Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to the field of computer systems and database technology. More specifically embodiments of the present invention relate to the field of portable electronic devices, such as personal digital assistants (PDAs), cell phones, pagers, etc. 
     2. Related Art 
     Recent miniaturization of electronic components has led the way to the reduction in size of almost all electronic components. Reduction in the size of electronic components resulted in physically smaller sized electronic devices. Manufacturers of the electronic components, at the same time, took the opportunity to add new features to the same or even to the reduced sized electronic devices. 
     Electronic organizers were introduced to the market more than two decades ago. These devices were commonly used to store and maintain address books, telephone listings and daily activity schedules albeit with limited number of records due to limited storage capacity. Subsequent development of such devices introduced limited capability calculating functions, weekly and monthly scheduling “to do lists” and business card files. The most noticeable developments in this family of devices, in the recent years, are increased memory size, reduced physical size, communication capabilities and increased functionality. 
     The emergence of Personal Digital Assistant, commonly known as PDA, introduced a new type of organizers. The PDA&#39;s have capability to store telephone numbers, addresses, daily appointments and software that keeps track of business or personal data such as expenses. Furthermore, the present PDA&#39;s have the capability to synchronize to a personal computer, thus enabling the two devices to exchange updated information together. Additionally, the PDA can connect to a modem, enabling it to have electronic mail (e-mail) capabilities. Another recent development in PDA technology is capability to browse Web pages located on the Internet and synchronize, e.g., HotSync, with another device or with a compatible personal computer. Moreover, an advanced PDA can have Internet capabilities to communicate over a wireless interface. (e.g. radio interface). 
     A typical PDA user often uses the device during a business meeting. The user can easily access his/her customized telephone directory, schedule business activities, send and receive e-mails, and connect to the Internet, etc. 
     More advanced PDA devices, such as hand-held computer systems, each have the capability to wirelessly exchange certain category of information such as an electronic business card. For example, in a business meeting, one needs not hand over a conventional paper business card to another participant in the meeting. If both parties own handheld computers, exchange of business cards can be accomplished electronically and wirelessly. In such situations, one requests a business card from another and the other party positions his/her handheld computer device facing that of the requester&#39;s and by push of a button simply beams an electronic version of his/her business card to the requester. 
     Presently, the distance between the two devices limits a successful transmission of information. The distance between a transmitting device and receiving device cannot be more than a few feet or maximum of three yards. Limitation of distance for a successful exchange of electronic business cards is one shortcoming in the available devices. 
     Generally the exchange of electronic business card is completed once the sender of a business card beams his/her card to the other person&#39;s handheld device which is ready to receive the information. However, If the sender of the electronically beamed electronic business card desires to receive the other party&#39;s electronic business card, then the entire process must be reinitiated. Available devices require two different user initiated transmissions and therefore two different sets of user initiated transactions for a bilateral exchange of business cards. Requirement of two sets of user initiated transactions to exchange business cards between two associates in and of itself is another shortcoming to the present systems. 
     User convenience is a very important factor for portable electronic devices. Typically, portable electronic devices are employed while the user is on the run, e.g., in business meetings, on business travel, personal travel, in a vehicle, on foot, etc. Because the user may be occupied or busy while using the portable electronic device, the number of user steps or user tasks required in order to access information from an electronic device (or to store information into the electronic device) is crucial for producing a commercially successful and useful product. That is, the more difficult it is to access data from an electronic device, the less likely the user will perform those tasks to obtain the information. Likewise, the easier information is to obtain, the more likely the portable electronic device will be used to obtain that information and the more likely the portable electronic device will become a part of the user&#39;s everyday activities. 
     Therefore, by requiring two user initiated steps to perform an electronic business card swap, it is possible that many users will not perform a full exchange because the first receiver of the business card does not wish to manually go through with the trouble of initiating the last transfer of information. This may be because the first recipient is on the run, late for another meeting, or simply does not want to go through the manual processing of sending his/her business card to the first sender. 
     SUMMARY OF THE INVENTION 
     The present invention enables an owner of a handheld electronic device to receive a business card from another device and send his/her electronic business card to other party&#39;s device in one transaction. An embodiment of the present invention enables the users of these devices to exchange business cards automatically and with user initiation from only one party. For example, in a business meeting, an owner of one handheld device beams his/her business card to the owner of another&#39;s device and the receiver device selectively and electronically responds. The receiving device receives the signal from the requester and if the receiving device is in “RECEIVE AND AUTOMATIC RESPONSE” mode, it will receive the electronic business card, file the information and automatically send a responding business card to the requester who initiated the process. However, if the recipient device is set to “ACCEPT NO RESPONSE” mode, the receiving device will receive and file the business card but does not send a corresponding business card in return. Furthermore, a device may be set in “REJECT” mode; in which case the receiving devices neither accepts nor transmits an electronic business cards. 
