Description

Technical Field

[0001] The present invention generally relates to the technical field of sound diffusion for enhancing perception through tactile stimulation.

[0002] In particular, the present invention relates to a method and system for providing enhanced perception of music or speech or sound audio through tactile stimulation, and a method and system for providing tactile effects of music or speech or sound audio. Background Art

[0003] Many systems and methods are known for improving sound diffusion using enhanced perception.

[0004] However, the known solutions solve the technical problem of improving the perceived sound quality and ultimately always involve an improvement in the perception of auditory stimulation.

[0005] Some methods and systems are known that have also been expanded to include other sensory stimulation, such as in video game systems that enable the audio and visual perception of content (e.g., a video game) to be accompanied by tactile vibrations delivered to the user (e.g., via a glove). In this case, the tactile perception is added to the audio and visual perception, and does not enhance the audio perception as such, but simply adds a separate sensory channel.

[0006] However, considering sound diffusion in the proper sense, ie the diffusion and / or reproduction and / or listening of music, songs or speech audio, there is no known solution that would enrich this perception with tactile stimulation, and thus the need to provide such a solution has arisen.

[0019] The present invention takes into account the pressure waves and acoustic vibrations generated by any audio, which is largely musical, where the pressure waves and acoustic vibrations are completely synchronized with the original audio generated; the present invention transmits the pressure waves and acoustic vibrations to the human tactile system through mechanical or electronic devices so that they can be intercepted and perceived.

[0020] In other words, as will be described below, each sound event is considered to be a generator of the audible sound portion of vibrations and pressure variations.

[0021] refer to Figure 1-5 , a method for providing enhanced audio perception of music or speech or sound through tactile stimulation is described.

[0022] The method includes the following steps: receiving a signal representing the aforementioned music or voice or sound audio (represented as S or SE in the figure); at the same time, generating one or more tactile stimuli ST; and then modulating the one or more tactile stimuli ST based on the aforementioned received signal (S or SE) to generate one or more modulated tactile stimuli STM.

[0023] The method envisages then applying the aforementioned one or more modulated tactile stimuli STM together with the acoustic diffusion of the music or speech or sound audio to the listener so that the listener can enjoy the music or speech or sound audio both through auditory stimulation and through tactile stimulation.

[0024] The application of the modulated tactile stimulation STM occurs together with the sound diffusion of the musical audio in the sense that the application of the modulated tactile stimulation and the sound diffusion are simultaneous or substantially simultaneous (on a time scale comparable to the perception time of human senses). In this way, in fact, the auditory stimulation and the tactile stimulation cooperate in an overall perception that is enhanced and more satisfying to the user.

[0025] In the present solution, the correlation between auditory and tactile stimulation is ensured by the aforementioned simultaneity and the fact that the tactile stimulation is appropriately modulated in a manner that is closely related to the signal representing the auditory stimulation perceived by the user (as described above).

[0026] In all embodiments of the invention, the method of the invention can be applied where the audio is of any type, but in particular (in the preferred field of application) where the music or speech or sound audio provided for enhanced perception comprises human speech and / or sound and / or musical works and / or songs expressed in words or singing.

[0027] According to one embodiment of the method, the aforementioned tactile stimulation ST comprises a vibration perceptible by touch.

[0028] According to a choice of implementation, the aforementioned tactile stimulation comprises mechanical vibration; in this case, the step of generating one or more tactile stimulations comprises generating vibrations and / or mechanical waves by a vibration source and / or a mechanical wave source.

[0029] According to another embodiment, the aforementioned tactile stimulation includes pressure waves and / or acoustic vibrations; in this case, the step of generating one or more tactile stimulations includes generating pressure waves and / or acoustic vibrations by a pressure wave source and / or acoustic vibration source.

[0030] According to an embodiment of the method, the applying step comprises applying the generated vibrations to one or more parts of the listener's body after the generated vibrations have been modulated.

[0031] In this case, according to one option of embodiment, the modulating step includes modulating one or more tactile stimuli by a frequency suitable for a specific part of the listener's body, and the applying step includes applying the generated vibration to the specific part of the listener's body that is sensitive to the frequency after the generated vibration has been modulated.

[0032] According to one example of application of the method, the specific part of the listener's body to which the modulated vibration is applied includes a part of the tactile system and / or the skeletal system and / or the muscular system and / or the brain system.

