The following specification particularly describes the invention and the manner in which it is to be performed.

TECHNICAL FIELD
The present invention relates to a navigation system, and more particularly, to a system and method for providing navigation in a premise.
BACKGROUND
In large corporate campuses/universities, when a guest arrives to meet with a desired host, it becomes difficult for the guest to know the exact location of the host. This situation is mainly observed when a meeting spot has not been finalized prior to the arrival of the guest or when the guest does not have any personal information about the host, say for example his/her phone number that may help the guest in establishing a contact with the host to know about his/her exact location.
Also, it may so happen that even though the meeting location is finalized beforehand, the host may not be available on that location but be moving within the premises. This situation will again put the guest in great difficulty. Thus, locating the host without having his/her personal or private information within the premise is a challenge. It, therefore, becomes important to devise a method and a system that enables the guest to navigate to the host without accessing any private information of the host and even when the host is non-stationary.
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.
SUMMARY
In one non-limiting embodiment of the present disclosure, a method for navigating a guest to a host in a premises are disclosed. The method comprises receiving a meeting request from a guest device to meet the host in the premises. The meeting request comprises guest-identity data and host-identity data. The method further comprises determining host noticeable parameters based on the host-identity data. The host noticeable parameters indicate publicly noticeable

characteristics of the host for whom the meeting request is received. Further, the method comprises enabling a set of tracking devices, from a plurality of tracking devices installed within the premises, to locate the host within the premises by detecting the host noticeable parameters. The set of tracking devices comprises two or more tracking devices coordinating with each other for tracking movement of the host within the premises after the host is located. The method further comprises determining latest location of the host based on the tracking of the movement of the host within the premises. Further, the method comprises enabling a navigation assistance entity to navigate the guest to the latest location of the host.
In another non-limiting embodiment of the present disclosure, a system for navigating a guest to a host in a premises are disclosed. The system comprises a receiving unit, determining unit, enabling unit, and navigating unit. The receiving unit receives a meeting request from a guest device to meet the host in the premises. The meeting request comprises guest-identity data and host-identity data. Further, the determining unit determines host noticeable parameters based on the host-identity data. The host noticeable parameters indicate publicly noticeable characteristics of the host for whom the meeting request is received. Further, the enabling unit enables a set of tracking devices, from a plurality of tracking devices installed within the premises, to locate the host within the premises by detecting the host noticeable parameters. Further, the set of tracking devices comprises two or more tracking devices coordinating with each other for tracking movement of the host within the premises after the host is located. Further, the determining unit determines the latest location of the host based on the tracking of the movement of the host within the premises. Once the host is located, the navigating unit enables a navigation assistance entity to navigate the guest to the latest location of the host.

DETAILED DESCRIPTION
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 particular forms disclosed, but on the contrary, the disclosure is to cover all modifications, equivalents, and alternative falling within the spirit and the scope of the disclosure.
The terms “comprises”, “comprising”, “includes”, 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.
Disclosed herein is a system and a method for navigating a guest to a host in a premises. When a meeting or appointment is fixed in a campus, one of the most hectic task is to locate the host or meeting venue within the premises. Specially, when the campus or premises are very large in area, it becomes a challenge for the guest to correctly locate the meeting venue or the host in the premises. This problem becomes more severe when the guest does not have contact details such as mobile number or email id of the host. Even, if the guest is able to locate the host, he/she wastes lot of time and effort in enquiring with the people or in guessing the correct path for reaching to the host.
The present disclosure overcome this issue by tracking the movement of the host without using any private information. Once the guest arrives at the premises, he/she may place a meeting request by using a guest device, which may be guest’s mobile phone or any kiosk or any other device provided in the premises. The guest may provide his/her name, mobile number, purpose of the meeting (i.e., guest-identity data) along with host name or host designation or department (i.e., host-identity data) which may help in identifying the host.
Upon receiving the meeting request along with the guest and host-identity data, the system determines host-noticeable parameters that may be prestored in a memory of the system. Since the system does not use any private/confidential information of the host, it relies only upon such host-

noticeable parameters such as host’s face, host’s posture and host’s voice or any other publicly noticeable characteristics which helps in detecting the presence of the host within the premises.
However, for identifying and tracking the host, the system may trigger or may take help from plurality of tracking devices installed within the premises. Such tracking devices may include for example CCTV cameras, voice recognizers, image/video analysis equipment and the like. It may be understood to the skilled person that these tracking devices may be stationary tracking devices or non-stationary tracking devices. For example, the tracking devices may be in a form of drones which may be capable of moving and tracking the host throughout the premises.
The tracking devices may also coordinate with each other to track the movement of host within the premises. Based on the tracking, the latest location of the host is determined and communicated to a navigation assistance entity. According to an embodiment of present disclosure, the navigation assistance entity may be a computing device or an autonomous vehicle. In case the navigation assistance entity is the computing device, a path is displayed and an audio-visual instructions may be provided to assist the guest to reach to the latest location of the host. However, when the navigation assistance entity is the autonomous vehicle, the guest may simply sit on the vehicle which may navigate the guest to the host location. The vehicle may have in-build map and capability to drive through the path and help the guest to reach to the host location. Thus, the present disclosure provides an easier and efficient technique for navigating the guest to the host without even accessing any private or confidential information of the host.
In the following detailed description of the embodiments of the disclosure, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the disclosure may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure. The following description is, therefore, not to be taken in a limiting sense.
Figure 1 shows an exemplary environment 100 for navigating a guest to a host in a premises in accordance with some embodiments of the present disclosure.