     The present invention discloses a method and a system for selective exchange of electronic business cards, calendar information and general data structure between handheld computer systems. Furthermore, the present invention discloses a wireless exchange of the above-mentioned information by means of infrared communication or a communication mechanism, which is substantially compatible with a Bluetooth communication protocol. 
     A method and system are described of automating two way transmission of information from one handheld electronic device to another handheld electronic device. Specifically, the present invention discloses a method and system for selectively transmitting information, e.g., business cards, calendar appointments and general data structure, from one device to a requesting device. The receiver makes the selection of a response. The receiver accepts the information, accepts or transmits information of the same category, or rejects the information based on a user choice. If the user selects the RECEIVE AND AUTOMATIC RESPONSE option, the device automatically sends information requested to the receiver both to the sender so that the two way transmission appears as one integral transmission between the users. In one embodiment, the data to be exchanged is business cards and the devices are portable handheld computer system. 
     In one embodiment, a method for communicating certain category of information is disclosed. The disclosure describes an electronic device transmitting a category of information to an another device. The receiving device receives the information and displays the type of response it will communicate to the first device. The receiving device responds to the sending device information of the same category. 
     Furthermore, an embodiment of the invention discloses a handheld device implemented two-way beaming of electronic business cards, calendar information and executable programs. The embodiment uses a dialog box in each of sending and receiving devices. The dialogue box enables the users to set the response in their respective devices. Based on this setting the system will selectively and automatically responds to a requester. A device receiving a request for transmission of a business card, will decide, based on the set mode, to accept the information without a response, reject the information received, or accept and store the information and transmit information of the same type automatically.

     In particular, the PDA can be used to browse Web pages located on the Internet. The PDA can be coupled to a networking environment. It should be appreciated that embodiments of the present invention are well suited to operate within a wide variety of electronic systems (e.g., computer systems) which can be communicatively coupled to a networking environment, including cellular phones, pagers, etc. 
       FIG. 1  is a block diagram of an exemplary network environment  50  including an exemplary personal digital assistant. The PDA  100  is also known as a palmtop or palm-sized electronic system or computer system. The PDA  100  has the ability to transmit and receive data and information over a wireless communication interface (e.g., a radio interface). The PDA  100  is one exemplary implementation on which the present invention can operate. The present invention can operate on any portable electronic system or device. 
     In one embodiment, base station  32  is both a transmitter and receiver base station, which can be implemented by coupling it into an existing public telephone network  34 . Implemented in this manner, base station  32  enables the personal digital assistant  100  to communicate with a proxy server computer system  36 , which is coupled by wire  35  to the existing public telephone network  34 . Furthermore, proxy server computer system  36  is coupled to the Internet  52 , thereby enabling the PDA  100  to communicate with the Internet  52 . It should be further appreciated that other embodiments of a communications network may be utilized in accordance with the present invention. 
     The data and information which are communicated between base station  32  and the personal digital assistant  100  are a type of information and data that can conventionally be transferred and received over a public telephone wire network system. However, a wireless communication interface is utilized to communicate data and information between the PDA  100  and base station  32 . It should be appreciated that one embodiment of a wireless communication system in accordance with the present invention is the Mobitex wireless communication system. 
       FIG. 2A  is a perspective illustration of the top face  100   a  of one embodiment of the palmtop computer system. The top face  100   a  contains a display screen  105  surrounded by a bezel or cover. A removable stylus  80  is also shown. The display screen  105  is a touch screen able to register contact between the screen and the tip of the stylus  80 . The stylus  80  can be of any material to make contact with the screen  105 . The top face  100   a  also contains one or more dedicated and/or programmable buttons  75  for selecting information and causing the computer system to implement functions. The on/off button  95  is also shown. 
       FIG. 2A  also illustrates a handwriting recognition pad or “digitizer” containing two regions  106   a  and  106   b . Region  106   a  is for the drawing of alphabetic characters therein (and not for numeric characters) for automatic recognition, and region  106   b  is for the drawing of numeric characters therein (and not for alphabetic characters) for automatic recognition. The stylus  80  is used for stroking a character within one of the regions  106   a  or  106   b . The stroke information is then fed to an internal processor for automatic character recognition. Once characters are recognized, they are typically displayed on the screen for verification and/or modification. 
       FIG. 2B  illustrates the bottom side  100   b  of one embodiment of the palmtop computer system. An optional extendible antenna  85  is shown and also a battery storage compartment door  90  is shown. A communication interface  108  is also shown. In one embodiment of the present invention, the communication interface  108  is a serial communication port, but could also alternatively be of any of a number of well known communication standards and protocols, e.g., parallel, USB, SCSI, Firewire (IEEE 1394), Ethernet, etc. It is appreciated that interface  108  can also be used for charging current when using rechargeable batteries. 
