## Background
FIELD OF THE INVENTION
This invention generally relates a language independent real time communication device and method in healthcare domain. More particularly, it relates to a mobile communication device with a language independent keypad capable of acting as real time communication device in healthcare domain.
BACKGROUND OF THE INVENTION
In the growing healthcare domain, it is desirable to have devices that will allow a user to communicate effectively with a doctor or a hospital environment irrespective of language and region. The healthcare facilities in rural areas need to be developed for improving the health status of people in developing or developed countries. Improvement in the healthcare domain can be achieved by making the medical facilities available to rural areas as well. However there are certain limitations in the widespread use of the medical facilities in rural areas. One of the significant limitations is illiteracy or the non-knowledge of a common language like English.
In healthcare domain, the patient needs to communicate effectively with the doctor or any other caretaker, who might be located at different parts of a country or region. Normally different people from different region speak different languages. As the people in the rural areas or people residing in different parts of the country may not be able to understand the language of communication of the doctor, establishing effective communication between the caller and the doctor, nurse or any other care taker will be difficult. Further in case of emergency the doctor should be conveyed correctly about the severity or urgency of the situation. Most of the time communication is not carried out effectively mainly due to different languages of interaction.
Mobile communication devices have solved the problem of communication to a certain extend and some of the mobile communication devices have the flexibility of adapting to different languages. However normally the mobile phones/communication devices will have soft keypads for language selection. But the visual indicium of the keypad will not change even after the mobile phone is configured to work for a selected language. Adapting to a different language from an in-built language will require special knowledge about the functionality of the mobile phone. So an illiterate person may not be able to efficiently use the existing cell phones.
Thus there exist a need to develop an effective language independent real time communication method and device in healthcare domain. The communication method should be implemented taking care of the illiterate rural population.

FIGS. 6A and 6B diagrammatically shows the principles of electronic ink technology that may be used in the device of the present invention. For operation of keypad, it is necessary to provide an indicium for each of the keys indicating to the operator the data or function attributable to each of the keys or the nature of the indicators. A flexible electronic ink film is applied over the keys to provide indicium for each of the keys. An electronic ink film would similarly be applied adjacent to indicators. Electronic ink film may be covered by a flexible protection layer (not shown), if desired, to lend durability and a longer service life to keyboard.
The electronics ink film may utilize thin film transistor (TFT) technology in which plastic transistors are printed on to a thin film of plastic for use in controlling a layer of pigmented microcapsules that are changed from a first color to a second color and back by using small electrical charges controlled by the plastic transistors. A form of electronic ink is shown in FIGS. 3A and 3B that diagrammatically depicts electronic ink microcapsule 622 sandwiched between two layers of thin film transistors 624 and 626 that are charged with a positive or negative polarity, respectively. Microcapsule 622 is filled with a blue or similarly colored ink 628, within which white, electronically charged, balls, chips, or similar elements 630 are suspended.
In the example shown in FIGS. 6A and 6B, negatively charged balls 630 react to the charges of thin film transistors 624 and 626. As depicted in FIG. 6A, thin film transistor layer 624 has a positive charge that attracts the white balls 630 to the top of microcapsule 622, thus making it appear white when viewed from the top. Conversely, in FIG. 3B, thin film transistor layer 626 has a positive charge and the white balls 630 are attracted towards thin film transistor 626, thus exposing the blue ink 628. This makes the microcapsule 622 appear blue when viewed from the top. By employing a plurality of the microcapsules 622 in the layer, as operated by the thin film transistor layers, indicium for the keys and indicators may be formed from the microcapsules contained in film. Thin film transistor layers 624 and 626 can be operated by conductors in a printed circuit board.
Advantages of electronic ink technology include a superior look featuring high contrast, a wide viewing angle, and legibility in low light. Indicium formed from electronic ink consume no power except when the indicium are being changed and allowing the indicium to remain in a visually perceptible form when the power is turned off. Additional information about electronic ink technology usable with embodiments of the present invention is provided in U.S. Pat. Appl. Ser. No. 11/398248, entitled “Apparatus Having User Input Device with Changeable Indicia”, filed on Apr. 5, 2006, the contents of which are incorporated herein by reference in their entirety.

The call may be routed via the server 720, wherein the server 720 will be able to identify the available doctor/recipient 740 and the language on which the doctor/recipient 740 would prefer to have communication. Accordingly the server 720 will direct the call to the doctor/recipient 740 in a first set of pre selected language, the first set of pre selected language being selected by the doctor/recipient 740. In an embodiment the call is conveyed to the doctor or any recipient in text and voice format, wherein the language of the text and voice is in the first set of pre-selected language. The doctor/recipient 740 may also have a mobile communication device 760 with a language independent keypad, in which the selected keys are programmed to perform a pre-defined function. As explained earlier the recipient may program a key to send a message to the patient by actuating a key which is programmed to perform the same function. The recipient may select a second set of pre-selected language in which the recipient will receive message from the caller aurally and in text format.
