This invention pertains to the field of motion pictures; especially it is concerned with techniques and equipments that produce olfactory and tactual effects in existing motion pictures that are based on traditional visual and auditory effects. Boasting of a breakthrough in modern cinematographic art that is dominated by traditional visual-auditory effects, this invention designs to display a quadrate effect that makes use of the four human senses during film-watching: viewing, hearing, smelling, and touching.
Nowadays, watching films has become an indispensable part in people's life. In addition to bringing enjoyment and amusement to people's life, motion pictures are providing large quantities of knowledge and information to moviegoers. It is obvious that modern movie industry attaches great importance to the enhancement of visual-auditory effects in motion pictures. On the other hand, it is also apparent that humans obtain knowledge and information not only through the senses of viewing and hearing but also through the senses of touching, smelling, and tasting. Keeping people enjoying their favorite films only by using the two senses of viewing and hearing will greatly restrict people's enjoyment of such films, which are also regarded as one form of culture and art.
It is widely-known that modern movies are capable of providing large numbers of visual and auditory effects to audiences. Unfortunately there has never been a film in existence that can also produce olfactory and tactual effects. The main difficulties for doing that are: (1) odors are chemical substances whose components are so complex that they cannot be created simply by combining a few chemical elements together; and at present, there are very few electronic sensors that can convert odors to electronic signals. As a result, no equipment has ever been invented that can receive or transmit olfactory signals during the process of producing or projecting a film. (2) Tactual effects are even more difficult and complicated to produce or simulate in motion pictures.
With the development of modern cinematographic art, people have already realized the importance of producing olfactory and tactual effects in motion pictures. On the other hand, however, no practical designs have ever been invented that are capable of producing olfactory and tactual effects in motion pictures so that the quadrate effect of viewing, hearing, smelling and touching can be experienced during film-watching.
This invention will provide details on techniques and corresponding equipments that can produce olfactory and tactual effects in motion pictures. The purpose of the said invention is to enable existing motion pictures to generate olfactory and tactual effects in synch with the physical phenomena in film screen, such as emitting different odors, wind-blowing, raining, sneezing, shaking, bumping, and so on. As a result, the simultaneous activation of the four human senses of viewing, hearing, smelling, and touching will definitely place audiences on the scene of the film, thus further enhancing the entertaining effect of the film.
In order to accomplish the above purposes, this invention designs a technical scenario that is capable of producing olfactory and tactual effects in motion pictures. The details are described as follows:
1. In accordance with the plots of the film, olfactory and tactual signals that work in concert with visual and auditory signals will be designed; and the default signal system for the olfactory and tactual signals will be one of these: digital, analog, optical, or magnetic. Olfactory signals will be released according to the types of the targeted odors, and tactual signals will include at least one of the following signals:
2. One of the following two techniques will be chosen for the production of olfactory and tactual signals:
3. During the process of film projection, olfactory and tactual signals are released in synchronization with the development of the plots of the film. Specifically, after being detected by a detection circuit, olfactory signals activate a set of control units by means of a control circuit. The set of control units then forces odors into their corresponding pipes while activating the odor exits located around audiences where odors that correspond to the pictures and sounds in the film are sent off.
Similarly, upon being detected by the detection circuit, tactual signals activate a set of control units and trigger the corresponding tactual simulation devices located around audiences, producing simulated tactual effects that synchronize with the corresponding pictures and sounds in the film. The devices that produce simulated tactual effects will include at least one of the following:
Specific details of the technical scenario for the production of the two signals are described as follows:
1. In the above technical scenario, at least two different types of odors in the following categories will be included:
Flower fragrance, perfume scent, coffee smell, cooking odor, fruit smell, the smell of sourness, spiciness, funkiness, the smell of raw meat or fish, smoking smell, the smell of gun powder and fresh air.
