BACKGROUND OF THE INVENTION
Fishing industry plays a vital role in fulfilling food and non-food needs and promoting trade for most nations across the world. Along with agriculture, fishing plays a vital role

for the economic growth of a country. Like agriculture, fishing is a traditional occupation and mostly carried out by the population staying in the rural areas.
There has been a lot of research in the field of fishing to equip the fishermen with better
techniques to have better catches and increase their turnover. The research work however,
is restricted to the fishing equipment, the nets, navigation details providing devices,
construction of the fishing boats or ship or the like. Though these researches facilitate the
fishermen to gain access to latest equipment and techniques but other than these the I
fishermen deal with various problems in their day to day lives.
These challenges are related to where to do fishing, which fish to dry, which fish to sell, which fish can be exported and the like. The fishermen are dependent on other fishermen on all above mentioned problems. Also, the information on latest government reforms, new provisions, and information on potential fishing zones does not reach the fishermen in time. All these information is present in some form either on Internet or with some expert but the fishermen do not have access to this information. The reason for this can be either low level of literacy or lack of communication technology or discomfort in using new technologies.
While on ship as well the fishermen do not have any means to know if they've entered foreign territory or in case they fall sick or if they lose their way or if they face any natural calamity they have no means to ask for emergency assistance.
There is therefore felt a need for a system using which fishermen can collaborate for faster dissemination of information and get advice. There is also felt a need for a single system which will enable the fishermen to get navigation details, emergency assistance and other important Fishing domain related information in their local language and pertaining to their geographical location.
OBJECT OF THE INVENTION
It is an object of the present invention to provide a system to facilitate collaboration amongst fishing communities.

It is another object of the present invention to alert fishermen when they enter foreign territory or in case of emergency.
It is yet another object of the present invention to provide a system for automatic dissemination of fishing domain related information and news to fishermen.
It is still another object of the present invention to provide a multilingual system to assist the fishermen in their local language.
One more object of the present invention is to provide a system which assists semi-literate and illiterate fishermen by providing text based, image based and voice based local language interface to the system.
A further object of the present invention is to provide a single system which assists the fishermen and also facilitates collaboration amongst them.

DETAILED DESCRIPTION
The drawings and the description thereto are merely illustrative of a system to provide assistance and to facilitate collaboration amongst fishing communities and only exemplify the invention and in no way limit the scope thereof.
To provide fishermen with a platform to communicate with other fishermen, get assistance and navigation details while they are fishing in deep sea, get latest updates related to fishing industry and get expert advice; the present invention envisages a system to provide assistance and to facilitate collaboration amongst fishing communities.
The present invention harnesses the ubiquitous power of mobile devices and their inbuilt GPS receivers and accelerometers to provide fishermen with a single interface to assist them and address their issues.
In accordance with one aspect of the present invention, the system provides a social networking and micro-blogging platform which uses multimedia for communication, enabling discussions using text, voice, images and videos. The system provides a very rich but simple multilingual user interface so that anyone with a basic level of education can use it with minimal training. Intuitive icons are provided for easy understanding and selection.
In accordance with another aspect of the present invention, along with social networking, the system acts as knowledge acquisition and information dissemination/sharing medium, especially with the help of channels. Channels enable fishermen to avail services like Potential Fish Zone (PFZ) Assistance, Multimedia Knowledge Gallery, News. Yellow Pages and Weather. Thus, the fishermen can gain information about fishing related best practices and commercial information, read breaking news of their area, browse through

