AniCode: authoring coded artifacts for network-free personalized animations

摘要

Time-based media are used in applications ranging from demonstrating the operation of home appliances to explaining new scientific discoveries. However, creating effective time-based media is challenging. We introduce a new framework for authoring and consuming time-based media. An author encodes an animation in a printed code and affixes the code to an object. A consumer captures an image of the object through a mobile application, and the image together with the code is used to generate a video on their local device. Our system is designed to be low cost and easy to use. By not requiring an Internet connection to deliver the animation, the framework enhances privacy of the communication. By requiring the user to have a direct line-of-sight view of the object, the framework provides personalized animations that only decode in the intended context. Animation schemes in the system include 2D and 3D geometric transformations, color transformation, and annotation. We demonstrate the new framework with sample applications from a wide range of domains. We evaluate the ease of use and effectiveness of our system with a user study.
