TECHNICAL FIELD

[0001] The present disclosed subject matter relates to manipulating sound waves. More particularly, the present disclosure relates to systems and methods for translating sound waves into analogous tactile stimulation.

BACKGROUND

[0002] Millions of people worldwide suffer from hearing loss. The hearing loss may be mild, moderate, severe or profound. It can affect one ear or both ears, and leads to difficulty in hearing conversational speech or loud sounds. Hearing loss may result from genetic causes, complications at birth, certain infectious diseases, chronic ear infections, use of particular drugs, exposure to excessive noise, and also due to ageing. Disabling hearing loss refers to hearing loss greater than 40 decibels (dB) in the better hearing ear in adults, and a hearing loss greater than 30 dB in the better hearing ear in children.

[0003] People suffering from hearing loss, often use sign language as means of communication but they live in a silent world. Various technical solutions have been used to help deaf and hearing impaired people to experience the "sound" world. For example, there are dedicated dance stages in clubs of the "Association of the Deaf, whereby these stages are modified with large speakers that transfer the sound-waves to the floor so as to be sensed by the deaf dancers in the club.

[0004] Additionally, some deaf people hold household balloons (filled with air), that are affected by the sound waves in the air and therefore help experiencing some sounds, for instance gunshots or drums in a movie. However, when a pen moves on the table, a door squeak or talking occurs, deaf people cannot feel any change and the sound experience is therefore not complete.

[0005] Some commercially available solutions have tactile abilities whereby a sound triggers a vibration. Other commercially available solutions have wearable devices that translate a sound to a vibration. Thus, a user can recognize that there is music playing but cannot understand what kind of sound it is. [0006] However, none of the solutions provide a system that can discriminate sound waves (and particularly frequencies and harmonics) such that the individual components of any sound wave are translated differently into vibrations. It is therefore an object of the present disclosed subject matter to provide systems and methods of modifying sound waves with corresponding tactile feedback, such that each sound component is analyzed individually. Further objects and advantages of this subject matter will be disclosed in the detailed description.

In addition, the I/O module may also shape the gain and filter out noises from the core sound signal.

[0049] In some exemplary embodiments, an internet connection (not shown) may be used to connect STTS 100, the Internet connection may facilitate processes of communicating to a cloud base data repository that may comprise information associated with sound patterns representing, for example, musical instruments, animal sounds, male voice, female voice, children voice, vehicle noise, a combination thereof, or the like.

The memory module may also be used to retain sound patterns representation, look-up-tables mapping sound bands to zones (further described hereinafter), or the like.

[0051] In some exemplary embodiments, Sound Converter 110 may comprise a Sound Analyzer 112. Sound Analyzer 112 may be based on Digital Signal Processor (DSP) programmed for implementing sound analyzing and sound converting functionalities. In some exemplary embodiments, the sound analyzer may receive core sound signals from I/O module 114, which were originally received by a microphone, a Bluetooth signal, an ear jack, Wi-Fi signal, optical cord, or the like. By continuously analyzing the amplitude and frequencies of the core sound signal, the sound analyzer may determine properties of sound bands that make up the core sound signal. In some exemplary embodiments, the sound bands properties may be characterized by a single frequency, harmonic series, amplitude thresholds, band of adjacent frequencies, a combination thereof, or the like. Each sound band of a plurality of sound bands that make up the core sound signal may reflect a different acoustic effect, such as sound of: drums, voice, baby cry, motorcycle, singing, humming bird dog barking, a combination thereof, or the like. Additionally or alternatively, the sound analyzer may be configured to convert the plurality of sound bands into a plurality of electrical signals, each having specific electrical characteristics. It should be noted that the specific electrical characteristics of each electrical signal indicates a corresponding sound band. In some exemplary embodiments, converting a sound band into electrical signals may be done by modulating the amplitude and frequency of the electrical signal to match acoustic effects defined in a look-up-table. The look-up-table, stored in a data repository, may comprise information associated with sound patterns representing, for example, musical instruments, animal sounds, male voice, female voice, children voice, vehicle noise, a combination thereof, or the like.

