Problem
Loneliness among seniors is a growing concern.
Many solutions assume that connecting people to other people (socializing) is the primary need.
We wanted to test this assumption and understand what older adults actually need to alleviate the loneliness.
How might we help older adults feel emotionally connected and supported,
addressing their feelings of loneliness through human-centered interventions?
For Whom, with What, and How to Solve Seniors’ Loneliness
We assumed that a variety of factors affect the loneliness: decreased mobility, inaccessible transportation or public spaces, loss of loved ones, and diminished social circles. While physical isolation contributes to this, emotional loneliness can persist even when social interactions are present.
To narrow down the scope, we set up three research questions to explore the context behind their loneliness more deeply.
💡 Who to focus on: What are the defining traits of older adults who face the greatest challenges with loneliness?
💡 What we should solve: What are the core emotional drivers of loneliness among older adults?
💡 How can we help: What types of social, emotional, or environmental interactions do older adults find most fulfilling in alleviating loneliness?
Mixed Methods Research:
Surveys + Qualitative Interviews
We ran a quantitative survey with total 132 participants aged 60+ (Primary age groups: 61–65 at 33.8%, 71–75 at 24.6%) and followed up with 6 in-depth interviews.
The survey provided statistical insights into the "what" and "how often", while the in-depth interviews delved into the "why" and personal experiences, offering rich context to the quantitative data.
Quantitative Surveys
  • 132 participants, aged 60+
  • Conducted online via Google Form.
  • Focused on 3 pillars:
    1) Status and Causes of Loneliness
    2) Social Activity and Preferences
    3) Technology Acceptance and Expectations
Qualitative Interviews
  • 6 in-depth interview.
  • Conducted online via phone call or Zoom.
  • Explored core emotional drivers of loneliness and fulfilling interactions.
  • Provided critical context to survey findings, revealing paradoxes and psychological barriers.
Quantitative Key Findings
While more than 7 out of 10 seniors are not socially isolated and maintain a regular active presence, approximately 41.5% still experience feelings of loneliness.
  • Primary Causes of Loneliness: "Lack of social connection" (24.6%), "Loss of close connections" (20%)
  • Top social activities: "Exploring/learning" (70.8%), "Chatting" (58.5%), and "Simply enjoying others' presence" (50.8%)
They also showed high openness to new technology, with 93.9% responding positively or neutrally to learning it.
  • Anticipation for the technology: "Assisting in event discovery" (60%), "Connecting with acquaintances" (44.6%), and "Fostering new connections" (43.1%)
In-Depth Interviews
To gain a multi-dimensional understanding of seniors' lives and social needs, the qualitative interviews were structured around the following three key pillars. All 6 participants were recruited from survey respondents who self-reported as "feeling lonely".
  1. Social Landscape & Connectivity
    Evaluates the current state of social interactions, support systems, and preferred communication methods.
  • Key Focus: Living arrangements, changes in social life over time, and the "why" behind preferred connection tools (e.g., phone vs. in-person).
  1. Experience of Loneliness (Triggers & Coping Strategies)
    Identifies specific emotional triggers and the effectiveness of current self-soothing strategies.
  • Key Focus: Recent experiences of loneliness, specific events that contribute to isolation, and the role of personal items in providing comfort.
  1. Engagement & Barriers to Connection
    Examines the motivations for socializing and the physical or psychological obstacles that prevent participation.
  • Key Focus: Daily routine, Fulfillment gained from activities, methods of discovery (word-of-mouth vs. online), and unmet needs within the community.
Key Findings
  1. Loneliness is most severe among seniors who failed to build new reliable connections after loss of key relationships.
100%
of lonely interview participants felt frustrated after efforts to find like-minded individuals through senior centers or online.
66%
of lonely interview participants cited losing key relationships (e.g. sister, husband, friends) as a major factor contributing to loneliness.
2. Root causes of loneliness are "Inability to share their true thoughts", primarily driven by lack of close social connections.
100%
of lonely interview participants mentioned that the absence of people with whom they can share their genuine thoughts and emotions contributes to their feelings of loneliness.
83%
of lonely survey respondents cited a lack of social connections as their primary reason for feeling lonely.
“I think part of my loneliness comes from the fact that I don't have a better connection with my wife. She has no interest in most of my hobbies. There are certain topics within my actual family that I am inhibited from discussing, either they don't want to hear it or it upsets them, and I get negative feedback and that kind of stuff, but certainly not outside my family.”
– 69-year-old male
3. Core solutions for loneliness relief are "Uplifting daily routines" and "Opportunities for deep, interest-based connection".
100%
of lonely interview participants mentioned that regular daily activities (e.g. gardening, walking the dog, cooking, listening to the music) help them alleviate the feeling of loneliness.
66%
of lonely interview respondents actively used online platforms (e.g. Facebook, Whatsapp, Twitter) to share their genuine interests (e.g. politics, basketball).
Many seniors remain emotionally isolated due to a lack of safe spaces for authentic self-expression. There is a clear opportunity for a solution that provides constant emotional presence within their existing daily routines.