2. In the above technical scenario, odors can be stored either in a liquefied state or in an air-compressed state. When the odor is stored in a liquefied state, it can be evaporated by heating and released through an air pipe before being emitted into the air by way of the odor exits (No air compressor is necessary for the emitting of the odor, which actually can be released by controlling the electromagnetic valve in an odor tank); or odors can be released using pressurized spraying technique and then are emitted into the air through odor exits (In this case, air compressor is necessary for the releasing of odors in the form of fogs).
When odors are stored in an air-compressed state, they can be released into the air pipe through a valve before being emitted into the air by way of the odor exits (In this case, no air compressor is necessary for the emitting of odors, which actually can be released by controlling the electromagnetic valve in the odor tank); or the pressurized odors can be stored in a pressure tank, and, controlled by the odor-emitting signal, be emitted into the air pipe until they are finally released into the air through air/odor exits.
3. In the above scenario, the strength to which the targeted odor is smelled by audiences can be regulated by controlling the length of time used to keep the odor exits open as well as by controlling the size of the odor exits' apertures. The strengths of wind-blowing and raining can also be regulated by controlling the length of time used to keep the wind-blowing exits and the sprinkler heads open as well as by controlling the size of the apertures of the wind-blowing exits and of the sprinkler heads.
4. In the above scenario, tactual effects can be generated by triggering tactual simulation devices installed around audiences. Specifically:
5. In the above scenario, there are two means to produce olfactory and tactual effects. One means is to combine the olfactory and tactual effects in the film with its visual and auditory effects. In this case, during film projection, motion-picture projector or DVD player produces olfactory and tactual signals in synch with the development of the film plots (These signals can be programmed during the process of making digital films). For best effects, the olfactory and tactual signals can be processed and transmitted by the use of multi-channel digital projectors.
The other means to produce olfactory and tactual effects in a film is to generate olfactory and tactual signals using simulation program. In this case, these signals are independent of the film's visual and auditory signals. The simulation program used for producing olfactory and tactual signals is not linked to the film projector. When the film is being projected, a special device is used for producing olfactory and tactual signals in synch with the development of the film plots. This type of isolated simulation program can be combined with any types of film projectors, and can be used for producing olfactory and tactual effects in any films;
6. In the above scenario, after odors are produced inside the cinema, fresh air can be sent into the air pipe to clear the odors. In addition, central air conditioning system installed in the cinema can also be used to refresh the air around the audiences. Installing separate devices to ventilate the cinema is also a good choice;
7. In the above scenario, fresh air contained in an odor tank can be used to produce natural wind, and it can also be used to refresh the air in the cinema.
In order to achieve the above-mentioned purposes, this invention designs a technical scenario that is capable of generating olfactory and tactual effects. This scenario consists of olfactory- and tactual-simulation devices, which include the following:
The details of above technical scenario are provided as follows:
1. Locations where the multi-functional emission boxes are installed:

2. Process of Simulating Wind-Blowing Effect
3. Process of Simulating Raining Effect

5. Process of Simulating Shaking and Bumping Effects
Due to the employment of the above technical scenario, this invention is characteristic of the following advantages:
Diagram 1 is the schematic diagram of this invention;
Diagram 2 is the layout schematic drawing of this invention that illustrates where devices that produce olfactory and tactual effects in films are installed in the cinema;

In the above diagrams,
The detailing of this invention based on diagrams will be provided by using the following examples:
This example illustrates one technique of producing olfactory and tactual effects. as Diagram 1. The details are as follows:
1. Based on the plots of the film, olfactory and tactual signals that work in concert with visual and auditory signals will be designed, and the default signal system for producing the olfactory and tactual signals will be digital signal system. Specifically, the release of olfactory signals is based on the types of the targeted odors, and tactual signals will include at least one of the following signals: 1) signals that simulate wind-blowing, 2) signals that simulate raining, 3) signals that simulate sneezing, 4) signals that simulate shaking, and 5) signals that simulate bumping.
2. Olfactory and tactual signals are produced in combination with the visual and auditory signals of the film. During film projection, the projector or DVD player produces olfactory and tactual signals in synch with the development of the film plots. These signals can be programmed during the process of making digital films, and the olfactory and tactual signals can be detected and transmitted by means of multi-channel devices in digital film projectors.
