AREA of TECHNOLOGY

The invention relates to the management of interactive lighting, specifically to the management and creation of lighting effects, such as regulation of light scenes based on the indication of the location received from the input device, and more particularly to a system and method of managing an interactive lighting to control and create light effects with the use of display device location.

PREREQUISITES

Modern professional environment and the home environment of the future should contain a large number of light sources of different nature and type: incandescent, halogen, discharge lamps or lamps based on LED (light emitting diode) for ambient, ambient, accent or working light. Each light source has different management capabilities, such as dimmable, cool/warm lighting, RGB or other methods that change the effect of light source on Wednesday.

Almost all of the management paradigm in lighting based on the lighting operation: the user selects the lamp and acts directly on the control unit of the lamp by changing the value of a blackout or acts on RGB (red, green, blue) channels of the lamp. At the same time can be very natural to adjust the lighting effect directly�in public location and don't bother searching for lamps, they are responsible for the effect in a certain location.

When the number of light sources is more than 20, can be challenging returning to track the effect of a light source provided at the location. Furthermore, the effect may be the result of a combination of different lighting effects from light sources of different nature (for example, lamps Ambient TL (working light) and LED lamps surrounding the lighting of the walls). In this case, the user should experiment with various lighting control lamps and to evaluate the effect of their changes. In some cases, this effect is more global (e.g., ambient light), in some cases, this effect is very local (e.g., point light). Therefore, the user has to figure out what the control unit is connected with one or another effect, and it is necessary to clarify the effect size in order to approach the desired light settings.

Summary of the INVENTION

The purpose of the invention is to improve the management of infrastructure lighting.

Goal is achieved by the subject invention according to the independent claims. Additional implementation options are presented in dependent claims.

The basic idea of the invention is a member, to provide control of the interactive lighting by combining display device location with controlled lighting effect approach to control of lighting in order to improve the creation of lighting effects, such as regulation of light scenes, in particular, in large and heterogeneous infrastructure lighting. Managed effect approach to control of lighting can be implemented by using a computer model that contains a virtual representation of a real environment with the lighting infrastructure. Virtual views can be used to project a real location to a virtual location in the virtual environment. The lighting effects available in the real location, you can detect and simulate in virtual form. While virtual location and available light effects can be used to display lighting effects to the user for selection, and to calculate the control settings for the lighting infrastructure.

DESCRIPTION of embodiments of

In the future, functionally similar or identical elements may have the same item numbers. The terms "lamp", "light" and "light source" describe the same thing.

Fig.1 shows a control system of interactive lighting 10 that contains the interface 12, for example, the wireless transceiver adapted to wirelessly receive data from the input device 18, the controller light effects 20, shaper lighting effects 22 and the video processing unit 26 for processing video data captured by the camera 24, which is connected with the system of interactive lighting 10. The control system of interactive lighting 10 is provided for controlling the lighting infrastructure 34 containing several lamps 36 installed in the actual fry�e, like the room with the wall 30. The system 10 can be implemented by a computer executing software that implements the modules 20, 22 and 26 of the system 10. Then the interface 12 may be, for example, Bluetooth™ or Wi-Fi computer. The system 10 may be further connected with a display device 28, such as a computer monitor or TV.

Interactive lighting control created using the infrastructure of lighting 34, can be done by using the input device 18, which can keep the user 38. The user 38 who wants to create a certain lighting effect in real location 16 on the wall 30, just pointing input device 18 to the location 16. To detect the location 16, which shows the user 38, the input device 18 is adapted to the detection of the location 16.

The input device 18 may be, for example, the intuitive pointer uWand™ and three-dimensional control device from the applicant. The control device uWand™ contains the IR (infrared) receiver that detects signals from coded IR beacons, which can be located on the wall 30 in addition to the TV. From the received signals and the positions of the beacons, the control device uWand™ can get it half�proposal instructions and to transmit the received position indication via a wireless 2.4 GHz communication channel interface 12. The control device uWand™ makes possible the detection of two-dimensional and three-dimensional position. For example, can also occur detection of rotation of the input device.

For the purposes of the present invention it is also possible to use the input device WiiMote™ of Nintendo Co., Ltd. The input device WiiMote™ makes it possible to detect two-dimensional position indication by means of capturing the IR radiation from the IR LED built-in camera and receiving the position indication from the detected position of the infrared LED. Transmission-related data detected by the position specifying occur via a Bluetooth™, for example, using the interface 12.

