Camera phones are the pioneers for convergent networked media devices. As such, new practices are being born from eased capabilities of mobile digital media sharing. Furthermore, new opportunities are created through the collaboration of existing realms into entirely new ones. Focusing on the intersection of social networking, gaming, and media sharing we believe that new uses for media are possible which incent users to play and have fun, while at the same time ease media sharing and promote reuse. Using simple design structures, users are able to interact easily with both the device world and the real one. As well, by providing flexible frameworks to capture and engage with their worlds, playing with media becomes possible.

Current mechanisms for authenticating communication between devices that share no prior context are inconvenient for ordinary users, without the assistance of a trusted authority. We present and analyze seeing-is-believing, a system that utilizes 2D barcodes and camera-telephones to implement a visual channel for authentication and demonstrative identification of devices. We apply this visual channel to several problems in computer security, including authenticated key exchange between devices that share no prior context, establishment of a trusted path for configuration of a TCG-compliant computing platform, and secure device configuration in the context of a smart home.

Browsing the Web with screen readers can be difficult and frustrating. Web pages often contain inaccessible content that is expressed only visually or that can be accessed only with the mouse. Screen-reader users must also contend with usability challenges encountered when the reading content is designed with built-in assumptions of how it will be accessed--generally by a sighted person on a standard display. Far from passive consumers of content who simply accept web content as accessible or not, many screen-reader users ...

Mobile vision services have recently been proposed for the support of urban nomadic users. While camera phones with image based recognition of urban objects provide intuitive interfaces for the exploration of urban space and mobile work, similar methodology can be applied to vision in mobile robots and autonomous aerial vehicles. A major issue for the performance of the service -
