The disadvantage of this device is the relatively small class of video effects, due to the fact that the generated video image does not respond to the movement of any disturbing object in it.

A device for creating video images is also known (RF patent No. 2095682 from 10.11.2006, classes F 21 P 5/02, G 02 B 27/00, A 63 J 15/00, A 63 J 17/00, http: // www. fips.ru), which contains a laser, two mirrors, a power source, a control unit, an elastic flexible element.

The disadvantage of this device is also a relatively small class of video effects, since the generated video image does not respond to the movement of any disturbing object in it, in addition, the relatively high cost of its implementation is also a disadvantage.

The closest in its technical essence to the claimed one is the device (Global Interactive Complex) according to the application No. 2004128746, dated 10.03.2006, class A 63 J 23/00, http://www.fips.ru.

The prototype device consists of N> = 1 screens, N projectors, a projector control unit, that is, an effect control unit (implemented as a projection control unit), N individual software control units, N terminal devices and an acoustic system.

With such a combination of features in the closest analogue compared to the known devices discussed above, the formation of the interactivity function of the projected image is ensured, which somewhat increases the entertainment of advertising and entertainment events.

The disadvantage of the prototype device is the limited scope, since the possible variants of the formation of effects are generated only on the basis of the fact that the brightness of the light flux changes when the disturbing object enters the projected image, while the characteristic features of the disturbing object are not taken into account, which limits the options for generating interactive effects.

The purpose of the claimed utility model is to develop a device for creating interactive effects, providing an extension of its field of application, due to the possibility of forming interactive effects generated on the basis of both the fact of changing the brightness of the light flux when the disturbing object enters the projected image, and based on the individual characteristics of the disturbing object .

Thanks to the new set of essential features in the claimed device, due to the formation of the identification (recognition) function, automatic adaptive control of interactive effects is provided, which allows expanding the classes of interactive effects, thereby achieving the possibility of using the claimed technical solution at children's parties, youth discos, sports shows, presentations , exhibitions, conferences, that is, to expand the scope of the claimed object.

The device operates as follows.

In accordance with the signals received from the effect control unit 4i, the projector 2i projects a video image onto a predetermined surface 1i.

When a disturbing object appears (as a disturbing object, it is considered here: a person, a pet, any object that causes a change in the brightness of the light flux) within the projected image, the following signals appear at the outputs of the coordinate determination and identification unit 3i:

- at the coordinate outputs x, a code combination corresponding to the x coordinate of the disturbing object appears;

- a code combination appears on the coordinate outputs y corresponding to the y coordinate of the disturbing object;

- a code combination appears on the identification outputs corresponding to the identification image of the disturbing object.

The identification image of the disturbing object is formed based on the features of its silhouette. This may be a set of linear dimensions in various sections. For example, an identification image in relation to a person may consist of a set of the following

parameters: height L1, face size full-face L2, shoulder width L3, hip width L4 (see Fig. 5 a, b, c).

Options for the formation of identification images can be different. For example, the use of photographs of a disturbing object taken in advance from a certain angle.

The code combination corresponding to the x coordinate of the disturbing object is supplied to the coordinate input x of the video effects generator 4.1i and the coordinate input x of the audio effects generator 4.2i. The code combination corresponding to the y coordinate of the disturbing object is supplied to the coordinate input y of the video effects generator 4.1i and the coordinate input y of the audio effects generator 4.2i. The code combination corresponding to the identification image is input to the identification input of the video effects generator 4.1i and the identification input of the audio effects generator 4.2i.

The video effects generator 4.1i, in accordance with the accepted code combinations corresponding to the x, y coordinate and the code pattern of the identification image, according to the specified algorithm (see Figure 4) generates a sequence of pixels of the video image illumination, which come from its output to the input of the projector 2i, forming most video effects in accordance with the location of the disturbing object within the projected image and its identification image.

At the same time, in accordance with the accepted code combinations corresponding to the x, y coordinate and the code pattern of the identification image, the 4.2ii-4.2.3i ROMs of the audio effects generator 4.2i generate code combinations that are transmitted to the DAC 4.2.4i-4.2.6i to the input of the adder 4.2.7i, the output of which is output to the speakers 5i, generating sound effects in accordance with the location of the disturbing object within the projected image and its identification image.

So, for example, in the formation of such an interactive effect as a “train of figures”, in the case of the appearance of a disturbing object in the form of a man, it will consist of dark circles (see Fig. 6a), in the case of a woman - from stars (see Fig. 6b ), in the case of the appearance of a child, from snowmen (see Fig.6c).

Or, for example, when children enter the projected video image, the latter is supplemented by elements depicting their favorite animal (see Fig. 7a, b).

As a result, the projected image and the accompanying sound effects are determined both by the spatial location of the disturbing object within the projected image, and by its identification image.

Thus, when using the claimed utility model, it is possible to generate interactive effects not only on the basis of the fact of changing the brightness of the projected video image caused by the presence of a disturbing object within it, but also taking into account the individual characteristics of this object, which makes it possible to significantly increase the number of interactive effects, their adaptation to the conditions of the event (concert, presentation, children's party, etc.) that is, it expands the scope of the claimed triplets. The aforementioned indicates the feasibility of the formulated technical result when using a utility model.