In addition, as the input device, you can use a laser pointer or light the lantern when it is combined with a camera to detect the position of the instructions in a real environment, for example, on the wall 30. The data associated with the detected position indications generated by processing image data captured by the camera. The camera can be embedded in the input device, similar to the input device WiiMote™. Alternatively, a camera can be an external device, combined with a block of video processing to detect the position of the instructions. An external device that contains a camera, or may be connected to the control system interact�VNOM lighting 10 or integrated into it, for example, the camera 24 and the video processing unit 26 of the system 10.

The input device 18 wirelessly transmits data 14, reflecting the location 16 to which it points in a real environment 30, the interface 12 of the control system of interactive lighting 10.

Controller lighting effects 20 of the control system of interactive lighting 10 processes the received data 14 as follows: actual position location 16 is converted to a virtual location of the virtual species in a real environment. The virtual view may represent a two-dimensional representation of a real environment, such as wall 30 shown in Fig.1. The virtual view may be generated, for example, by means of capturing the real environment using the camera 24. Also, the virtual view may already be stored in the control system of interactive lighting 10, for example, by obtaining the image of the wall 30 using a digital camera and transfer the obtained image to the system 10.

Controller lighting effects 20 determines the lighting effects available in the virtual location. This can be accomplished, for example, by a model infrastructure lighting 34 installed in a live environment, where the model connects the device management infrastructure light 34 with light effects and locations in�realnom real environment.

You can create a model of the so-called method of calibration in a dark room (DRC), which measure the effect and the location of each control device, the lighting DMX channels. Then, the lighting effects are detectable using DRC, you can assign virtual locations in a virtual form, to generate a model. For example, the distribution of the target illumination can be expressed in the form of the target set at discrete points, for example, 500 Lux at certain points of the working surface, in the form of colorful propagation in two-dimensional form, for example, distribution, measured on a wall, or spread, which is attended by the camera or colorimetric device, or, more abstractly, as a function that associates light effect with a location.

The lighting effects, which is determined by the controller light effects 20 as available at the location 16 can be displayed on the display device 28 or transmit through the interface 12 to the input device 18 or a separate input device lighting effects 40, which may be, for example, implemented, for example, via a PDA (personal digital assistant), smartphone, keyboard, PC (personal computer), the remote control, such as TV.

Custom �selecting the desired lighting effect is passed from the input device 18 or the input device lighting effects 40 system 10 via the interface controller 12 light effects 20, that transmits selected light effect and the location of the 16 shaper lighting effects 22. The imaging unit 22 monitors the lamp 36 infrastructure lighting 34, which affect the light at the location 16, calculates the control settings for tracked lamps 36 and transmits the calculated control settings lighting infrastructure 34 so that at the location 16 to create the desired user effect light by lamps 32 36.

The following points explain the user selecting 38 lighting effects with just a few usage scenarios. In the presented scenarios, the cross denotes the position specifying input device 18, and the dashed arrows represent movements performed with the input device 18, i.e. the movement of the location of the instructions of the input device 18 from one location to another in a virtual form, which is a two-dimensional representation of a real environment, for example, the walls 30.

Fig.2-7 presents some possible interactions between the input device 18 and effects present in virtual form. Because the contents of the virtual view can be considered as the target distribution of light effects, the issuance of illumination can vary accordingly so that the user 38 can receive immediate feedback. This can apply to�lead to immersive subtle regulation of the atmosphere lighting created by lighting infrastructure 34.

Fig.2 presents a scenario where the lighting effect is selected in one location 161 and drag to another location 162. The desired lighting effect, such as a spot light, is in the first location 161. The user 38 may select the desired lighting effect by specifying the input device 18 to the location 161 and clicking on a certain button of the input device 18 and drag the chosen light effect to a new location 162, where it needs to be created. In its new location 162, placed a cross, 38 user releases still pressed button or presses the button again. The input device 18 may record the location 161 when clicking the first button and 162 location when you release the pressed button or you press the second button and pass both locations 161 and 162 as the data reflecting the actual location, along with data associated with the light effect, that is, dragging light effect on location 161 162 to a location in the system 10, which then creates a spot light location 161 in its new location 162. This technical process for detecting user interaction to select the desired lighting effect for location and transmission� data associated with this choice, also carried out with the following usage scenarios described below.

Fig.3 presents a use case where light effect, such as the spot of light created by the lamp, allowing a redirect or movable head at location 161 select and drag to another location 162. Interaction the same way as described in relation to the usage scenario shown in Fig.2. In this scenario, use may be easier to put light effect exactly at the desired user to the new location 162.

