Abstract: As an innovative theoretical approach， value sensitive design dialectically views technical design and social context through the interaction between value and technical design. It employs a tripartite methodology， which consists of conceptual， empirical and technical investigations. Throughout the process of technical design， ethical import is emphasized and ethical issues are addressed. Value sensitive design advocates that designers should take full account of the moral feelings and value appeals of technical users and other stakeholders. Despite the obvious practical significance and some advantages， doubts and questions do exist. There is still a long way to go in that its application may be affected by the complex factors of technology.

Key words: technical design, value sensitive design, technological ethics, Batya Friedman
