[0026] The following description is explained in more detail with reference to the drawings attached to this specification.

[0027] FIG. 1 of the drawings attached to this specification is a drawing illustrating an embodiment disclosed in this specification. FIG. 2 is a projected drawing of a part of the embodiment disclosed in FIG. 1. FIG. 3 is a drawing illustrating a cross-section of a sensing unit (100) of another embodiment.

[0028] First, the 3D information input device performs the same function as a conventional mouse, which inputs 2D information. The technology disclosed in this specification is a device that inputs 3D information to a terminal such as a computer by detecting a force that is pulled or pushed in the direction of movement while the user is holding it with their hand, just like a conventional mouse, and converting it into 3D information.

[0029] A three-dimensional information input device according to one embodiment with reference to the attached drawing includes a sensing unit (100), a supporting unit (200), and an information output unit (300).

[0030] The sensing unit (100) is provided as a polyhedron or sphere with at least four sides and detects the movement of a user in contact with the surface.

[0031] For example, the sensing unit (100) may include a sensing body (110) and a sensing unit (120).

[0032] The sensing body (110) may be provided in the shape of a polyhedron with at least four faces. That is, each face (111) is provided to face in a different direction. The sensing body (110) is provided so that a user can apply force in a three-dimensional direction by gripping it with their hand around the center of the spherical polyhedron. To explain in more detail, as shown in FIG. 3, the three-dimensional direction is determined based on each face (111).

[0033] The sensing unit (120) may be provided with a conventional pressure sensor or touch sensor, etc. The sensing unit (120) may be provided on each side (111) of the sensing body (110). The sensing unit (120) detects movement acting from the outside. Depending on the type of sensor used in the sensing unit (120), it may detect multiple forces acting from the outside of the sensing unit (100) or detect the movement of a user's hand in contact with the surface of the sensing unit (100).

[0034] Meanwhile, the sensing unit (120) may be installed on at least four sides (111) as needed (not shown).

[0035] Additionally, the sensing unit (120) may have different types of sensors provided on one face (111) (not shown), different sensors provided on each face (111) (not shown), and various sensors provided on the vertices and faces (111) of the polyhedron (not shown).

[0036] In another example, the sensing unit (100) may further include an outer body (130) provided in a spherical shape to surround the sensing body (110). The outer body (130) is provided to surround the sensing body (110), which is a polyhedral chain, and transmits an external force to the sensing unit (120). That is, the force provided to the outer body (130) is provided to transmit to the sensing unit (120). The outer body (130) transmits a force provided at a location away from the sensing unit (120) to the sensing unit (120).

[0037] Meanwhile, the sensing body (110) may be provided as a sphere. At this time, at least four sensing units (120) may be installed along the surface of the sensing body (110), and positioned so as to be spaced apart from each other.

[0038] Furthermore, the outer body (130) may be provided to cover only the sensing part (120).

[0039] A support member (200) may be provided on one side of the sensing member (100). The support member (200) allows the sensing member (100) to be positioned in the air. To explain in more detail, one side of the support member (200) is connected to the sensing member (100), and the other side is connected to the ground or another configuration so that the sensing member (100) is positioned in the air away from the ground. That is, the support member (200) is provided so that the user can selectively apply force to the entire surface of the sensing member (100). In other words, it allows the user to selectively apply force to the entire surface of the three-dimensional sensing member (100).

[0040] The information output unit (300) may be provided with software used in a conventional PCB or computer, etc. The information output unit (300) outputs the movement detected by the detection unit (100) as three-dimensional information.

[0041] For example, the information output unit (300) sets a direction corresponding to each face (111). For example, it can be set in the opposite direction where the sensing unit (120) is installed, centered on the sensing unit (120). The information output unit (300) determines the set direction through the sensing unit (120) where an external force is detected. That is, it can be said that the direction in which a normal mouse cursor moves is determined. The information output unit (300) converts the direction into coordinate values, etc., and transmits them to the terminal.

[0042] Meanwhile, the information output unit (300) can more accurately calculate the direction intended by the user by removing information below a predetermined detection value (pressure) from among a plurality of detection values ​​detected by the detection unit (100) when the user is in a state where the user is wrapping the detection unit (100) with their hand, that is, when the user is in a state where the user is wrapping the detection unit (100) with their hand.

[0043] Furthermore, as shown in FIG. 3, the information output unit (300) may further include setting the direction orthogonal to the surface where the sensing unit (120) is located, where the highest detection value among the multiple detection values ​​is detected, as the direction of movement, and correcting the coordinate movement direction for the remaining detection values.

[0044] Of course, the information output unit (300) can calculate a direction that matches the user's intention by using multiple detection values ​​detected by the detection unit (100) through various methods such as artificial intelligence and triangulation.

[0045] Furthermore, the information output unit (300) may include artificial intelligence that takes real-time measurement values ​​of the sensing unit (120) as input values, analyzes the positional distribution of force applied to the detection unit (100), and outputs the result.

[0046] The three-dimensional information input device described above has the effect of enabling intuitive operation by allowing a user to apply force in various three-dimensional directions along the surface of the sensing unit (100) through a spherical sensing unit (100) positioned in the air by a support unit (200), and at the same time, to provide a three-dimensional information input device capable of calculating and providing three-dimensional directions through an information output unit (300).

[0047] Meanwhile, as shown in FIG. 3, the edge of the surface (111) of the sensing body (110) may further include a blocking projection (400) that is protruded through the outer body (130) and exposed to the outside. The blocking projection (400) separates the outer body (130) to correspond to each surface (111). The blocking projection (400) has the effect of reducing the calculation error of the information output unit (300) by preventing the force transmitted through the outer body (130) from being detected by the sensing unit (120) provided on the other surface (111).

[0048] Furthermore, the three-dimensional information input device described above may detect movement along the surface of the sensing part (100) while the user applies force with a finger or the like, and may calculate and provide three-dimensional spatial information.

[0049] In addition, the sensing unit (100) may further include a conventional vibration motor.

[0050] From the foregoing, it will be understood that various embodiments of the present disclosure have been described for illustrative purposes, and that various possible modifications exist without departing from the scope and spirit of the present disclosure. Furthermore, the various embodiments disclosed are not intended to limit the spirit of the present disclosure, and the true spirit and scope will be set forth in the following claims.
