Title: Smartphone accessory for visually impaired or elderly users

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The field of the invention relates to an accessory for a smartphone, or other type of portable electronic device, and which provides features to assist a visually impaired or elderly end-user. The system may also appeal to general users with good vision who prefer a simple to use device, or for whom the features offered by the accessory are especially useful.

The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever. 
     2. Description of the Prior Art 
     Portable electronic devices, such as smartphones and tablets, are in widespread use, but the dominant, typical form factor, a sheet of touch-screen glass in a thin casing, can be challenging for blind or low-vision users to operate confidently and with assurance. In addition, existing graphical user interfaces for the most popular smartphones and tablets are not fully adapted for visually impaired or elderly end-users; they may include some features, such as text magnification, but that is far from a UI that is fully and completely adapted for the needs of the visually impaired or elderly. Nevertheless, smartphones and tablets designed for mainstream use are also popular with blind and low-vision end-users because of the high-quality of manufacturing and materials, leading to an engaging tactile experience, and the large number of third party apps available. 
     There are some smartphones that are specifically designed for the elderly. These can have a UI that is highly simplified. But because these smartphones are designed for a relatively small customer group, and are not designed for the mass-market mainstream, they tend not to include the latest hardware and are hence quite low specification devices that are several generations behind the latest mass-market devices. 
     There is great scope for improving the user experience for visually impaired or elderly users who want a more simplified smartphone or tablet experience, but based on the latest generation, high specification smartphone or tablet. 
     The present invention addresses the above vulnerabilities and also other problems not described above. 
     SUMMARY OF THE INVENTION 
     One aspect of the invention is an accessory system for a smartphone or tablet or other wireless device, the system comprising:
         (a) a case that slides or clips or otherwise attaches to the device, the case enabling one or more features or functions of the device to be enhanced, altered, replaced or varied to include features or functions of specific utility for visually impaired or elderly users; and   (b) software that when installed on the device automatically enhances, alters, replaces or varies pre-installed software on the device to include features or functions of specific utility for visually impaired or elderly users.       

     The case may come in two parts, namely (a) a base that the user slides or clips or otherwise attaches onto the device, and (b) an accessory or extension module that the user also slides or clips or otherwise attaches onto the device and that provide features or functions that are specific to the needs of the visually impaired or elderly. Different accessory or extension modules can be slid or clipped or otherwise attached on to the device to provide the different functions or features. 
     The invention is implemented in a system called the Zone V system. The Zone V system is in essence an accessory case that slides onto a fully featured, latest generation smartphone or tablet, combined with software that can be readily downloaded and installed onto the smartphone that alters the entire UI of that smartphone in a way that is simplified and optimised for visually impaired or elderly users. The case itself comes in two parts—a base that the user slides or clips on to the smartphone, and a removable accessory or extension module that also slides or clips on to the smartphone and that provide features that are specific to the needs of the visually impaired or elderly. Different accessory modules can be slid or clipped on to the smartphone (such as a large grab handle; or an enhanced speaker, or physical buttons programmed to call specific people). The software then provides not only a simplified environment, but also then enables control of the features or functions provided by the specific extension unit that has been fitted. 
     This approach enables the visually impaired or elderly user to have all the benefits of a latest generation smartphone, (ie the most current hardware specifications, such as display screen, operating system, wireless connectivity), and which is readily available through all conventional distribution channels, and yet to have it fully customisable at low cost for their specific needs as a visually impaired or elderly user.

