##II. Synthesis ###1. Requirements Definition ###a. Context Scenarios

#####-Our persona is Susan Wong, a professional lawyer, whose goals are to understand her autistic child. #####-Here is Susan’s context scenario: ######1. While getting ready in the morning, Susan makes sure her child, Abby is wearing the E&F wristband before she is going to work. ######2. When she is dealing with her client, her phone rings. She checks her phone and she received a notification from the app. Normally while she is in an appointment, she will mute her phone, but when Abby is experiencing emotional turmoil, the app will automatically send her a notification. ######3. The app suggests fews ways for Susan to answer the notification. The app is having the calling button that allow Susan to call the nanny of Abby or her husband. The app is also having the camera button and cancel button. ######4. Susan first chooses to call the nanny but the nanny did not answer her phone call. Then, Susan calls her husband but she gets a voicemail; he must out of service range. ######5. Susan failed to contact the nanny and her husband. So, she clicks on the camera button from the app. This camera button is allowing Susan to activate the camera of Abby's wristband and she can see what Abby is doing now. When the camera is activated, she sees that Abby is drawing in her room. After she made sure that Abby is safe, she closes the app and continues her meeting with her client. ######6. Five minutes later, the phones sounds a brief tone. Susan receive an instant message from the nanny:" Don't worry, Abby is scared by a rat just now. I had killed the rat and Abby has now calmed down."
