Websigns: hyperlinking physical locations to the Web

HP researchers are developing handheld devices that combine wireless technology and ubiquitous computing to provide a transparent linkage between physical entities in the environment and resources available on the Web. First-generation mobile computing technologies typically use protocols such as WAP and i-mode to let PDAs, smart phones, and other wireless devices with Web browsers access the Internet, thereby freeing users from the shackles of their desktops. We believe, in addition, users would benefit from having access to devices that combine the advantages of wireless technology and ubiquitous computing to provide a transparent linkage between the physical world around them and the resources available on the Web. We are developing devices that augment users' reality with Web services related to the physical objects they see
