Industrial & Sympathetic Design

What is it?

A dual-function message sender and night light

The Problem

In long-distance relationships, communication is often reduced to screens, text, and notifications. While efficient, these modes lack the physical and emotional nuance of touch.

Proposed Solution

Core Intention

Translating touch into presence across distance.

This project responds by exploring how product design can:

  • reintroduce touch

  • create subtle, ambient communication

  • support emotional connection beyond screens

01

The user places their finger on the small pebble, ergnomically designed to sit in the palm and invite touch

02

The device detects their heartbeat and transmits it to its paired light which begins to pulse softly, mirroring that rhythm.

03

What would normally be a message becomes something quieter:
a shared, ambient signal of presence.

An intimate way of saying “I’m thinking of you.”

User Journey

Making Journey

Prototypes

Development focused on:

  • Natural interaction

  • Subtle feedback

  • Emotional resonance

The project combined:

  • Arduino programming for biometric sensing

  • Glassblowing methods for light diffusion

Key Design Decisions:

Tactile Form
The weighty glass pebble shape invites holding, reinforcing comfort and familiarity.

Sympathetic Interaction
The object responds to human input (touch, heartbeat) rather than commands.

Material Language
Wood and glass balance warmth and fragility, supporting the emotional tone of the interaction. And bicarbonate bubbles in the glass to diffuse the light gently.

Crafted from recycled soda-lime glass and locally grown and felled oak timber from Scottish Woods in Fife.