3. During film projection, olfactory and tactual signals are released in synchronization with the development of the plots of the film. Specifically, as soon as they are detected by the detection circuit, the olfactory signals activate a set of control system components via the control circuit, which releases odor into air pipes and activates odor exits. Then odors that correspond to the pictures of sounds in the film are released into the air via odor exits located around the audiences.
After being detected by the detection circuits, the tactual signals activate a set of control system components by means of the control circuit, which triggers the corresponding tactual-effect-simulation devices located around the audiences, thus producing simulated tactual effects that correspond to the pictures and sounds in the film. The simulated tactual effects will include at least one of the following devices: 1) device that simulates wind-blowing, 2) device that simulates raining, 3) device that simulates sneezing, and 4) device that simulate shaking and bumping.
In terms of simulation of olfactory effects, at least two odors in the following categories will be included: flower fragrance, perfume scent, coffee smell, cooking odor, fruit smell, sourness, spiciness, funkiness, the smell of raw meat or fish, smoking smell, the smell of gun powder and fresh air.
Odors can be stored either in a liquefied state or in an air-compressed state. When the odor is stored in a liquefied state, it can be evaporated by heating and released through an air pipe before being emitted into the air by way of the odor exits (No air compressor is necessary for the emitting of the odor, which actually can be released by controlling the electromagnetic valve in an odor tank); or odors can be released using pressurized spraying technique and then are emitted into the air through odor exits (In this case, air compressor is necessary for the releasing of odors in the form of fogs).
When odors are stored in an air-compressed state, they can be released into the air pipe through a valve before being emitted into the air by way of the odor exits (In this case, no air compressor is necessary for the emitting of odors, which actually can be released by controlling the electromagnetic valve in the odor tank).
The strength to which the targeted odor is smelled by audiences can be regulated by controlling the length of time used to keep the odor exits open as well as by controlling the size of the odor exit's apertures. The strengths of wind-blowing and raining can also be regulated by controlling the length of time used to keep the wind-blowing exits and the sprinkler heads open as well as by controlling the size of the apertures of the wind-blowing exits and of the sprinkler heads.
Tactual effects can be generated by triggering tactual simulation devices installed around audiences. Specifically:
This is a device that produces olfactory and tactual effects in motion pictures. Functionally speaking, this device is made up of devices that can simulate the effects of wind-blowing, raining, sneezing, shaking, and bumping. The device consists of the following parts:
1. A set of odor tanks and corresponding air pipes; and each odor tank contains different odors;
2. Water pipes, pumps, or tap water;
3. Multi-functional emission boxes, which are installed around the seats in the cinema. Each box contains an odor-emitting device, a wind-blowing simulation device, and a raining simulation device. Specifically:
4. A servo electromagnetic vibrator, a servo hydraulic vibrator and their corresponding control system components. The servo electromagnetic vibrator and the servo hydraulic vibrator are installed on the underside of the seat to produce the effects of shaking and bumping;
5. Control device and drive circuit. The control device is a control circuit or a control module with a CPU processor. The input terminal of the control circuit or the control module receives the olfactory and tactual signals generated in synch with the development of the film plots. The output terminal connects to the control terminal of the drive circuit of each control system component. Each drive circuit connects to its corresponding control system components.
Diagram 2 is the layout schematic drawing that illustrates where devices for odor-producing, wind-blowing-simulating, raining-simulating, and sneezing-simulating are installed in the cinema. Specifically, 1 represents air compressor; 2 represents a set of odor tanks; 5 represents fresh air tank; 6 to 9 represent electromagnetic valve; 10 to 11 represent air pipes; 12 represents partition walls in the cinema; 13 to 21 represent multi-functional emission boxes; 22 to 30 represent pressure relief valve; 31 to 39 represent electromagnetic valves; 40 to 48 represent electromagnetic valves; and 49 to 51 represent water pipes.
