TECHNICAL FIELD
The present subject matter is related, in general to a communication system, and more particularly, but not exclusively, to a method and a system for establishing a bi-directional communication between users present inside and outside of a vehicle without lowering vehicle window glass.
BACKGROUND
Travel demand has been continuously increasing as a result of rapid population growth and economic development. The major risks involved during distant traveling are personal safety, adverse weather conditions, communication between the user present inside and outside of a vehicle. Also, it is necessary for distant traveling persons to keep themselves safe from transmission of pandemic diseases and avoiding from contacting with any infection during the journey. Further, it is inevitable in such long journey that user present inside the vehicle has to communicate with the other road users and users at fuel refilling stations for one or the other reasons which would result in lack of maintaining a social distance which might lead to untoward incidents. Further, adverse weather conditions related to reduced visibility act as a barrier for communication with the users outside the vehicle.
In addition, adverse weather conditions, such as heavy rain, extreme sun radiation, restricts users inside the vehicle from having a verbal communication with the users outside the vehicle. In addition to aforementioned challenges, users traveling between different regions like, different districts, states and countries encounter language barrier as users are not well versed with language spoken in the travelling region. Thus, it becomes a requirement for distant travelling persons to know the regional language to communicate with the local persons. However, in reality, it is difficult for people to learn and communicate in local language all the time. Thus, the verbal communication of the distant travelling persons inside the vehicle with the people on the road towards the opposite door-side of the vehicle can lead to inaccurate communication and cause inconvenience. In another example, having a conversation with unknow person on roadside may lead to untoward event like chain snatching, knife attacking, theft of valuable. Thus, to avoid such incidents, users inside the vehicle prefer to have conversion with persons on the roadside without lowering the vehicle window glass. However, such communication with persons on the roadside might lead to unclear. Therefore, users

travelling in the vehicle may not get the required assistance like navigation guidance from the persons on the roadside, which is essential during distant travelling.
The information disclosed in this background of the disclosure section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

In the present document, the word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any embodiment or implementation of the present subject matter described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
While the disclosure is susceptible to various modifications and alternative forms, specific embodiment thereof has been shown by way of example in the drawings and will be described in detail below. It should be understood, however that it is not intended to limit the disclosure

to the specific forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the scope of the disclosure.
The terms “comprises”, “comprising”, “includes”, “including” or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a setup, device, or method that comprises a list of components or steps does not include only those components or steps but may include other components or steps not expressly listed or inherent to such setup or device or method. In other words, one or more elements in a system or apparatus proceeded by “comprises… a” does not, without more constraints, preclude the existence of other elements or additional elements in the system or method.
The present disclosure relates to a method and a system for establishing a bi-directional communication between users present inside and outside of a vehicle without lowering vehicle window glass. In an embodiment, the system may be configured in the vehicle. Consider a scenario where a user is travelling in a vehicle from one place to another, the user may require communicating with the local users for one or more information. The one or information are the present location, nearby fuel refiling station, nearby refreshments, and so on. The control unit initiates the bi-directional communication between a first user [user 1] present inside the vehicle and a second user [user 2] outside the vehicle when the first user wishes to communicate with the second user. The bi-directional communication between the users is initiated when the vehicle engine is in ON state condition.
In an embodiment, the control unit determines the requirement of the bi-directional communication on one of Left Hand (LH) side or Right Hand (RH) side of the vehicle. After receiving activation of a bi-directional LH side or RH side input from the first user, bi-directional communication is established on one of the sides of the vehicle. The bi-directional communication is determined on the LH side when the first user wishes to communicate with the second user present on the LH side of the vehicle. Similarly, the bi-directional communication is determined on the RH side when the first user wishes to communicate with the second user present on the RH side of the vehicle.
Based on the languages of the first user and the second user, the control unit determines the requirement for a language translator for the bi-directional communication on one of the LH side or RH side of the vehicle. The requirement of the language translator is determined on the LH side of the vehicle upon receiving activation of a translator LH side input from the first