FIG. 17  shows diagrams with different views of a USB cable connector. 
       FIG. 18  shows a case for a smartphone comprising an additional lens. As seen in  FIG. 19 , the additional lens can be moved into position over a camera lens integrated into the smartphone. The additional lens is fully integrated with the case. The lens can be placed over the camera lens via a slide or by any other means. The lens may be one of the following: a magnifying lens, a wide-angle lens or any other optical lens. 
     Software Application that is Configured to Work Seamlessly with the Protective Case 
     Another aspect of the invention is a software application that is executable on a portable electronic device such that the device can switch to another and simpler user interface as illustrated in the following figures. The software application is configured to work seamlessly with the protective case described above when the protective case is placed on the portable electronic device. 
     The Zone V project utilizes a user interface (UI) overlay provided in the form of an .apk (Android Application Package File) launcher or any other equivalent launcher. 
     With reference to  FIG. 20 , when the device is first turned on, it first boots into the factory installed graphical user interface. On the home screen, a large widget with a Zone V icon is placed such that, when pressed, the Zone V user interface is launched. The end-user is then presented with the option to ‘Always’ select this launcher. If ‘Always’ is selected, the Zone V software application will then be automatically executed when the device is switched on or unlocked. Once in the Zone V UI, the user may exit into the factory installed launcher through an option in the settings menu. A user may also load a standard 3 rd  party application through the Zone V UI. One key feature of this approach is that a standard Android or equivalent application can be ran directly through the Zone V UI and can exit back into the Zone V UI after exiting the app. 
     Additionally, the first boot up may present users with a series of questions that will determine the configuration mode of the Zone V handset. The first page may then load a menu corresponding to different visual modes, such as, but not limited to: stock android mode, senior mode, visual impairment mode, no sight mode or advanced configuration mode. 
     The Zone V software application is configured to work seamlessly with the protective case described above when the protective case is placed on the portable electronic device. The features available on the protective case such as the function keys may provide different feedback based on the context. Hence for example in no sight mode, the up and down function keys may act as page up/down and in senior mode, they may provide zoom in/out functions. 
     In addition, a visual mode may generate a high contrast black and white image or alternative colours in order to give optimal contrast and clarity. Another visual mode may invert black and white. The different visual modes may also generate different font sizes pre-selected by the end-user for one or more menu items. Generally, the visual modes provide enlarged text in order to make text easier to read for an end-user. Different font sizes for one or more web sites or apps that support dynamic font re-sizing may be available through the visual modes. One configurable setting also provides for the font size to be changed automatically in all the web sites or apps that supports dynamic text sizing. 
     As an example the senior mode takes advantage of the large text and easy to use menu system. The senior mode has the following default settings:
         Selection method: single tap;   Voice feedback: disabled;   Haptic feedback: enabled;   Scrolling: standard list scroll.       

     The visually impaired mode takes advantage of the grid system and audio feedback. The visually impaired mode has the following default settings:
         Selection method: double tap;   Voice feedback: enabled;   Haptic feedback: enabled;   Scrolling: side buttons.       

     The advanced configuration mode has the following configurable settings:
         Voice feedback (TalkBack) on/off;   Volume level: ring tone, notifications &amp; talk back;   Haptic intensity level on/off;   Scrolling method: standard list scroll or side buttons;   Selection method: single or double tap.       

     The default profiles can be adjusted by the end-user in order to customize the end-user experience. The following may be customised:
         Inverted colours—black on white vs. white on black;   Selection method—select single tap or double tap;   Voice feedback—on/off &amp; volume setting;   Haptic feedback—on/off &amp; level of intensity;   Scrolling—Standard android scroll or side buttons;   Changing of font sizes—increase font size across UI.       

