Description

A Keyboard with A Object Camera and A Object Sensor}

In an input device to which a physical keyboard keyboard is applied, an object camera that photographs the movement of an object such as a user's bare hand or a hand holding an instrument outside the keyboard area is provided with a first inclined surface formed at the vertical edge of the keyboard body or rotatable. It is applied to a rotating body assembled in a state, and it relates to an object camera and a keyboard equipped with a detection sensor capable of performing a navigation operation function through motion recognition of an object using a physical keyboard equipped with an object camera without a mouse and a touch pad.

Since the application of the image input device to desktop computers began, a patent (Korean Patent 10-2002-0062714) that applied the image input device to the keyboard so that users can more accurately input the video chat screen was proposed, but it was not universalized.

Laptops, which are still widely used today, are being evaluated as a productivity tool that can be carried within a limited range due to the keyboard being applied on one side of the folding side. However, due to the limitation of shape invariance, carrying in a high state such as a one-handed grip It is not satisfactory, and even with a touch pad, it does not reach the productivity of the mouse.

As a mobile device with excellent portability, easy Internet search, and equipped with a shooting function, the user's environment has rapidly shifted from the desktop environment to the mobile environment after the advent of smartphones and tablets.

However, it is convenient to use image information in the conventional plate-shaped smartphone, but unlike a desktop or laptop computer, keyboard input and mouse input are limited, which makes it inconvenient to be used as a productivity tool.

Likewise, a tablet device having a plate shape also had a problem that it was difficult to input keyboard and mouse input, and a two-in-one product with a detachable cover applied with a keyboard function applied to one side covering the screen display surface of the tablet device was released. Although the same problem has been solved, the problems of inconvenient portability that cannot be gripped with one hand, the occurrence of scratch marks in contact with the keyboard on the screen display surface, and the use of a mouse input device, which is important as a productivity tool, are not solved.

In addition, the patent filed by the inventor (Korea Patent Application No.: 10-2017-0096694) achieved the purpose of increasing portability and productivity by applying a keyboard that can be attached and stored in an image display device, but due to the application of its own keyboard. There is a problem in that the battery application space of the image display device is reduced, and it is cumbersome to unfold and fold the camera module applied to the detachable keyboard.

In addition, in the case of existing flat-type smartphones, a product in which a rotating camera that can shoot both the front and the back with a single camera is applied to one corner or a product in which the camera is accommodated and protruded at one corner has been released by some manufacturers.

The technical problem to be achieved by the present invention is as follows.

First, in an image display device using a physical keyboard as an input device, it is intended to be able to perform productivity tasks such as a desktop to which a mouse is applied without carrying a separate mouse, only with a physical keyboard connected to the image display device.

Second, to reduce unnecessary resource consumption due to the physical keyboard with motion recognition function of the object being maintained in the standby mode at all times, and to enable automatic activation and deactivation of the motion recognition function even if the user does not perform a separate manual on-off operation. do.

Third, the keyboard input activity using the physical keyboard and the navigation operation activity through gesture recognition are not confused.

In order to achieve the above technical task, the first embodiment of the present invention is an input device having a keyboard and a keyboard body to which the keyboard is applied, and the keyboard is positioned at one of the vertical edges shorter than the horizontal side of the keyboard body. An object camera that photographs objects such as a user's finger, a bare hand, or a hand holding an instrument, which is applied to the first slope and is positioned in front of the first slope, which is formed by inclining and not parallel to the applied surface, and An object detection sensor is applied that is applied to a first slope or a body outside the first slope to detect an object entering or leaving the wide-angle area of the object camera and transmits the detected signal to the image display device.

In the first embodiment, the vertical axis of the first inclined surface and the vertical axis of the application surface of the keyboard applied to the keyboard body form an acute angle.

In the first embodiment, the keyboard body is a plate-shaped body that cannot be folded and wound, a foldable body that can be folded based on a folding axis, a rollable body that can maintain a wound state, and a protective cover body that has a protective cover function in addition to the keyboard. It consists of either one.

In the first embodiment, a second inclined surface is formed outside the wide-angle area at one end of the first inclined surface to secure a wide-angle area of the object camera.

The second embodiment, which is another embodiment of the present invention, is an input device including a keyboard and a keyboard body to which the keyboard is applied, and a rotating body that is applied in a rotatable state to any one of vertical corners that are shorter in length than the horizontal side of the keyboard body, It is applied to one side of the keyboard body or the rotating body and is applied to the rotating shaft detection sensor or switch that detects the rotation of the rotating body of the rotating body, and it is applied to one side of the rotating body to photograph objects such as a moving user's finger, bare hand, or a hand holding the device. It is configured to include an object camera.