user. Similarly, the requirement of the language translator is determined on the RH side of the vehicle upon receiving activation of a translator RH side input from the first user. The translator LH side input and the translator RH side input are displayed on a display module, connected to the control unit, inside the vehicle. Further, the control unit establishes the bi-directional communication between the first user and the second user with the language translator on one of the LH side or RH side of the vehicle. The language translator is activated when the first user language is different from second user language. In another scenario, when languages of both the first user and second user are same, then the control unit establishes the bi-directional communication without the language translator on one of the LH side or RH side of the vehicle.
In this manner, the present disclosure discloses a method and system for establishing a bi-directional communication between users present inside and outside of a vehicle without lowering vehicle window glass.
Fig. 1a shows an exemplary environment for establishing a bi-directional communication between users present inside and outside of a vehicle without lowering vehicle window glass, in accordance with some embodiments of the present disclosure.
The environment 100 comprises a vehicle 101, a control unit 107 configured in the vehicle 101 for establishing a bi-directional communication 109 between a first user [user 1] 103 present inside the vehicle 101 and a second user [user 2] 105 present outside the vehicle 101. The control unit 107 comprises a processer 112 interfacing the memory 114 (shown in Fig. 1b). The control unit 107 may also include an Input/Output (I/O) interface 111 (shown in Fig. 1b).
As an example, when a user who is driving the vehicle 101 from one location to another location, may wish to communicate with nearby local users for collecting one or more information. For example, the one or more information may be about present location, nearby fuel refiling station, nearby refreshments, and the like. The control unit 107 initiates the bi-directional communication 109 between users present inside and outside of the vehicle 101, when the first user 103 (present inside the vehicle 101) wishes to communicate with the second user 105 (present outside the vehicle 101). The bi-directional communication 109 between the users is initiated when the vehicle 101 engine is in ON state.
In an embodiment, the control unit 107 determines the requirement of the bi-directional communication 109 on one of Left Hand (LH) side or Right Hand (RH) side of the vehicle 101.

The vehicle 101 comprises a display module 201 connected to the control unit 107. The display module 201 displays a LH side input and the RH side input as shown in Fig. 2b. Once the need for bi-directional communication 109 has been determined, the first user 103 activates the LH side input or RH side input of the vehicle 101. The bi-directional communication 109 is determined on the LH side when the first user 103 wishes to communicate with the second user 105 present on the LH side of the vehicle 101 and activates the LH side input. Similarly, the bi-directional communication 109 is determined on the RH side when the first user 103 wishes to communicate with the second user 105 present on the RH side of the vehicle 101 and activates the RH side input.
In an embodiment, the control unit 107 determines the requirement of a language translator for the bi-directional communication 109 on one of the LH side or RH side of a vehicle 101 based on the language of the first user 103 and the second user 105. For example, consider the situation when the first user 101 wishes to communicate with the second user 105, where the second user 105 is present on the left side of the vehicle 101. However, if the second user 105 native language is different from the native language of the first user 103, then the first user 103 will activate the language translator LH input displayed on the display module 201 as shown in Fig. 2b. The control unit 107 determines the requirement of the language translator on the LH side of the vehicle 101 upon receiving an activation of the translator LH side input from the first user 103.
Similarly, the control unit 107 determines the requirement of the language translator on the RH side of the vehicle 101 upon receiving an activation of the translator RH side input from the first user 103. For example, consider the situation when the first user 101 wishes to communicate with the second user 105, where the second user 105 is present on the right side of the vehicle 101. However, if the second user 105 native language is different from the native language of the first user 103, then the first user 103 will activate the language translator RH input as shown in Fig. 2b.
Fig. 1b shows a block diagram of a control unit for establishing a bi-directional communication between users present inside and outside of a vehicle without lowering vehicle window glass, in accordance with some embodiments of the present disclosure.
In one implementation, a control unit 107 receives data through I/O interface 111. As an example, the received data is stored within memory 114. In an embodiment, the data includes

