Usability testing as a systematic tool for product performance valuation during design process of an ischial support

This study aims to show the particular features of the usability evaluation process, with an emphasis on the analysis models and the way that tests were conducted using protocols and instruments for recording information. The paper also aims to show how the participation of users can be regarded as a substantial tool, not only in achieving a more accurate final result, but also the manner in which the functional analysis process is facilitated. The completion of this project has shown that a detailed analysis of usability at different stages of the design process is a fundamental tool in determining which objects in a public space adapt adequately to their environment and to their potential users.
