Context Aware Chat Management

DESCRIPTION TECHNICAL FIELD OF INVENTION The invention generally relates to the field of context awareness. More particularly, the invention relates to methods and devices for context-aware chat management. BACKGROUND OF INVENTION At present, chat services have become very popular as they offer instantaneous transmission of chat messages from a sender to one or more receivers through a network, Near Field Communication (NFC), or the Internet, etc. A typical chat message may include text, image, audio, video, location, contact, or the like. Chat services may involve direct communications between individuals, or may involve group communications, wherein communication occurs from one sender to many receivers. In any chat service, a user has access to contact list that includes the names or identifications of other users with whom communication may be desired in the future. When users identified in the contacts list connect to the network, the user is notified of their presence, so that an interactive chat session may begin, if desired. During the interactive chat session, the instant messages between users are contemporaneously routed to the users' electronic devices and displayed on a pop-up window or display area of a display screen. In this way, two or more users may converse with one another in a simulated real-time manner through messages. The unique features of instant messages (as opposed to email and forum posts, whether public or non-public) provide users with the ability to engage in a near realtime conversation, which is appealing to users. 2 SUMMARY OF INVENTION This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended as an aid in determining the scope of the claimed subject matter. The problem with current chat services is the inefficient management of chat messages because the number of chat messages in a chat session can sometimes be huge. While chat messages are typically sorted according to the increasing order of time, i.e., from past to present, and displayed in top to bottom fashion in the chat session; in order to see an old message which is not displayed on a current screen and is undeleted, a user needs to continuously scroll up the chat session. This may be time consuming and boring for users. To this end, the present invention provides a solution for improving the management of chat messages. Embodiments of the present invention basically provide context-aware chat management. It is observed that there can be mini-conversations inside a long chat session, these mini conversations have associated artefacts that help in establishing context and supplementing the conversation. Accordingly, a chat session can be segmented into various contextual groups, which can be expanded or collapsed as and when required, for example, by zooming in and zooming out respectively, a pinch open gesture and pinch closed gesture respectively, clicking an expand button and collapse button respectively, etc. In one implementation, the context can be established automatically. Alternatively, the user can manually change the context or initiate a new context. Once context is known, the same can be indicated along with the one or more chat messages and/or a chat session. In one implementation, readymade chat objects can be sorted according to known context for facilitating easy selection by user. 3 The advantages of the present invention include, but are not limited to efficient management of chat messages, a new interaction to retrieve contextual groups in a chat session, utilization of context awareness to provided new functionalities, etc. Furthermore, a reader’s attention is focused clearly on context due to these segmented chunks and has most relevant artefacts, such as pictures, documents, etc. to support his conversation. The details of one or more embodiments are set forth in the accompanying drawings and description below. Other features and advantages will be apparent from a reading of the following detailed description and a review of the associated drawings. It is to be understood that the following detailed description is explanatory only and is not restrictive of the invention as claimed.