[0033] In particular, according to a possible choice of embodiment, the specific part of the listener's body to which the modulated vibration is applied includes a part of the tactile system, which belongs to the group including: Ruffinicorpuscle, and / or Meissner corpuscle, and / or Pacinian corpuscle, and / or Merkel corpuscle, and / or free nerve fibers suitable for detecting tactile and / or pressure and / or stretch signals.

[0034] In this regard, the method provides wide flexibility in selecting the frequencies applied to preselected parts of the body based on the sensitivity of those parts of the body.

[0035] According to various options of implementation of the method, it is possible to remodulate the auditory frequencies to the optimal tactile frequencies.

[0036] For example, in the case of Pacinian corpuscles, tactile frequencies can range from 100 Hz to 500 Hz. In fact, Pacinian corpuscles are the most sensitive of the tactile receptors, capable of detecting pressure on the skin on the order of one micron; their sensitivity is greatest at 200 Hz, but they can also detect frequencies up to 500 Hz.

[0037] According to another example, in the case of Merkel's corpuscles, the tactile frequency can be from 5 Hz to 60 Hz. In fact, Merkel's corpuscles detect very low-frequency pressure stimuli.

[0038] According to one embodiment of the method, multiple tactile stimuli (modulated to respective optimal frequencies) may be applied simultaneously to different parts of the body.

[0039] According to one embodiment, the method may be applied in an environment where sound signals are diffused through electronic devices.

[0040] In this case, the aforementioned received signal is an electrical or electronic signal SE from a receiving instrument A, which is suitable for receiving music or voice audio transmitted in electronic form and converting it into electrical or electronic form, thereby transforming it into the "received electrical or electronic signal" (SE) defined above.

[0041] Furthermore, in this embodiment, the method comprises the further step of generating and diffusing an acoustic (i.e. sound) signal SA corresponding to the aforementioned music or speech audio, so that the acoustic (sound) signal SA is perceived by the listener while applying the aforementioned one or more modulated tactile stimuli STM.

[0042] According to a possible choice of implementation, the aforementioned receiving device A includes a radio or TV or telephone or computer or iPod or a receiving device associated with a speaker or an audio playback device associated with the projection of a video game or a movie.

[0043] According to another embodiment, the method can also be applied in the context of a sound signal SS coming from an audio or acoustic source and which is perceived directly by the listener without the mediation of an electronic device.

[0044] In this case, the receiving step comprises detecting the sound signal SS and generating a corresponding electric or electronic signal SE representing the detected sound signal SS.

[0045] In all the previously mentioned cases, in the method the individual reaches a point where there is an electrical or electronic signal SE representing a sound signal diffused and perceived by the user.

[0046] According to one embodiment option, the method comprises, before the modulation step, an additional step of processing said electric or electronic signal SE to obtain a drive signal SP. In this case, the modulation step comprises modulating said one or more tactile stimuli ST by means of the drive signal SP.

[0047] It can be easily understood that the fact of using an electric or electronic signal SE as the basis for generating the drive signal SP for the modulated tactile stimulation ST provides a wide range of possibilities for processing said signal, which are known per se, in order to optimize the timing of the tactile stimulation with advantageous flexibility and thus maximize its effect.

[0048] According to several possible variant embodiments, the aforementioned step of processing the electric or electronic signal SE comprises, by operating in the frequency domain and / or the time domain: frequency filtering the electric or electronic signal, and / or shifting the spectrum of the electric or electronic signal around a desired center frequency, and / or changing or distorting the spectrum according to predefined criteria.

[0049] It should be observed that in various options of implementation of the method, the tactile stimulation is modulated in a manner that is somewhat dependent on or coordinated with the sound, but in many respects it can be independent of the sound itself (e.g., with respect to intensity, amplification, or other aspects).

[0050] A corresponding method included in the present invention for providing haptic effects for music or speech or sound audio while listening to said music or speech or sound audio will now be described.

[0051] The method includes the following steps: receiving a signal (S or SE) representing the aforementioned music or speech or sound audio; then acoustically diffusing the music or speech or sound audio; simultaneously generating one or more tactile stimuli ST, and modulating the one or more tactile stimuli ST based on the aforementioned received signal to generate one or more modulated tactile stimuli STM.

[0052] Finally, the method envisages applying said one or more modulated tactile stimuli STM to the listener simultaneously with the acoustically diffuse step, so as to allow a tactile effect of the music or speech or sound audio associated with the received signal.
