Echo: Product Service System Design
We designed an award-winning product service system for people with Alzheimer's Disease and caregivers to to comfort the elder, enhance the connection among the family, and give professional assistance to the caregivers. It consists of an Echo Amplifier and a mobile app Echo.
To deliver a comprehensive product system including product mockups, an interactive functional mobile app prototype, a cohesive set of brand system, and a project book for documentation.
Theoretical and precedent research, collaborately analyzed and synthesized the outcome to insights, the iOS app design, major visual deliverables, copy writing, presentation planning, and ideating for the physical product design.

1. Identify problem space
How might we improve the wellness and connection for people with AD and assist the family as an entity?
Alzheimer’s Disease: depression, grief, fear, frustration...
Upon 3 months of research, we found that people with Alzheimer’s experience memory loss and cognition incapability due to the brain damage. In most cases, the elders’ awareness of their disability would result in depression and anxiety.
It's about the family
My grandpa is in the late stage of AD, my parents are often busy with work, and I live abroad. Because any device is complicated for my grandpa to use, my family has been experiencing huge difficulty to maintain a healthy connection.
2. Develop personas
3. Define research direction
We mind-mapped the aspects we should research for. As a result, we directed our research towards AD, brain damage, memory loss, sense of belonging and identity, and sensory therapy. We also looked deep into AD caregivers and designs for other mental illnesses.
4. Preliminary research
1. Existing designs for AD are lacking empathy in different levels.
2. Carer’s mental health have been greatly neglected.
We read books and academic journals for AD and therapies, and conducted interviews with Alzheimer’s Society of BC and design professionals of communication design, industrial design, interaction design, science, and critical design ECU and AD professor and doctor from SFU.
By synthesizing the key findings, we focused our study towards music therapy, reminiscence therapy, AD carers, and precedent designs.
5. Precedent research: Existing designs
Most of the designs for AD overlooks the elders’ social status and needs of respect. Some have poor usability and little emotional consideration. Also, we found very rare social support that is easily accessible and well-facilitated towards family and carers’ psychological health.
1. Consider patient, carers, and family members as an entity
2. Design with respect and empathy
3. Design an experience instead of a treatment
6. Develop concept based on research findings
Product service system design for people with Alzheimer’s Disease and their caregivers.
We concepted the system to be a combination of a physical product, Echo Amplifier, and a mobile app, Echo Mobile.
- The Amplifier is for the elder as a medium of music therapy, which will play the songs he/she used to like. It also delivers voice messages from carers.
- Echo Mobile is for carers to record and send the voices messages and consult psychology professionals about their own mental health and learnings of AD.
With Echo Amplifier, Guang can
- listening to the reminiscent music
- practicing finger movements by playing with the textile on the surface.
- These practices can both comfort his emotion and benefits his brain wellness.
The other family members can
- Record and send voice messages, for example, reminders of taking pills.
- Set up the play time and schedules to the amplifier, so that even if they are busy or there's a time difference, they can still deliver cares to Guang.
When Yan and Zhu feel overwhelmed or stressed when taking care of Guang, they can
- Enrol in the Echo Care programme and consult a professional therapist.
- Learn more about the illness to better understand the elder and take better care of him.
7. Key design considerations:
Empathetic and emotional design: an experience instead of a treatment.
- The amplifier should not look like a toy.
- The amplifier should not look like a medical device.
- The mobile app's UX and UI should be age-friendly.
- The system should not discourage the family visiting the elder.
8. User flow development
We constructed the user flow to inform Echo Mobile design and technical considerations. The system is simple to navigate and robust in operation. The Echo Mobile supports multiple ways to complete any task, which saves users’ confusion and learning effort.
9. Echo Mobile: iterate for an inclusive design
In order to generate the best use experience that’s friendly for people from age 12 to 60, I developed 3 iterations for the main recording function and 2 iterations for Echo Care. The intention was through user tests identify the best user flow, based on which to further refine the design to sophistication.
