Definitions

  • This invention relates in particular to interactive mechanisms employing audible sound effects, and more generally to a game, relaxation, therapeutic, educational, learning, demonstration, simulation or the like mechanism providing audible sound effects.
  • Video games for PCs and arcade machines are very popular and represent a big market for the software and hardware industry. Great effort and money is spent in developing new powerful chips in order to achieve high quality realistic 3-D graphics and animation. So far, only very powerful and expensive machines are able to achieve this, and they are usually very big and certainly not portable. Sound effects play an important role in these games, but only in enhancing the effectiveness of the graphics.
  • most CD- ROM games give video high priority over audio, such that the audio is often monophonic in order to occupy minimum storage capacity. Even on a very atmospheric game like Broderbund's "Myst", the sound is mono. However, stereo sound is becoming more and more widely used as people buy bigger speakers.
  • Sid Meyer's Civilization] 2 (Civ 2), which uses stereo enhancement to spread out the stereo, ambient sounds.
  • European Patent Application 0378386 is another example where a video-game is provided with an internal loudspeaker through which monaural sound is played.
  • headphones can be used, and in this case a pseudostereophonic sound is generated.
  • the sounds are used simply to enhance the visual image and the sounds are not created as three dimensional sounds.
  • US Patent 4,281,833 discloses a non-visual ball and paddle game which is played through the medium of sound. Ball location paddle position and playing field are defined by variations in volume, tone pitch frequency and stereo separation by means of stereo head phones worn by the listener. The game disclosed in this U S Patent exploits essentially a two dimensional sound field.
  • each player is provided with a full-height paddle which he can move only to the left or right along a base line. It is not possible to determine whether the trajectory of the ball is high or low and whether it is moving diagonally from say upper left to lower right.
  • the U S Patent does not disclose the concept of creating a virtual three dimensional space and creating an environment where the player experiences the sensation of being immersed interactively in the virtual three dimensional space.
  • the present invention is based on the recognition that our proprietary Sensaura (Registered Trade Mark) three-dimensional sound technology, for example as described in our copending patent applications WO95/15069 and WO94/22278, has the ability to localise sounds in three dimensions with a high degree of accuracy for a listener.
  • a sound source such as music or a recorded noise
  • such technology provides the basis for a system based solely or mainly on audible effects wherein the aim is to estimate the position and/or direction of a sound in three-dimensional space, and to position and/or direct an object (real or imaginary), which may be another audible sound, a visible icon, or an imaginary location of the user, in response to this estimate.
  • the aim is to estimate the position and/or direction of a sound in three-dimensional space, and to position and/or direct an object (real or imaginary), which may be another audible sound, a visible icon, or an imaginary location of the user, in response to this estimate.
  • a mechanism for relaxation, therapeutics, education, learning, demonstration, simulation, playing a game, or the like comprising operable to reproduce, in the absence of visual cues, audible sound effects, the or each of which, is perceived by the listener to be at a location having three orthogonal co-ordinates in a three dimensional space surrounding, the listener object generating means for generating on object located at a second location in said space having three orthogonal co-ordinates, and object-moving means operable in response to input from the listener derived solely from cues in said the, or each sound effect to move the object relative to the, or each, sound effect.
  • the object to be positioned by the user may comprise a further audible sound, which, depending upon the rules of the game or other procedure, the player attempts to locate in a predetermined manner with respect to the sound effect.
  • the object may comprise a visible icon or other visible token to be positioned in a three-dimensional display, the position of the icon bearing a predetermined relation to the estimated position of the sound effect.
  • the object may be an imaginary object, present only in the user's imagination, such as the position of the user in an environment created by the sound effects.
  • the user by means of the user operable object- moving means attempts to position himself in a predetermined relationship to that of the sound effect, which may in turn lead to a "scene-shifting" where the nature of the sound effects change, as if the user is walking along a path.
  • background music may be added to augment the aural impressions of the user's location.
  • the transducer means preferably comprises headphones or earphones for reproducing sounds from the audio signals; alternatively, loudspeakers may be employed, in which case it is necessary to employ cross-talk cancellation to ensure the full binaural effect.
  • Binaural technology is based on recordings made using a so-called "artificial head” microphone system, and the recordings are subsequently processed digitally.
  • the use of the artificial head ensures that the natural three-dimensional sound cues - which the brain uses to determine the position of sound sources in three-dimensional space - are incorporated into the stereo recording.
  • Subsequent signal processing of the binaural signals anticipates the transaural crosstalk which occurs when listening to the recordings via loudspeakers, and ensures that this transaural crosstalk is cancelled.
  • Crosstalk occurs when an audio signal intended for one ear of a listener is also received by the other ear, and its cancellation ensures that the three-dimensional cues are effective on playback of the material, such that the brain can interpret the cues correctly. Without such processing, the recordings do not reproduce their three-dimensional attributes through loudspeaker auditioning. Crosstalk cancellation is described more fully in our copending
  • the term "binaural signals" is intended to mean two-channel or stereophonic signals which include one or more components representing audio diffraction effects created by an artificial head means positioned between a pair of spaced apart microphones.
  • the artificial head means may be, as is common, a precise model of a human head and torso with microphones in the ear structures; alternatively it may be something far less precise, for example a block or sheet of wood positioned between a pair of spaced microphones, which nevertheless creates diffraction signals from the source of sound signals; it may also be, as described more fully below, an electrical synthesis circuit or system which creates from an existing mono or stereo signal, stereophonic signals which include such diffraction signal components.
  • the source of audible sound effects may comprise a CD ROM, floppy disc or other data storage media containing one or more files with a basic library of sounds for playing a desired game. These sounds may be in compressed or coded form.
  • a processor may access the file for selecting one or more sounds for playing, in which case the sound information may be sent to a binaural processor for producing stereophonic binaural audio signals for reproduction.
  • an audio synthesis and tone generator circuit may be provided, so that a basic code for the sound may be issued from the processor, which causes the synthesiser to produce the desired frequencies and harmonics, which are then subject to binaural processing.