     In addition to the graphical interface, integral to the operation of the device is the ability to allow for TalkBack to be enabled throughout the device if the user has chosen to switch this service on. 
       FIG. 21  shows the widget of the software application with a Zone V icon as seen on the factory installed graphical user interface. By clicking on the widget, the software application is executed on the smartphone and the graphical interface is switched to another simplified graphical user interface (Zone V) that displays all text in an enlarged font size and alters the appearance of all menu items to increase legibility. 
       FIGS. 22 and 23  show the home screen of the simplified graphical user interface that is split into zones. The zones may also be colour coded. The home screen shows top-level menu items. Menu items at the top level may include one or more of the following: messages, contacts, phone, settings, calendar, clock, applications, arrange apps, emergency contact, any pre-selected app, email, internet, GPS, video tutorial, exit. 
     The user interface also provides a fixed bottom menu, which displays four icons for easy access of pre-defined items, for example: magnifier, calculator, torch and camera. 
     The top-level menu items displayed on the home screen may be turned on or off. By clicking, tapping or selecting via voice control one of the menu items, further specific functions are accessed. 
     An end-user will be provided with the ability to choose home screen items. Within the settings of the Zone V user interface, the user will have the ability to order items on the home screens, allowing for customisation for easy access to most used applications, including 3 rd  party applications. 
       FIG. 24  shows a screenshot of the graphical user interface when the Magnifier mode is selected which enables a magnified image or text to be shown directly on a smartphone. One visual mode automatically inverts the colour of the image in order to aid readability. Increase magnification (+) or decrease magnification (−) may also be selected. An image mode and a video mode may be available. 
       FIG. 25  shows a screenshot of the graphical user interface when the Calendar mode is selected. The calendar may also feature a list view or a month view. 
     A clock menu item can also be selected. The clock may include an alarm function and may read out the time as well as the alarm. The clock application will also have a reminders function that allows for the creation of reminders for regular (or single) events with notes. 
     A location app can also provide users with details about the locations of interest that are in the vicinity and which may feature: a direction service (with the ability to enter an address and get directions in text or voice format), a compass, nearby points of interest listing nearby locations. 
       FIG. 26  shows a screenshot of the graphical user interface when the Phone mode is selected. 
       FIG. 27  shows a screenshot of the graphical user interface when the Messages mode is selected. 
       FIGS. 28 to 30  show screenshots of the Settings menu split into zones. Settings menu items are arranged into rows, which can be vertically scrollable with a touch swipe up or down to reveal, other menu rows. 
       FIG. 31  shows a screenshot of the visual profiles available through the Settings menu. An example of four profiles is given: standard, light, dark and voice feedback, which have been designed to give optimal contrast and clarity. 
       FIG. 32  shows screenshots with home screens of a number of visual profiles: dark ( 321 ), light ( 322 ), standard ( 323 ) and standard with wallpaper ( 324 ). 
       FIG. 33  shows a screenshot of the keypad. 
       FIG. 34  shows different actions or gestures that may be performed by an end-user to interact with the smartphone, for example:
         tap ( 341 ): tap your devices screen to enter an application, complete an action, activating an on/off switch or entering letters using the key board.   double tap ( 342 ): when the voice feedback profile has been selected, a double tap ( 342 ) may be used to enter an application, complete an action, activate an on/off switch or enter letters using the key board.   swipe ( 343 ): Using your index finger swipe ( 343 ) to the left or right such as when using the gallery,   scroll ( 344 ): When in standard, light or dark mode, place one finger on the screen and move your finger up and down the screen to scroll through a list of information.   scroll ( 345 ): When the voice feedback profile has been selected, place two fingers on the screen and move your fingers in parallel up and down the screen to scroll.   Tap and drag ( 346 ): using your index finger tap and drag the icon in the direction of the arrows such as when answering or rejecting a call.       

     Zone V Downloading, Installation and Registration 
     Secure software downloading to mobile phones from websites often requires the inputting of unique keys to prevent fraud. The process can be complex and is not easily useable by non-technical consumers. The Zone V install process makes downloading, installation and registering significantly simpler for the user. 
     A simplified installation process has been developed in order to significantly simplify the downloading of the Zone V software. It can be used wherever software needs to be installed on a portable electronic device, especially one with wireless connectivity. 
     Key features of the process include, but are not limited to:
         use of an NFC sticker, for example inserted in the user guide, in order to trigger the smartphone to navigate to the download site.   integrated code to show install button once the download is complete;   use of a bar code reader integrated into the registration process to load the security code.       