10. Low-fi iteration mockups and user tests
I used Sketch to quickly build low-fi wireframes, printed them on paper, cut them out, and conducted Guerrilla user tests. In the sessions, I asked each participant to do 2-3 out of all 5 mockups, so that they could compare different user flows but still provides valid input for first-time use experience.
Guerrilla paper user testing
By using paper user tests, I could easily discuss with participants and compare the use experiences for different iterations. Also, the paper cuts made it tangible to visually re-frame the information architecture by moving things around. The result shows that the user flow was not intuitive enough and there are unnecessary back-and-forth actions.
Respond to the test result:
- select the best mockup and reiterated the narration
- simplify the critical paths
- improve the IA
- iterate the integration of Echo Mobile and Amplifier
Echo Amplifier: evolves from empathy
Echo Amplifier‘s sphere shape is natural for an aged hand to hold and the wooden texture provides warmth and tactile familiarity.
According to the user tests, we decided to
- Design the sphere in different sizes considering genders and physical capabilities.
- Add small wooden balls on the surface for finger exercise, to release anxiety and prevent further brain damage. They also prevent the sphere from rolling.
- Attached a leather stripe for a secure hold.
11. Design development
The ultimate care for you and your loved ones.
Upon the core wireframes, I populated the system by building low-fi mockups and applied the brand identity to UI. Using Sketch and Invision, the mobile app was put to an interactive hi-fi prototype:
Echo Mobile: record
- See the recipient, messages, button for new message, Settings, and Echo Care.
- Change or create recipients.
- Tap the "+ new message" button and a card will slide up for recording.
- When finished, the user will name the message and set up the play time, or edit saved messages.
- After saving, the new message appears highlighted.
Echo Mobile: Echo Care
When the carer feels overwhelmed or confused, s/he could tap the speech bubble on the home screen and get help from Echo care.
- Upon first use, the user will enrol in the program
- The user will go through a series of questions about him/herself and the elder,
- According to the answers, the program will match three professional therapists.
- After selecting the suitable one, the user can chat with the therapist anytime anywhere.
Echo Mobile: Settings
All the settings for Echo Amplifier, Echo Mobile, and Echo Care are in the app.. We minimized the controls on the amplifier so the elder wouldn’t get confused or intimidated if operating incorrectly.
The card UI design: stay on the main function page. Users could easily navigate through and distinguish the different functions. The app is easy to learn and use thus users will be more willing to connect with the elder by Echo.
Finally, we put everything in a 2-min story that summarizes our concept, research, process, and showcases the final design. This little video was played in the Museum of Modern Art.
12. Brand identity
“The last thing you want people to say about it is ‘pretty’.”
Initially, I had the whole set of brand assets and mobile app designed to be pretty, which I believed could cut through the noise of beautiful designs in the grad show. However, in assessing it more, the brand looks too modern and millennial and the app is very weak in UX.
New Visual Identity
So I threw away the initial idea, started from the ground to investigate in the best practical UX and develop a brand system that corresponds to the user group and product.
As a marketing tool, there will be a website as an online store, provides tutorials and researches, and registration to the Echo Care program. We expect the website to form a community of caregivers.
In the package, we supply a charger, adapter, and a thank-you card. The card expresses our gratitude for the consumer being caring for the elder and our deep empathy towards their situation.
What’s meaningful is not the perfect outcome, but what you had to do to achieve perfection.
Although the project has gained admiration, there are challenges left behind:
Would the one-way communication of the amplifier reinforce the elder’s negative feeling of verbal disability? How to integrate two-way communication within the system?
What’s the best way for Echo Mobile to send data to the amplifier from long distance?
Upon completion, the project gain huge favour from students and faculties in ECU and great attention in the Graduation Exhibition.
In November 2017, Echo was honoured as the single winning project in North America for WGSN and ArtsThread Future Creator New York. On November 2nd, Mia and I were invited to New York to pitch Echo and deliver the acceptance speech in the Future Creator Summit, at the Museum of Modern Art.
