Explore a conference talk that introduces Montage, an innovative video prototyping system designed to streamline the creation of interaction prototypes. Learn how this tool combines video with digital animated sketches to reduce re-shooting and increase re-usability in the design process. Discover how Montage utilizes chroma keying to separate the prototyped interface from its context, allowing designers to independently reuse or modify elements. Gain insights into the system's ability to enhance video prototyping, encourage exploration of various use contexts, and support different interaction styles. Delve into topics such as prototyping speed, dynamic prototyping, low-budget techniques, and the Octopus Technique. Examine practical examples, including proximity interaction and augmented reality applications, to understand Montage's potential in improving the design workflow.