       FIG. 3  is an exploded view of the palmtop computer system  100  in accordance with one implementation. System  100  contains a front cover  210  having an outline of region  106  and holes  75   a  for receiving buttons  75   b . A flat panel display  105  (both liquid crystal display and touch screen) fits into front cover  210 . Any of a number of display technologies can be used, e.g., liquid crystal display (LCD), field emission display (FED), plasma, etc., for the flat panel display  105 . A battery  215  provides electrical power. A contrast adjustment (potentiometer)  220  is also shown. On/off button  95  is shown along with an infrared emitter and detector device  64 . A flex circuit  230  is shown along with a PC board  225  containing electronics and logic (e.g., memory, communication bus, processor, etc.) for implementing computer system functionality. A digitizer pad can be part of the display assembly or it can also be included in PC board  225 . A midframe  235  is shown along with stylus  80 . Position adjustable antenna  85  is shown. 
     A radio receiver/transmitter device  240  is also shown between the midframe and the rear cover  245  of  FIG. 3 . The receiver/transmitter device  240  is coupled to the antenna  85  and also coupled to communicate with the PC board  225 . In one implementation, the Mobitex wireless communication system is used to provide two way communications between system  100  and other networked computers and/or the Internet via a proxy server. In other embodiments, TCP protocol can be used. 
       FIG. 4  illustrates two-way beaming between two devices. The number of devices transmitting information is not limited to two devices. A requesting device sends and receives information through a wireless communication interface  108 , which ca be bluetooth or IR in one example. 
       FIG. 4  illustrates the two-way automatic beaming session.  FIG. 4  configuration depicts a first device (i.e. the top device) sending information of certain category to a second device, (i.e.) bottom device, which receives the information and automatically transmits information of the same category to the first device. For example the owner of the top device initiates the transmission by sending his/her business card and the bottom device receives the business card, files it and automatically sends the business card of its owner in return. 
       FIG. 5  illustrates the flow diagram implementing a dialog session to set the mode for selective two-way beaming of the information. To set the mode the screen is turned on. Once the screen is turned on for the initial implementation, the IR device, which is attached to the serial port  108  of the receiving device, continuously looks for an IR signal. At the step  520 , once a IR signal is detected, a piece of software called the serial manager gets the entire transmitted communication form the transmitting device and the receiving device parses the received information. At step  520 , the system stores the data received in cache memory and displays a message on the screen indicating receipt of data. 
     During this user interface, the user is presented with the screen depicted in  FIG. 6 . At this stage the user of the receiver device can select one of the following three modes of option. The user can select step  530  in which case the receiver device will not accept any incoming data and will transmit no response. If the user selects step  540 , the receiver device will accept the incoming information but it does not transmit a corresponding response. However, if the user wants to receive the incoming request and automatically respond to the sender with the information of the same category, step  550  is chosen. Step  550  is the object of this invention, whereby the receiver system receives the information of a particular category and automatically sends back the information of the same type to the one who initiated the process. In one example, the receiver device accepts an electronic business card from a sending device and upon the user selecting choice  550 . 
       FIG. 6  illustrates the display screen  105  view of a receiver device during a dialogue session. Upon receipt of the first transmission, the screen displays three different mode settings and the owner of the device can select and set the device for one of the following modes: ACCEPT &amp; AUTOMATIC RESPONSE  610 , ACCEPT NO RESPONSE  620  or REJECT  630 . The receiving and responding devices each can have a dialogue box and each can be set to the desired mode for two way automatic beaming before the selective and automatic exchange can be accomplished. 
       FIG. 7  illustrates screen  105  when application icon  88  is tapped. The system is ready to beam the user&#39;s electronic business card. In one mode of operation, the two way-beaming processes require both devices, the receiving and transmitting devices to have BEAM BOX  240  of  FIG. 3 . Tapping on “BEAM BUSINESS CARD” choice causes the transmission of the information. 
     Alternatively, the user can simply hold down phone icon  710  for 1–2 seconds to initiate two-way beaming. 
       FIG. 8  illustrates an operating system screen  105  where the owner of the device is given the choice of a response upon reviewing of the electronically received information. The user can use the screen of  FIG. 8  to program preferences for the two-way beam process. 
     The owner of the device can select “AUTOMATICALLY SEND SAME CATEGORY RESPONSE”  810 , in which case the device does not wait for the owner&#39;s decision for response and sends information of the same category back to sender automatically. In this case, the user is not presented the choices of  FIG. 6  but rather selection  610  is automatically assumed as default. 
     If the owner of the device selects the “CUE THE USERS” mode  820 , the device will receive the information and keeps it in cache memory. Screen  6  will then be and the owner can choose one of the choices in  FIG. 6  menu.