local train and bus time-table and use banks details in their area. It thus enables fishermen to gather valuable information to help them in their day to day activities. Channels also provide fishermen with a platform to connect with experts for addressing their fishing related queries.
In accordance with yet another aspect of the present invention, the system provides alerts to fishermen in case they enter foreign territory. Also, in case of emergency or if the fishermen loses his way the system enables fishermen to find the shortest route to reach the coast. Thus, the mobile device envisaged by the present invention associated with the fishermen ensures that fishermen get assistance in deep sea. In addition, the fishermen get navigation details to the nearest PFZ or navigation details to the nearest shore or territorial alerts in no network zones.
Furthermore, the system continuously checks the battery level of the mobile device when the fishermen is fishing in deep sea and if the battery level is below a predetermined threshold the system alerts the fishermen and only sends necessary updates to conserve the battery charge so that the battery can last till the fisherman returns to the shore / coast.
Referring to the accompanying drawings, FIGURE 1 shows a block diagram of the system 100 to provide assistance and to facilitate collaboration amongst fishing communities. The system 100 consists of two major components including a plurality of mobile devices 102 embedded with a customized application, an in-built GPS receiver and an accelerometer: and a web server 114 co-operating with the mobile devices 102.
Each mobile device 102 further includes application activation means 104 which enables the fishermen to activate the customized application embedded in the mobile device 102. During a first time activation of the customized application, the fishermen are presented with options to setup their preferences. The preferences include language, type of notifications, frequency of notification and the like. Type of notification for instance, includes either voice based notifications or only text based notifications and frequency of notification for instance includes automatically sending updates as they arrive, sending

updates at predetermined time or sending updates only on a predetermined channel activation.
On activation of the customized application the fishermen are presented with a user interface 106 which displays multimedia based cascading menus providing a plurality of channels and their corresponding data for a channel selection by the fishermen on the mobile device 102. The cascading menus are presented to the fishermen in their local language text and with intuitive icons to facilitate easy understanding of the menu and also for ease of use of the fishermen. Moreover, being in the multimedia format, a local language voiceover based on the language preference is associated with each of the icons, thus, when a particular icon of the menu is selected the voiceover is played to inform the fishermen the channel he/she has selected.
The channels provided by the present invention include:
• Potential Fish zone assistance: On selecting this channel the fisherman are guided to a Potential Fish Zone (P.FZ), This channel not only shows the shortest distance the fishermen need to cover to reach PFZ but also displays a real-time two point graph to pictorially show the distance between the current location of the fishermen and the PFZ;
• Territory Alerts: On selecting the Potential fish zone assistance channel the GPS location of a territory around the potential fish zone is compared with the location of the fishermen and the fishermen are alerted in case they are near the water boundaries of a country and approach a foreign territory;
• Emergency assistance: On selecting this channel, the fishermen are guided to the nearest coast in case of an emergency situation. This channel also enables the fishermen to be guided to a desired coast in case they lose their way;
• Multimedia based knowledge library: On selecting this channel the fishermen are provided with a knowledge repository. Here, the fishermen can search for information about various fishing related processes in multimedia form. This knowledge base acts as a library for the fishermen;
• Local weather forecasts: On selecting this channel weather prediction for typically the coming seven days is displayed. The weather information is displayed in

graphical image format for easy reading by the fishermen. The graphical information about cloud coverage, temperature and precipitation is provided for the local region where the fishermen are situated;
• Local news: On selecting this channel news feeds at a district or state level is displayed for the fishermen;
• Multimedia based social networking: On selecting this channel the fishermen can connect with other fishermen to share their views in multimedia formats like voice, video and image. The social networking provides a platform where fishermen can exchange their views and information and get a platform where they can speak out their questions, issues, get new technology information and the like;
• Local fish market information: On selecting this channel the fishermen are provided with information from local fish market;
• Advisory service: On selecting this channel the fishermen are provided a forum where they can ask their questions to an expert. A fisherman can discuss with the expert regarding new fishing techniques that can help them in fishing. This channel also maintains a repository of advices provided by the expert in the question and answer format so that it can benefit other fishermen who are facing the same problem; and
• Fishing related live local feeds: On selecting this channel live RSS feeds are provided to the fishermen. These feeds are displayed in the local language of the fishermen. Also provided in this channel is local information which is required by the fishermen including local bank details, bus timetables, local train timings and the like.
The selection of a particular channel and its associated channel information is sensed by sensing means 108 of the mobile device 102 which co-operates with the user interface 106. The sensed channel selection information and sensed channel data are sent to transmission means 110 which further transmits the sensed channel selection information and the sensed channel data to the web server 114 for further processing. The sensed channel selection information and sensed channel data include for instance, if the channel