[0052] In some exemplary embodiments, Sound Converter 110 may comprise Assembler 113. Assembler 113 may be an electronic circuit designed to aggregate the electrical signal into at least one primary signal and transmit the at least one primary signal to Device 120 (described later). The aggregation of the electrical signals produced by the sound analyzer may be done by a multiplexer, a mixer, sum amplifier, a combination thereof, or the like. In some exemplary embodiments, Assembler 113 may amplify the at least one primary signal and utilize I/O module 114 for transmitting the at least one primary signal to a device by either wires or wireless technologies, such as Bluetooth, Wi-Fi, a combination thereof, or the like.

[0053] In some exemplary embodiments, a hardware computing devices such as, for example, a smartphone, a notebook and a tablet may be utilized as a hardware platform for processing applications configured for implementing the sound converter functionalities.

[0054] In some exemplary embodiments, STTS 100 may comprise a device, such as Device 120. Device 120 may be adapted to touch a particular surface of a human skin, such as for example Conch 220 illustrated in Fig. 2B and Glove 400 illustrated in Fig. 4. The device 120 may comprise a plurality of actuators, such as Actuator 121, each of which may be dedicated to a predetermine zone of the particular surface that the device touches the skin. As an example, Glove 400 illustrated in Fig. 4 may be touching a backside surface of a hand with 16 actuators, where each actuator is allocated to a predetermine zone of the hand, as depicted in Fig. 4.

[0055] In some exemplary embodiments, each actuator, such as Actuator 121, may be driven by a dedicated electrical signal that is controlled by a driver. The actuator may be an electrical component configured to transform energy emitted by the electrical signal to mechanical vibration as a function of the amplitude and the frequency of the electrical signal. That is to say that the mechanical vibration stroke is related to the amplitude of the electrical signal and that the mechanical vibration frequency is related to the frequency electrical signal. In some exemplary embodiments, an actuator, such as Actuator 121, Actuator 310 shown in Fig. 3A and Actuator 410 shown in Fig. 4 may be a piezoelectric actuator, a linear resonant actuator, a nonlinear resonant actuator, or the like.

[0056] In some exemplary embodiments, the device may comprise a driver, such as Driver & Splitter (D&S) 126. D&S 126 may be an electronic circuit designed to receive from the sound converter signals based on communication technologies, such as for example Bluetooth, Wi-Fi, or the like. In some exemplary embodiments D&S 126 may be configured extract the primary signal (i.e. represents the aggregated electrical signal) from the received signal. In some exemplary embodiments, D&S 126 may comprise a de-multiplexer, a decoder, a multi-pole filter, or the like for splitting the at least one primary signal to its components, that is, the electrical signals comprising the aggregated electrical signal. Additionally or alternatively D&S 126 may amplify the electrical signals and route each electrical signal to its associated actuator. In some exemplary embodiments, a driver, such as D&S 126, may be assembled on Printed Circuit Board (PCB), FPGA, ASIC, PLA and physically integrated within a device, such as Driver 340 shown in Fig 3A. In some embodiments, a driver, such as Driver 440 shown in Fig. 4, may be separated from the device, such as Glove 400 shown in Fig. 4.

[0057] In some exemplary embodiments of the disclosed subject matter, Sound Converter 110 and Device 120 may be incorporated into one physical device. In such embodiments Assembler 113, a portion of I/O module 114, and a portion of D&S 126 may become redundant since the electrical signals may be wired directly to D&S 126 for amplifying and routing only.