The premises may be a college campus or an IT park or a manufacturing plant having various buildings, departments, and people. Finding the exact building name or a host with whom a meeting/appointment is fixed is a tedious task for a person (guest) who may be new to that premises. Figure 1 shows the college campus as an example of the premises where the guest 101 wants to meet with the host 105. The college campus may have various buildings or places with their respective functionalities such as different engineering departments, Dean’s office, conference hall, library, cafeteria, auditorium, sports ground, administrative blocks and the like. However, it may be understood to a person skilled in art that the present invention may be implemented in various environments/premises, other than as shown in Figure 1.
The premises may be also equipped with various tracking devices 111, for example CCTV cameras, voice recognizers, image/video analysis equipment which may be connected with the system 102. According to other embodiments, the tracking devices 111 may be drones which are capable of moving and tracking the host within the premises. Apart from that, the premises may also have various navigation objects 109 such as a sign boards and a direction board for providing traveling guidance within the premise. The premises may also have navigation assistance entity 107 such as an autonomous vehicle as shown in figure 1. However, according to other embodiments of present disclosure, the navigation assistance entity 107 may also include a computing device like a tablet with an audio-visual assistance capability or even a robot which is capable of escorting the guest 101.
Now figure 1 is explained in conjunction with figure 2 which shows a block diagram 200 illustrating the system 102 for navigating the guest 101 to the host 105 in the premises in accordance with some embodiments of the present disclosure. The system 102 comprises a memory 210, a receiving unit 216, a determining unit 218, an enabling unit 220 and a navigating unit 222. According to an embodiment, the memory 210 may be communicatively coupled to the units 216-222 and may further comprise guest database 212 and host database 214. The guest database 212 may store guest related data, for example guest-identity data. Whereas, the host database 214 may store host related data, for example host-identity data or host noticeable parameters. In one embodiment, the guest and host related data may be stored within the memory

210 in the form of various data structures. Additionally, the aforementioned data can also be organized using data models, such as relational or hierarchical data models. Further, the units 216-222 may be dedicated hardware units capable of performing various operations of the system 102. However, according to other embodiments, the units 216-222 may a processor or an application-specific integrated circuit (ASIC) or any circuitry capable of executing instructions stored in the memory 210 of the system 102.
When the guest 101 arrives at the premises, he/she may place a meeting request by using a guest device 103. According to an embodiment, the guest device 103 may be a separate device like a kiosk or any handled device placed inside the premises. However, according to other embodiments, the guest device 103 may be guest’s mobile device. According to an embodiment, the receiving unit 216 may receive the meeting request from the guest device 103. While placing the meeting request, the guest 101 may provide some basic information about himself/herself and the host 105. For example, the guest 101 may provide his/her name or identity (i.e., guest-identity data) along with host’s name, a host-department, or a host-designation (i.e., host-identity data). The host-identity data helps the system 102 to identify the host 105 in the premise before starting the locating and tracking of the host 105.
Once the host 105 is identified, the determining unit 218 may determine host-noticeable parameters such as host’s face, host’s posture and host’s voice which may be stored in the host database 214. It may be understood that the host-noticeable parameters are publicly noticeable characteristics of the host 105, and therefore not a private or confidential information.
For example, the host 105 may be a head-of-department (HOD) of Computer Science Engineering (CSE) department. Now, when the system 102 understands that the host 105 is the HOD of CSE department, it may first check with the tracking device 111 placed location A. This is because, from the past learning experience, the system 102 may quickly decide which tracking device 111 to be checked first depending upon the identity of the host 105. For example, if the host identified to be the Dean of the college, then the system 102 may check with the tracking device 111 located nearby Dean’s office. However, in this example, since the host 105 is identified as the

HOD of CSE department, the first check point for the system 102 is the tracking device 111 which is located at HOD CSE cabin (location A).
However, it may happen that the host 105 may not be found at location A (for example host’s cabin where he/she supposed to be present) and have moved around the premises at various locations. As shown in figure 1, from the initial location A, the host 105 have moved to Dean’s office (i.e., location B) to library (i.e., location C) and to cafeteria (i.e., location D. Now, in this situation, the host noticeable parameters i.e., non-private information plays a role in locating and tracking the host 105 within the premises.
For this, the enabling unit 220 enables or triggers a set of tracking devices 111 amongst the plurality of tracking devices to locate the host 105. For example, as soon as the host 105 moves from his/her initial location A to location B, the tracking device 111 at location B may detect the presence of the host 105 by noticing host’s voice or host’s face or host’s walking style. The tracking device 111 at location B may also coordinate with the tracking device 111 of host’s previous location A to reaffirm the presence of the host at location B. Similarly, when the host 105 moves from the location B to the location C, the tracking device 111 at location C informs about the host location to tracking device 111 of location B which further passes this information to tracking device 111 of the initial location A.
Similarly, when the host 105 moves from location C to location D, the same level of coordination happens between the tracking devices of location C and D. By enabling such coordination between the tracking devices 111, the system 102, at any point of time, may quickly locate the host 105 within the premises. That is, instead of querying each tracking device 111 in the premises, the system 102 is able to query only few or a set of tracking devices 111 which are actually involved in tracking the host 105. This helps the system 102 to optimize its searching capability of the host 105 within the premises. Thus, the coordination of the tracking devices 111 not only locates the host 105 but also helps in tracking the movement of the host 105 within the premises from time to time.

