PROBLEM

Nursing home residents — most of whom live with cognitive limitations, sensory decline, and a deep need for autonomy and connection — have no tools designed to support their daily quality of life. Every existing solution is built for short-term hospital care, and blind to the realities of long-term living.

SOLUTION

SOLUTION

SOLUTION

A purpose-built interface for nursing home residents that restores autonomy, strengthens connection, and adapts to the real physical and cognitive needs of long-term care.

  • Elderly-first, non-stigmatizing design

  • Schedule, medications, and activities

  • Room controls and privacy

  • Nurse call and symptom communication

  • Family and social connection

The name Pebble comes from the project's central inspiration: the zen garden. Visually and philosophically, a zen garden is defined by calm, intentionality, and the absence of noise — each element placed with purpose, nothing superfluous. A pebble doesn't demand attention. It sits quietly and does exactly what it's meant to do. That became the guiding principle for every design decision in this interface.

Prototype

Test

I conducted a literature review across eleven peer-reviewed sources, synthesizing findings on elderly technology adoption, cognitive decline, digital accessibility, and long-term care design. My goal was to move beyond assumptions and build a research-backed map of unmet needs.

70% of long-term care residents have cognitive limitations, most often dementia (Bowles et al., 2015)

Standardized technology "paradoxically contributes to a decrease in residents' independence" (Jøranson et al., 2025)

Older adults prefer technology "disguised as an everyday device" — not medical equipment (Mannheim et al., 2019)

Ten resident needs emerged from the synthesis: autonomy and independence, social connection, cognitive and memory support, safety and health monitoring, pain communication, dignity and non-stigmatizing design, privacy and control, personalized information access, accessible design for sensory decline, and human connection over mechanization.


The research also surfaced a critical principle that shaped how I scoped the interface: technology in care settings should be an additional tool for accessing human relationships, never a replacement for them. This directly informed the decision to exclude entertainment features that might substitute for social engagement — if there's a yoga class at 2pm, Pebble's job is to remind you to go, not to stream a yoga video instead.

INTERACTIVE PROTOTYPE

SUPPLEMENTAL ANALYSIS - GOOGLE STITCH AI

As a final experiment to close out this project, I ran an experiment using Google Stitch — an AI-powered UI generation tool — giving it four prompts of increasing specificity for the same problem. Starting from a vague one-liner and ending with a fully detailed brief that included Pebble's name, philosophy, visual direction, and target user. The goal: understand where AI-generated design falls short for a population it can't actually know, and what that reveals about the irreducible value of research-driven, human-led work.

Generated a standard dashboard — home screen, video call, daily schedule, help button — with large text and high contrast. Named it "The Guided Sanctuary." Functional on paper, but entirely templated. The design could have been for any age group; there's no evidence the AI understood who it was actually designing for.

PROMPT 02 — ADDED CONTEXT

"...help them feel more independent and in control...simple enough for someone not comfortable with technology, and calming rather than overwhelming."

The language around empowerment and independence appeared in the AI's descriptions of each screen. The output was structurally identical to Prompt 1 — same navigation, same screens — with a slightly warmer tone in its copy. Adding emotional intent to the prompt changed how Stitch talked about the design, not how it made decisions.

Stitch introduced a "Tactile Sanctuary" theme and warmer visual palette. But the resulting interface was disorienting — even to a tech-savvy reviewer. Specifying the user's limitations in a prompt is not the same as designing through an understanding of those limitations. The AI applied accessibility as a style filter, not as a lens on behavior.

"Design a bedside tablet interface called Pebble...warm and organic — natural textures, muted earth tones, botanical illustration accents...every interaction should require as few taps as possible."

The most refined output — a "Pebble Hearth" design system with botanical accents, earth tones, and all five requested screens. Visually closest to the brief. Yet the gap between Prompt 1 and Prompt 4 was still smaller than the gap between my first and third round of sketches. The underlying structure, navigation logic, and interaction patterns barely changed across all four generations.

TAKEAWAYS


  1. Prompt depth ≠ design depth

Even a fully detailed brief produced outputs that differed more in surface aesthetics than in conceptual approach. The structural logic of all four generations was nearly identical.


  1. AI designs for a generic user

Stitch could describe its audience in words but couldn't design for them in practice. Knowing a user profile is not the same as understanding lived experience — and that gap showed up directly in the usability of the output.


  1. Narrow variation range

Across four prompts, the fundamental layout logic, interaction patterns, and visual language converged. AI tends toward the mean; meaningful design often requires deliberate divergence from it.


  1. Aesthetics without empathy

Stitch could apply "warm" or "botanical" as a visual filter. It couldn't make the decision to frame privacy controls as personal preference rather than medical settings — because that required understanding dignity, not just aesthetics.


AI tools like Stitch are genuinely useful for rapid scaffolding, but this experiment reinforced something the research literature kept returning to. Designing for vulnerable populations demands embodied understanding. This understanding is a result of research, experience, and real-life interactions, something that AI has yet to replicate.
