Title: Communications device and supporting network

Description:
BACKGROUND OF THE INVENTION  
      This invention relates to hand held communication devices and, in particular, to a small self powered personal data storage and communication device capable of storing, sending and receiving packets of preset text, pictorial information or the like, such as names images, phone numbers, email addresses, greetings and messages etc. The invention further relates to means for operation of and navigation through device functions.  
     PRIOR ART  
      There are in existence a wide variety of hand held devices for storage of data and which are capable of down loading or uploading data between compatible electronic devices. Examples of these devices are personal organizers, hand held computers&#39; calculators, mobile phones, measuring instruments and remote controllers for audio. These are effective in receiving and down or uploading data and in limited processing activities. They are generally key or stylus operated but must be a minimum size dictated by the screen size.  
      The size of known devices is also limited by ergonomics of manual use which sets predetermined minimum dimensions for the display and particularly the method of key entry and navigation. Smaller devices than the PDA&#39;s are known but as devices become smaller there may be compromises to functionality. An example of this is the hand held game device These devices usually include a small casing which houses a screen and includes a power supply, electronics control buttons. The buttons allow a player to operate the device functions and are usually located remote from the screen and usually at the sides or below the screen. The buttons must be spaced sufficiently to allow the users finger to operate one button only at a time but the need to space the button for ergonomic advantage places limits on the minimum size possible for the device. If the buttons are too close to the screen, the users finger may partially obscure the screen. There are however devices which rely on screen pressure to active the device using a touch screen. These may be overlaid over the screen but suffer from the problem that the screen display is partially obscured.  
      An example of a prior art electronic data receiving device is disclosed in GB 2 299302 which teaches a device including a casing, a display screen and a touch sensitive panel which faces away from the user when the display screen faces the user. The touch panel preferably, may be variable with respect to the screen display, and may be sensitive to contact or proximity of the users finger. According to the invention disclosed in that patent, the user has an uninterrupted view of the screen because the device is operated from the back by pressure with a users finger. The device may be operable using thumbs on top and fingers underneath. GB 2 299 302 specifically teaches the use of buttons proximity switches which are adjacent or underneath but not superimposed over the display screen. In fact GB 2 299 302 teaches away from using operating means superimposed on a device screen. This approach results in an increase in the physical size of the device as there must be room for the screen and also room for the buttons, pressure sensitive panels or proximity switches remote from the screen.  
      Another known device is disclosed in U.S. Pat. No. 6,049,796, which teaches a method of searching data on a personal digital assistant having an input means, file storage means, a data base, a search engine, display and electronic communication means. The device described is essentially a personal organiser which a user operates by activating search keys remote from the screen. The device is relatively large within the context of hand held devices and has a high storage capacity. As the function/search keys are remote from the screen display this contributes to the physical size of the organiser. The device does not teach the use of a sequence of inputs applied to a screen in order to reduce the size of a device for hand held use.  
      Other known hand held devices allow transmission of text messages. Text messaging is extremely popular within certain sections of the community and is usually conducted using the mobile or cellular phone network with the users&#39; phone handsets being the usual mode of sending and receiving the messages. The prior art teaches all of the above functions in hand held devices such as mobile phones linked to a cell network. In the case of mobile phones the messaging is effected by use of buttons which operate screen functions. The smallest prior art hand held devices have a minimum size dictated by the size of the screen display and the means to operate the device and enter and process data. These functions of display and operation are usually separate and necessitate a presentation surface area which can accommodate each facet of display and operation. This increases the overall size of the device.

       FIG. 2   a  is a front view of a communication device  10  according to an alternative embodiment of the present invention.  FIG. 2   b  is a side view of the communication device of  FIG. 2   a.    FIG. 2   c  is a rear view of the communication device of  FIG. 2   a.    
      The device  10  is also a pocket sized or smaller and which can be held or worn on a belt as a pendant kept on a key ring or in a handbag. The housing  11  of the device  10  may be rectangular with radiused corners and including with a shackle  12  for connection to a belt, pendant, key ring etc. It will be appreciated that device  10  according to the invention may be manufactured in a variety of non limiting shapes  
      The device  10  includes housing  11  which may be made of soft rubber, a memory storage, a simple controller and preferably a one time use or rechargeable button cell battery. The device is operated by user interaction with LCD display  13 . An ON/OFF switch  5  which may also be incorporated in the screen operation, is used to switch the device  1  off when not in use to conserve the battery life. Device  10  includes LCD display  13 , a light and an IR port  14  for sending and receiving the signals of the text message information. The device also includes an interconnect port to interconnect the device  10  by means of a wire to a standard PC or like device.  
       FIG. 2   d  is a cross section view taken through X-X of  FIG. 2   c  with screen disposed horizontally.  FIG. 2   d  is a cross section view taken through X-X of  FIG. 2   c  with screen disposed in response to user actuation.  
