2. Non Functional Requirement - hguerra/InteractiveDataVisualization GitHub Wiki

The characteristics describing the quality and usability of the tool are defined in Table 1, which represent the constraints for the service system developed. As an example, was defined by the functional requirements that the system has six possible gestural inputs, this set of entries creates the restriction that the system must recognize all defined body movements.

Attribute	Description	Requirement
Gesture Recognition	System should recognize at least 6 movements.	Product Requirement
Response Time	When detecting a movement, the system must update the map in less than 1 second.	Product Requirement
Interface Type	The tool control will be gestual.	Product Requirement
Fault Tolerance	The recognition algorithm must recognize at least 70% of the movements performed.	Product Requirement
Operational System	Microsoft Windows 7	Product Requirement
Usability	The user must be able to operate after 10 minutes of training.	Product Requirement
Implementation	The system must be developed in the Java programming language.	Organizational requirement
Design Patterns	Using object-oriented programming and Model-View-Controller design.	Organizational requirement
Legal Rights	The system must be open source.	External requirement