       FIGS. 35 to 43  illustrate the key steps of a Zone V software downloading installing and registration process on a portable electronic device. 
       FIG. 35  shows a diagram illustrating an electronic portable device that has an NFC chip and that is tapped near or on another NFC sticker, for example placed on an installation guide, in order to launch a selected Internet browser. 
       FIG. 36  shows a screenshot with the selected Internet browser that has been launched after tapping the phone near the NFC sticker, and that is displaying terms and conditions of the Zone V software Licence. 
       FIG. 37  shows a screenshot with the selected Internet browser displaying a checkbox that can be selected in order to agree the terms of the Zone V software licence. Once the box is selected, the download of the Zone V software begins. 
       FIG. 38  shows a screenshot with a pop up that is presented to the end-user once the download of the Zone V software has been completed with the ability to select ‘Package Installer’. 
       FIG. 39  shows a screenshot of the Zone V app displaying terms and conditions after the package install has finished. 
       FIG. 40  shows a screenshot of the Zone V app displaying a registration page. 
       FIG. 41  shows a screenshot of a portable electronic device scanning a barcode that is located on an installation guide, for software code entry. 
       FIG. 42  shows a screenshot of a portable electronic device confirming that the barcode was read. 
       FIG. 43  shows a screenshot displaying the code, corresponding to the previously read barcode, automatically entered onto a registration page of the Zone V app. 
     Remote Service 
     A remote service is also be provided for Zone V user accounts that would give 3 rd  party users the ability to view and/or edit specified data from a Zone V user&#39;s account. Only invited users can have ability to access the data. Hence, strong privacy protection is required. 
     A web portal may be provided as responsive website. The web portal is wrapped to a native Android, iOS or equivalent app such that the portal may be used on desktop, or any iOS or Android device. 
     The remote service or web portal provides access to a remotely control Zone V app for specified users who granted the editing permissions to 3rd party users (for example friends and/or family members) who may then use the remove services to access the device, read, edit or delete data from the device and Zone V user accounts. 
     Different interfaces for different access levels are provided. As an example, an owner, usually a sight impaired person, may need a more visual friendly interface and its interface includes the following features, such as, but not limited to:
         ability to select either black on white or white on back colour scheme;   higher zoom in responsive design—need bigger elements, easier to read and/or navigate through.       

     The interface for a viewer or admin, includes for example:
         the ability to select either black on white or white on back colour scheme;   a regular responsive design.       

     Account initialization: a new remote service account can be created during an end-user&#39;s default sign up to Zone V app. The main user of the Zone V app is the default owner of the account on the remote web-portal. Each user of the Zone V is able to sign in to Zone V app via an email account or any other equivalent means. During the sign up to Zone V process, a user is given an option to create their remote service account and select data that they want to sync with this account. If a user uses this option, they are taken out to the remote service app/web browser where they are requested to register. 
     Additionally a user may be requested to provide access permissions to the Zone V app for their email account for the following data:
         user&#39;s basic details—name, email;   contacts;   calendar events;   images—picasa photos.       

     The owner is therefore requested to authorize the email account access permissions for the Zone V app during their first login to the remote system. 
     An end-user also needs to select what part of data they want to sync with the remote service. Only these data can be shared and available for read and/or write in remote account. These may all be optional, but should be all pre-selected by default, for example:
         Contacts;   Calendar events;   Bookmarks;   Photos;   ICE;   Location;   Device Settings.   Profile Settings.       

     User invitation: an invitation for new users to remote account is sent via web portal. This feature is available to the users with admin or owner permissions only. These users are able to add new users and/or send invites and remove existing users. 
     Different levels of end-user&#39;s access permissions are given, for example: owner, admin and/or viewer. Owner or admin end-users are able to invite new users via app or web-portal. 
     Account permissions select what permissions a user may be granted:
         Admin;   Viewer—the following permissions may be setup:
           Contacts—read/write permission;   Calendar—read/write permission;   Bookmarks—read/write permission;   Photos—read/write permission;   Settings—read/write permission;   Location—read permission only.   
               

     Invitation sent via email is valid for limited period only. Owner and user who sent the invite (if different from the owner) are notified via email about the acceptance/decline of the invite. 
     An API allows the Zone V app to interact with the remote service portal/account. The remote server API has the following features:
         create new user account/remote service access during Zone V user sign up;   send device summary—model &amp; firmware during sign up. This is saved in a remote database under the specific end-user account;   admins—pull list of admins/viewers of the app along with their read/write permissions;   edit admins/viewers.