is selected as Potential Fish Zone assistance then the sensed channel selection information will be Potential Fish Zone assistance and the sensed channel data will include the current GPS location of the mobile device 102, this sensed data is transmitted to the web server 114 for processing the channel selection,
The web server 114 co-operates with a plurality of mobile devices and includes a receiver unit 116 which receives the sensed channel selection information and the sensed channel data.
The sensed channel data additionally includes battery charge status and acceleration readings of a mobile device in the event that the sensed channel selection information includes channels selected from the group of channels consisting of potential fish zone assistance and emergency assistance but this data is not transmitted to the web server 114 but processed locally by the application embedded in the mobile device 102.
The web server 114 includes a repository 120 which is divided into various categories. These categories enable systematic storage of data for retrieval. The categories for instance include latest fishing market data, latest weather forecasts, latest PFZ information for each of the fishing zones, data on fishing domain, data on latest government reforms and the like and each of these categories are linked to predetermined channels. The web server 114 includes information extraction means 128 which extracts fishing related live feeds and information from predetermined external sources. These external sources can be government websites giving PFZ information, policies, reforms, weather forecasts and the like. The information extraction means 128 passes the extracted live feeds and information to segregation means 130 which then based on the information assigns a category and passes the live feed and information with the appropriate category to the repository 120 for storage.
The data from the receiver unit 116 is given to the processing unit 122. The processing unit 122 is also communicably coupled to the repository 120 for access to the stored information. The processing unit 122 processes the sensed channel selection information

based on the sensed channel data and the fishing domain related data and provides multimedia based processed information.
The multimedia based processed information before transmission is given to a multimedia rendering means 126 which senses the model and configuration of a mobile device and further makes the processed information compatible for display on the mobile device. Thus, eliminating any conflicts and making the system compatible with any model of the mobile devices.
The compatible multimedia based processed information is then passed to a transmission unit 124 which transmits the multimedia based processed information to execution means 113 of the mobile device 102. The execution means 113 receives the sensed channel selection information, the sensed channel data and the multimedia based processed information and uses received information to launch and execute the sensed channel and its related services on the user interface 106.
The user interface 106 co-operates with a multilingual text to speech converter 112 which converts text displayed on the user interface 106 to local language based speech for playing for the fishermen to enable semi-literate and illiterate fishermen to easily use the system.
The web server 114 also comprises auto channel activation means 118 which automatically activates a channel based on predefined preference settings selected by a fisherman during a first activation of the customized application on the mobile device. For instance, if a fisherman selects that he needs fish market related news notifications automatically then the web server 114 triggers the channel selection information to include local fish market information channel for sending automatic real-time updates.
The execution means 113 of the mobile device 102 and the processing unit 122 of the web server 114 performs the task of channel execution and include various sub units as seen in FIGURE 2 and FIGURE 3 respectively.

