To work on interface usability means studying and conceiving interactions between a human being and a product (a mobile phone, a car, a PC and so on).

A usability professional’s occupation is based on user observations “in context”
The interactions between user and system must be designed keeping in mind:
- user profiles and user roles;
- usage context;
- use scenarios.



Our usability service consists of usability evaluation and usability concept. They can precede the user interface design process.
Usability evaluation is a twofold analysis of your interfaces: An expert review and gathering user feedback. This study leads to a prioritized list of requirements.

Usability concept aims at a complete or partial usability redesign of an interface. It allows to establish new interaction principles for navigation, screen structure and so on. The redesign leads to the creation of an interface style guide.
Only field observations allow you to truly understand the reality of your users’ working conditions, their real knowledge and their implicit micro-tasks, including workarounds to bypass a problem.

The observation phase is a necessary filter for all earlier or later user interviews and their results.
These elements serve as a basis for the creation of user profiles and use scenarios, which later in the process will guide usability professionals and interaction designers towards user interface creation.
Usability field is determined by rules and criteria from cognitive psychology developed in usability research laboratories.
We constantly monitor the developments in this domain, because they allow us to optimize your interfaces, make them more intuitive and easier to use.
