Our Process

Domain Requirement: Source exerpt – A1: As people get older, they tend to experience difficulties with hearing, speaking, vision and memory loss, and muscle weakness. – A3 : go beyond the current realm of AAC to identify all the physical and mental disorders – A6 : expands from the initial definition of AAC which is to deal with speech disorder, and take consideration the speech, hearing, memory and/or vision impairment up to varying degrees. – A8 : In the application domain, the communication typically consists of: An elderly with speech, hearing, vision and/or memory loss.

Domain Requirement: Issue Issue : No clear definition of type of “disabilities” to tackle Options How to select disabilities to tackle – O1. base on project deadlines – O2. base on technical feasibility – O3. base on the similarity of disorders. – O4. base on the most frequent disabilities the elderly population suffers from. Vision Hearing Speech Muscular Memory

Domain Requirement DR1 The system will be used by people that suffer from communication disabilities who have been alphabetized. The disabilities that the system addresses are defined below: hearing disabilities speech disabilities memory disabilities vision disabilities

FR Source excerpt from A19: “Just like the elderly user, the system should be easily usable by the assistive person, e.g. by providing a good search interface through which that person need not know the entire system and can bring up any part by just visiting the search page. “ Issue 9: What defines a “good” search interface? Options O1. “Google-like” search O2. Search with auto-completion O3. Search by complete words O4. Search by incomplete words O5. Search stored sentences O6. Search using voice recognition based on Google API

FR Choice and Rationale O3 O5 O6

FR: I  O FR 2: The system shall provide a search interface to allow users to retrieve: Favorite sentences Built-in common greetings Recently generated sentences Individual vocabulary items FR 2.1 The search feature shall be reachable from anywhere in the system. FR 2.2 The search input shall be converted from the recognized voice of the user. FR 2.3 Search results shall be returned in a scrollable list format containing an image and a text description of a sentence or vocabulary item for search result. FR 2.4 When the user clicks on a search result item, the system shall speak the item description out loud. I: a vocal input O: a list of search results showing image and description

NFR Source excerpt : “The system should be quickly understandable (the learning time should be very low) and very easy to use “ Issue I25: The system should be quickly understandable Description: What is meant by understandable ? Understandable is Ambiguous here. Options: O1. Text is easy to read O2. Low learning curve O3. Visual aids should have a minimal specified resolution (e.g., not blurry) O4. The user should be able to learn how to use the application in 2 weeks, using it 3 hours a day. Choice: O1, O2, O3.

Issue with the choices Issue I25.1: Text is easy to read. Description: What functional features shall realize “easy to read”. Options: O1. Choose contrasting colors O2. Choose a large icon size O3. Choose a large text size Choice: O1,O2,O3

Issue with the choices Issue I25.2: Low learning curve. Description: What functional features shall realize “Low learning curve”. Options: O1. One touch help shortcut O2. User manual written in non-technical language O3. Icons with descriptive text O4. Provide technical support O5. Interactive tutorial built-in the application Choice: O1,O2,O3
