PaperChains: Dynamic Sketch+Voice Annotations

In this paper we present a novel interface for collaborative creation of evolving audio-visual documents. PaperChains allows users to sketch on paper and then augment with digital audio, allowing both the physical and digital objects to evolve simultaneously over time. The technique we have developed focuses on affordability and accessibility in its design, using standard cameraphones and telephone connections, which allow it to be used in regions where literacy, technological ex-perience and data connections cannot necessarily be taken for granted. The main use-case that we focus on in this paper is for collaborative storytelling, an area which has been well studied and previously proven to be of value in resource constrained environments. To investigate the relevance of the approach in these contexts, we undertook two usability evaluations in India and South Africa. Results from these investigations indicate users ’ ability to both create and interpret stories using the software, as well as demonstrating high overall usability and enjoyment. We end with a discussion of the implications of our design and opportunities for use in other contexts. Author Keywords Sketching; audio; photographs; cameraphones

Designing interactive newsprint

The possibility of linking paper to digital information is enhanced by recent developments in printed electronics. In this article we report the design and evaluation of a local newspaper augmented with capacitive touch regions and an embedded Bluetooth chip working with an adjunct device. These allowed the interactive playback of associated audio and the registration of manual voting actions on the web. Design conventions inherited from paper and the web were explored by showing four different versions of an interactive newspaper to 16 community residents. The diverse responses of residents are described, outlining the potential of the approach for local journalism and recommendations for the design of interactive newsprint