an input data 116, an output data 117, and other data 118. In the illustrated Fig. 1b, one or more modules stored in memory 114 are described herein in detail.
In an embodiment, the data may be stored in memory 114 in the form of various data structures. Additionally, the aforementioned data can be organized using data models, such as relational or hierarchical data models. The other data 118 may store data, including temporary data and temporary files, generated by modules for performing the various functions of the control unit 107.
In an embodiment, the input data 116 is the data which is captured from the first user 103 and the second user 105. The output data 117 is the data which would be provided as an output to the first user 103 and the second user 105.
In an embodiment, the data stored in memory 114 are processed by the modules of control unit 107. The modules may be stored within the memory 114 as shown in Fig. 1b. As an example, the modules, communicatively coupled to the processor 112, may also be present outside the memory 114.
In one implementation, the modules may include, for example, an initiating module 120, a determining module 121, an establishing module 122, and other modules 123. The other modules 123 may be used to perform various miscellaneous functionalities of the control unit 107. It will be appreciated that such aforementioned modules may be represented as a single module or a combination of different modules.
In an embodiment, the initiating module 120 may be configured to initiate a bi-directional communication 109 between a first user 103 inside the vehicle 101 and a second user 105 outside the vehicle 101. The bi-directional communication 109 between users present inside and outside of the vehicle 101 is established when the first user 103 (present inside the vehicle 101) wishes to communicate with the second user 105 (present outside the vehicle 101). Thereafter, the first user 103 activates the bi-directional LH side input or RH side input once the requirement for bi-directional communication 109 has been identified.
In an embodiment, the determining module 121 may be configured to determine the requirement of the bi-directional communication 109 on one of LH side or RH side of the vehicle 101. The bi-directional communication 109 is determined on the LH or RH side of the vehicle 101 upon receiving activation of a bi-directional LH or RH side input from the first

user 103. When the first user 103 desires to communicate with the second user 105 present on the LH side of the vehicle 101, bi-directional communication 109 is established on the LH side. Similarly, when the first user 103 desires to communicate with the second user 105 present on the RH side of the vehicle 101, bi-directional communication 109 is established on the RH side.
In an embodiment, the determining module 121 is also configured to determine the requirement of a language translator for the bi-directional communication 109 on one of the LH side or RH side of the vehicle 101 based on the language of the first user 103 and the second user 105. The language translator is required only when the language of the second user 105 is different from the language of the first user 103. The requirement of the language translator is determined on the LH side of the vehicle 101 upon receiving activation of a translator LH side input from the first user 103. Similarly, the requirement of the language translator is determined on the RH side of the vehicle 101 upon receiving activation of a translator RH side input from the first user 103. After identifying the requirement for a language translator for bi-directional communication 109 on either the LH or RH side of the vehicle 101, the control unit 107 establishes the bi-directional communication 109.
In an embodiment, the establishing module 122 may be configured to establish the bi-directional communication 109 with one of the language translator on one of the LH side or RH side of the vehicle 101, when the first user 103 language is different from second user 105. The establishing module 122 is also configured to establish the bi-directional communication 109 without the language translator on one of the LH side or RH side of the vehicle 101, when both first user 103 and second user 105 languages are the same.
Exemplary Scenario:
As shown in Fig. 2a, the display module 201 displays the LH side input, RH side input, language translator LH and language translator RH. When the first user 103 (present inside the vehicle 101) wishes to communicate with the second user 105 (present outside the vehicle 101), the first user 103 activates the LH side input or RH side input. As an example, when the first user 103 wishes to interact with the second user 105 present on the LH side of the vehicle 101, the bi-directional LH side input is activated. Similarly, when the first user 103 wishes to interact with the second user 105 present on the RH side of the vehicle 101, the RH side input is activated.

After activating either a bi-directional LH side input or a bi-directional RH side input, the control unit 107 receives a first input captured from the first user 103 through an input device 2031 configured inside the vehicle 101 as shown in Fig.2b. The input device 2031 configured in the vehicle 101 may be located at a front compartment of the vehicle 101 proximal to the first user 103 as shown in Fig. 2b. For example, the first input was captured from the first user 103 through an input device 2031 (for example a microphone) located inside the vehicle 101 upon activating one of a LH side input or a RH side input. For example, the first input from the first user 103 may be “What is your name”. After receiving the first input, the control unit 107 may transmit the first input to either a RH ORVM 207 assembly or an LH ORVM 209 assembly as shown in Fig. 2b. The RH ORVM 207 assembly is configured on the RH side of vehicle 101 and LH ORVM 209 assembly is configured on the LH side of vehicle 101. The LH ORVM 209 and the RH ORVM 207 comprises input device 203 and the output device 205. The input device 2032 which is located in the RH ORVM 207 assembly, is configured to receive input from the second user 105. Similarly, the input device 2033 which is located in the LH ORVM 209 assembly, is configured to receive input from second user 105 as shown in Fig. 2c. As an example, the input device 203 may be a microphone.
The second user 105 on the left side of the vehicle 101 may hear the output through the output device 2053 configured in the LH ORVM 209 assembly as shown in Fig. 2c. Similarly, the second user 105 on the right side of the vehicle 101 may hear the output through the output device 2052 configured in the RH ORVM 207 assembly. As an example, the output device 205 may be a speaker. For example, the second user 105 hears the transmitted first input signal i.e., “What is your name?”. Upon the transmission of the first input, the control unit 107 may receive a second input captured from the second user 105 through the input device 203 located in RH ORVM 207 assembly or the LH ORVM 209 assembly. The second input signal is captured from the second user 105 in response to the transmitted first input, for example, “My name is John”. The received second input is heard by the first user 103 through the output device 2051 (for example, a speaker) inside the vehicle 101. For example, the first user 101 will hear the voice of the second user 105 through the speaker located inside the vehicle 101. The output device 2051 inside the vehicle 101 is located at a front compartment of the vehicle 101 proximal to the first user 103. In an embodiment, both LH ORVM 209 assembly and the RH ORVM 207 assembly comprises one or more visual indicators for indicating receipt of the first user 101 input. As an example, the one or more visual indicators are bi-directional LH or RH activation