[0058] Referring now to Figs. 2A-2B, these figures show a Sound to Tactile Translating System (STTS) 200. Fig. 2A illustrates the STTS 200 in an on-hook state, and Fig. 2B illustrates the STTS 200 in an off -hook state. The STTS 200 comprises a Docking Base 210 and at least one detachable Conch 220. The Docking Base 210 may be powered by AC or alternatively via internal batteries. Conch 220 may be attached to and/or detached from a matching Docking Area 211 of the Docking Base 210. Preferably, the coupling between the detachable Conch 220 and the Docking Base 210 may be magnetic with corresponding magnetic elements, so as to allow easy attachment and detachment of Conch 220 from the Docking Base 210. In some embodiments, Conch 220 may comprise Battery 222 that may wirelessly receive electrical power (e.g. charged) from the Docking Base 210 using a compatible circuit for wireless power transmission.

[0059] The STTS 200 may process sounds and translate sound waves into frequency- adjusted tactile vibrations, by which hearing impaired people may "feel" the sounds by physically experiencing a tactile feedback. With such feedback, after calibration and some practice, the user may interpret the tactile vibrations into individual sound patterns (e.g. musical instruments) and thus understand not just that there is for example general music playing, but also what kind of sound it is. In this way, a new "language" may be provided for the hearing impaired community, similarly to the Braille language for the blind. With this new language for the hearing impaired, an opportunity occurs for connection to the world of music, enjoyment of a deeper experience while watching films, and also being involved in multi-participants discussions, without feeling cut off as the user may differentiate between different people talking.

[0060] In some exemplary embodiments, the functionalities of the sound converter, typically housed in Docking Base 210, may be carried out at an external computerized device, such as a smartphone, a notebook, a tablet, or the like. Thus, the external computerized device may be adapted to process applications configured for sensing, analyzing, and processing functionalities of the sound converter. In such embodiments, where an external computerized device replaces the sound converter, Docking Base 210 may be utilized as docking base as well as for housing a power supply for charging at least one Conch 220.

[0061] Referring now to Fig. 3 A illustrates a cross-sectional view of a Conch 300. Conch 300 is ergonomically designed for a human hand and is covered by Layer 320 that corresponds to zones of the human hand. In some exemplary embodiments, vibrations generated by actuators such as Actuator 310, may traverse Layer 320 to corresponding zones of the human hand. In some exemplary embodiments, Conch 300 may comprise Driver 340. Driver 340 performs operations identical to the operations described for D&S 126, as shown in Fig. 1 and described hereinabove. The electrical signal output of Driver 340 may be wired directly to actuators such as Actuator 310. Thus, sound waves analyzed and processed by Sound Converter 100 shown in Fig. 1 may be transformed by Driver 340 to a mechanical vibration energy that stimulates corresponding zones on the human hand. Additionally or alternatively, Conch 300 may draw its energy from an external power supply (not shown), a Battery 330, a combination thereof, or the like. In some exemplary embodiments, a battery, such as Battery 330, of a device, such as Conch 300, may be wirelessly charged by the docking base while in on-hook state, as illustrated in Fig. 2B

[0062] In some exemplary embodiments of the disclosed subject matter, Conch 300 may comprise an enhanced version of Driver 340, which in an addition to its previously described operations, and may be configured to perform duties associated with Sound Converter 100 shown in Fig. 1. In such embodiments, Assembler 113, a portion of I/O module 114 as shown in Fig. 1, as well as a portion of D&S 330 may become redundant. [0063] Referring now to Fig. 3B showing several configurations of holding a device, such as Conch 333, in accordance with some exemplary embodiments of the disclosed subject matter. It should be noted that the topology of the actuators of the device may be designed to create vibrations coordinated with high, low, and intermediate audio frequencies, and to simulate the audio sense of music by means of vibrations coordinated with the tone scale from bass to soprano. The topology and the distribution of the actuators is a result of studying the hands touch sense mapping on hearing impaired participants. Test results also shows that a user (hearing impaired or not) can tactilely feel the vibrations in distributed zones according to the audio signals. After some practice, one can interpret the pattern of vibrations and distinguish if that is a guitar or piano for example.