      According to the embodiment shown in  FIGS. 2   d  and  2   e,  screen  13  is supported in cradle  14  having an intermediate underside support which enables cradle and hence screen  13  to rock about pivot assembly  15 . Pivot assembly  15  comprise a male protrusion  16  adapted for pivoting engagement within female recess  17 . As screen rocks in response to pressure applied by a finger  18  of a user, this mechanical action is converted into rotation by cradle  14  which then engages button  19 . Likewise when cradle  14  is rotated in the opposite direction by pressure applied at an opposite end of screen  13 , this causes cradle to engage button  20 . The device may be programmed so that a predetermined number of clicks will cause a predetermined function to occur. The screen effectively rocks and simulates a toggle or rocker switch. Actuation of buttons  19  and  20  may be effected by alternative means to that shown.  
      According to one embodiment, a user interface is effected by a series or sequence of Morse code like navigation steps which may employ North, South, East, West (Compass point) navigation. The navigation may be achieved by a series of clicks on the LCD display  4  which enables the user to press the screen at predetermined locations to move through devices features. Also, navigation regimes may be either factory or user pre programmed into the device or altered via the screen input. The user can define via the PC software the “response to predetermined inputs” which provides the user wide variety of characterizing features so the device suits the users individual requirements. The User may program a security entry click sequence via compass point navigation which unlocks the device to user needed to navigate past an initial welcome screen. User can also program special navigation sequences required for selecting personal or business or other recorded data ready to send to another like device or for downloading to a compatible storage device such as a computer, or to a kiosk network with vending machines ore like peripherals capable of electronic transmission. The device may also be programmed with a sequence for receiving data. The direct screen manipulation may simulate a rocker or toggle switch which would otherwise be used as an alternative to touch-screen navigations. Thus predetermined locations on the screen provide according to one example notional compass points which assist the user in identifying precisely where to interact with the screen. The compass points provide a convenient signpost for the user interaction but it will be appreciated by persons skilled in the art that locations of the screen “switches” may be altered. Due to the combined screen display and screen navigation a suitable reduction in size of the device can be achieved which itself opens new possibilities for applications of the device. For example the device may be employed as a Luggage Tag which attached to a persons luggage as an electronic ID while travelling, as an identity tag for students back packs.  
      User ID data can be displayed via Welcome screen without needing ability (password sequence) to unlock device. The device also functions as a Personal ID or emergency tag in various forms such as a key ring. A person may contact the owner in the event that the device is lost. The device may be programmed for ease of accessibility when used as an aid device or emergency data display device so it may be readily accessed by a by-stander should the owner/bearer be injured or suffer from a medical condition or be lost ( in the case of seniors with memory difficulties or a child). Emergency medical or contact details may be displayed via a Welcome screen without needing ability (password sequence) to unlock device. The device may also be employed in a communications network where the user may communicate with other users via a kiosk type network. According to one embodiment the kiosk may comprise a potentially unlimited number of readily accessible compatible machines which the device can communicate with to download or upload data. When the device is used in conjunction with a supporting communications network, users may allow the device to communicate with another device such as a vending machine or indeed any machine capable of electronic/satellite/radio wave/digital communications which is readily accessible. The vending machine will be networked and will be readily publicly accessible in much the same way as public phones. A user can download messages or other data onto the device at distributed vending machines networked to the internet.  
      Communication may be made by holding a pair of devices  10  so that the IR ports  16  face each other and are close enough to communicate with each other. The users then activate the send function and the data is transferred by the IR signal. The device may be used to exchange details when users meet other users in social or business situations. As an example the device may be used to exchange business cards. Stored messages can be deleted or downloaded to a PC using the PC link. The device  10  can also be pre programmed to display graphic/advertising messages and can be given away as a promotional item or can be sold from a programming/dispensing station within stores, clubs, pubs, shopping malls, etc.  
      It can be seen that device  10  can be used to exchange personal information or preset messages with people one meets anywhere, anytime as long as those persons have a compatible device.  
      There are a number of advantages which derive from use of the device described herein which include the ability to; 
          a) store and display user contact, personal or emergency details;     b) exchange of electronic IDs, messages etc via wire or Infrared;     c) send and receive contact details between other infrared devices;     d) exchange simple messages.        

      The invention will now be described with reference to screens which display access and navigations regimes according to a preferred embodiment.  
      Each screen display shown in the figures referred to below includes at least one operating button shown for illustrative purposes, but it will be appreciated that these can be taken as illustrative of screen locations.  
       FIG. 3  shows the device with blank screen and screen lock and unlock facility. The user may block access to the device or may unlock the screen for access to welcome screen display indicia for ID and emergencies.  
       FIG. 4   a - c  show steps in owner security entry according to one embodiment.  FIG. 3   a  shows a screen including a typical identity and emergency data display which is shown without the need for the users security access code. An owner then inputs a security code via a combination of clicks such as 1 East, 2 North, 2 South, 1 West. This is an example of potentially hundreds of available click combinations which may be factory or user programmed into the device for user access and/or navigation.  FIG. 3   b  is a welcome display screen which appears after the security code has been accepted. The main menu may be presented after the Welcome screen is displayed for three seconds or similar time or by the user clicking the East button.  
