MedMinder is an existing pill dispensing device in the market today, which alerts patients to take their medicines on time, with the pill boxes for different days and doses lighting up and providing audio to remind them. Its aim is to help elderly patients be independent, and to give their loved ones staying away from them peace of mind. The different people in this scenario are the patient, the caregiver and the medical provider. The aim of the project was to design two parts:
The user groups in this scenario are
We came up with a user story and create low & medium fidelity mockups to illustrate how the app would be used by the caregiver.
In my scenario, Robin, aged 29, is Sophie's daughter. They live on opposite coasts and share a strong bond. After visiting her over Christmas, she realizes that Sophie's health has deteriorated and that she forgets taking her medicines, but gets irritated at being constantly prompted by Robin to do so. As the doctor's visit results in additional medicines being prescribed, Robin is worried as to how Sophie will manage on her own. A friend suggests the MedMinder device, which can be filled directly by the pharmacist. Robin downloads the application, creates an account for herself and is immediately prompted to enter the patient's data with the device number. She configures her cousin as the emergency contact, since she lives in the same city as Sophie. Other setup includes adding the necessary medications along with the days and times, mapped to the correct pill box number and setting up emergency alerts. Sophie starts using the device and is quite pleased by how unobtrusive it is.
One day, Robin gets an alert on her phone. She uses the call button from the alert to contact Sophie. As there is no response, the app prompts her to call the emergency contact, her cousin - who then checks on Sophie and reports back that she had gone for a walk and forgotten to take her medicine. Relieved, Robin modifies the reminder time for that medicine. The app also shows charts to indicate adherence, which the doctor views on the next visit. He is happy with the results, but not as happy as Robin and Sophie, for whom MedMinder has seamlessly become a part of life.
Based on the caretaker profile, and the possible concerns they would have, I created a persona.
While designing for the caretaker persona, there were a few design criteria I kept in mind:
I used ‘push left’ transitions for forward movements and ‘push right’ transitions for corresponding back movements. In places where I was moving to a new screen completely, like opening the MedMinder app from the home screen or opening a profile, I used the dissolve transition to indicate the change in context. For bottom navigation icon clicks, I used slide up transitions to give the illusion that it was emerging from the icons.
The final design was done with Sketch, with InVision for the interactivity.
I conducted usability interviews with 2 users, for both functionality and interactivity of the prototype. There were 4 tasks: Add a new profile from the profiles screen.
I made a moodboard to select a certain theme/style for the bracelet. The moodboard was a collection of pictures which was the inspiration for the look of the final device.
