Personalized Enrichment of Video Through a Crossmedia Environment

Crossmedia systems have been gaining space due to their flexibility and capability to deal with a diversity of contexts. The success of these systems resides, mainly, in their capacity to provide flexible solutions to the user interaction through different devices, especially if each device is used to perform what it is most suited for, from the user experience perspective. This paper briefly addresses the challenges faced when designing Crossmedia systems capable of generating personalized information that is added to the video. To illustrate our research, we designed a system, which evolved from previous versions, referred to as eiTV, which generates personalized web-based content that provides additional information on users’ selected topics of interest, while watching a specific news video, such as a documentary or a series. The web-based content may be generated, accessed, personalized, shared and (immediately or later) viewed through iTV, PC or mobile devices, depending on the users’ needs. The paper main contribution is the interaction model designed to support the ‘create’ functionality (which allows to choose the topics of interest) in the news videos, supporting iTV, PC and mobile. We created high-fidelity prototypes of the eiTV system, which were evaluated with the participation of 30 elements, with age range ranging from 20 to 55 years old. The achieved results are presented and discussed.