       FIG. 5   a - c  show steps for owner to send preset IDs according to one embodiment.  FIG. 5   a  shows a display screen a menu allowing a choice of contacts, send or receive options similar to  FIG. 4   c.  Send may be selected by scrolling to that item in the menu and then pressing east button which results in screen display  5   b  which provides user choices of sending personal ID, business ID or send other. A south button allows scrolling through the available menu.  FIG. 5   c  shows the use of the north button which in the case of the example shown sends business ID which may be phone, fax and Email details  
       FIG. 6   a - d  show steps for owner to send messages according to one embodiment.  FIG. 6   a  shows a display screen a menu allowing a choice of contacts, send or receive options similar to  FIG. 5   a.  To send other non-ID items the user will scroll to that item using the south and north navigation buttons and then click the east button to select their choice. Further choices are available as shown in display  6   b  which provides user choices of sending personal ID, business ID or send other. In the display of  FIG. 6   b  “send other” has been selected. Right clicking on the select other button causes presentation of screen  6   c.  A south button allows scrolling through the available menu ‘send other contact”. A select button allows a user to choose send message.  FIG. 6   d  includes a north send button which in the case of the example shown sends a short text message.  
      Referring to  FIGS. 7   a - d  there is shown an example quick click navigation regime which allows a user to activate pre-chosen options for sending and receiving IDs.  FIG. 7   a  displays a welcome screen available once the security code of the user is accepted. The device may be set so that one or two clicks north for instance will enable a quick view and sending of a user ID. In another embodiment a single south click will allow the device to receive an ID or message from a compatible device. The user may program the device for a particular click regime (eg 1 click, 2 clicks, 3 clicks etc) which navigates to an end screen directly or via intermediate screens. This allows speedy navigation through a predetermined path. These are further shown in screenshots D.  
       FIGS. 8   a - c  show three displays for a contact look up. The main menu is accessed according to the regime described with reference to  FIGS. 4   a - c,  where  FIG. 4   b  is a welcome display screen which appears after the security code has been accepted and  4   c  is a main menu screen. A contact selection is made and a list of contacts are displayed which can be scrolled via north and south navigation buttons, as in  FIG. 8   b.  A particular contact is selected with an east click whereupon the contact is displayed as shown in  FIG. 8   c.    
       FIGS. 9   a - c  show three displays for receiving an ID. The main menu is accessed according to the regime described with reference to  FIGS. 4   a - c,  where  FIG. 4   b  is a welcome display screen which appears after the security code has been accepted and  4   c  is a main menu screen as for  FIG. 9   a.  A selection of receive ID is made by the user which initializes a “ready to receive screen” as in  FIG. 9   b  while waiting to receive ID. Screen  9   c  displays a received ID. The user may navigate by west click from here back to the main menu of  FIG. 9   a.    
      Device Software  
      Screen shots A-G listed below show possible user and security set up options for effective set up operation for the device via enabling software to be used on a PC or PDA.  
      A Pass word  
      B Security code/s input  
      C Welcome Screen  
      D Quick Clicks  
      E Records Screen  
      F Synchronize with compatible Device.  
      G Messages data base  
      The hand held device includes its own enabling software and additional software for synchronization with a compatible device such as but not limited to a palm pilot or PC. The device may also be synchronized with proprietary software such as but not limited to a Microsoft Outlook program. Personal user software includes a number of functions for both set up and user operation. Set up options include password, security and synchronization.  
      A typical password set up option will be related to a compass point code set up. The user chooses their preferred security sequence which can be a combination of one or more east, west, south and north clicks in any order. In the screenshot B the security code becomes, 1 click east, 1 click north and 1 click south in that order.  
      User options also include the ability to customize the welcome screen, “quick clicks” described above, and manage records for personal and business data and messages. The user may select from a variety of data fields which include for example first and last names, addresses city, state, post code and Email. Records held of other users may be loaded from a PC via a records data base directly into the device. These data fields may be loaded from another compatible data base such as from a PC although this requires synchronization by the user (see screen F). The device also allows on the LCD display system icons, images and/or text. The text may be transmitted along with icons.  
      The software includes a password field, which will in a typical case require insertion of a user name and password. This will normally constitute the primary barrier to unauthorized access.  
      A welcome screen may be set up by nominating a welcome screen option in the enabling software. According to one embodiment this may be enabled by entry into fields such as name, address and Email. Alternatively this user ID data may be inputted in a free form format which is not field dependent. The welcome screen may also have included a message, entered in a message field. The personalization software also includes a set up option to establish the aforesaid quick clicks. A predetermined click option may be set for the user&#39;s business or personal ID fields so that when a user requires a personal or business ID to be sent this may be effected by a predetermined click sequence. Thus the direct navigations or shortcuts may be effected by a single or double click for instance without the need to move through otherwise available screen options.  
      Finally, the user may down load standard personal text messages from compatible devices such as a PC. These may be loaded into the device individually or collectively from the parent PC or other device.  
      According to another embodiment, the device incorporates GPS functionality to enable the device to be located and tracked which may be used in combination with the device functions.  
      The foregoing describes only some embodiments of the present invention, and it will be recognized by persons skilled in the art that numerous variations and modifications may be made to the invention broadly described herein without departing from the overall spirit and scope of the invention.
