Product Designer | Research to hi-fi clickable prototype
Project spanned over three weeks, part-time, as an independent case study
Design of a B2C mobile digital health app: a therapeutic tool used to facilitate memory and recall in adult patients with cognitive communication and language deficits
Today’s healthcare professionals are pressed for time in facilities that are unable to keep up with society’s technological advances. These are difficult issues to deal with when trying to give patients the best care possible. Having a background in the medical field, I tackled these problems in the context of a specific therapeutic tool used by speech-language pathologists: memory books.
How to create a modern, efficient, therapeutic tool that adequately serves patients, involves caregivers, and save clinicians’ time?
I designed Vivid from the initial concept to the final hi-def clickable prototype. This included initial research, wireframing, user testing and branding.
Improved product navigation and user success rates across targeted tasks. Qualitative feedback from users included positive comments such as, “I can see this being really helpful, you should make it!”.
Vivid: A Memory Aid. Above: User Flow for Photo Selection.
One-on-one interviews with five individuals (three healthcare professionals and two patient family members)
Increased family involvement
Up-to-date, digital therapy tools
Therapeutic materials for the “modern” age
Time sensitive (limited minutes for therapy sessions)
Following initial user interviews, a few problems consistently came up in conversation:
Lack of modern, efficient, digital, therapeutic tools for patients with cognitive communication and language deficits
Barriers to creating physical therapeutic memory books for patients, including lack of access to photos, time or information
Needing more ways to know how to involve family members or caregivers
After speaking to potential users regarding their desires and pain points as well positing the idea of a digital memory book (and receiving positive feedback), I analyzed what current market had to offer in terms of therapeutic memory book tools.
Memory books are a tool that clinicians use with patients as a functional aid for recall. They can be used in order to rehabilitate patients to remember information (ex: patients with brain injuries), or as a method to increase quality of life (ex: patients with dementia). Usually they are printed out and written on in sessions. Provided work with a trained medical professional, they have been proven to be efficacious.
Competitor Research and Analysis
There was an evident gap between memory books made on shutterfly and snapfish vs. traditionally-printed therapeutic memory books. Current digitized tools lacked medical family education, certain therapeutic elements, as well as ease of access for printing.
Digital therapy tools had no photo or memory book options and direction was necessary from a medical professional.
I created a digitized, therapeutic memory book as an iOS mobile app, enabling:
• Easy access for family and medical professionals to patient photos and information
• Opportunity for increased family involvement
• Reducing clinician time for session material preparation
• A modern therapy tool for use with patients
Based off of competitive analysis and user research, I created low-fi mock-ups keeping the following considerations in mind:
• Ability to print out a memory book in addition to the digitized version
Medical professionals wanted to be able to use a tool that reached a wide demographic of patients, specifically different ages. By being able to have to option of printing out a book or using it digitally, the medical providers, patients or family can choose the medium that is best suited for the patient. For example, a young, tech-savvy individual may prefer using the app on a handheld device while an geriatric patient may prefer the printed book.
• Include caregiver education during onboarding
The majority of users agreed that having caregivers involved in the therapy process would be beneficial. Onboarding was included to make the app easily understood and digestible for caregivers
• Maintain a therapeutic/medical perspective
While caregivers can use the app, the therapists would be the facilitators - using it in sessions and directing the caregivers. Therefore, the medical perspective would still exist, however it would be digestible enough for caregivers to better understand the use for the memory book as well as choose better options for the patient at home.
Usability Testing: Interactive Prototype
Initial one-on-one prototype testing with follow-up interviews. Application success was judged across three task criteria along with overall satifaction and ease of use ratings as reported by users. Prototype was developed and tested via InVision.
Prototype success was measured across three main tasks and various subtasks:
Task 1: Log-in and Create a Memory Book
Task 2: Make Edits to Memory Book
Task 3: Successfully review and export Memory Book
InVision prototype was tested with three individuals (two in-person, one digitally)
All tested users reported:
• Confusion while navigating the application
-how to move back and forth between pages
-how to exit certain screens
• Confusion how to use certain application features
-calendar and daily routine page
-use of “hide” button
Positive validation included:
• Users thought that this would be a great way to get family members involved
• Medical professionals agreed that it would be a good tool to have for therapy
I added onboarding pages in order to decrease user confusion while navigating between pages and using application features.
Menu redesign to improve navigation. I created a “number of photos” and an “add page” menu option to increase visibility and ease of access.
“Review Book” Refinement
Redesign of the “review book” feature. I decreased navigation confusion and user overload by simplifying presented information. I added buttons instead of icons to increase navigation clarity.
Removal of “Hide” Feature
Users did not understand the “hide” button’s function and found the feature was unnecessary. Removal of the “add” button due to the addition of a footer menu.
End Results and Takeaways
There was an improvement in task completion and navigation ratings after the new prototype was re-tested as 5/5 users were able to complete presented tasks. Something new that could be added in future redesigns is a way to track patient recollection of information and progression as remarked by the above user. All tested users agreed that Vivid would be a great way to get the family involved.
Digital health funding continues a strong trajectory in 2018. Designers can continue to service and help patients, caregivers, and clinicians by using technology to solve new problems. I enjoyed doing my part, by applying my knowledge of the health space to help address an issue for those involved in a patient’s brain rehabilitation.
