Social TV EPG Interaction Design for Multi-screen Environment

Along with the development of Web 2.0, Internet users are gradually evolving from passive recipients of content to content creators. Considering recent technological advances and improved service designs, television (TV) content and its interactive methods have drastically changed. Moreover, various information devices ranging from wide-screen TVs in the living room to individual laptops or mobile phones have spread throughout the TV-watching environment. However, the increasing number of TV channels has given users a wider range of TV programs to choose from. Based on these issues, this paper proposes a social TV Electronic Programming Guide (EPG) interaction design under scenarios wherein users interact with a multi-screen TV, which aims at offering strengthened EPG services such as EPG navigation, EPG recommendation, and EPG searching, based on users´ virtual social relationships.
