There are now a variety of companies marketing "wearable" devices. Examples include the Apple Watch, Fitbit, Garmin, Samsung, Snapchat spectacles, and many others. Some of these devices are starting to enter the medical realm, such as continuous glucose monitors, watches that detect Afib, and even the ability to generate an electrocardiogram on the Apple Series 4 watch. There are other devices with less attention but more direct emphasis on various medical aspects, such as the Air Louisville device that monitors air quality for inhalers, the iTBra designed to help detect breast cancer, the Kardia band for AFIB detection, the Aira device for guiding the blind, and many others. Your assignment is to pick one of these medical devices for which you will be doing an ongoing analysis (over multiple case studies). For this case study, describe the device, who makes it, and provide references (links). In addition, answer the following questions based on your findings:

1. Who are the likely stakeholders for this device and associated support systems? What user roles were likely involved in requirements definition for the device? 2. Assuming you were the lead systems analyst for this project, how would you have determined the requirements for the device? Be specific and list several questions you would have asked.

3. What are the primary functional requirements for the device and associated system?

4. What are some of the non-functional requirements?

5. All systems are imperfect, in that there are features and functions that may not be technologically or economically feasible, or whose inclusion would prevent a reasonable time to market. Can you think of potential improvements to the device and/or associated systems? (Note, this does not need to be an exhaustive list - I am just looking for a few suggestions for improvement.)

Obviously, you will have to research this device on the Internet (or in a pharmacy or other setting). Please cite your references (e.g. provide a link to materials you used).
