the touch screen may be implemented with various types of touch sensors such as a capacitive touch sensor, a pressure sensitive touch sensor, a piezoelectric touch sensor, etc. A capacitive type is a method that, by using dielectric coated on a surface of a touch screen, senses fine electricity which is applied to a user body when a part of the user's body touches the surface of the touch screen, and calculates touch coordinates by using the sensed electricity. A pressure sensitive type is a method that, by using two electrode plates (an upper plate and a lower plate) built into a touch screen, senses a current that is generated by a contact between the upper plate and the lower plate at a touched position when a user touches a screen, and calculates touch coordinates by using the sensed current. A touch event occurring in a touch screen is generally generated by a person's finger, but may be generated by an object including a conductive material for changing a capacitance.
The pen recognition panel 148 senses a pen proximity input or a pen touch input which is applied thereto by a touch pen (for example, a stylus pen), a digitizer pen, etc., and outputs a sensed pen proximity event or a pen touch event. The pen recognition panel 148 may be implemented in, for example, an EMR type. The pen recognition panel 148 senses a touch or proximity input, based on an intensity change of an electromagnetic field generated by a proximity or a touch of a pen. In detail, the pen recognition panel 148 includes an electronic signal processing unit that sequentially supplies an alternating current (AC) signal having a certain frequency to an electronic induction coil sensor having a grid structure and a loop coil of the electronic induction coil sensor. When a pen with a built-in resonance circuit is located near the loop coil of the pen recognition panel 148, a magnetic field transmitted from the loop coil generates a current based on mutual electronic induction in the resonance circuit of the pen. An inductive magnetic field is generated from a coil configuring the resonance circuit of the pen, based on the current. The pen recognition panel 148 detects the inductive magnetic field in the loop coil which is in a state of receiving a signal, and senses a proximity position or a touch position of the pen. The pen recognition panel 148 may be provided to have a certain area (for example, an area for covering a display area of the display panel 111) at a lower portion of the display panel 111.
The microphone unit 150 receives user voice or other sound and converts the received voice or sound into audio data. The control unit 170 uses the user voice, input through the microphone unit 150, in a call operation or converts the user voice into the audio data to store the audio data in the memory 120.
The photographing unit 155 captures a still image or a moving image according to control by the user. The photographing unit 155may be provided in plurality like a front camera, a rear camera, etc.
When the photographing unit 155 and the microphone unit 150 are provided, the control unit 170 performs a control operation according to a user voice, which is input through the microphone unit 150, or a user motion recognized by the photographing unit 155. For example, the electronic device 100a operates a motion control mode or a voice control mode. When the electronic device 100a operates in the motion control mode, the control unit 170 activates the photographing unit 155 to allow the photographing unit 155 to photograph the user and traces a motion change of the user to perform a control operation corresponding to the motion change. When the electronic device 100a operates in the voice control mode, the control unit 170 analyzes the user voice input through the microphone unit 150 and operates in a voice recognition mode of performing a control operation according to the analyzed user voice.
The motion detection unit 165 senses a movement of the electronic device 100a. The electronic device 100a may be rotated or inclined in various directions. In this case, the motion detection unit 165 senses movement characteristics such as a rotation direction, a rotated angle, a slope, etc. by using at least one of various sensors such as a geomagnetic sensor, a gyro sensor, an acceleration sensor, and/the like.
In addition, the electronic device 100a may further include a universal serial bus (USB) connectable to a USB connector, various external input ports connectable to various external devices such as a headset, a mouse, a local area network (LAN), etc., a digital multimedia broadcasting (DMB) chip that receives and processes a DMB signal, and/or various sensors.
Names of the above-described elements of the electronic device 100a may be changed. Also, the electronic device 100a may be configured with at least one of the above-described elements. However, some elements may be omitted, or the electronic device 100a may further include another element.
