Mobile App Participatory Design in Action


Published on

These slides are from a 2014 virtual conference presentation for public health informatics professionals. The focus is on the use of participatory design methods to design and develop a mobile app for emergency first responders to use in communicating with people with communication challenges, including things like having limited English proficiency, being hard of hearing or Deaf, or experiencing cognitive delays.

  • The paper based tool and app were developed based on a user-centered design (UCD) process, involving end-users as co-creators in every step.
  • Participants were asked to complete tasks using the book or mobile app, like “Tell her that she needs to leave the shelter at 9:00 a.m.” and “Ask him to tell you where he is hurt.”
  • Ana, not sure if we want this, so feel free to delete! 
  • Public health professionals struggled with knowing which icons to show first during prototype and dyadic testing.Because of the iterative design process we were able to made changes based on what we heard and test them out. We not only saw that people were struggling, we also heard in in-depth interviews another reason for creating prompts, to help PHPs communicate messages in a clear order that people were looking for.We also heard, during in-depth interview and usability sessions from disability advocates and individuals with communication challenges was that trust was a barrier, and that a person would want to know what type of emergency was happening before being asked to leave their homes.
  • User GroupThis was a challenging group to test with – the health professionals often had limited technical knowledge, and the people with communication challenges struggled with… communicating. We had interpreters for language and ASL, but the cognitively disabled participants presented unique challenges. For example, in one instance we had a gentleman who couldn’t speak and used his own set of icons to communicate. In order to assess and debrief a task, he used hand motions and pen and paper. It was quite the experience. (In case you’re wondering: he could complete the task and even made up his own scenario that the health professional was able to understand.)User GroupPublic Health Professionals: Technical challengesIndividuals with access and functional needs: Communication challenges
  • Hey Ana – please feel free to beautify! I couldn’t find any examples of end slides 

    2. 2. Abstract Join us for a discussion about the process of developing “Show Me,” a communication tool for emergency response.
    3. 3. Objectives + Identify at least 3 advantages of using participatory design for public health communication materials. + Identify at least 2 participatory research methods that can be used to inform the design of public health communication materials. + Describe at least 2 of the challenges of using a participatory design process.
    4. 4. Agenda + What is the significance of the Show Me app? + How did we achieve our goal of using participatory design for Show Me? + What challenges did we encounter in the process? + Conclusion and questions
    5. 5. What is the significance of the Show Me app?
    6. 6. Project Design and develop a paper-based tool and mobile app to facilitate communication in emergency response situations between public health professionals and people with communication challenges. Shelter Dispensing Site Shelter in Place Evacuate
    7. 7. Population/Audience + Individuals with communication challenges: + Hearing impairments + Limited English proficiency + Cognitive delays + Public health professionals, including: + First responders + Emergency medical personnel + Public health nurses
    8. 8. Significance of the Show Me app
    9. 9. How did we achieve our goal of using participatory design for Show Me?
    10. 10. User-Centered Design The UCD process included: + In-depth interviews + Focus groups + Usability sessions + Dyadic interviews
    11. 11. In-Depth Interviews (n=17) We conducted in-depth interviews with key stakeholders, including: + First responders + Emergency personnel + Disability advocates + Personal care assistants
    12. 12. Focus Groups (n=10) We conducted 5 focus groups with individuals with communication challenges and 5 with public health professionals and first responders.
    13. 13. Usability Sessions (n=15) We conducted 12 icon feedback and card sorting sessions with individuals with communication challenges. We conducted 3 prototype testing sessions with public health professionals.
    14. 14. Dyadic Testing (n=9) In a dyadic usability session one public health professional and one person with a communication challenge completed tasks using the paper tool/app together.