FIGURE 2 shows the sub-blocks of the execution means 113 and FIGURE 3 shows the various sub units of the processing unit 122 which enable the system 100 to process various channel requests. The detail working of the execution means 113 and processing unit 122 and its sub blocks are explained hereinafter.
Any channel selection information and its related data is given to the processing unit 122 for processing and the processed information is received by the execution means 113 for launching and executing the channel and displaying the processed information on the user interface 106 for the users.
The communication between the web server 114 and the mobile devices 102 can only be established when the mobile devices are in coverage and can send and receive information from the web server 114. However, in the scenario that the fishermen are in deep sea fishing, the chances of the mobile devices catching network coverage are meager. Hence, the present invention provides mobile devices 102 with computational capability to ensure that the mobile devices 102 provide necessary emergency aid to the fishermen even in no network zones.
To facilitate the fishermen with navigation aid and emergency assistance in reaching the nearest shore, the present invention when sensing the channel selection as potential fish zone assistance transmits the current location of the mobile device 102 to the web server 114. The processing unit 122 of the web server 114 receives the channel selection information and via its fishing zone extraction means 300 extracts potential fish zone information based on the GPS co-ordinates from the repository 120, wherein the potential fishing zone information consists of GPS co-ordinates representing a location of the potential fishing zone. Also based on the extracted potential fishing zone GPS co¬ordinates the processing unit 122 determines the GPS co-ordinates of the territory surrounding the potential fishing zone and coast information around that potential fishing zone. For the purpose of determining the GPS co-ordinates of the territory and the coast neighboring a PFZ, the processing unit 122 includes:

• first territory detection means 302 to detect a particular geographical boundary near a selected PFZ, wherein the geographical boundary is represented by GPS co-ordinates; and
• second territory detection means 304 to detect a coast neighboring a PFZ wherein the coast is represented by GPS co-ordinates.
These determined Potential Fish Zone, Territory / Geographical Boundary and Coast GPS co-ordinates are sent to the execution means 113 via the transmission means 110 as multimedia based processed information. The execution means 113 receives these Potential Fish Zone, Geographical Boundary and Coast GPS co-ordinates via its receiving means 200. The receiving means 200 forwards the received GPS co-ordinates to temporary storage means 202 to temporarily store the GPS co-ordinates for enabling the mobile device 102 to provide navigational details and emergency assistance in deep sea when the mobile device 102 is in no network zone. The information in the temporary storage means 202 is re-written each time the execution means receives potential fish zone assistance channel as sensed channel selection information.
Further, for execution of the potential fish zone assistance channel the execution means 113 at predetermined regular intervals receives GPS co-ordinates of a mobile device from the mobile device's in-built GPS receiver as a part of the sensed channel data representing the current location of the mobile devices, the execution means 113 includes fishing assistance means 204. The fishing assistance means 204 further includes:
• path determination means 206 which receives and determines a shortest route
from the current GPS co-ordinates of a mobile device 102 to the potential fishing zone based on the GPS co-ordinates representing a location of the potential fishing zone from the temporary storage means 202;
• map generation means 208 which co-operates with the path determining means
206 and generates a graphical map showing the shortest route between the
current location and the potential fish zone, the graphical map includes a first
point representing current location of a mobile device and a second point
representing a location of the potential fishing zone. The path between the first
and the second point is highlighted for easy reference of the fishermen. The

generated graphical map is provided as processed information for display on the user interface 106;
• updation means 210 co-operates with the path determination means 206 and the
map generation means 208 to determine the shortest route between the current location of a mobile device and the Potential Fish Zone and update the graphical map. The updation means 210 provides an updated graphical map by changing the position of the first point to reflect the current location of the fishermen and this updated graphical map is provided as processed information for display on the user interface 106;
• a comparator 212 which receives and compares GPS co-ordinates representing a
current location of a mobile device with the GPS co-ordinates of a geographical boundary stored in the temporary storage means 202 and provide compared results; and
• alerting means 214 co-operates with the comparator 212 which provides real time
territory alerts as processed information for display on the user interface 106 in the event that the compared results indicate that current location of a mobile device 102 is close to the geographical boundary.
Thus, once the mobile device 102 on activation of the potential fish zone assistance channel receives the Potential Fish Zone, Territory and Geographical Boundary and Coast GPS co-ordinates, based on its current GPS co-ordinate received from the in-built GPS receiver and the computations performed by the fishing assistance means 204 can provide navigational aid in standalone mode, that is without receiving any updates from the web server 114.
Similarly, the execution means 113 includes emergency assistance means 216 which also continuously receives GPS co-ordinates representing a current location of a mobile device from the mobile device's in-built GPS receiver as a part of the sensed channel data in the event that the emergency assistance channel is sensed in the channel selection information. The emergency assistance means 216 includes shortest path determining means 218 which co-operates with the temporary storage means 202 to detect a shortest path based on the current location of a mobile device to the GPS co-ordinates of a coast

