3. DECISION AND RATIONALE: INTEGRATED MODEL (IMPROVED UNDERSTANDING)
3.1 WORLDThe words World, Domain and Environment all refer to things in the environment (application domain) that are true regardless of the proposed system. This section includes the improved understanding of the domain requirements. It breaks down the problems, goals, and functional and nonfunctional aspects of the domain requirements. 3.1.1 Problems: Hearing: 1. Most of the elders have various hearing disorders such as partial deafness. They have difficulty in making out what’s being spoken to them. This affects their day – to – day activities. 2. Most of them suffering from hearing loss do not evince interest in wearing hearing aids. 3. People with severe hearing loss when conversing with others would find it difficult to understand unless the speech is accompanied by some relevant hand gestures or something that at least vaguely resembles the sign language. 4. People with hearing loss are a hazard to both themselves and others, they might not respond to the sounding horns on road that may lead to accidents. 5. They might not respond to fire alarms, emergency sirens that would once again lead to personal hazard. Speech Clarity: 1. Elderly sometimes have problems in clearly conveying themselves to others. 2. This acts a barrier when they interact with others as well as their family members. 3. Sometimes they have to write it down, if they have to convey it to others. 4. They cannot shout out loud during an emergency, or speak properly on a phone to the emergency services. Vision 1. Due to the old age, they sometimes experience loss in vision. This would seriously cripple their day – to – day abilities. 2. They would have trouble in reading things and making them out, or finding misplaced things. 3. They would not make out danger signs and may be a potential hazard on road, and off road. Memory Loss 1. It would be difficult to remembering things as people age. Hence they need some kind of an aid to remember things. 2. They forget to take their medicines on time. 3. They miss out on certain important schedules. 4. They would not be fit to manage their finances as it would require a good memory to keep the complex password in mind. Everyday Living 1. The elderly may not be able to drive themselves to the doctor. They might not be able to cook for themselves or tend to themselves. 2. To keep themselves updated on the news would be difficult for them. 3. They would definitely need a scheduler or task manager for their daily routine. 3.1.2 Goals G1: Assist someone with hearing loss in communicating with the other person G2: Help someone with hearing loss in understanding the other person G3: Help someone with difficulty in expressing his or her ideas through speech G4: Help someone in emergency to be immediately assisted. G5: Help someone with memory loss to remember the location of the everyday usage things. G6: Help someone with memory loss to remember relatives and friends. G7: Help an elderly person in reminding them to take their medicine on time. G8: Allow an elderly person call for help from family, an assistant or the authorities G9: Help an elderly person to track his metabolism. G10: Help an elderly person choose his diet. G11: Keep an elderly person up to date on their finances. 3.1.3 Improved Functional Understanding of the Domain: World with Backward Tracebility WF1: The user should have an Android phone ---- DR0 WF2: The user should know how to use the basic features of the Android phone ---- DR1 WF3: The phone must have HOPE services running on it. ---- DR2 WF4: Users with loss in memory and vision must be sure to keep the mobile always with them----DR0 WF5: Old people suffering from hearing problem will need a speech to text converter---- DR4 WF6: There should always be a person within 10 meters of the old person to help him. ---- DR24 WF7: The elderly who have trouble hearing will need a speech-to-text application to hear well----DR4 WF8: The images of the frequently used words are stored in the phone’s memory---- DR18 WF9: The elderly who have trouble remembering will need an application to remember the location of everyday used things. ---- DR15 WF10: The user needs to keep the phone on their person to be able to use the system. ---- DR13 WF11: Old people suffering from speech disorders will need to be able to use images or icons to ask for help when in need. ---- DR14 and DR10 WF12: People with extremely unclear vision will need things read aloud to them instead of being able to read text. ---- DR17 WF13: When two people have problems in oral communication they should use pictograms for communication. ---- DR14 and DR10 WF14: Old people having speech clarity problems would benefit from a system that provides a user interface to type the message they want to express. ---- DR9 WF15: Old people with memory problems will need applications to remind them of the locations of the things used every day. ---- DR15 and DR16 WF16: Old people with memory problems will need applications to remind them of medicines to be consumed every day. ---- DR19 WF17: A text to speech application would help people who have trouble speaking clearly. ---- DR5 3.1.4 Improved Non Functional Understanding of the Domain: World with Backward Tracebility WNF1: The elderly expect their phone to respond to commands within 2 seconds. ---- NFR1, NFR7, NFR12 WNF2: It is helpful for an elderly person to alert his care taker to immediately attend to him with just one-click ---- NFR11, NFR19, NFR20 WNF3: Elderly people prefer to use applications that are user friendly.---NFR3,NFR10, NFR21,NFR23 3.2 Requirement Specification 3.2.1 Functional RS – Improved understanding of Software System Requirements: FRsThe objective of HOPE is to provide a platform for helping the elderly, the disabled having unclear speech, hearing loss, weak vision and/or memory loss, in day – to day communications. This platform helps the elderly, and this section deals with the domain: Functional requirements in Requirement Specification. FR-01: Elderly people use HOPE to communicate effectively with other people and perform their day to day activities without a frustrating level of difficulty FR-02: HOPE shall assist users in the all activities FR-03: The speech to text converter is used to interpret every word spoken by the elderly person. FR-04: The MyPage application will allow the user to store all personal information about the user FR-05: Elderly people with memory problems will use the Pill-Tracker to remind them to consume medicines and also update medicine stock with the help of the care taker. FR-06: An elderly person with unclear speech shall use text to speech converter to express messages to people within 5 meters. FR-07: The care taker of the elderly person stores information of the location of the everyday things used at home so that it is easily accessible. FR-08: The DietManager feature is used by all users to input the health condition rangeand obtain a list of food items to be consumed and to be avoided. FR-09:The Walk-O-Meterapplication is used by the elderly person while walking to calculate the approximate calories burnt. A timer started at the beginning of a walking session computes the calories based on an average walking speed determined for elderly people. FR-10: The applications for contacts with pictures and also elements of Pic-talk not only display the images but also read out the content aloud. FR-11: The system will help the usersto store personal and secured information like Banck Account details, SSN, etc with a password protection feature in the MyPage feature of the HOPE application. FR-12: The call for help feature allows the user to select from the emergency services, family and their assistant and puts them in touch within 10 seconds with just one-click reach FR-13: The templates used for text messages and PicTalk are self-explanatory and help the elderly person frame his message easily and convey quickly. FR-14: The Pic-Talk which is used as a message board creates a message which can be displayed as well as sent as a text message to others. FR-15: The medication assistant reminds the user to take their medicines by displaying the name or image of the medicine at the time prescribed by the doctor. 3.2.2 Non-functional RS -Improved understanding of Software System Requirements: NFRs