Now, suppose the host 105 was at location D when he/she receives an alert about the guest’s 101 arrival in the premises. The host 105 then moves to the conference hall (i.e., location E). The tracking device 111 installed at location E would now detect the host’s 105 presence and send this information to tracking device 111 of location D. Thus, the latest location of host is determined as location E.
Post determining the latest location “location E” of the host 105, the next task is to navigate the guest 101 to the host 105. For this, the present disclosure discloses various alternatives for navigating the guest 101 to the host 105. For example, the navigating unit 222 of the system 102 may enable the navigation assistance entity 107 to navigate the guest 101 to the latest location of the host 105. The navigation assistance entity 107 as shown in figure 1, for example, is an autonomous vehicle. However, according to other embodiments of present disclosure, the navigation assistance entity 107 may be a computing device having audio-visual assistance capability or may be a robot for escorting the guest 101.
For providing navigation, the navigating unit 222 may first determine a path from the guest location to the latest location of the host 105 by using a map associated with the premises. The map may be premises map which may be stored in the memory 210 of the system 102. An example of the path is shown in figure 1 using multiple arrows. It can be observed that the arrows start from the “Administrative Block and Reception” (i.e., guest location) and moves towards the conference hall (location E) which is the latest location of the host 105.
In case the navigation assistance entity 107 is the computing device, the path determined may be displayed on it, and simultaneously, the audio-visual assistance is provided to the guest 101 until the guest 101 reaches to the latest location of the host 105. As the guest 101 approaches toward the latest location of the host 105, the path displayed is automatically adjusted on the computing device. For example, once the guest 101 reaches to the entrance of the conference hall (latest location of the host 105) and suppose the conference hall is at the third floor, the navigation assistance entity 107 may provide an option to the guest 101 of either choosing the staircase or elevator to reach to the third floor.

Now in case the navigation assistance entity 107 is an autonomous or any vehicle, the system 102 may determine one or more dropping locations in a predefined proximity of the latest location of the host 105. This is because, considering the latest location at the third floor, the vehicle may not be able to climb the stairs, and therefore, determines the dropping locations. According to an embodiment, the one or more dropping locations may be the nearest possible locations from the latest location of the host 105 to drop the guest 101. According to present example, the dropping location may be at the entrance of the conference hall (latest location of host 105). Hence, once the dropping location is determined, the system 102 enables the vehicle to drive to the dropping location based on the path. While driving, the vehicle may use a plurality of navigation objects 109 such as sign boards and direction boards on the path of the vehicle. This way, the system 102 provides an efficient technique for navigating the guest 101 to the host 105 in the premises.
Figure 3 depicts a flowchart illustrating a method for navigating a gust to a host in a premises in accordance with some embodiments of the present disclosure.
As illustrated in figure 3, the method 300 includes one or more blocks illustrating a method to navigate the guest to the host in the premises. The method 300 may be described in the general context of computer executable instructions. Generally, computer executable instructions can include routines, programs, objects, components, data structures, procedures, modules, and functions, which perform specific functions or implement specific abstract data types.
The order in which the method 300 is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Additionally, individual blocks may be deleted from the methods without departing from the spirit and scope of the subject matter described herein. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof.
At block 302, receiving unit 216 receives a meeting request from a guest device 103 by a guest 101 upon entering a premises. As discussed in the above paragraphs, the meeting request comprises host-identity data and guest-identity data. The host-identity data further comprises host

name, host department and host designation, whereas the guest-identity data comprises guest-name and guest-mobile number.
At block 304, the determining unit 218 may determine host noticeable parameters from a memory 212 of the system 102. The host noticeable parameters may be the non-private parameters such as host’s face, host’s posture and host’s voice that help in the identification of the host within the premises.
At block 306, the enabling unit 220 may enable a set of tracking devices, from a plurality of tracking devices 111, to locate the host 105 within the premises by detecting the host noticeable parameters. The set of tracking devices coordinates with each other for tracking movement of the host 105 within the premises after the host is located.
At block 308, the determining unit 218 may determine the latest location of the host 105 based on the tracking of the movement of the host 105 within the premises.
At block 310, the navigating unit 222 may enable the navigation assistance entity 107 to navigate the guest 101 to the latest location of the host 105.
