Usability lab: the UsabiliLAB
The usability lab is called UsabiliLAB. The UsabiliLAB is dedicated to research, in a formation area and the technology transfer.
The UsabiliLAB offers its services for the development and research on user center information systems according to the ease of use and its adaptation to the user limitations. Every executed procedure use the model of user centered process to get this ease of use (called usability) and to break the user’s barriers (called accessibility) in the information systems
The Usabililab provide experts with the best resources to carry out user test and evaluations of interfaces.
The usability contributes an economical benefit to the developer companies and:
- More efficiency: the user may finish a specific task spending less time.
- Easy learning: the user can assume how an object works observing it.
- More user satisfaction.
We evaluate the usability of an interactive system using the following techniques:
- Eye Tracking
- User Test and “Common Industry Format” (CIF) reports for the results
- Heuristic evaluations
- Supervised sessions
- Cognitive Walkthroughs
The accessibility is a legal right and a social need. Moreover, the accessibility reaches an economical benefit to the organizations and companies because they can get new clients and they can open new markets.
We evaluate the accessibility of an interactive system according to the W3C guidelines.
According to the usability and accessibility results, we propose the needed reengineering actions to improve the interactive system. To guarantee this, we follow the User Centered Design (UCD) methodology as a methodology where the user is considered in the whole design process.
User Centered Design (UCD)
The interactive system design implies the creation of a design where the user is the focus of attention and the implementation of the system functionalities is carried out according to their features.
The UCD model is the MPIu+a (the acronym of Model of Usability and accessibility engineering process) who assumes the fulfillment of one of the priority research lines that the GRIHO member carried out. So, we offer the best services using the following techniques:
- Requirement analysis
- Conceptual model
- Card sorting
- Task analysis
- Interface design
