摘 要：While mobile phones have penetrated deep into tier 2 and 3 cities in India and similar emerging economies, adoption of mobile web content and web services is likely to require the creation of large numbers of relevant applications and services with usable interfaces and interaction paradigms. This paper describes PaperWeb, our effort to enable mobile phone users to use the web for day to day transactions such as paying bills, buying tickets, or fixing appointments, using familiar objects such as paper artifacts. The PaperWeb system addresses two aspects: (i) creation of useful PaperWeb interactions - without programming - by moderately tech-savvy users, and (ii) the use of these interactions by tech-naive users. We describe a user study that motivated PaperWeb, and the design of the PaperWeb system and its technology components. We conclude the paper with a discussion of what has been achieved to date and future directions.