Respectively, Diagrams 3 and 4 are the front view and vertical view of the multi-functional emission boxes represented by Diagram 13. The multi-functional emission box is an integral release and simulation device that incorporates odor-emitting, wind-blowing simulation, raining simulation, and sneezing simulation. Generally, each seat in a cinema has one multi-functional emission box installed. In Example 2 the multi-functional emission box is installed on the back of each seat with audiences sitting behind as the target of emission. Diagrams 3 and 4 show that the multi-functional emission box is a flat-shaped box with an odor exit (61) on the top-left side and a sprinkler head (59) and a fog-spraying head (60) on the top-right side. The sprinkler head (59) is used for the simulation of raining, and the fog-spraying head for the simulation of sneezing. On the bottom-left sides are the pressure relief valve (22) and an air pipe (11). Two electromagnetic valves (31 and 40) and one water pipe are located on the bottom-right side.
Diagram 5 is the B-B sectional drawing of Diagram 4 and represents the internal structure of the multi-functional emission box (13). Diagram 5 shows that buffer chamber (62) connects the odor exit (61) and the air pipe (11) on each side, with the sidewall of its chamber decorated with deadening felt (78) and its inside filled with sound-absorbing materials (70). Thanks to the deadening measures taken, the noise coming from the odor tank will be reduced to its minimal level.
In this example, each multi-functional emission box can contain as many as 24 or 36 or even more odor tanks, as is shown in Diagram 2, in which only odor tanks (2-5) are marked. Each odor tank contains different odors, and one of the odor tanks (5) in the diagram contains fresh air.
During film projection, the multi-channel device in the digital film projector detects the olfactory signals and sends them to the control device, which in turn transmits the signals to trigger one of the electromagnetic valves (6-9). After the air compressor forces the odor coming from the corresponding odor tank out into the air pipes (10 and 11), the odor will travel into the multi-functional emission boxes (13-21) by way of pressure relief valves (22-30). Audiences will smell odors in synch with the development of film plots as soon as they are discharged into the air through the buffer chamber (62) and odor exit (61). Those odors may include flower fragrance, perfume scent, coffee smell, cooking odor, fruit smell, smell of sourness, spiciness, funkiness, the smell of raw meat or fish, smoking smell, and the smell of gun powder, Odor tanks can be identified by labeling them so that different odor tanks are arranged in the order of their labels. For example, odor tank 1 is labeled Type A perfume, odor tank 2 Type B perfume, odor tank 3 jasmine fragrance, odor tank 4 coffee smell, and so on.
Electromagnetic valves 31 to 39 function differently from electromagnetic valves 40 to 48 because they are used for different sprinkler heads. Specifically, electromagnetic valves 31 to 39 control the sprinkler heads that simulate raining (e.g. Sprinkler head 59) while electromagnetic valves 40 to 48 control fog-spraying heads that simulate sneezing (e.g. fog-spraying head 60). Details of simulating raining and sneezing are as follows:
During film projection, tactual signals are detected by the multi-channel device in the digital film projector and are released to the control device, which in turn transmits raining-simulating signals or sneezing-simulating signals to trigger one set of electromagnetic valves (31-39) or one set of electromagnetic valves (40-48).
Then water will pass through the corresponding electromagnetic valves into the corresponding sprinkler heads or fog-spraying heads, producing the effects of raining or sneezing in accordance with the film plots.
The effect of raining is generated by spraying water upon above the audience and letting the water free fall. The effect of sneezing is realized by spraying fog directly and briefly onto the faces of the audiences. Sprinkler heads or fog-spraying heads differ from each other in terms of the diameters of the water holes or in terms of the ways water is sprayed in order to adapt to different plots of the film. The sprinkler heads or the fog-spraying heads are all replaceable.
