The close relationship between affective computing technologies and consumer electronics cover many areas. We trust this IEEE Transactions on Affective Computing special section will give readers a comprehensive discussion on various technological challenges associated with consumer electronics, and how a wide range of appliances and services can be supported by applying both existing and emerging technologies. We trust that in the future similar topics on affective computing for consumer electronics will be covered in future issues of the IEEE Transactions on Affective Computing, as laboratory works are being prototyped for eventual commercial realizations. In this special section, three papers are very carefully selected such that each targets very different areas for both business and consumers.