Synthesizing insights, ideation, and new design question.
With this new insight, we reframed our design question to address the internal barriers seniors face.
How might we encourage seniors to share inner thoughts and feelings based on lived experiences to reduce emotional distress?
Solution: A Companion Lamp That Hears You
We came up with the idea of a lamp that always listens to your stories, whenever you want. We were reminded of how simple phrases like “How are you?” can act as a trigger for expressing feelings. What if an AI asked you instead of a human?
We found this particularly promising because it aligns with our solution goals: accessible interface, offering feedback, fostering connection, and usage in a familiar setting.
Voice-Interaction
Voice interaction is the key to this solution, making it accessible regardless of technical proficiency. Voice is also a much more humane medium than mere text or digital interfaces.
User Scenario
We developed two major scenarios that routinely encourage natural expression of feelings.
  1. Check-In Routines: The lamp proactively initiates wellness check-ins during the morning and evening, or at the user's preferred times.
Interviews showed that for older adults, maintaining a consistent daily routine or having regular contact with someone helps prevent feelings of loneliness. Usability study participants also prefered greetings to occur routinely at pre-set times. Thus, Buddy Light creates a routine of sharing and will initiate the conversation at pre-set times for morning and evening check-ins, ensuring users are prompted to share thoughts and feelings.
2. On-Demand Conversation: Users touch the lamp to initiate the conversation, whenever they want.
Physical Interaction (On-Demand Support): For moments when support is needed outside of pre-set times, Buddy Light offers a tactile, "always-there" presence. Instead of opening an app, users can initiate a conversation simply by touching the top of the lamp. This satisfies the user feedback that a companion product should be physically accessible and offer immediate support whenever the user needs it.
How Research Informed the Solution
Physical Presence - Lamp in a Familiar Home
Our research identified several critical barriers to social engagement for older adults. Survey data showed that 18.5% of respondents avoid social activities due to a lack of interest, while 24.6% are restricted by physical and mobility limitations.
By designing Buddy Light as a physical lamp for the home, we meet seniors in their most comfortable space.
This approach addresses mobility concerns and provides a low pressure, non judgmental environment that significantly reduces social anxiety.
Buddy that always hear you - Embedded AI conversation agent
All participants from in depth interviews revealed that socializing with new connections "draining" because of the constant need for caution and the fear of judgment. Research also revealed that some prefer privacy or feel that others, including family, are uninterested in their true thoughts and hobbies.
With 93.9% of seniors expressing comfort in learning new technology, Buddy Light bridges this gap by offering an AI-powered companion that acts as a safe, non-judgmental space.
5 Design goals for the solution
  1. Empathy in Interaction: The design should provide accessible and well-trained voice responses that can empathize with the user’s emotions and thoughts.
  1. Routine Engagement: The design should provide routine interaction to build a habit of sharing.
  1. On-Demand Availability: The design should provide on-demand interaction whenever the user needs it.
  1. Initiation by Design: The design should take initiative to engage with users.
  1. Seamless Integration: The design should integrate with the users’ life or familiar environment in a non-intrusive way to increase comfort when interacting with it.
Mid-Fi prototype
To test the core interactions of Buddy Light, I collaboratively developed a functional mid-fidelity prototype that integrates AI conversational intelligence with a physical form factor.
  1. AI Conversational Engine & Voice Design
  • The "brain" of the prototype was built using GPT-3.5, customized to act as an empathetic and non-judgmental companion.
  • Natural Language Processing: The agent was fine-tuned to prioritize emotional validation, avoiding rushing to conclusions or solutions.
  1. Voice Synthesis
  • I tested various AI voices from ElevenLabs to generate a calm, soothing voice specifically designed to
  1. Voice-User-Interface flow
  • I developed two major interaction flows by Wizard-of-Oz prototyping: Voice-based Setup (Onboarding) & On-demand support.
  1. Physical Form Factor
  • Hardware Composition: I and other team member integrated a Bluetooth speaker and a color-changing LED lamp into a glass enclosure to mimic the intended aesthetic and functional "Buddy Light" form.
  • Ambient Feedback: The lamp was programmed to use light transitions and music as sensory cues before initiating conversations, making the technology feel less intrusive.
How the prototype works
  • Interaction Flow: When a user speaks near the lamp, a connected demo computer processes the audio through the GPT agent in real-time.
  • Audio Output: The AI’s response is then transmitted back to the lamp via Bluetooth, allowing the lamp itself to "speak" to the user.

We successfully showcased the final solution on December 2nd, 2024, receiving highly positive feedback from over 100 participants.
Takeaways
I realized that the insights we uncovered about loneliness are not exclusive to seniors. They tap into a fundamental human condition applicable to all ages. True recovery from loneliness begins with addressing emotional isolation.
Exploring AI’s potential to provide authentic human support was a deeply fulfilling journey. Moving forward, I aim to validate this solution through senior-centered testing.
This experience of designing and prototyping a multimodal product has fueled my passion to deep dive into the future of AI multimodal interactions.