During the process of simulating the effects of odor releasing, raining, and sneezing, the strengths of odor and water-spraying can be regulated by controlling the size of the apertures of the pressure relief valves (22-30), the electromagnetic valves (31-39), and the electromagnetic valves (40-48),
The process of simulating wind-blowing is described as follows: The multi-channel device in the digital film projector detects the tactual signal that simulates the effect of wind-blowing in synch with the plot development of the film and releases the signal to the control device, which then processes and releases the wind-blowing simulation signal. Specifically, in one case, the wind-blowing simulation signal coming from the control device will actuate the fan, which blows wind onto the audiences. In the second case, the wind-blowing simulation signal will trigger the control system components (such as the electromagnetic valve) in the wind exit while the air compressor or fan will also be actuated simultaneously. In the third case, the wind-blowing simulation signal will simultaneously actuate the air compressor, the odor tank that contains fresh air, and the control system components (such as the electromagnetic valve) in the odor exit, producing a simulation of natural wind.
Diagram 6 is the layout schematic drawing of this invention and illustrates the simulation of the effects of shaking and bumping. Diagrams 79-87 indicate audience seats in the cinema; Diagrams 88-96 are servo vibrators; and Diagram 97 specifies the signals that simulate shaking and bumping. The device that simulates shaking and bumping consists of the servo vibrator and the control system components. Being either the servo electromagnetic vibrator or the servo hydraulic vibrator, the servo vibrator is installed on the underside of audience seats and produces the effects of shaking and bumping by moving the seats back and forth, and up and down.
After the multi-channel device in the digital film projector detects the tactual signal and sends the signal to the control device, the control device will release the signal to the control system components (such as switches or relay devices) which activate the servo electromagnetic vibrator or the servo hydraulic vibrator. Then the audience seats are moved back and forth, and up and down. The shaking and bumping effects can be used to simulate the vibration of cars and ships, the zero gravity of airplanes or spaceships, free fall of humans from high cliffs, the effect of earthquakes, and other vibrating activities.
The following examples are used to demonstrate how olfactory signals and tactual signals are generated:
Suppose that the on-off program of the air compressor is set by Group A digits, the types of odor in olfactory signals by Group B digits, the strength of odor by Group C digits, and tactual signals by Group D digits. These programs are set as follows:
The settings of on-off program for the air compressor
B. The settings of the on-off program for the electromagnetic valve of the odor tank
The settings of program for the electromagnetic valve controlling the strength of odor
The settings of on-off program for the tactual signals controlling the electromagnetic valve for water-spraying
For example, 20 minutes after a digital film begins, the screen displays Jasmine flowers for three minutes. In this case, the digital film projector should release olfactory signal on the 20th minute to activate the electromagnetic valve in odor tank 3, which emits jasmine fragrance for three minutes.
30 minutes after the digital film begins, there appears a scene in which people are drinking coffee for 5 minutes. In this case, the digital film projector should release the olfactory signal on the 30th minute to activate the electromagnetic valve in odor tank 4, which emits coffee smell for five minutes. The coffee smell coming from the odor tank will be sent by the air compressor to the pressure relief valve before it travels into the multi-functional emission boxes, where it is emitted into the air in the cinema.
Whenever the odor emission period is over, digital film will release olfactory signal to activate the electromagnetic valve of the fresh air tank 0 to refresh the air for one minute. The setting of the olfactory signal for activating the electromagnetic valve of the fresh air tank 0 is “strong.” The air return entrance in the cinema should be in working order all the time.
Suppose that 56 minutes after the digit film begins, a 0.1-minute sneezing appears in the screen. The whole program settings for producing the effects of the above jasmine fragrance, coffee smell, and sneezing are as follows:
If there is no need to program the olfactory signals as “week” or “strong,” common electromagnetic valves can be used in this invention. If the division of odors into “weak” or “strong” is necessary, special electromagnetic valves such as servo electromagnetic valve should be the choice.
Installed outside the cinema together with the air compressor and attached directly to the electromagnetic valves, odor tanks are connected to the odor exits installed inside the cinema by means of air pipes. In addition, odor tanks are connected to pressure relief valves and multi-functional emission boxes that are installed in different locations inside the cinema. The air inside the cinema can be refreshed by the central air conditioner system. Or new fresh air entrance and return system may be installed. Air compressor should be capable of producing air pressure strong enough to force odors out. Water used for spraying can come from tap water or from the water pump.