In a further embodiment, the user interface (102) is configured to display an alert in the at least one contextual group upon receiving a new message in that contextual group. Figure 2 illustrates an exemplary method (200) implemented in a chat application for context-aware chat management. In one embodiment, the method (200) comprises: creating (201) at least one contextual group in an ongoing chat, the at least one contextual group comprises one or more messages having same context; displaying (202) the at least one contextual group in the ongoing chat; and performing (203) an action with the at least one 9 contextual group in response to a user command, wherein the action comprises: expanding the at least one contextual group, or collapsing the at least one contextual group. In a further embodiment, the method (200) comprises: automatically establishing (204) a context for the one or more messages in an ongoing chat. In a further embodiment, the at least one contextual group is automatically created in accordance with the automatically established context. In a further embodiment, the method (200) comprises: receiving (205) a user input for manually initiating or changing a context in the ongoing chat. In a further embodiment, the at least one contextual group is created in accordance with the manually initiated or changed context. In a further embodiment, the method (200) comprises: displaying (206) an icon corresponding to the context along with the one or more messages. In a further embodiment, the method (200) comprises: sorting (207), based on the context, a plurality of objects which can be inserted in the ongoing chat; and displaying (208) the sorted objects in the chat application to facilitate user selection. In a further embodiment, the method (200) comprises: displaying (209) an alert in the at least one contextual group upon receiving a new message in that contextual group. Subsequent paragraphs explain the present invention using examples of contextual chat in healthcare, i.e., a chat between a doctor and a patient through a medical chat application. Those skilled in the art will appreciate that it is not be construed as a limitation on the scope of present invention, the same is applicable to any chat application, standalone chat program, or web based chatting. 10 Figure 3 illustrates an exemplary scenario (300) for interaction in a contextual healthcare chat that can be used to retrieve contextual groups in a chat session. Figure 3(a) illustrates a normal chat session having detailed textual messages, pictures, vitals, symptoms, etc. The user can provide a user input (301) to group the messages based on contexts, for example, OPD visit 1 follow up, prescription queries, and so on. In this way, it will be easier to search for a message by collapsing and/or expanding the long conversations thread, and then scrolling up (302) and/or scrolling down (303) as shown in Figure 3(b). Figure 3(c) illustrates that a user can pinch out (304) or tap to zoom in on any of the contextual group of chats, i.e., a chat block (305). As illustrated in Figure 3(d), this user action will bring back the details (306) in the chat session with focus on that particular contextual group (305). Figure 4 illustrates an exemplary scenario (400) for manual change of context in a chat session. More specifically, Figure 4a illustrates that a user can provide user input (401) on an artefact for manual changing the context or starting a new context altogether. As shown, said user input (401) changes the context to ‘Reports’ (402) as shown in the Figure 4b. A contextual group may be created based on the manually changed context or the newly started context. Figure 5 illustrates an exemplary scenario (500) for user initiated context detection. As per the invention, the context of chat changes as per the communication automatically and this helps in segmenting the chat thread in various contextual groups. In one example, the user can select an attachment (501) to be sent in the chat session as shown in Figure 5a. The attachment may be a report (502) as shown in Figure 5b. When this report is sent as an attachment in the chat, there is change in the context (503) reflected in the user interface as shown in Figure 5c. A contextual group may be created based on said context (503). Figure 6 illustrates an exemplary scenario (600) for auto-detection of context in a chat window. Continuing with previous example, the figure shows the change of context 11 (601) as automatically received at the Doctor’s end when the patient sends a report. Consequently, a contextual group is created at Doctor’s end based on said automatically established context (601). Figure 7 illustrates an exemplary scenario (700) for reflection of chat contexts in a dashboard. In one example, the context of the current chats is reflected on a doctor’s dashboard. As illustrated, the regular icons (701) go through a flip animation effect to show the context (702) of the chat along with the appointment type. In one implementation, an alert may be displayed in a contextual group upon receiving a new message in that contextual group. Figure 8 illustrates an exemplary scenario (800) for prioritization of emoticons based on the context. In one example, emoticons/Stickers may be prioritized based on a patient’s chief complaints and symptoms. As illustrated, based on the type of the chief complaints of the patient, the emoticons/stickers are re-arranged and shown in a preference order such that those which are more relevant to the complaint/symptom being pointed out by the patient are shown first. Similarly, any artefacts or external objects, such as images, videos, audios, contacts, locations, or the like that can be inserted in the chat session are sorted according to established context and displayed accordingly. This facilitates quick selection of the artefacts/external objects, hence enriches overall user experience. For example, if two friends are chatting about a person having name XYZ and one friend wants to send the contact details of XYZ in the chat session, then the contact list is automatically sorted based on the identified context. That is, all the contacts having XYZ in their name will appear first in the sorted contact list. In this way, the effort otherwise required in locating the XYZ’s contact details in the contact book is saved to a very large extent. 12 Embodiments of the invention have been described in detail for purposes of clarity and understanding.
