Value sensitive design (VSD) is a theoretically grounded approach to the design of technology that accounts for human values in a principled and comprehensive manner.  VOD addresses design issues dans le fields of information systems design and human-computer interaction by Emphasizing the ethical values of Direct and indirect stakeholders . It was developed by Batya Friedman and Peter Kahn at the University of Washington in the late 1980s and early 1990s. This approach takes human values into the whole process.  Designs are developed using a tripartite investigation consisting of three phases: conceptual, empirical and technological.
Privacy by Design is an example of VSD that is concerned with respecting the privacy of end users of (IT) systems.
VSD uses an iterative design process that involves three types of investigations: conceptual, empirical and technical. Conceptual investigations in the context of the use of technology. Empirical investigations are qualitative or quantitative design research studies used to inform the designers ‘understanding of the users’ values, needs, and practices. This paper presents the results of the study of the conceptual and empirical investigations of the concept of the social sciences.