In the second embodiment, an object detection sensor is applied to one surface of the rotating body to which the object camera is applied or the keyboard body outside the rotating body to detect an object entering or leaving the wide-angle area of the object camera and to transmit the detected signal.

In the second embodiment, the object detection sensor is activated only when a rotation axis detection sensor or a switch detects that the rotation body has reached a set rotation angle.

In the first and second embodiments, the object detection sensor is a thermal sensor that detects heat of an object entering or leaving the wide-angle area of the object camera, a static charge sensor that detects an electrostatic charge, and a magnetic field that detects a change in a magnetic field. Any one or more of a sensor, a distance sensor using ultrasonic reflection, and an illuminance sensor that detects a change in illuminance is applied.

As described above, according to the embodiments of the present invention, it has the following advantages.

First, since an object camera that recognizes a user's motion is applied to a horizontal edge of a physical keyboard connected to an image display device, productivity tasks such as a desktop with a mouse can be performed without carrying a separate mouse.

Second, the user's hand or finger entering or exiting the wide-angle area of the object camera without performing a separate manual on-off operation by the user because the object detection sensor is applied to the physical keyboard to which the object camera with motion recognition function is applied. As the object camera is activated by automatically detecting the camera, unnecessary power consumption and user inconvenience can be eliminated.

Third, the keyboard input activity and the navigation operation activity related to motion recognition are confused by the object camera being inclined at the edge of the vertical part of the physical keyboard where the keyboard input takes place, so that the keyboard input area and the motion recognition area are separated. It will not be.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The terms used in the present specification are for describing exemplary embodiments and are not intended to limit the present invention. In this specification, the singular form also includes the plural form unless specifically stated in the phrase. In addition, reference numerals presented according to the order of description are not necessarily limited to the order, and some of the numerals assigned thereto may be omitted from the drawings.

In general, a working environment for creating documents using a desktop or laptop requires a working board, a physical keyboard, a mouse pad, and a mouse.

Among these components, the mouse pad and mouse are separate components from the desktop and notebook, and must be carried separately, and cannot be used in an empty space without a working board such as a desk.

In addition, navigation operations such as screen movement, reduction, enlargement, and double-click of the smartphone are mainly performed by the touch operation of the touch panel using the user's hand, along with the disadvantage that the user's hand covers a large part of the screen display during touch operation. During the process of the finger continuously touching the outer surface of the screen display device, scratches occur and both the smartphone and fingers are contaminated.

If the front camera is applied to a tablet to which a virtual keyboard can be applied to detect the motion of an object such as a user's finger or hand, unlike a smartphone, interference in the wide-angle area does not occur, but the user's hand is displayed on the screen. Along with the problem of covering part of the device, the same problem exists that the front camera must be always activated.

In addition, in the case of existing flat-type smartphones, a product that has a rotating camera that can shoot both the front and the rear with a single camera was applied to one corner of the flat-type smartphone body, but it is a product specialized for still image and video shooting, so that the user can manually shoot. In addition to the inconvenience of performing activation and deactivation directly, fingerprint marks remain on the camera lens by a finger, there is an inconvenience that the user must set a rotation angle for performing image recognition for navigation operation each time.

Unlike the above, a patent (Korean Patent 10-2002-0062714) that applied an image input device to a keyboard was proposed so that users can more accurately input the video chat screen, and through this concept, a motion recognition that replaces a mouse is performed. A plan can also be considered, but it is not widely used because of the following problems.

First, when performing motion recognition of an object using a front camera positioned at the center of the rear horizontal side of the keyboard body, there is a problem that the wide-angle area for recognizing the motion of the front camera and the keyboard input area for performing the keyboard input overlap.

Second, there is a problem that the front camera must always be activated to perform object motion recognition, and even if a simple physical switch or virtual switch that performs activation and deactivation of the front camera is applied to solve the problem, the user There is a new problem of the hassle of having to manually perform activation and deactivation.

As one of the alternatives to solve the above problems, a patent (Korean Patent Application No.: 10-2017-0096694) has been filed by the inventor, but the application of a detachable keyboard reduces the battery application space of the body and makes it difficult to fold and unfold the camera module. There is a problem that it is cumbersome.

Accordingly, the present invention has been derived to solve the following problems.

First, in an image display device using a physical keyboard rather than a virtual keyboard as an input device, it is intended to be able to perform productivity tasks such as a desktop with a mouse applied only with a physical keyboard connected to the image display device without carrying a separate mouse.

Second, to reduce unnecessary resource consumption due to the physical keyboard with motion recognition function of the object being maintained in the standby mode at all times, and to enable automatic activation and deactivation of the motion recognition function even if the user does not perform a separate manual on-off operation. do.

Third, the keyboard input activity using the physical keyboard and the navigation operation activity through gesture recognition are not confused.

