Overview

Which global features ?

• Handle a network of "interactors"  : Sensors and Actuators in a house

• Offers to the user the possibility to easily bind a sensor detection to an action on an Actuator via a web interface "everyware"

• Generic : adding a type of  interactor is easy for the developer

Architecture

Event management

Interactors class diagram

Readings

• Messages from the sensors are received by the main server.

• The message contains a query to register an interactor, or a reading. A new interactor is then registered in the database, or the reading is stored by calling the read_message method of the interactor.

• When storing a reading, check if the value should trigger an event.

Readings

Binding management

Web interface for the user

• Accessible everywhere

• The user is free to chose which event is linked to which callback ( demo )

• Visualization of the house state ( temperature diagrams...) ( display not implemented )

• Adding/deleting interactors (demo)

Demo

What is implemented

• Registering interactors, binding events to callbacks
• Display them in the web interface
• LeapMotion Sensor that send formatted data to the main server
• Music player that uses spotify to play music, and can control music volume of the computer
• A python script to manually send messages to the web server
• A lamp actuator, and PresenceDetection sensor

Futur work

• Implements the displays of all the sensors and triggers
• HeartBeat protocol to keep an updated list of the interactors state
• Use the readings to create a context, make guesses to interact automatically with the users motion
• securely identify the interactors by exchanging keys to prevent unrelated sensors to send data to the main server
