Human-Computer Interaction Communicability Evaluation Method applied to Bioinformatics

Quality measures have different focuses and importance for distinct roles, like developers, maintainers, purchasers and end users. The focus of a quality evaluation may be of internal quality, external quality or quality in use. Quality in use is the quality of the software product from the user's point of view and can be measured by using the software in a specified environment and context. Computer systems must satisfy determined quality criteria to assure some interface characteristics to their users. Several evaluation methods can be applied to different objectives of the quality in use. In the interface interaction evaluation, through Communicability Evaluation Method (CEM), the users can be monitored during the use of the system, some of their utterances can be identified and mapped to specific tags. In Bioinformatics, a challenge for interface development is to provide an integrative and adequate view of a huge and diverse amount of available and accessible biological data. It is difficult to achieve together, interface usability and data expressiveness, especially when the data are heterogeneous and very connected. That is the case of 2Path, a database of metabolic networks of terpenoid biosynthesis. Using evaluation by observation on CEM, we measure the following quality criteria for an interface built for 2Path: usability, user experience, accessibility and communicability. We present here the results obtained and the perspectives of a new interface that aims to meet the post-evaluation requirements fully.
