Visual search aims to find information based on visual features of objects, and it is extremely useful when specific keywords for describing an object are unknown. Visual search has been considered as one of the most exciting trends in e-commerce.  CircleBuy  is a second screen application that leverages visual search to allow users to select pieces of furniture in a video and to receive similar product recommendations. In addition, our application attempts to support users in making purchase decisions by showing a 3D model of the piece of furniture that helps them to explore the product in detail. Products can furthermore be shared on television to discuss them with friends and family. This paper presents the concepts behind  CircleBuy , its engineering and implementation aspects, and its evaluation. The concept was evaluated with 22 subjects in a simulated home environment. The results demonstrate the meaningfulness of the concept and offer insight into the utility and usability of the design of such a visual search based application.
