1. Introduction




1.1 Purpose


The purpose of this document is to collect, analyze the features and define the high level needs of the Helping Old People Easily System (HOPE). This document is concerned with the stakeholder’s needs, the users and why those needs exist. The product overview and the high level features are also covered in the Vision document. Any further details about the HOPE System are listed in Use-Case and supplementary specifications.

1.2 Scope


This Vision Document applies to the HOPE System which will be developed by the Project Total Recall team. The HOPE is a software application which runs on a mobile device. The HOPE app aims to be a help to any person suffering of category 3 Dementia, by maintaining lists of people, locations and things. These lists can be expanded, updated or deleted the application’s owner.

1.4 Definitions and Glossary

2. Positioning




2.1 Business Opportunity


Many applications like Evernote and Pocket are designed to help users ‘bookmark’ and take notes to record things a user believes to be valuable. But neither of the applications are actually designed to make recalling items simple. This project caters to an underrepresented audience in the Android market. An audience that struggles with memory loss which inhibits their ability to communicate effectively.

2.2 Problem Statement


The Problem

of communication difficulties caused by Stage 3 dementia (memory loss)

Affects

many individuals regardless of age, race, or gender.

The impact of which is

serious communication issues that constrain personal relationships, everyday activities, working ability, or any other activity that requires communication.

A successful solution would be

an application that eliminates communication difficulties by providing a repository of objects that the user would want to or like to remember.



2.2.1 P-I-G Diagram




2.3 Product Position Statement





For

individuals with communication difficulties caused by Stage 3 dementia (memory loss)

Who

feel the need to solve their communication issues by mitigating their memory loss problems.

Total Recall

provides the efficient access to an object repository that can be filled with objects and information about those objects

That

provides the user with a solution for communication issues brought on by lack of ability to remember objects, or details about those objects.

Unlike

current products that are tailored for specific use case scenarios and are thus inflexible and hard to use in any “non-approved” usage,

Our Product

is an object repository platform that is open-ended and flexible as a solution for communication problems brought on by memory loss.

3. Stakeholder and User Descriptions




3.1 Market Demographics


The target market segment includes smart phone users that have mild dementia or memory loss living in cities that are more urban and modern with internet access to their phones. The users are anticipated to be customers that use their phones for personal use that can help guide them through their everyday lives. Most smart phones range from $500 - $800 without a contract and around $100-$300 with a contract. With access to this application from the Google Play Store, many users can utilize our services through their own phone without having to purchase anything else in addition.

4. Product Overview




4.1 Product Perspective Overview


This application is almost entirely self-contained. Everything takes place within the user’s Android device. This is the internal architecture of the system:

The application layer encompasses the vast majority of the system and communicates with several external services through APIs. The application layer interfaces with the Android system’s camera and gallery services in order to load images and icons into the system. Most importantly, the application layer interacts with the external DBMS through the DBMS interface to persist all objects if the user elects to save them.




The system shall enable the user to create, edit, delete, and view specific types of objects. System supported types of objects are Person, Place, or Thing objects. The user can designate these as Emergency objects for the purposes of direct access if desired. The system persists all objects in the external database if the user saves the object.


Each Person, Place, or Thing object has specific attributes that enable the user to store important information about that object. The system adds the additional capability of allowing the user to define meaning and substance to each object through the addition of an image attachment and an icon. The user can also be as descriptive as they desire about the object by detailing specific textual description in the Note attribute.


4.2 Summary of Capabilities





Customer Benefit

Supporting Features

Prioritized emergency contacts

Robust search capabilities

All attribute of every object are searchable to provide accurate searching

4.2.1 S-I-G Diagram




4.3 Assumptions and Dependencies


The software will operate on an Android device with the following minimum hardware specifications:

  • Software version 4.4.2, API 19

  • 2048 MB RAM

  • 200 MB internal storage

The database will be stored on the Android device. This ensures that users will not need a consistent 4G or WiFi connection in order to use the application.


4.4 Cost and Pricing


The system will be distributed through the Android store for free. This is done for two main reasons. First, the Android store requires a licensing process in order to monetize an application, which could create a period of time in which the product is ready but cannot be released. Second, a free application is more likely to be selected for usage than a new one that costs money. By not charging anything, we can increase our early user base.

4.5 Licensing and Installation


The Android store will need to approve of the application before it can be distributed. The application needs a fully completed application package (APK). The APK requires developers to modify the existing code into a signed release version of the application. The system will need API release keys for the onboard camera application to ensure legal connectivity. Promotional materials must be prepared, such as screenshots and working graphics. The application will then be uploaded to the App Marketplace for release. The system will be directly installed on the Android devices through the App Marketplace. It will be downloaded through the user’s internet connection and then installed.

7. Constraints



For this system to function correctly we shall assume that the user suffers from Stage 3 (“Mild”) Dementia or less which will allow said user to be the only person responsible for operating the application. The system that the application will run on shall be an Android device with software version 4.4.2 or higher and contain the necessary hardware components to satisfy the functional needs of said application such as a camera.
