SmartMirror

Motion controlled SmartMirror showing time and temperature in background with the possibility of adding any widget to the menu. The camera is behind the two-way mirror to get the best possible look. The screen and camera are managed by a raspberry pi. The motion is managed by a server running in python with OpenCV, the server web is in NodeJS.

Capacities

Recognition of gestures : palm, thumbs up/down, slide up/down/right/left
Time and outside temperature
Widgets :
- Photo : take a photo and upload it to Dropbox
- Map : display local Google Map
- Cinema : movie time of local theater
- DoodleJump : play the game (hard with the latency)
- News : show international news

Debugging

The motion server can't recognize gestures on a new environment : lights, hand colors... affect the process, that's why by launching the test.py file and tweak the HSV min/max values and others configs properly you can set it up for your home. To begin the tracking make an open palm like shown in the picture below.

Dependencies

Software :
- OpenCV 2.x
- Python 3.x
- NodeJS
Hardware :
- Two Way Mirror
- Raspberry pi
- Camera (I'm using the NoIR but any camera should do)
- LED Monitor (Preferably that cover the whole surface of your two way mirror)

Building

Web server :
- npm install
- node server.js
- go to http://localhost:3000
Motion server :
- Install OpenCV 2.x and cv2 wrapper for python (should be in the opencv package)
- pip install numpy
- pip install tornado
- python test.py for debug infos or python main.py for silent process
- config.py for the tracking settings
  - To use the Pi Camera set piCamera to true and install the package picamera pip install "picamera[array]"

Notes

The motion server was made in python to learn the language, but it should have been made in C/C++ to gain execution speed and flowness in the gestures recognitions. Also, python environment kinda sucks at the moment, the difficulty to set it up for python3 + opencv2 + windows and then linux was exhausting, I don't recommend.