The patient/caller 730 is allowed to convey a predefined function or a predefined data by actuating a key which has a visual indicium of the function to be performed or data being represented. In an example a key may be configured to send an SMS to the hospital. When the key is actuated by the patient/caller 730, a predefined message in text or voice format is sent to the server 720. Once the key is actuated the message is sent to the server 720. The server 720 will identify the mobile number of the patient/caller 730 from the message. The server 720 will retrieve the patient data. According to the past medical history, availability of the relevant hospital staff and the emergency of the situation the call will be allocated to a recipient. As mentioned earlier the call is conveyed to the recipient in text or voice format is a second set of pre-selected language.
Once the doctor/recipient 740 receives the call, the doctor/recipient 740 replies to the patient/caller 730. For example the doctor may reply to the patient/caller 730 saying that “Take the Medicine XXX”. This message will be conveyed to the patient/caller 730 in a second set of pre-selected language. The message is conveyed as text message as well as voice message.
A communication channel 750 is used for communicating using the mobile phone 760. In an embodiment the severity of the situation is conveyed by different rings tones of different modulation frequency. In an alternative the severity may be conveyed by different forms of vibrations or by increasing the ringing volume of the mobile phone 760.
In another embodiment the device can have different programmable/configurable “severity indices” configured to indicate or represent the severity of the situations/patient. The indicators may be provided with an indicia to configure the visual indicium of the labels affixed near to the indicators to display the nature of the indicators. Alternately the indicators may be configured to display or send different colors to indicate the severity. The severity may be conveyed visually or aurally.
FIG. 8 is a flow chart indicating a method of communicating in a healthcare domain using a mobile communication device with a language independent keypad as described in an embodiment of the invention. In an embodiment the invention provides a method 800 of communicating language independently in a healthcare domain. At step 810, at least a selected plurality of keys in the keypad is configured for representing a visually perceptible indicium for each of the selected keys indicative of an item of data or function represented by the keys. An indicia is used for altering indicium for the selected plurality of keys and/or indicators from a form suitable for use in one language to a form suitable for use in another language and/or to select images or pictures indicating nature of a predetermined item of data represented or a predefined function of a key. At step the 820, at least one key is programmed for performing a predefined function or to represent a predetermined item of data. A processor is provided for programming the keys. At step 830, the predefined function or predetermined item of data is conveyed to a hospital by actuating the keys representing corresponding indicium. The visual indicium of the keys may be in the language known to the user or may be represented by standard icons, images or pictures. Thus if a key is programmed to call up the hospital by actuating that key the user may call up the doctor directly. The key visually represents the “+” symbol to call the doctor. Similarly different keys, which are pre-programmed to perform different functions or to represent predetermined data may be actuated for carrying different functions. In an example a key may be stored with some data, the actuating the key will send a short message to the hospital/doctor saying that the patient is having a “Chest pain”. In emergency the user need not have to call up the doctor or to send an SMS, instead he may actuate the key programmed for sending an SMS to the doctor. At step 840, a job is allocated based on the actuated key to at least one recipient through a server located at the hospital. The server is fed with the patient information and the hospital staff information. The job is conveyed to the recipient aurally as well as in the form of text message. The recipient is given an opportunity to select a first set of pre-selected languages, on which the message needs to be conveyed. At step 550, the recipient responds to the caller. The caller may select a second set of pre-selected languages, on which the reply may be conveyed. The reply may be conveyed as a voice message or as a text message.
The above-description of the embodiments of the device 100, mobile phone 500, the method 800 have the technical effect of communicating language independently in a healthcare domain. The language independency will allow the flexibility of connecting the rural population to a hospital in the urban area without actually knowing the language prevalent in the urban area.
In an embodiment a detachable and configurable user input with changeable indicia to a mobile communicating device is provided. A selected plurality of the keys may be programmed to perform a specific function, performed by easily recognizable display of those services in the form of icons or images. In an embodiment the area information or the GPRS to the request to the respective service is noted to identify the location of the caller and this will act as a crucial information in case of road accidents or any other emergencies. The message from the caller is recorded and conveyed to the recipient and the chances of loosing the information is low. In addition a voice recognition system is provided in association with the server for recognizing the voice of the patient. In an embodiment the device, or the mobile phone is protected with a password. The password can be selected in any language or by using different images or icons.
The various applications of the invention include effective handling of emergency situations like road accidents. It acts as a two way real time communication of “Health alarm” to a family physician or nursing staff by a rural community. The invention will allow telemedicine and will provide tremendous opportunity for medical tourism.
