As far as web search tools go, few have generated as much hype as Wolfram Alpha. The service, which bills itself as a "computational knowledge engine," differs from search engines such as Google, in that it does not return lists of web pages. Rather, Wolfram Alpha attempts to calculate answers to user queries. For example, a query of "los angeles county median household income" will return the result "$43,518."
Ocutag, a division of Ricoh Innovations, aims to help apps deliver content to users taking photos. Their aim is to herald a new model of retail. App designers upload images and tag them with information. When users snap pics of the same thing in reality, information can be delivered through the app, such as that appearing in the graphic of the scarf below: where to buy it, details about it, local stores that carry it. What information is delivered is up to the company with the app. The company provides the Ocutag API for integration.
