Progress of the project

The project started January 11th, 2015.

Week 1 (January 11th - January 17th)

Week 4 (February 1st - February 7th)

Design patterns

• Model-View-Controller (GoF) : This pattern is used to separate application's concerns. Our project is Web oriented program
• Singleton (GoF) : Ensure a class has only one instance, and provide a global point of access to it.

Example : a teacher is the only one who can launch slides

• Visitor (GoF) : Represent an operation to be performed on the elements of an object structure. Visitor lets you define a new operation without changing the classes of the elements on which it operates.

Example : students can edit the subtitles

• State (GoF) : Allow an object to alter its behavior when its internal state changes. The object will appear to change its class.

Example : Microphone detection

• Service Contract - Concurrent Contracts (SOA) : http://soapatterns.org/design_patterns/concurrent_contracts

Project work

Solving critical problems : the API is not working with ambient noise. When we are talking directly to the microphone the API is working fine.

Tests :

• Fast talking : Dead after 1 minute
• Slow talking (with interruptions) with music arround : Dead after 2 minutes
• Slow talking : Dead after 2 minutes

Meeting with Jérôme to have new directions after a quick demo of the app.

Week 6 (February 15th - February 21st)
