Description

Interactive projection device images.

Object of the invention

The present invention relates to a interactive imaging device so that at to capture some movement over an active detection zone, corresponding to the projection, occur in said projection changes according to animated images according to the movements detected.

Background of the invention

The Spanish utility model is known U200200198 by Mr. Manuel Gómez del Prado for "Advertising poster with cadential images "in which a poster is described consisting of a white vertical surface and a projector duly placed in its upper anterior part for the projection of computer generated images, of character advertising This poster allows the administrator of the device can transmit telematically to the computer the images of posters and advertisements to reproduce, but does not present No degree of interactivity.

The utility model is also known U124540 by D. Jaime Rumbao Franco for "Portable projector for advertising "in which a device with a body is described inside which there is a light bulb, a frame and a game of lenses that allow the projection of the image of the frame against various surfaces, thus being able to observe the frame With a noticeably larger size.

In addition, promotional devices are known consisting of figures of certain dimensions or exhibitors comprising means for detecting the passage of people. These systems are arranged in streets or corridors of large warehouses so that when a person passes within their field of  Capture activates a recording with an advertising message and / or musical intended to draw attention to the device and the advertising or product offered.

Description of the invention

The interactive projection device of images of this invention presents some technical peculiarities intended to achieve an attractive effect, in which the user or passerby is an active part of the projected motive through its interaction, simulating an entry in a virtual environment.

This device can be used to attract the attention of the public and clients in different events and scenarios, since this projection effect is interactive. With the device it is sought to project in a floor area preferably, an image or animation that recreates an environment concrete, so that when passing objects or subjects through said environment the image or animation is modified according to some effects determined and the position and movement of the subject or subjects detected.

In fact, the device comprises at least one motion and position sensor associated with a calculation computer and image generation. With sensor capture the computer you can determine the entry of at least one object or subject in the area on which the image is projected and the modification of said real-time image or partially through images Presynthesized This modified image or animation is projected again creating an interactive and immersion effect of the object or subject in a virtual environment.

The motion and position sensor is preferably a video camera with a filter infrared

To improve sensor uptake, You can light the stage with one or more spotlights infrared oriented towards the projection zone.

To achieve a more impactful effect it has been provided that the device comprises a reproductive means of Sound connected to the computer. In this way when detects a movement not only the stage aspect is changed by changing the projected image or animation, but You can also make sounds consistent with the effect wanted.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, with character Illustrative and not limiting, the following has been represented:

- Figure 1 shows a schematic view Of the device.

- Figure 2 shows an example of the image projected with an area modified by the presence of a subject in movement that creates an aura around it.

Figure 3 shows a schematic view of the device with the motion sensor separated from the projector on opposite positions.

Preferred Embodiment of the Invention

The present device, represented in the Figure 1, comprises a motion and position sensor (1), specifically a camera with an infrared filter and next to a projector (2), both perpendicular to the ground plane and centered at  certain height with respect to the area of projection-uptake (3) for better sensitivity and visibility without distortion of the animations.

The sensor (1) and the projector (2) are connected in turn to a computer (4), which will preferably be a Standard PC that is responsible for performing data analysis sent by the motion and position sensor (1), and of generating the  projected image (31) and animations (32) that shows the projector (2) to the subject (8) when it enters the zone (3).

The connection between the sensor (1), the projector (2) and the computer (4) will preferably be wired (5), if either the constituent chamber of the sensor (1) connect so wireless Around or next to the sensor (1) there will be a focus (6) infrared lighting, such as an LED diode ring infrared, oriented to illuminate the area of projection-capture (3) correctly before the possibility of low infrared lighting.

The computer (4) is also connected with sound reproducing means (7), such as speakers, for the generation of sounds and sound effects combined with projected animation effects.

The device can be placed in other non-optimal conditions, such as the one shown in figure 3, in which the motion sensor (1) and the projector (2) are in different remote side positions, which makes both projection as the detection are not optimal but viable.

Some of the effects that can be recreated with This device are:

Pond effect: This effect consists of creating a animation that simulates a pond in which there may or may not be objects moving. In the case of objects, they will move from autonomously at a configurable speed. The user, when passing through the area sensitive to movement, generates the effect of the waves that a person would create when stepping on an area with water. If that objects have been included in the effect, they will flee the person, for example. You can also reproduce an effect of sound.

Particle Effect: This effect consists of the creation of a fund on which there is a certain number and configurable objects (such as sheets) distributed in a way random When motion is detected in an area, the objects that in that area they will be repelled from the movement zone, leaving Uncovered a background image. After a certain time configurable after cessation of movement, objects will return to its initial position.

Appearance effect: This effect consists of creation of a fund on which objects are generated or appear (which can rotate or not) where motion is detected. So by For example, a field of grass on the ground can be arranged Let daisies appear that rotate on themselves. These objects generated disappear after a while, selected by the user, no movement detected. The configurable options of effect are:

Transparency effect: This effect consists of creation of an image in the foreground and another in the background, of so that in the area where movement is detected the image that is in the foreground, looking at the one in the background flat. After a certain configurable time without detecting movement,  the uncovered areas will be covered.

Once nature is sufficiently described of the invention, as well as, a preferred embodiment example, is for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential characteristics of the invention that are claimed by continuation.
