01 · The Problem
Modern homes often contain many separate smart devices, applications, sensors, and control systems. While each device may be useful individually, interacting with multiple interfaces can become inconvenient and difficult.
This problem becomes more significant for elderly users, children, or people who are less comfortable with digital interfaces. A useful home assistant should not require users to remember which application controls which device.
MIMI began from the idea that technology should adapt to people rather than forcing people to adapt to technology.
02 · The Idea
The goal was to build a home assistant that could interact with people naturally through voice while remaining connected to the physical environment through sensors, cameras, and smart devices.
Instead of creating a single-purpose gadget, MIMI gradually evolved into a modular platform that connects voice interaction, AI services, environmental sensing, computer vision, home automation, media, and a smart mirror interface.

07 · Engineering Challenges
Engineering Decisions
Functions are separated into services so individual components can be improved without rebuilding the whole system.
Processing and control are kept close to the Raspberry Pi where practical.
MIMI is tested in an actual household rather than only under controlled conditions.
08 · Testing & Iteration
The project has evolved through repeated cycles of testing and refinement. Voice sensitivity, device reliability, information display, media playback, sensor monitoring, and system stability have all been improved through practical use.
09 · What I Learned
A complete engineering system requires more than making individual components work. Hardware, software, communication, reliability, resource limits, and user interaction must all work together.
MIMI taught me to break complex problems into modules, test assumptions through prototypes, diagnose failures systematically, and design for reliability rather than functionality alone.
10 · Social Impact
One of MIMI's long-term motivations is to explore how intelligent home technology can become more accessible to elderly users, children, and people who may find conventional digital interfaces difficult to use.