  • the invention is embodied as a game
  • the interaction between these sounds which according to the theme of a game could be following, chasing, hitting, matching, identifying, triggering, avoiding, or just listening, involves the user's input and skills and could dynamically change the course of the game.

  • a sound which represents an object or himself. Sp could either help the player to locate his orientation or can make player "visible” to the system which then acts against or for him.
  • the concept of a very simple game which falls into category 1. comprises a virtual flying insect like a bee, fly, or mosquito is flying around the head of the player who stays still.
  • the player can hear and locate the position of the insect by its sound and by means of a joystick, moves an object (a virtual catching device) which makes some kind of sound (e.g. Chinese chopsticks with a "click-click” sound).
  • a virtual catching device which makes some kind of sound (e.g. Chinese chopsticks with a "click-click” sound).
  • the system compares the x, y, z coordinates of the insect's sound with the coordinates of the catching device, takes into account the dimensions of the catching device and calculates whether the player "caught" the insect or not.
  • a scoring system according to the difficulty of the task can also be introduced. For example, catching the insect while moving will give you more points than catching it while it is steady. Another possibility would be for the user to choose the degree of skill required by selecting different insects and catching devices. For example, catching a big fly would be easier than catching a small mosquito, or using chopsticks would obviously be more difficult than performing the same task using a net or a spray can and so on.
  • monitor it is also possible to connect a monitor to the device that will allow the user visual feedback after trying to catch the flying insect.
  • the monitor can show how far or close the catching device was from the insect when the player hit the "catch" button.
  • the aim of the game could be that the player, following the "ghost", must find the right exit within a certain amount of time. If successful, the exit could lead to a "paradise” space.
  • Ambient sounds of waves, or waterfalls, the whisper of the forest and birds will reward the player who can then move to a more difficult stage of the game and so on. While the player moves in the darkness, he is likely to bump into objects and make other accidental noises. That makes him “visible” to "bad” creatures who then attack him or throw stones at him. The player hearing the sounds of oncoming dangerous objects must estimate where they come from and try to avoid them.
  • visual feedback can also be introduced by connecting a display.
  • the display would display graphics of the virtual environment.
  • Another concept which falls into the third category of scenarios, is a game similar to "blind man's bluff which could be played by two or more players. Each player wears headphones and has a joystick. One is playing the “blind man” so he hears all the sounds made by the other players and he tries to "catch” them. The others can hear only the sound coming from the "blind man” and try to avoid him. Each player makes a particular sound (selected by the player) which is randomly and automatically produced in order to provoke the "blind man”.
  • the system can also be used for the following applications:
  • the main advantage of this system is that the necessary power needed for animation and high quality realistic graphics is shifted from the machine to the human brain which is able to translate the audio environment into an imaginary visual one in a way which is unique for each individual.
  • Past experiences, emotions, personality and other subjective factors can influence the impact of the game opening up vast opportunities for a whole new gaming experience.
  • the system can be portable and that means that a new virtual reality environment can be experienced in places never before possible.
  • On the train, at the park, or at home lying on bed or even at work during a break people will be able to be immersed in a another ideal world where they can play a game or simply relax or even taste an exotic adventure. Future attachments to the system like voice recognition as an alternative or addition to the input device will create even more opportunities.
  • Video games and Virtual Reality are unknown things to blind people who now will be given the opportunity to enjoy and challenge themselves in a virtual world which is so close to theirs; a world of sounds.
