Introduction
Purpose
The purpose of this document is to compile all documentation on the SE 4351 Preliminary Project Phase II, or the Senior Reminder System Project. This documentation will include the Requirements Specification containing the functional and nonfunctional requirements for this project, the Program Specification containing the implementation of the project, and the User Manual. Having all of this documentation will outline for the reader the motivations and decisions that shaped the development of this project.Scope
The project is defined by the boundaries of the selection process and our narrowing of the project definition. Project selection was completed by meeting together and each person suggesting an idea. After discussion of the upsides and downsides of the various ideas, our team came to a unified agreement on a reminder system. Review of the project goals, deliverables, tasks to complete, their associated costs and deadlines, further narrowed our project to a precise application idea.Objectives and Success Criteria
The goal of this project is to create an Android App to help elderly people manage events and important tasks like taking their medicine. In order to better define the behavior of this system, we devised a Requirements Specification further clarifying what functionality this system is required to fulfill, such as functionality and constraints. Furthermore, we specified that this system was to be implemented using an SQLite database.Problems
The largest problem in successfully creating an App for the domain of this project is that inherently as age increases, familiarity with the latest technology decreases. Our team will have to create an App that is extremely easy to use, even for users with declining motor skills, eye sight, and memory. The App will have to be easy to access, easy to use, while avoiding letting the user unintentionally modify items.Goals
As a group we have decided that our two main goals are to create an App that is effortless to access and very intuitive to use. If the user can’t remember the exact workings of the app, we want it to be intuitive and natural to use so they are still able to use it. This will be a tremendousgoal because it means that the user only needs to remember they have the App and none of the details of use. Some of our lesser goals are: creating object persistence that supports useful features, giving a caregiver an easy to way to supplement the user’s use of the App, and easy ways to navigate the app like voice search.
Definitions
SR Senior Reminder
The formal title of our phase 1 project abbreviated for ease of writing and reading.Android
Mobile Operating System developed by Google Inc.ObjectOriented
A methodology that enables a system to be modeled as a set of objects that can be controlled and manipulated in a modular manner.App
A program or piece of software designed and written to fulfill a particular purpose of the user.Category
A category is a descriptor containing the multidimensional vocabulary items having a similar meaning, relation and/or purpose.Reminder
A small collection of data about an important event that includes a task and time.Disjoint Category
A disjoint category is one that does not have its items overlap with any other category.Overlapping Category
An overlapping category is one that has one or more of its items overlap with items in other categories. Categories can be either activitybased or itembased at the root level e.g. items as in ‘Food’, ‘Drink’, ‘People’ etc. and activities like ‘ I want to eat’, ‘I want to go’ etc.Positioning
Business Opportunity
Remembering important tasks becomes a more challenging goal as people get older. Elderly people often develop health problems or symptoms such as Alzheimer's and loss of the senses. A system that can be simple and intuitive yet dynamically manage tasks is of great aid to those who have a hard time remembering things. In addition, if the interface is simple and has large easy to identify buttons, then the system will not be an additional burden on the elderly users. The users will be spread out amongst the affected elderly, as well as their loved ones. The system will provide task tracking functions and a simple ease of use focused interface to achieve user satisfaction.Problem Statement
The problem of loss of memory, senses and ability to remember tasks affects elderly people with moderate Alzheimer’s disease the impact of which is lower quality of life, loss of independence, and increased burden on the elderly and their caretakers a successful solution would be a cheap cost effective system that allows users to track and complete tasks without difficulty. The product should support a primary mobile user to view, adjust, and supplement the user's task list. The product should have reminders to create a simple way for information to be displayed across multiple views (mobile through SQLite).Product Position Statement
For elderly people with moderate Alzheimer’s disease Who suffer from loss of memory, senses and ability to remember tasks Senior Reminder System (SRS) Is a mobile software application That provides the ability of reminder persistence and management in a simple interfaceUnlike current mobile applications that do not focus on user interface for elderly users Our Product utilizes a simplistic and easy to use interface for creating, retrieving, updating, and deleting reminders. The system supports authorized access to reminders through SQLite.

Product Overview
Product Perspective
Summary of Capabilities
Customer Benefit Supporting Features Reminders will be shown in a simple tile interface with minimal buttons ● User can associate an image or graphic with a individual tile. ● User can edit the color of an individual tile. ● Button usage will be minimal and use icons in place of words. System will create, retrieve, update, and delete reminders ● System supports regular text keyboard entry or voice to text entry of reminders ● Time selection is done using Google’s clock wheel to avoid clumsy manual entries of time. ● All reminders will be persisted using SQLite and will have an interface to create, retrieve, update and delete reminders. ● To avoid accidental changes, all destructive modifications will require a second confirmation action. In the event of an a missed reminder, an emergency contact will be notified ● System will alert caretaker and authorities in the event of a missed reminder or critical importance ● System will use SMS to make sure that the alert can be received by most devices. System will notify the mobile user of approaching reminders ● Reminders will have a time associated with them and the system will push a notification out to the user to remind them of an impending task so that they have time to prepare to complete the task if they have forgotten. ● Reminders will play an alarm when the task reaches notification time, this will alert the user to complete the task.● A emergency button will be available for contacting 911 services.

Security
● Security should be wellimplemented outside the view of the user. Security will use Googlebacked authentication, access control, data integrity, and data privacy. ● Authentication of the user is done by the android system. If the user is not logged in on their Android phone, authentication will fail. ● Elderly users can view and change the reminders. ● Transmissions will not be encrypted by the application, any encryption will be native to the Android and SQLite API.Usability
● Easy to use ● UserFriendly interface with large graphic tiles and text ● Request for an ambulance, police, or fire truck needs to be a tile to be pushed or caretaker needs to be alerted of potential emergencyResponsiveness
● System responds quickly to user requests or changes in the environment ● System responds within 0.5 seconds on average to local user requests and changes in the environment. ● System responds within 0.5 seconds on average to remote user requests and changes in the environment.Capacity
● There is no maximum for the number of reminders ○ Maximum reminder capacity is limited by the SQLite database capacity. ○ View of reminders is limited by the frame of time being viewed. ● Maximum number of active notifications is limited by Android API ● Maximum number of active alerts/alarms is limited to one (1). ● Maximum number of emergency contacts is limited to one (1).Appendix
