Description

Over the past four decades, the prophecy from computer pundits and prognosticators pointed that looming arrival of the paperless office era was coming. However, forty years later, physical paper documents are still playing a significant role due to the ease of use, superior readability, and availability. However, the drawbacks of paper sheets are hard to modify and retrieve, and environmental unfriendly. Camera-based recognition and detection devices have been proposed to augment paper document with digital information to overcome the drawbacks. However, there are still some limitations exist in these systems. Different from previous approaches, this study presents a novel, spatially aware, mobile system (called Ultrasonic PhoneLens) which adopts 2-Dimensional dynamic image presentation and ultrasonic sound positioning technique. In this study, an asynchronous network is developed to smooth the movement of a mobile device within a large workplace. The results indicate that our application is robust and multifunctional.
