Record these as a series of high-level takeaways, focusing on the usability problems you saw, rather than what each participant did. For instance, you might describe how you had some learnability issues with your prototype, as evidenced by users B and C clicking all of the menus to try to find option X.

Prototype Photos

Briefing

Patient:

• You are a patient taking several drugs at different times of the day but sometimes you forget about them.. You want to keep track and be reminded to take them correctly by using this mobile app.

Doctor:

• You want to hear immediate feedback from your patients about their medications. The doctor version of Take Your Pills allow you to communicate with your patients and check their medications records.

Scenario Tasks

Patient:

• You want to add Drug A to your medications. You take 2 pills of Drug A everyday at 2PM and 6PM.
• You want to add Drug B to your medications. You take 1 pill of Drug B every 5 hours starting from now.
• You realized that you actually made a mistake about Drug A. You want to remove it from all your medications.
• You are having a headache for no reason. You are not sure if this is related to any medicine that you are taking. You want to contact your doctor.

Doctor:

• Check if there is any new notes from your patients.
• It seems that your patient Eric is having a headache. You want to check his medication history especially that of Drug C for this week.
• You think Eric is having his headache because he missed Drug C. You want to tell him about it.
• You want Eric to start taking Drug E.

User Observations and Feedback

Below are our observations from each user.  We also asked each user for feedback after they have completed all the tasks.

User 1
Observations:

• Patient
  • did not notice the 24-hr time selector
  • clicked on DrugA to edit (mis-functionality: clicking on DrugA button prompts users whether they have taken the drug at an earlier time, missed the drug, or will be taking the drug now)

Feedback:

• what about users who do not want to interact every few hours with app (busy lifestyle and just wants to deal with app like once a day)

User 2
Observations:

• Patient
  • did not notice the 24-hr time selector; realized and then selected correct time
  • clicked on DrugA to edit (mis-functionality: clicking on DrugA button prompts users whether they have taken the drug at an earlier time, missed the drug, or will be taking the drug now)

Feedback:

• how to get chat message from doctor after moving to a different page, any notifications?
• if patient sees multiple doctors, is there privacy/sand-boxing among doctors and drug info?
• Took it/missed it/take it now - confusing wording between "took it" and "take it now" (what's the difference between just took it and taking it now?)

User 3
Observations:

• Patient
  • did not notice the 24-hr time selector; realized and then selected correct time

Feedback:

• what to do if "miss" many drugs (ie did not use app to log several drug-taking events, for example on a weekend trip without wifi or batteries)
• how to clear all
• are there alarm settings
• what about users who do not want to interact every few hours with app
• suggests if press drug button, it selects, and edit/delete buttons show up for selected drug

Prototype Iteration

We made changes to our prototype after our first round of testing, mostly to simplify the user interface and clear confusions users have.  Here is a list of our changes:

Patient

• "Today", "My Pills" "Add Pills" were condensed into one main page. User can now both edit the drugs (including add and delete) and record actions with the drugs (take it, missed it) on the same page.
• Removed "current date and time" from the time bar since it is obvious. Time is now in the bar that has "contact doctor" and "sign out".
• Clicking on the medicine now leads the user to the info page of the medicine, where user can edit and delete that medicine.
• Recording actions with medicine is now handled with a pop up box when user clicks the check box on the left of the medicine.
• Changed the "add drug" page. Now all three types of drugs are handled by one dynamic page that changes when selecting different options. 
• Add AM/PM to drug time "widget".
• In "repeat every several hours" option, now "minutes" only has "00" and "30".
• Clicking the "pencil" icon on main page now leads to "edit drugs" page.
