THE CHALLENGE

Pregnant women need a better solution to support their maternity health and weight management.

THE PROCESS

(1)Developing goals, personas & storyboards; (2)Creating low to high fidelity prototypes (3)User testing & design iterations

THE SOLUTION

Using an interactive voice-based technology Alexa and the corresponding App for easy daily life assistance.


Research the Landscape

    Literature Review

    • 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.).

    Expert Interviews

    • 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.

    Marketing Research

           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:

    1. Mobile apps
    2. Web apps
    3. Alexa skills

    There are two overall themes for these applications:  

    1. Comprehensive tracking and nutrition guidance
    2. Exercises

    Design Process

    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.

    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.

    User Testing

    Design Impact2.png

    Four Main Goals of User Testing

    1. Figure out what functionalities we should include in our design

    2. For each scenario, what is the preferred method of input and output (email, text, or voice)

    3. What are some extra scenarios that are important to users but we ignored

    4. 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).