Fig.4 presents a use case of the virtual functions in the form to expand interaction. In some cases it is necessary to create a more complex task lighting (such as gradients). In this case the green effect 163 can be inserted in a gradient from red to blue 164. Location green effect affects the formation of the transition red- > green and green- > blue. The location of the green spots can be changed using the described interaction drag and drop. In General, functions (such as creating a gradient) can be implemented as such that it is possible to provide a richer interaction with the lighting system. Then, these functions respond to the location of the lighting effects in order to�to give a more complex interaction.

Fig.5 shows a scenario to use with the points of attraction location 165. Since the system 10 knows the location effects and maximums effects, it can use these location 165 as "points of attraction effects". When dragging light effect 166 he will jump from point of attraction to the point of attraction. This simplifies for the user the location of the effect, since the effects are placed only in the appropriate places. Also this extends the immersive feedback to the user, because the location can follow the change of the illumination. The definition points of attraction is not limited to maximum effect; also relevant may be sensitive input functions.

Fig.6 and 7 presents additional usage scenarios, combining a display device with a color palette 167. As described in relation to Fig.1, in a real environment may be a display device 28, which can display the color palette 167 lighting effects. Palette and location on the screen can be operated by a control system of interactive lighting 10. The location of the display device 28 can be embedded in a virtual form. Indicating the 168 color palette 167 on the display device 28 may be �narozena virtual, and there is no difference between the color drop on the display device and lighting effect. It makes possible the interaction that is similar to the usage scenario shown in Fig.2 and explained above: select an effect and drag it to another location. The color effect of drag from the display device in the environment, as if it was a lighting effect. Instead of a display device with a static color palette it may also be a display device with some dynamic content, as shown in Fig.7. Dynamic content can contain multiple 169 pixels, and each pixel can vary with time. The pixels in the dynamic content can also be converted into points of attraction of the location in the virtual view. Instead of a single display device the color palette and the target color can also be displayed and selected on the input device 18 or the input device lighting effect 40.

When pointing to the location that the display device can give some feedback on opportunities in these locations. For example, a triangle of colors that can be traced in that location may be displayed on the input device or a separate display device.

When there are multiple effects, control system �online lighting 10 can choose the most influencing effect at the location, in which the user must specify. You can also affect the range of effects.

Finally, as in the well-known interaction with mouse and pointer, the user 38 may also specify the area in virtual form. Thus, choosing a set of effects, which are mainly present in a certain area. Then carry out adjustment operations for a set of effects.

Adjustment operations possible in the selected area can be, for example,

changing the color temperature, hue, saturation and intensity.

smoothing or sharpening effects: weaken or intensify the limit values of the hue/saturation/intensity.

To reflect the size of the selected area, lamps that create a contribution in a specific area, you may begin to flash, or can be configured through the control system of interactive lighting 10 on a contrasting light effect. It provides the user with 38 feedback in the selected area.

The input device 18 can be used several ways of interaction for changing light effect:

Buttons for changing hue, saturation and intensity (set) effect(s) on which you specify.

These settings can also be changed by moving the input device 18 up or down and through�your use of acceleration sensors for detecting this movement.

Buttons or other input methods can be used to implement the operation "drag" (to move effects or to select the area).

Circle color sensitive touch screen or other arrangement that shows the hue, saturation and intensity of the specified lighting effect and which allows you to bring the hue, saturation and intensity to a value that satisfies the user.

When choosing the area shown values of hue, saturation and intensity may represent averages and minimums and maximums. In the latter case, the interaction makes it possible to change the extreme values. It is also possible to weaken or strengthen the distribution of extreme values in order to smooth or sharpen effect.

The invention can be used in environments where there is a large number, for example, more than 20 light sources in homes of the future with a complex and heterogeneous infrastructure lighting in shops, public spaces, lobbies, create lighting scenes, for chains of shops (you can come up with a single reference store where lighting scenes are created for all stores; when light scenes unfold, it may take some fine control). The interaction also can be used�to olisivat for adjusting the location of the spot, allowing for the redirection. These spots are mainly used in stores (mannequins), art galleries, theaters and concert venues.

Typical applications of the invention are, for example, in the creation of light scenes in an empty place (place area and intensify the effects from zero to the desired value) and immersive subtle regulation of light scenes, which are created using other methods of generation.

At least some functionality of the invention can be implemented using hardware or software. In the case of implementation in software you can use one or multiple standard microprocessors or microcontrollers for processing one or more algorithms that implement the invention.
