rtmyers writes "A really simple yet radical idea: break web pages down into sentences, and then have the browser walk through sentences and do useful sentence-level things. This is the paradigm shift behind the product called Infowalker, which unfortunately is implemented as an IE toolbar, but would be fabulous as a feature built into Mozilla or Opera. Currently implemented features include sentence-level interfaces for TTS, translation, large-type display, and the funkiest of all, dynamic display of an image pulled off the web based on keywords extracted from each sentence -- hey, turn all your web pages into slide shows today! Then there's the feature to show an Amazon product related to the sentence you're reading -- which presumably is the revenue model behind the product, but turns out to also be surprisingly useful. This might not be for everyone, but it could just be the first real change in the browsing model since the earliest browsers starting throwing text up on the screen more than a decade ago. And apparently, Infowalker's architecture allows for pluggable third-party sentence-level "behaviors", with the potential for the development of a whole ecosystem of sentence-level functionality in browsers. And it seems Infowalker can also be controlled by strategically placed custom CSS tags within the HTML, raising the possibility of a new class of web pages especially tuned for this sentence-based approach."
