Apparatus of game using active type screen function }

The present invention relates to a game device, and more particularly, to a device for actively enjoying various games using images such as sports and games projected on a screen by a projector.

Similar to virtual reality, the active screen function refers to an interface in which users and computers interact with real surrounding situations and environments. Active screens allow users to show and manipulate as if they were in the environment without experiencing them firsthand. These active screens are being used for various purposes, and in particular, in schools, games such as various sports and games are being used. For example, students can enjoy various games by using a screen with an active screen function capable of location recognition.

Currently, the position recognition device suggested in the above patent is utilized for games such as sports and play. Specifically, a game image is displayed on the screen, and the game is operated by a user touching the screen. However, since the conventional game device is fixed to the wall of a gym, it is inconvenient to apply it to an actual game. In reality, it is desirable to play the game on the floor of the gym rather than on the wall. That is, it is necessary to move the game device. In addition, conventionally, the user's movement in front of the screen cannot be sensed, so there is a limit to variously operating the game.

An object to be solved by the present invention is to provide a game device using an active screen function that is free to move and that can actively and variously operate a game by sensing a user's movement in the front along with touch sensing on the screen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments described below may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described in detail below. The embodiments of the present invention are provided to more completely explain the present invention to those of ordinary skill in the art. On the other hand, terms indicating positions such as upper, lower, front, etc. are only related to those shown in the drawings. In fact, the game device can be used in any optional orientation, and in actual use, the spatial orientation changes according to the orientation and rotation of the game device.

An embodiment of the present invention actively applies a combination of a position sensor and a proximity sensor to a game, so that movement is free, and it is possible to actively and variously operate the game by detecting the user's movement in the front with touch sensing on the screen. game equipment is presented. To this end, a game device in which a position sensor and a proximity sensor are combined will be studied in detail, and a method of operating a game by the game device will be described in detail. The game in the embodiment of the present invention includes all sports such as soccer, baseball, handball, and games such as balloon popping.

1 is a schematic diagram for explaining a first game device 100 according to an embodiment of the present invention. However, the drawings are not expressed in a strict sense, and there may be components not shown in the drawings for convenience of description.

1 , a first game device 100 includes a screen frame 10 on which a screen 11 is mounted, a touch sensor 20 , proximity sensors 30 and 31 on the screen, and a projector 40 . . On the screen 11, through the project 40, sports such as soccer, baseball, handball, etc. and game images such as games such as balloon popping are enlarged and projected. The above video is an appropriately edited video for the purpose of the game. For example, in the case of a soccer game, the image includes a goalpost, a goalkeeper, and the like. A wheel 12 which is a moving means is mounted on a lower portion of the screen frame 10 and includes a control unit 13 for controlling the first game device 100 . When the wheels 12 are mounted, the first game device 100 is not fixed to the wall, unlike in the related art, but can be moved to a location necessary for a game, for example, on the floor of a gymnasium that is a game room.

The touch sensor 20 includes all methods for identifying an object touched on the screen 11 . However, the present invention is preferably a position recognition device for recognizing the position of an object using a laser beam as in Korean Patent Registration No. 10-1097992. Because, other methods than the laser beam, for example, the capacitive method, the resistive method, the conductive line pattern method, etc., have to form a touch sensing means such as a capacitance, a resistance, a conductive line on the screen 11. However, this is because the touch sensing means is difficult to be practically applied to the large-area screen 11 and requires a lot of cost. On the other hand, in the screen 11 of the present invention, an image is enlarged and projected by the projector 40 , and the position recognition in the image uses a laser beam and retroreflection disposed around the screen 11 . In other words, a separate touch sensing means is not required for the screen 11 unlike capacitance, resistance, and conductive lines.

In particular, when the game device of the present invention is applied to students, the students not only simply touch the screen 11 , but also apply an impact such as hitting or hitting the screen 11 . However, when the touch sensing unit is formed on the screen 11, the touch sensing unit is damaged by the impact. However, there is no touch sensing means on the screen 11 of the game device of the present invention, and only serves to project the game image. Accordingly, even when students apply an impact to the screen 11 , the screen 11 is not damaged. Since the projector 40 is required to project the game image on the screen 11 , the combination of the projector 40 and the screen 11 is an essential component.

The touch sensor 20 irradiates a laser beam parallel to the screen 11 on the upper part of the screen 11 in order to check whether a touch is made on the screen 11 (a). The laser beam utilizes a rotating scanning means, and analyzes the laser beam that is retro-reflected by the reflection means to confirm the touch. For this, reference will be made to Korean Patent No. 10-1097992. The touch sensor 20 is preferably located on one side of the screen 11, preferably in the middle of the upper screen frame 10, in order to increase scanning efficiency.

The proximity sensors 30 and 31 on the screen confirm the position and trajectory of the target. The object is a user and a play equipment used for play. The proximity sensors 30 and 31 are preferably disposed on one side of the screen frame 10 , preferably at least two proximity sensors on both sides of the touch sensor 10 . When the two proximity sensors 30 and 31 are mounted, the position and trajectory of the target can be accurately grasped by combining the position angle with respect to the target using a known method. In order to confirm the position and trajectory of the target, the proximity sensors 30 and 31 may operate in at least one method selected from an ultrasonic method, a laser method, an infrared method, and an image method. That is, the proximity sensors 30 and 31 emit or sense at least one of ultrasonic waves, lasers, infrared rays, and reflected waves toward the front of the screen 11 (b).

