Definitions

  • the present invention relates to a multimedia system for the control and generation of music and two-and three-dimensional animation in real time, controlled by movement detectors.
  • the present invention is intended to permit direct interaction between the movement executed by a subject on a "stage" and a set of sound, light and animation effects obtainable in real time.
  • the subject of the present invention is therefore a multimedia system for the control and generation of music and two- and three-dimensional animation in real time, comprising: sensor means for movement detection; a unit for the acquisition and pre-processing of data detected by the said sensors; a unit for processing the acquired data, and one or more sound generation, and/or image generation and/or control, and/or light effects control units, controlled by the said data processing unit.
  • the sound generation unit and the systems for image generation and light effects may be controlled directly by the acquisition and pre-processing unit.
  • the said movement detection sensors may be thermal, electromagnetic, mechanical, infrared, ultrasonic or laser sensors, or an image acquisition system, singly or in combination with each other.
  • Figure 1 shows schematically the components used in one embodiment of the system of the invention.
  • the number 1 indicates the sensors, for example electromagnetic sensors for movement detection, forming part of a network of sensors disposed on the ceiling of a room whose floor is delimited by the platform 101.
  • the platform 101 and any lateral walls or supports may also be provided with sensors, for example mechanical sensors (not shown).
  • Further means for movement detection and image acquisition, in the form of one or more video cameras 201, may also be provided. All these movement detection means are connected to a unit 2 for acquisition and pre-processing of the detected data.
  • the unit 2 is connected to a processing unit 3, for example a computer having a suitable configuration, which in turn is connected to the peripherals 4 and 5, which are, respectively, the sound generation unit 4 and the image generation system 5 which projects the image producted by it on a screen 105.
  • the sound generation unit 4 is connected to a mixing and amplification panel 104 to which loudspeakers 204 are connected.
  • the operation of the system of Figure 1 is shown schematically in the block diagram of Fig. 2.
  • the movement detector means 1 mechanical sensors of the platform 101, electromagnetic sensors 1 and video cameras 201 detect the movement of a subject inside the space covered by them.
  • the said signals from the sensors 1, 101 and video cameras 201 are then acquired and pre-processed by the unit 2.
  • the level of pre-processing of this unit 2 depends essentially on its type of configuration.
  • the unit may consist of an I/O card, a so-called "custom" card designed ad hoc, or PLCs (programmable logic controllers). In the first case, its processing capacities will be relatively limited, while in the last case the unit 2 may also be capable of controlling the peripherals of the system when these have suitable characteristics.
  • the data acquired in the unit 2 are then transferred to the processing unit 3, which commonly consists of a computer with a suitable configuration, in which the said data are processed by suitable software.
  • the unit 3 is able to control the functions of the peripherals 4, 5 and 6 which are, respectively, the sound generation unit, the image generation and/or control system, and the light effects control system (not shown in Fig. 1).
  • the three units, which may operate in a way co-ordinated by the unit 3, are however completely independent of each other.
  • the sound generated by the sound generation unit 4, in the present case a synthesizer, is then mixed and amplified by the panel 104 and sent to the loudspeakers 204.
  • the images are similarly generated by the image generation or control system 5 and projected by it onto the screen 5.
  • the sensor 1 that seems to be most suitable for this simplified version of the device of the invention is a foot sensor in the form of a sort of carpet, or an active infra red sensor.
  • the sampling, processing and sound generation units 2, 2' and 4 are advantageously formed in an integrated single board ISB, as a "stand-alone” unit able to produce sound (sent to the home stereo system 204) and programmable by cartridges (not shown) like any other video game unit.
  • the said embodiment of the invention may be produced at a very low price, is easy to mount, easy to use and easy to "take away”: it is a game for children, a simple "sound cage” for teenager and an effective gymn-aid for the whole family.
  • FIG 4 a third embodiment of the invention is shown, which is also apt for "audiogames".
  • the device according to this embodiment is provided with a large number of sensors, like fine motion sensors 1', trajectories followers 1'' and sound/voice analysis 1'''. These sensors will integrate the sensor system 1 (active infrared and pressure). Also this system is provided with sampling, preprocessing, supervision and sound generation units 2, 2', 3 and 4 respectivelly.
