Smart Home

Interaction design

SCENARIO:
A 35yo user lives in a single-family smart home.
The builder installed a computer with a screen embedded into a wall next to the entrance door, from there he can control all house features with a 3D interface.
Using such 3D model of th
e house, the user, among other things, can view every fixture installed in the house, including lighting fixtures. The builder also sell lightining fixtures and replacement parts.

GOAL:
The goal of this project is to design an intelligent lighting monitoring and management system, which enables users to control and set up the lighting fixture, get notifications and view a timeline of daily home activity. 

USER RESEARCH 
Following the indications of the brief, I created my reference persona. I based my design and structure decisions on this persona.
USER JOURNEY EXTRACT
h. 7 pm
Andrew comes back home from work and he leaves the car in front of the garage.
The driveway lights are already on thanks to a twilight switch and a previous setting from the application.
He enters at home and accesses to Control Panel. Janet, the vocal assistant, welcomes him.
Andrew turns on and manages the lights in the living room. Turning on those lights, the music starts.

h. 7.30 pm
Andrew takes a shower.  A motion sensor detects his presence in the bathroom and automatically turns the lights on.

h. 8 pm
Andrew goes out for dinner and turns all the lights from the Control Panel, through "Leaving home" mode.
Driveway lights will remain on till dawn.
CONTROL PANEL'S FEATURES
- Connection settings
- Switch ON/OFF the light with intensity control
- Set color by temperature
- Set Automatic schedule for light management
- Shop: order lightbulbs
- Set interactions with other sources (physical switch, smartphone and app, even from other persons)

Additional features:
- Special effects (dawn, sunset, fire, party, ecc..)
- Alert and notifications
TECHNOLOGIES
- Touch screen
- Artificial Intelligence: Janet, the vocal assistant, with a human tone and positive emotions, the user can ask her to do everything the application could do and manage every device.
- Twilight switch for patio and terrasses
- Motion sensors in the house: the user can decide to abilitate or not these sensors to let them switching on and off the lights at the passage in every room
SKETCHES & HIGH-FIDELITY WIREFRAMING
After gathering all the information I needed, I started writing down the first wireframes that allowed me to brainstorm myself with some features and user flows. 
The first problem encountered was how Andrew could manage groups of lights, regardless of the room he was in.
I therefore opted to use some "Modes": four by default (leaving home, coming home, good night and good morning) and the possibility to modify and/or add them.

The second concerned the fact of being able to select more than one light inside the room and apply the same effects to all the selected ones.
My solution: when the user is on room's view, he can tap each single lights to manage them separately, or tap and hold the first light and then tap the others he wants to manage together. In this way the side menu will apply features to the selected lights. 
LAYOUT
The final layout includes the interactions required by the Brief.
In particular in the first screen we notice well organized elements, with a sort of "header" where the user can find a personal area, informations on today's weather and date, and icons for notifications and for Janet, the voice assistant.

Some "Modes" give the user the possibility to manage some groups of lights, all together. I imagined that "Leaving home" would turn off all the lights, while "Coming home" would switch on some lights the user thinks to use in that moment. 

As regards the 3D model, tapping on the bulb icon, the user can switch on all the lights in that room. While tapping on the name he can enter the room. 

Inside the room (4th screen), there are some "pin" on the lights and I imagined that the user can manage one light (tapping on the light) or more lights together (tap and hold to starting selection of lights). 
Light(s) management is possible from the side menu.