and further provides the shortest path in a graphical map format as processed information for display on the user interface 106. Like, in the fishing assistance means 204, the emergency assistance means 216 also includes a map updation means 220 to update the graphical map based on the current location of a mobile device to the coast and display the map on the user interface 106.
In accordance with the present invention, the frequency of the updation of the map in the fishing assistance means 204 and the emergency assistance means 216 depends on the number of fixes. These fixes are typically dependent on the user and the battery status of the mobile device 102.
The execution means 113 further includes detection means 222 to detect battery charge status and acceleration readings of a mobile device as a part of the sensed channel data in the event that the sensed channel selection information includes channels selected from the group of channels consisting of potential fish zone assistance and emergency assistance. The detected battery charge status and acceleration readings of the mobile device 102 are passed to battery status checking means 224 which uses the battery charge status and accelerometer readings to calculate remaining duration of a mobile device's battery and determines if a mobile device 102 has enough battery charge to sustain a round trip. The battery status checking means 224 is only invoked by the execution means 113 in the event that the sensed channel selection information includes channels selected from the group of channels consisting of potential fish zone assistance and emergency assistance. This battery status checking means 224 co-operates with battery alert creation means 226 which disables transmission of processed information or reduces the frequency of updates and generates a low battery alert as processed information for transmission to the mobile device based on predetermined thresholds. The battery alert creation means 226 based on the calculated remaining battery duration also notifies to the fishermen the number of updates that is, the navigation updates that can be displayed in the remaining battery duration. This is to ensure that the fishermen have enough battery charge to sustain a round trip and are not left unassisted in deep sea.

Typically, while fishing in deep sea, battery drainage is bound to happen as a network operator of the mobile device will try to connect to different towers to catch network, which will drain the battery more, so to reduce it the present invention enables the fishermen to themselves turn on a flight mode as and when necessary. The system envisaged by the present invention can itself turn on the flight mode if possible after some fix points. To achieve conservation of battery charge, the battery status checking means 224 records the battery level at the start of a channel. This battery level is recorded as BO and the time at which a channel is started is recorded as Tl. Using the battery alert creation means 226 if the battery level is low then fisherman is shown an alert notifying him that handset has insufficient battery to get assistance.
For instance, if fish zone assistance channel is selected. If handset has sufficient battery then after an interval user interface 106 will be refreshed and this time is recorded as Tl and updates D are sent to the fisherman. These updates are typically the updates to the graphical map showing the direction and distance between fishermen's current location and the PFZ. The battery level is again noted at this point and recorded as Bl. Thus, to calculate how much battery is drained in a single fix where fix indicates the process of getting GPS value and refreshing screen with updated graph and D.
The battery status checking means 224 uses the accelerometer readings to get the velocity (V) with which the fisherman is moving. The distance that needs to be covered and velocity with which the fisherman is moving is known and using these values the battery status checking means 224 calculates how much time the fishermen will require to reach PFZ. The total time for which handset battery will work is calculated as Tf=2[D/V+(Tl-T0)].
The value is taken twice as a round trip is considered that is, both going and returning durations. The amount of battery drained to do one fix that is. get the GPS value, display the graph and the update is proportionate to B0-B1. Using these values battery status checking means 224 calculates a remaining duration of the battery charge / how many fixes can be done and further forwards the remaining duration information to the battery alert generation means 226. The battery alert generation means 226 uses the value

calculated for amount of battery drain estimate to do one fix to determine the total number of fixes / updates.
