Brief

 

As our population ages, many adult children are becoming more involved in their parent’s care. Parents are taking more medication so an added stress with a parent who is still on their own is making sure they take the right medication and at the right time. Automatic medication dispensing devices are currently available to help a patient take the right medication at the correct time.  However, if a medication is missed, a caregiver such as child does not have a useful way to monitor their parent’s medication.  

 

By this semester-long project, I designed a system of devices to advance the health management of the elderly:

 A  mobile app for the caregiver to monitor medication dosage

A wearable smart watch to keep track of patient‘s medication

A smart dispenser to remind patient about medication dosage.

MOBILE DESIGN
01
Problem, affinity mapping, persona, prototype

Problem Space

Keep tracking of parent's medication dosage isn't easy, especially for modern people with a busy work schedule.  The elderly may forget to take their medicine on time as they may have memory impairments, mobility limitations, or other disabilities that further complicate the process, exposing them to potentially dangerous errors.  ​

Design Goal

Therefore there is a need for the caregivers to remind their parent to contact with their parent when they havn't take the medicine on time. And the parent at home also need to get help with some smart devices to remind about medicine taking.

Based on the problem scenario, I created the persona of the caregiver to identify their pain points and goals.

 

Affinity Mapping

Before jumping to design the device features, I  did affinity mapping to understand user's need and group them into related categories.

Sketching

After analyzing the user's need and grouping them into 9 categories, I brainstormed for design solutions and then sketched them on paper.

Hi-fi Prototype

01

Connecting the pill dispenser to the App 

The MedMinder device will have its machine number written on the device which the user will type in to get the access code. Once the device is connected to the app, the medication status will be accessed by the caregiver.

02

Push alarm notification

When the patient forgets to take his/her medication, the caregiver is notified via phone’s push alarm notification. Then, the caregiver will have the options to either call the patient or find out more about the details

03

Medication & Activity

Caregivers could use the app to set up a medication schedule and oversaw the elderly medicine taking activity.

User Testing

Sarah needs to take medicine herself regularly and her parent also needs to take complex medicine.  From the start, she thinks the idea is good, as she has an issue with remembering to take medicine. She thinks the layout is straightforward, and the design contains the feature she wants to have a medical care APP. But she thinks a dashboard will be better to show the activity of taking medicine condition as the first page rather than the alert page.

 

Another participant Clara likes the color of the APP, as for the medication APP, the color of blue gives her a sense of trust, and she thinks each function is clear. She thinks the APP cover all the function a user need to check with the medication activity.

Her main feedback is on the alert page, she thinks the “remind me later” button is not necessary when the user comes to the alert page to react to the alert.

02
WEARABLE
interaction design

I then created a smartwatch/band interface for the elderly to be able to get reminded of the medication. The smart watch can communicate the following information:​

  • when to take the next medicine

  • additional message if the medicine is missed

  • review of upcoming and/or previous medicines

  • current time

The Medminder smartwatch allows the user to keep track of their past and upcoming medicine intakes through connecting with the Medminder pill dispenser and caregiver’s phone.

03
DEVICE DESIGN
hi-fi prototype, interaction design

Further, I designed the interface of the pillbox with an emphasis on accessibility, error prevention, and ease-of-use. There are many impairments that can result from old age, illness, and medication side effects. It was important to design a device that minimized the impact of these impairments to the greatest possible extent. 

Pillbox Model

Flowchart

After analyzing both the patient and caregiver's need. I designed four functions of the smart pillbox device including alert notification, schedule, medicine, and setting. I also made the flowchart to illustrate the whole process

 

Workflow

Display photos as a digital album when them medication device is not in use

Display medicine details

Show  medicine schedule  in a coming week

Adjust alert and refill notification setting

Display caregiver's contact information

Search nearby devices to connect

See patient profile

Ring the alert to remind patient of taking medicine

When the patient forgets to take the medicine the device will call the caregiver

When the medicine is running out, it will send a notification
