Claims (5)

1 . A protruding feedback-based smart tablet comprising a plurality of output units, wherein the protruding feedback-based smart tablet comprises an expression area in which the plurality of output units are arranged, wherein the plurality of output units each comprises an expression unit which is sensible by a user and formed to protrude in response to a movement of an input pen when the user performs an input operation, wherein the expression unit of at least one output unit of the plurality of output units is formed to protrude by a magnetic field, wherein, after removing the magnetic field, the protruded form of the expression unit is maintained for a certain period of time by a support structure, and wherein the protruded form of the expression unit is performed by an angular or rotational movement, via the magnetic field, of either the expression unit or a member configured to move the expression unit.
2 . The protruding feedback-based smart tablet of claim 1 , wherein the output unit comprises a magnetic body to generate the magnetic field.
3 . The protruding feedback-based smart tablet of claim 1 , further comprising a reset member configured to release a protruding state of the expression unit to maintain a non-protruding state of the expression unit.
4 . The protruding feedback-based smart tablet of claim 3 , wherein the reset member controls a movement for the expression unit by using a magnetic field.
5 . The protruding feedback-based smart tablet of claim 4 , wherein the reset member simultaneously releases a protruding state of a plurality of expression units to maintain a non-protruding state of the expression units.

Description

CROSS REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. application Ser. No. 17/596,515 filed Dec. 13, 2021, which is a National Stage of International Application No. PCT/KR2019/017414 filed Dec. 10, 2019, claiming priority based on Korean Patent Application No. 10-2019-0110786 filed Sep. 6, 2019 and Korean Patent Application No. 10-2019-0110787 filed Sep. 6, 2019. TECHNICAL FIELD The present disclosure relates to an input feedback-based smart pen and a protruding feedback-based smart tablet. BACKGROUND ART Users may perceive information in various ways. For this purpose, various types of information output devices are used. For example, an apparatus for outputting visual information using printed materials, an apparatus for outputting audio information through sound, etc. are being used. Meanwhile, users may perform input operations through manipulations in various forms according to their intentions. For example, a user may write or draw on paper by using a pen. As a result of such an input operation, for example, text or a drawing may be visually recognized. However, when a result of such an input operation is directly sensed, for example, there are cases in which it is difficult to visually detect a text or a drawing written on paper. and thus there is a limit of improving user convenience regarding sensing of a result of an input operation of a user. On the other hand, due to technological development and diversification of lifestyles, various types of information output formats are required. In addition, it is required to output such that the content input by the user can be detected at the time of such output. For example, various information output devices may be demanded according to situations of users, and more particularly, it is demanded to tactilely output information as a feedback to an input content for a user with a specific sensory handicap, e.g., visual handicap. When information is output tactilely, it is difficult to control the output easily and stably, and thus there is a limit of improving user conveniences through the improvement of information output devices. DESCRIPTION OF EMBODIMENTS Technical Problem Embodiments of the present disclosure provide an input feedback-based smart pen capable of improving user convenience by facilitating a feedback on a user's input operation. Embodiments of the present disclosure provide a protruding feedback-based smart tablet that allows a user to easily sense output information corresponding to an input and improves user convenience. Solution to Problem According to an embodiment of the present disclosure, an input feedback-based smart pen includes a main body having a shape that enables manipulation of a user; an input unit connected to the main body and performing an input operation by a manipulation of the user; an input information recognition unit configured to recognize information input by a user through the manipulation of the input unit; and an expression unit including one or more expression members formed in an area of an outer surface of the main body to be detectable by the user to express information corresponding to input information recognized by the input information recognition unit. According to the present embodiment, the input feedback-based smart pen may further include an information processing unit configured to process one or more pieces of information by using contents recognized by the input information recognition unit and delivers processed information to the expression unit. According to the present embodiment, the input feedback-based smart pen may further include an operation control unit formed to be manipulated by a user to control one or more operations regarding the expression unit. According to the present embodiment, the expression unit may include a plurality of expression members, and different information may be delivered to a user according to protruding shapes of the plurality of expression members. According to the present embodiment, the input feedback-based smart pen may further include a speaker configured to output the one or more pieces of information. According to an embodiment of the present disclosure, a protruding feedback-based smart tablet includes one or more output units, wherein the protruding feedback-based smart tablet includes an expression area in which one or more output units are arranged, and the one or more output units each includes an expression unit formed and disposed to be sensible by a user and formed to protrude in response to a movement of an input pen when the user performs an input operation on the expression area by using the input pen. According to the present embodiment, the input pen may include one or more magnetic bodies, and the expression unit may move by a magnetic field generated by the one or more magnetic bodies. According to the present embodiment, the output unit may include a magnetic body to generate a magnetic field together wit