The ultrasonic proximity sensors 30 and 31 use the characteristics of ultrasonic sound, which is a sound with a high frequency (about 20 KHz or more) that is inaudible to the human ear, and can be used in air or liquid. Since the ultrasonic waves of the ultrasonic proximity sensors 30 and 31 have a high frequency and a short wavelength, they can be measured with high resolution. The laser proximity sensors 30 and 31 are also called lidar, and by reflecting a laser beam on a high-speed rotating mirror and scanning the dispersion, the positions and trajectories of countless objects are observed simultaneously. Specifically, after measuring the horizontal angle, vertical angle, and slope distance to the target, a post-processing method is performed by a predetermined numerical analysis to determine the location and trajectory of the target.

When the infrared proximity sensors 30 and 31 emit infrared rays (b), the maximum response to the user's temperature of 36.5° C. is reflected, and returns to the proximity sensors 30 and 31 . The wavelength that responds maximally to the user's temperature of 36.5°C is infrared of about 9.36㎛. By utilizing infrared rays, it is possible to prevent objects other than the user from being detected. Specifically, the infrared proximity sensors 30 and 31 measure the speed of the infrared wavelength, the emission and reflection time, and numerical analysis, so that the user's location and trajectory can be confirmed. The image proximity sensors 30 and 31 receive light from the target and confirm the location and trajectory of the target. The image proximity sensors 30 and 31 measure the horizontal angle, the vertical angle, and the slope distance to the target by the reflected wave, and then determine the position and the trajectory of the target through numerical analysis.

An example of a game applied to an embodiment of the present invention will be described in detail. One of the above games is a ball game. For example, soccer is projected onto the screen 11 with a goalpost and goalkeeper as images, and users play soccer. The game device of the present invention grasps the position and trajectory of a soccer ball, which is a user and a playground equipment. When the user shoots toward the screen 11, the proximity sensors 30 and 31 grasp the position and trajectory of the moving soccer ball, and the control unit 13 controls the goalkeeper image of the screen 11 to block the soccer ball. make it move Whether the soccer ball is a goal is checked by the touch sensor 20 . If the soccer ball touches a place where there is no goalkeeper image, it is a goal, and if it touches a place with the image, it is not a goal. The sports can be variously expanded to baseball, basketball, and the like.

Also, another one of the above games is a balloon pop game. Specifically, an image of a moving balloon appears on the screen 11 , and when the user touches the balloon image of the screen 11 , the image is converted into an image of a balloon popping. The proximity sensors 30 and 31 determine the location and trajectory of the user, and the touch sensor 20 confirms which user touched the balloon image. The game can be expanded in various ways, such as catching fish. In other words, the game according to the embodiment of the present invention can be implemented by a combination of the touch sensor 20 and the proximity sensors (30, 31).

The projector 40 is positioned at a horizontal distance L and a vertical height H with respect to the center c of the screen 11 . The horizontal distance L and the vertical height H are set so that the image is clearly expressed on the screen 11 . The horizontal distance L and the vertical height H are set in advance in consideration of the type, function, size, shape of the screen 11, and the like of the projector 40 . Since the horizontal distance L and the vertical height H are already known, a detailed description thereof will be omitted. The projector 40 may be connected to a cable 41 extending from a ceiling of a building or the like. The cable 41 applies power, a signal, and the like to the projector 40 .

In some cases, the projector 40 may be equipped with a proximity sensor 32 in the projector. The proximity sensor 32 in the projector is distinguished from the proximity sensors 30 and 31 in the screen. Since the proximity sensor 32 is arranged in three dimensions through connection with the proximity sensors 30 and 31 on the screen, it is possible to more precisely measure the position and trajectory of the target.

The first game device 100 according to the embodiment of the present invention combines the process of confirming the location and trajectory of the target in front of the screen 11 in addition to the game operation by the touch of the screen 11, can be actively operated. Active means that the position, trajectory, and touch of the target are interconnected, and the game image is converted according to the motion of the target. For example, the position of the goalkeeper is changed according to the movement of the user in the soccer game, and the position of the balloon is changed according to the movement of the user in the balloon popping. Since the game image is changed and displayed on the screen 11 , the screen 11 of the present invention is an active screen 11 .

2 is a schematic diagram for explaining the second game device 200 according to an embodiment of the present invention. The second game device 200 is the same as the first game device 100 , except that a positioning unit 50 is added. Accordingly, detailed descriptions of the same reference numerals will be omitted.

Referring to FIG. 2 , the positioning unit 50 of the second game device 200 may use various methods such as a mechanical method, an optical method, and the like. Here, the mechanical method is presented as an example. The positioning part 50 includes a pin receiving part 51 , a positioning pin 52 and a probe 53 . The pin receiving part 51 allows the positioning pin 52 to move up and down while fixing the positioning pin 52 . The probe 53 has a pointed shape and is in contact with the position point P marked on the floor of the game room. The position point P is set in advance to be suitable for a game by the second game device 200 . The position point P is determined in consideration of the relationship between the projector 40 and the screen 11 .

If the position of the second game device 200 is designated using the position point P, the positions of the screen 11 and the projector 40 can be easily determined. Without the positioning point P and the positioning unit 50, it takes a lot of time to determine the position of the screen 11 with respect to the projector 40 before starting the game. The positioning method according to an embodiment of the present invention can greatly reduce the waste of time and facilitate the operation of the game. For example, when not playing a game, the remaining part of the second game device 200 except for the projector 40 is moved out of the game room, and the remaining part is moved using the position point P before starting the game. can

As mentioned above, although the present invention has been described in detail with reference to preferred embodiments, the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the scope of the technical spirit of the present invention. possible.