In order to solve the above problems, the present invention is the first embodiment in which the first inclined surface 120 is applied to the keyboard body 110 and the rotating body to the keyboard body 110 together with the illustrated drawings of FIGS. 1 to 21. Examples are roughly presented as second embodiments to which 150 is applied, and various detailed embodiments are presented according to the characteristics of the keyboard body 110 in each embodiment.

Is a cross-sectional view of an object camera and an object detection sensor of, and FIG. 11 is a first inclined surface, an object camera, and a first inclined surface at the vertical edge of the first embodiment to which a protective cover body with a protective cover function is applied along with a keyboard like a protective cover of a surface product. A front view, a plan view, a side view, and a partial detailed view to which the object detection sensor is applied, FIG. 12 is a plan view and a partial detailed view of FIG. 11, and FIG. 13 is a cross-sectional view of the object camera and the object detection sensor of FIG. 12.

As shown in FIGS. 1 to 13, the first embodiment is an input device having a keyboard 101 and a keyboard body 110 to which the keyboard is applied, and is a vertical edge whose length is shorter than that of the horizontal side of the keyboard body 110. A user who moves by being applied to the first inclined surface 120 and the first inclined surface 120 formed by inclining and not parallel to the application surface of the keyboard 101 at one of the corners and located in front of the first inclined surface 120 The object camera 130 is applied to the object camera 130 and the keyboard body 110 outside the first inclined surface 120 or the first inclined surface 120 to photograph an object such as a finger, a bare hand, or a hand holding an instrument. An object detection sensor 140 is applied that senses an object entering or leaving the wide-angle area of and transmits the detected signal to the image display device.

As shown in FIG. 1, the application of the first inclined surface 120, the object camera 130, and the object detection sensor 140, which are components of the first embodiment, to the edge of the keyboard body 110 It can be considered for the front horizontal and vertical corners.

When the first slope 120, the object camera 130 and the object detection sensor 140 are applied to the vertical edge, the user's character input behavior using the keyboard 101 and the user's motion beyond the keyboard 101 are recognized. It has the advantage that the behavior is clearly separated and no mutual interference error occurs.

However, when the first slope 120, the object camera 130, and the object detection sensor 140 are applied to the front horizontal edge of the keyboard body 110, the user's character input behavior using the keyboard 101 and the user's Motion recognition A problem occurs in which areas for action overlap with each other, and this causes an error in motion recognition.

Therefore, in the first embodiment of the present invention described later, the application of the first inclined surface 120, the object camera 130, and the object detection sensor 140 is applied to the vertical side of the keyboard body 110, and is additionally applied to the front horizontal side. Further application may be considered.

In addition, as shown in 2, the motion recognition object of the first embodiment using the object camera 130 may be an object such as a user's finger positioned in front of the first slope 120, a bare hand, or a hand holding an instrument. I can.

4, 6, 8, 10, and 13, the vertical axis of the first inclined surface 120 and the vertical axis of the application surface of the keyboard 101 applied to the keyboard body 110 in the first embodiment are acute angles. To form.

Since the first inclined surface 120 is formed at an acute angle at the corner of the keyboard body 110, the user smoothly senses the user's hand outside the keyboard input area even in a space without a working plate such as a desk and in various environments such as on the working plate. You can do it, so you can perform navigation operations that were performed with a mouse without a mouse.

If the first inclined surface 120 is applied to the keyboard body 110 at a right angle rather than an acute angle, the problem does not occur in a space without a working plate, but in a situation where it is placed on the working plate or on the knee, the object camera 130 The camera wide-angle axis 131 of the object camera 130 along with the inconvenience that the user's hand must move by rubbing the working plate or knee due to the relationship in which the camera wide-angle axis 131 of) faces the working plate surface or the knee surface. ) There is a disadvantage that it is impossible to utilize half of the wide-angle area located at the bottom.

As another case, when the first inclined surface 120 is maintained at an obtuse angle beyond the right angle to the keyboard body 110, most of the wide-angle region is applied to the lower portion of the camera wide-angle axis 131 of the object camera 130. There is a problem that the range of the usable wide-angle area becomes narrower than that in the case of a right angle.

1 to 13, in the first embodiment, the keyboard body 110 has a plate-shaped body that cannot be folded and wound, a foldable body that can be folded based on a folding axis, a rollable body that can maintain a wound state, and a keyboard.

5 to 8, when the first inclined surface 120 is formed at one corner of the foldable body that can be folded based on the folding axis, the first inclined surface protrusion to secure the applied thickness of the object camera 130 Part 121 is formed to protrude higher than the plate-shaped thickness of the foldable body, and the protrusion height of the first inclined surface protrusion 121 does not exceed the thickness of the foldable body in the folded state.

