Overview

WAND is an IoT domestic orchestration ecosystem engineered to resolve the Smart Home Paradox: despite high consumer curiosity, modern parents abandon connected devices due to setup friction, multi-app fragmentation fatigue, and surveillance anxiety.

As part of Grupo 1 in our Master's Degree at SHIFTA by ELISAVA, our team (Sara Abril, Berta Rossell, José García, and Lluís Obradors) spearheaded an exhaustive qualitative discovery sprint. We conducted desk research into IoT hardware standards, interviewed 13 real heads of family across the Barcelona metropolitan area, synthesized over 100 observations into a structured Miro affinity map, and modeled validated user personas.

Rather than building technology for technology's sake, WAND reframes home automation around two vital emotional anchors: measurable monetary savings on utility bills and quiet, non-intrusive reassurance for child and home safety.


The Challenge

The smart home market is saturated with incompatible protocols (Zigbee, Matter, Z-Wave, proprietary Wi-Fi hubs) requiring separate apps for every lightbulb, thermostat, and camera. Our qualitative discovery revealed three acute pain points:

0

Field Interviews

In-depth qualitative sessions with diverse parents across Barcelona & suburbs.

0+

Verbatim Insights

Transcribed and clustered to isolate genuine parental mental models.

0

Affinity Clusters

Synthesizing security, utility bill savings, and simplicity into taxonomy.

Home Complexity

Cost & Complexity Barrier

“Parece hecho para gente rica o ingenieros, no para nosotros.”

Security vs Surveillance

Security vs. Surveillance Tension

“¿Aumenta mi seguridad o la vuelve más vulnerable a fugas de datos?”


Field Research

To avoid design team biases, we recruited and conducted semi-structured qualitative interviews with 13 diverse family units across Catalonia. We balanced housing typologies (80m² city apartments, townhouses with gardens, multi-story detached homes) and child age groups (infants of 8 months to teenagers of 13 years).

E01 • Barcelona 80m² flat

Mariona (43yo)

Two children (5 & 8). Severe worry over winter heating expenses and kids leaving corridor lights on continuously.

Need: Real-time room cost monitor
E04 • Mataró 100m² townhouse

Maria (36yo)

Three children (7yo and 4yo twins). Overwhelmed managing 6+ physical keys for cleaners, babysitters, and grandparents.

Need: Temporary digital access codes
E09 • Terrassa 280m² house

Bernat (39yo)

Infant (8mo) and dog. Highly tech-savvy but frustrated having to open 5 vendor apps just to check doors and cameras.

Need: Cross-vendor central dashboard

Core Qualitative Takeaway

Parents do not buy features; they buy cognitive relief. A smart home app is successful only when parents feel confident leaving their children in the house without worrying about unlocked doors, unclosed windows, or skyrocketing utility bills.


Affinity Synthesis

To make sense of 100+ interview observations, we created an affinity mapping board in Miro. We clustered findings into 12 thematic groupings, identifying the underlying architectural principles required to convert complex hardware telemetry into clear family interactions.

Pillar 01

Ahorro Económico

Translating obscure kilowatt-hours into plain Euros, with off-peak appliance schedules.

Pillar 02

Tranquilidad Familiar

Single-glance reassurance: doors locked, windows closed, stove off, and vacation mode activity.

Pillar 03

Simplicidad “Plug & Play”

Eliminating technical protocol jargon into an accessible, tactile mobile interface for all ages.


User Personas

From our 13 qualitative interviews, we modeled three distinct personas representing the dominant domestic archetypes and tensions: child security anxiety, off-peak energy scheduling, and sustainability routines.

“Me da miedo que entren a robar a casa o que a mis hijos les pase algo cuando están solos. Siempre reviso que las ventanas estén bien cerradas.”

Functional Needs

Instant reassurance: remote confirmation that windows and doors are securely shut, simulated vacation mode, and emergency protocols.

Non-Functional Constraints

  • Calm, non-alarmist communication tone.
  • Zero technical manual required; kid-friendly.
  • Instant biometric access verification.

“Los dispositivos inteligentes me permiten saber la realidad de mi casa y ahorrar en las horas valle. Pero odio tener una app distinta para cada marca.”

Functional Needs

Real-time kilowatt and cost accumulation tracker, automated off-peak scheduling of heavy appliances, and multi-device telemetry.

Non-Functional Constraints

  • Unified cross-brand device support.
  • Rapid routine configuration under 60 seconds.
  • Clear data visualization without chart clutter.

“Me preocupa la eficiencia energética y transmitirle a mi hijo la importancia de un futuro sostenible. Busco algo plug & play que no me complique.”

Functional Needs

Gentle bedtime routines (dimming corridor lights), notifications for phantom standby power draw, and automated climate shutoff when leaving.

Non-Functional Constraints

  • Zero privacy infringement or personal data sales.
  • Warm, organic, welcoming visual grammar.
  • Tactile card customization on the home screen.

Information Architecture

To eliminate cognitive fatigue, we designed a taxonomy that cleanly distinguishes high-frequency glanceable home status from deeper device configuration. Controls are clustered into 4 core functional domains.

01. Dashboard Glance

Home & Presence Status

Glanceable status widgets: doors/windows closed, current power draw, temperature, and 1-tap panic lock.

02. Domestic Access

Acceso al Hogar

Time-limited digital invitations for cleaning staff or grandparents, biometric entry, and doorbell video.

03. Climate & Energy

Climatización

Zone-by-zone room temperatures, automatic heater shutoff on window open, and appliance scheduling.

04. Family Control

Control Familiar

Screen time limits, hazard locks on ovens/stoves, bedtime dimming routines, and ambient bedroom monitoring.


Paper Wireframes

Before moving into high fidelity in Figma, our team conducted rapid paper wireframing iterations. We explored 8 mobile viewports to validate thumb-zone reachability, test mental models for navigation, and ensure that secondary settings never bury immediate home safety actions.

Prototype & UI

To counter the sterile, clinical feel of industrial smart home software, WAND uses a warm, human-centric design grammar. Warm coral accents (#E84E2D), soft cream cards (#FFF5F2), and relatable illustrations make the technology feel welcoming rather than intrusive.

Family Onboarding

Family Onboarding

Explaining value through daily routines, not technical device specs.

Transparent Security

Transparent Security

Biometric verification, explicit permissions, and local encryption.

Your Home in Hand

Unified cross-brand orchestration accessible with a single tap.

High-Fidelity Interface

Domestic Control, Reimagined.

Every interaction flow in WAND is mapped to reduce anxiety: frictionless family onboarding, clear room-by-room status monitoring, automated off-peak energy scheduling, and non-alarmist child safety alerts.

Reflection

Technology in the domestic sphere must strike a careful balance between control and discretion: it should never demand attention; it should quietly reassure.

By anchoring WAND in 13 field interviews and rigorous affinity mapping, our team avoided the trap of building technology for technology's sake. Every interaction in WAND addresses a concrete anxiety expressed by real parents: keeping children safe, saving money on utility bills, and eliminating digital friction.
