User Interface Using Java - Case Study Example

Task 3 User Stories User Story User Story ID Based on Persona ID Related to Context ID Related to Activity ID 5 User Story Mr. Brown is an owner of a medium sized company and a father of 4 children. He loves his family a lot and takes every family event very seriously. But with the recent expansion of his company and increase in workload, he now finds it really difficult to remember important family events, like, parent-teacher meetings, picking up the kids from the school, birthdays, doctor checkups, family gatherings, and etc. “It would be really good if I would have something that I could use to schedule important events so that I don’t forget them accidently, and reminds me automatically about the events before their due time. It should allow me to schedule recurring events so that I don’t need to schedule the same event again and again. It should work with major public holidays, like, Christmas, Easter, Independence Day, Labor Day, Mother’s Day, Father’s Day, and etc. I should also be able to schedule events that span two consecutive calendar years.” User Story User Story ID 2 Based on Persona ID 1 Related to Context ID 3 Related to Activity ID 4 User Story Donna loves music. She hears music on her MP3 Player almost all the time when she is in her room. But she does not want to be limited to her room to listen her favorite music. “It would be so fun to enjoy the music no matter if I would be cooking in the kitchen or doing exercise in the gym room, or reading novel in the study room. I would be really happy to use something that could allow me to interact with my MP3 player to play and listen to my favorite music from anywhere in the home. It should provide with me complete navigation capability so that I can select and play my favorite songs. The great thing would be if it could allow me to store my favorite music to any external storage device, like, USB, mobile’s memory, external hard drive, and etc. It should also allow me to control my speakers installed at different locations in the house to adjust their sound volume, as well as MP3 player to stop, play, pause, forward or rewind the music.” User Story User Story ID 3 Based on Persona ID 1 Related to Context ID 1 Related to Activity ID 16, 20 User Story Andy lives with his mother on 1st floor in a 2-storey building, and his mother has rented the ground floor to some other family for the sake of additional income. There are two separate entrances at the ground floor – one for each family. So every time when someone rings the bell at their door, Andy has to go all the way down to the ground floor just to see who’s on the door. “I hate answering to the door, but can’t avoid it as I am the only child on this floor. It’s so awkward to especially go all the way down to the ground floor just to know who is on the door. I wish there would be something that could save me from this trouble. It would not only show the video of the person on the door, but also allow me to talk with that person. Finally, I would like to lock/unlock the door.” Task 2: 3 Conceptual Scenarios Conceptual Scenario Conceptual Scenario ID 1 Based on User Story ID 1 Conceptual Scenario A user will be able to schedule important events in her tablet to receive reminder alerts. A user will also be able to see her existing scheduled events, and should be able to re-schedule or remove them as well. The tablet will provide option for user to mark the event as recurring. Notes: Conceptual Scenario Conceptual Scenario ID 2 Based on User Story ID 2 Conceptual Scenario A user will be able to control her MP3 player as well as speakers (fixed at different locations in the premises) with the tablet from anywhere in her house to play and listen to her favorite music. The tablet will provide options for user to adjust sound of the speakers, and play/pause/stop/forward/rewind the audio. Notes: A user may use multiple functions at a time – for e.g. storing the MP3 music to the external storage device while listening to the same music; therefore, the tablet must be capable to support multiple functions running simultaneously. Conceptual Scenario Conceptual Scenario ID 3 Based on User Story ID 3 Conceptual Scenario A user will be able to answer and open the door with the tablet without the need to physically go at the door. A user will able to verify the person by seeing the video in the tablet screen, as well as talk to the person through the tablet if required. The tablet will provide options to lock or unlock the door. Notes: A user may use multiple functions at a time – for e.g. talking to the person at the door while seeing him in the video; therefore, the tablet must be capable to support multiple functions running in parallel.