indication, translator LH or RH activation indication, selected language indication and translated language.
As shown in Fig. 2a, the display module 201 displays the LH side input, RH side input, language translator LH and language translator RH. Based on the language of the first user 103 and the second user 105, the control unit 107 determines the need for a language translator for bi-directional communication 109 on one of the LH side or RH side of a vehicle 101. The control unit 107 initiates bi-directional communication 109 upon determining the requirement of the language translator for bi-directional communication 109 on either of LH side or RH side of the vehicle 101. Thereafter the control unit 107 receives activation of one of a translator LH side input or a translator RH side input through the display module 201. When one of the translator LH side or the translator RH side input is activated, then the control unit 107 converts the received first input to the language specified for the second user 105. For example, if the first user 103 selects English language for himself and also first user 103 selects Hindi language for the second user 105, then the English language will be translated into Hindi. After converting the received first input, the control unit 107 transmits the converted first input to the RH ORVM 207 assembly or an LH ORVM 209 assembly. The converted first input is heard by the second user 105 present on LH side or RH side of the vehicle 101 through the output device 205 (for example, a speaker). The second user 105, for example, will listen to the first user’s input in Hindi through the output device 205. For example, the second user 105 hears the transmitted first user 101 input in Hindi language “Tumhaara naam kya he”. The control unit 107 receives a second input captured from the second user 105 through an input device 2032 located in RH ORVM 207 assembly or an input device 2033 located in the LH ORVM 209 assembly after transmitting the converted first input. In response to the first input, the second user 105 captures the second input signal in Hindi. Upon receiving the second input, the control unit 107 converts the received second input from Hindi language to the English language. The converted second input is heard by the first user 103 through the output device 2051 inside the vehicle 101. The output device 2051 inside the vehicle 101 is located at a front compartment of the vehicle 101 proximal to the first user 103. "My name is John," for example, will be translated from Hindi into English, which is the first user’s 103 preferred language. The second user’s 105 voice will be heard as "Mera naam John hai" through the output device 2051 say speaker located at a front compartment of the vehicle 101.

Fig. 3 shows a flowchart illustrating a bi-directional communication with one of a language translator or without the language translator on one of Left Hand (LH) side or Right Hand (RH) of a vehicle, in accordance with some embodiments of the present disclosure.
At block 301, When the vehicle's engine is turned on, the method initiates a bi-directional communication 109 between users present inside the vehicle 101 and outside the vehicle 101. At block 303, the method determines the requirement of the bi-directional communication 109 between users present inside and outside the vehicle 101. If the requirement of having communication between the users is determined, then the method proceeds to block 307. If there is no requirement determined, then the method terminates at block 305. At block 307, the control unit 107 determines the requirement of the bi-directional communication 109 on one of the LH side or RH side of the vehicle 101. If the bi-directional communication 109 is determined on LH side of the vehicle 101, then the method proceeds to block 309. If the bi-directional communication 109 is determined on RH side of the vehicle 101, then the method proceeds to block 311.
At block 309, the control unit 107 determines the requirement for a language translator for the bi-directional communication 109 on LH side of the vehicle 101. If the language translation is required, the method proceeds to block 313. Else the method proceeds to block 315. At block 315, the bi-directional communication 109 is established without the language translator when language of both the first user 103 and second user 105 is same. At block 313, the language translator LH is activated upon detecting presence of the second user 105 on LH side of the vehicle 101.
