BUMP: An Interactive Voice-Based Technology for Pregnant Women
T L ; D R
Pregnant women need a better solution to support their maternity health and weight management.
(1)Developing goals, personas & storyboards; (2)Creating low to high fidelity prototypes (3)User testing & design iterations
Using an interactive voice-based technology Alexa and the corresponding App for easy daily life assistance.
Research the Landscape
- In the U.S., approximately half of the pregnant women are overweight or obese before pregnancy (Rapaport, 2015).
- A significant percentage of overweight women became obese during and after child-birth (eMoms, 2015).
- With more than one pregnancy, overweight causes complications, such as gestational diabetes and difficulty during childbirth (Mayo Clinic, n.d.).
- Gestational weight gain is a serious problem during pregnancy.
- 70% of women who were moderately obese during pregnancy gained more weight during pregnancy.
- Physical activity in pregnant women is a hard nut to crack.
Through secondary research, we found a variety of applications trying to yield the same effect, a healthy pregnancy and postpartum. The main interactive applications include:
- Mobile apps
- Web apps
- Alexa skills
There are two overall themes for these applications:
- Comprehensive tracking and nutrition guidance
Goal Definition and Ideation
First, we defined goals (life goals, end goals and experience goals) and brainstormed ideas. Then we sorted out ideas with top votes from all four team members.
Storyboards with Role-playing
Scenario 1: Exercises
Scenario 2: Food and Nutrition
First Interactive Voice-based Scripts
Throughout the voice interaction, Alexa can send more information to users via Emails, make appointments on Google Calendar and receive reminders via texts.
Experimenting Different Color Palettes
Experimenting Different Navigation Bars
Four Main Goals of User Testing
Figure out what functionalities we should include in our design
For each scenario, what is the preferred method of input and output (email, text, or voice)
What are some extra scenarios that are important to users but we ignored
Where will users put their Alexa Echo and Dot (room, office, etc.)
Wizard of Oz
We used the “Wizard of Oz” testing technique. One of the team members (i.e. the “wizard”) describes different scenarios and shapes the interactions between the users and the “system” to gauge their reactions to the prototype (Hanington & Martin, 2012).
When setting up Amazon Echo or Dot, you will download the corresponding App from the store front:
