Design for the coming future


As life expectancy sharply increases in developed countries, there are more than 30% of senior population lives alone in United States. However, physical degradation, cognitive impairment or social isolation might pose risk in their daily activities. Self care and social wellbeing have gained increasing importance in the life of seniors to live independently without worry and age with vitality.

My role

During my Integrated Product Design course, I was part of a team of 4 with students from industrial design, engineering and business school to design and market a product in a simulated market environment, which is very similar to running a startup and pitching our product in a kickstarter campaign at the end. I led the entire UX design and research process and involved in electronic prototyping, website design and marketing design for the final tradeshow.


How might we support social wellbeing of the senior and enable them to live independently with confidence?

Product at a glance

Connections beyond distance

Kasvi, a sleek home décor product, initiates meaningful interactions between seniors and their loved ones without the barrier of physical space. During our research, we identified that social wellbeing of seniors has great demands, but it was rarely the focus of the products in the market. Empathizing with the target users, our design, kasvi, provides an ambient way to interact with each other at home through the hobby of gardening. It was the most-demanded product among 6 teams voted by over 400 tradeshow visitors.

Design Process

Envision shipping product to the market

Competing in a simulated market space of 6 teams, we conducted rapid product development cycles from researching market potentials, validating design concepts, fabricating tangible prototypes to marketing products in a tradeshow. Along the process we also went through 3 design reviews from a panel of design professionals, business specialists and public health practitioners.


Understand user needs and market potentials

As the design prompt of this class, designing active technology for senior citizens, targets a broad group of users, we started out with interviews and competitor review to understand the pain points and desires of seniors’ daily life. We conducted 20 user interviews, including 16 senior citizens and 4 caregivers, and observation that provided insights of core user needs and market potentials.

Affinity diagram & consulting model

To synthesize the data collected and find out the common themes, we leveraged affinity diagram and consulting model to frame 4 essential needs:

Illness prevention

Health maintenance

Caregiver support

Aging with vitality

Personas & user journey

Based on the data collected, we created personas, user value statements and user journey to frame the needs and context of our target users and identify the touch points of design. Our personas were senior adults of varied mental and physical capabilities, however, few traits shared among them are living independently and aging with vitality and dignity, which reflected the main themes from our research.


Brainstorm with multi-disciplinary perspectives

Instilling UX methods into the team, I led a brainstorming session that strived to create an environment where team members could get inspired and build on top of each others’ ideas. We came up with over 30 ideas in a half-an-hour session and grouped ideas of common values into 5 design concepts that spanned across the 4 essential needs discovered during research.


Validate Design with stakeholders and users

Concept card testing

We tested the design concepts with 2 rounds of concept card testing. In the first round of testing, we presented potential customers with more abstract description of concepts. 5 concepts plus 2 exisitng products were tested. This informed us the willingness of purchase of each design concept and provided further design inspirations. We re-iterated on few design concepts for the second round, which gave us more concrete feedback on design details and product functionality.

Value statement scoring

To communicate values of different stakeholders and seeking consensus, we discussed the value statements with all team members to rate each statement according to our team values, passion, technical capabilities and market potentials. This helped to resolve conflicts before diving into fabricating the product, and put the team on the same page.

Identify the intersection of team values and user needs

Cross referencing the results from value statement and concept tests, we created a statistical map to find out the intersecting point that displays high market potentials and us valued by the team. It turned out three product concepts ranked similarly on the map, which are self-care, connections with others and continuing hobbies, and self care ranked the highest in out team value statement. However, concept tests with users showed the highest user demands and market potential came in connections with others. Eventually, our team decided to design for social connections as that’s the most urgent needs from our users, while incorporating inspirations from the other two.

Product fabrication

Prototype early, iterate quickly

Product brief

We iterated on our design concept about social connections. Incorporating user feedback and input from design review panel, we defined our product brief to guide the focus of design and kept iterating on the forms and functionality. We also iterated and further narrowed down our product brief to feature level and brand impression based on design review and testing feedback.

Going tangible

We began prototyping early on to test out design details and potential technical issues. We played around forms and materials for different fidelity. Prototypes were made from cardboards, 3D printing, Arduino components and other materials at hands for realizing the design concepts.

Conjoint analysis & costing model

We also conducted conjoint analysis to help evaluate the cost and needs of certain design features. We designed 7 sets of cost and feature combinations and 2 evaluation sets to assess the validity of the response set, and similar to card sorting, asked users to sort the rank of the feature-value pairs. The analysis helped up to define MVP by understanding that users were willing to pay more for simple light notification, while additional functionality such as sound and shut-down option received relatively less selling potentials. During our design review, the panelists also suggested cutting down flurry functionality and focused on the storytelling of the entire experience. We then proposed the costing model based on our finalized product design, which predicted the mass production costs and profit margin of our product.

Final Design

kasvi, grow the good moments together beyond distance

kasvi is a paired home decor device that aims to be a conversation starter for initiating warm, meaningful interactions without the barrier of physical distance. We defined an entire brand concept around the product to set ourselves unique among competitors. We created a promotional website, video trailer and design the trade show experience for customers.

Demands from the tradeshow

We are the ”Most-demanded product” across all six teams, where more than 50% of the tradeshow customers bought our products with virtual cash

Storytelling as part of the design

Besides building the product, we designed an entire story, including tradeshow decor, packaging, swags and more, to make our product relatable to customers

“I can imagine using this product with not only my grandparents.”

Build a network with kasvi

Inspired by user and panelist feedback, we came up with some crazy ideas of making kasvi more than interacting with each other. One idea well-received by the crowd was enabling multiple kasvi devices to be connected together. Devices could be assigned with different color codes to build a network with social circle.


Design is collaborative

The simulated market environment allowed me to further develop my product thinking skills. The process of developing kasvi involved not only designing good user experience but also identifying opportunities among other competitors, making trade-offs for production and cost and creating compelling storytelling to customers. Cross-functional collaboration also took great part in this project, where we resolved conflicts, made compromises and set clear team values, to achieve our final design.