11 to 13, when the first inclined surface 120 is formed at one edge of the protective cover body with a protective cover function, the first inclined surface protrusion ( 121) is formed to protrude a portion higher than the thickness of the plate-shaped keyboard body, and the first inclined surface protrusion 121 corresponds to the perimeter of the image display device so as not to interfere with the plate-shaped image display device 10 when performing the protective cover function of the keyboard body. It is formed in an area outside the circumference of the keyboard body 110.

1 to 13, an object detection sensor that detects an object entering or leaving the wide-angle area of the object camera 130 applied to the first inclined surface 120 and transmits the detected signal to the image display device ( 130) is preferably disposed so that the object camera 130 is activated and immediately enters the shooting mode while detecting that the user's hand outside the keyboard input area enters the wide-angle area of the object camera 130. This arrangement This has the advantage of minimizing the waiting time for motion recognition.

To this end, in the first embodiment, the object detection sensor 140 is applied to a portion adjacent to the object camera 130 of the first slope 120.

14 is a front view, a plan view, a side view, and a partial detail view to which a rotating body, an object camera and an object detection sensor are applied to a vertical edge of the second embodiment to which a plate-shaped body is applied, and FIG. 15 is an object camera of FIG. And cross-sectional views of the object detection sensor, and FIG. 16 is a front view, a plan view, a side view, and a partial detail view of an embodiment in which the rotating body of FIG. 14 is rotated to perform motion recognition and maintained in an inclined state. 17 is a cross-sectional view of the object camera and object detection sensor of FIG. 16, and FIG. 18 is a rotating body, an object camera, and an object detection sensor in an unrotated state at the vertical edge of the second embodiment to which a foldable body capable of a fully unfolded state is applied Is a front view, a plan view, a side view and a partial detail view to which is applied, FIG. 19 is a cross-sectional view of the object camera and object detection sensor of FIG. 18, and FIG. 20 is a front view, a plan view, a side view, and a partial detail of the folded state of FIG. 18 And FIG. 21 are cross-sectional views of the object camera and object detection sensor of FIG. 20.

14 to 21, the second embodiment, which is another embodiment of the present invention, is an input device having a keyboard 101 and a keyboard body 110 to which the keyboard is applied, compared to the horizontal side of the keyboard body 110. It is applied to any one side of the rotating body 150, the keyboard body 110, or the rotating body 150, which is applied in a rotatable state to any one of the short longitudinal corners, and detects the rotation of the rotating shaft of the rotating body 150. It is configured to include a rotating shaft detection sensor or switch 152 and an object camera 130 that is applied to one surface of the rotating body 150 to photograph an object such as a moving user's finger, a bare hand, or a hand holding the device.

However, in the case of applying the rotating body 150, the object camera 130 and the object detection sensor 140 to the front horizontal edge of the keyboard body 110 with a concept similar to that of FIG. 1, the user's character using the keyboard 101 A problem occurs in which the input behavior and the region for the user's motion recognition behavior overlap each other, and this causes an error in motion recognition.

Therefore, in the second embodiment of the present invention described later, the application of the rotating body 150, the object camera 130, and the object detection sensor 140 is applied to the vertical side of the keyboard body 110, and is additionally applied to the front horizontal side. This may be further considered.

In addition, as shown in FIG. 2 of the first embodiment, the motion recognition target using the object camera 130 of the first inclined surface 120 is located in front of the object camera 130 of the rotating body 150 in the case of the second embodiment. It could be an object such as a user's finger, bare hand, or a hand holding an instrument.

In the second embodiment, one surface of the rotating body 150 to which the object camera 130 is applied or the keyboard body 110 outside the rotating body 150 detects an object entering or leaving the wide-angle area of the object camera 130 The object detection sensor 140 for transmitting the detected signal is applied.

This has the advantage of minimizing the waiting time for motion recognition.

In the second embodiment, the object detection sensor 140 is activated only when it is detected by the rotation axis detection sensor or the switch 152 that the rotation body 150 has reached a set rotation angle.

In the second embodiment, the object detection sensor 140 is activated only when it is recognized that the rotation axis detection sensor or the switch 152 has reached a specific set angle, so that the rotation body 150 is not rotated. When the camera wide-angle axis 131 of the camera 130 and the vertical axis of the screen display surface 11 become parallel, the object camera 130 is activated only when the user rotates the rotating body 150 to switch to the motion recognition standby state. It is possible to reduce unnecessary power consumption by having the characteristics that can be achieved.

In the first and second embodiments, the object detection sensor 140 is a thermal sensor that detects heat of an object entering or leaving the wide-angle area of the object camera 130, a static charge sensor that detects an electrostatic charge, Any one or more of a magnetic field sensor that detects a change in a magnetic field, a distance sensor using ultrasonic reflection, and an illuminance sensor that detects a change in illuminance is applied.