[0064] Referring now to Fig. 4 showing an illustration of a Glove 400 comprising a plurality of Actuators 410 and a Driver 440, in accordance with some exemplary embodiments of the disclosed subject matter. It is appreciated that the human hand differs in sensitivity from other parts of the body, wherein a plurality of sensitivity zones (or pressure points) may sense delicate touch from multiple areas. For example, the hand may detect that two objects are touching the skin of the hand simultaneously in substantially close proximity zones, while other areas of the human skin have lower sensitivity. Thus, a human hand covered by Glove 400 that comprises actuators such as Actuators 410 that correspond to these zones, may provide means for differentiating between sound signals, for instance, separate musical instruments may be individually identified and then trigger the corresponding actuators. It should be noted that in some exemplary embodiments, actuators such as Actuator 410 may be connected to Driver 440 by a cable conducting the electrical signals.

[0065] Referring now to Fig. 5, showing a flowchart diagram of a method for translating sound to tactile in accordance with some exemplary embodiments of the disclosed subject matter.

[0066] In Step 510, sound signals intended for translation to tactile may be received. In some exemplary embodiments, I/O Module 114 capabilities (described above) may be utilized for obtaining sound signals from a verity of sources. Additionally, the I/O Module 114 may extract the core sound signals that represent relevant sound waves required for the translation process, from the sound signals.

[0067] In Step 520, the core sound signals may be analyzed by utilizing a processing algorithm configured to continuously determining the amplitude of each relevant frequency that comprises the core sound signal. The properties of the relevant frequencies may be predetermined and may be obtained from the memory.

[0068] In Step 530, a plurality of sound bands reflecting the sound signal content may be determined. In some exemplary embodiments, the sound bands may represent the most significant components comprising the core sound. That is to say that each sound band may reflect a different acoustic effect, such as voice, music, background noise, motorcycle, singing, humming bird dog barking, a combination thereof, or the like. In some exemplary embodiments, determining the plurality of sound bands that make up the core signal may be performed by characterizing the core signal main frequencies, harmonic series, amplitude thresholds, band of adjacent frequencies, a combination thereof, or the like.

[0069] In Step 540 the plurality of sound bands may be converted to plurality electrical signals. In some exemplary embodiments, each sound band is converted to a corresponding electrical signal characterized by specific properties. The conversion may be done by employing amplitude and frequency modulation scheme adapted to represent acoustic effects (i.e. sound band) with electrical signals. Following the modulation scheme the electrical signals may be shaped for controlling actuators, in accordance to a map (e.g. look-up-table stored on the data repository) used for allocating sound bands to zones on the human skin.

[0070] In Step 550, the electrical signals may be transmitted for energizing the actuators. In some exemplary embodiments, Assembler 113 may be used to aggregate the electrical signals into at least one primary signal. Additionally or alternatively, Assembler 113 may amplifies the at least one primary signal and utilize the I/O module 114 for transmitting the at least one primary signal to the actuators by either wires or wireless communication.

[0071] In Step 560, the mechanical vibration of the actuators may be activated by matching electrical signals. In some exemplary embodiments, a driver such as D&S 126 of a device, such as Device 120, may split the at least one primary signal to its components, (i.e. the electrical signals comprising the aggregated electrical signal). In addition, the D&S 126 may amplify the electrical signals and route each one of the electrical signal to its associated actuator in order to generate applicable mechanical vibration.

[0072] In Step 570, zones on the skin that are dictated by the device may tactilely stimulate. In some exemplary embodiments, a user (hearing impaired or not) may tactilely feel the vibrations in distributed zones according to the sound bands and the amount of the actuators comprised in the device. Since a correlation between sound bands and actuators is predetermined, then correlation with skin zones may be maintained as well. Thus, the different zones may provide means for differentiating between the sounds bands, for instance, separating between musical instruments. After some practice, the user may interpret the pattern of vibrations and distinguish if that is a guitar or piano, for example.

[0073] The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present disclosed subject matter. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of program code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures.
