Hawaii is a Microsoft research projects which enables researchers & students to develop cloud based mobile applications for windows phone 7. It provides the tools, services etc to enable to develop variety of applications.

The following cloud services are offered:

  • Optical Character Recognition(OCR) : This basically includes the identification of text from captured image which is sent to server & in return the server responds with the text as written on the image. A basic example application that could be thought using OCR is business card reader etc.
  • Speech To Text conversion(STT) : As the name suggests, speech to text conversion involves sending the speech data to server & in response we get the text as identified by it. A basic application example could involve voice command based functioning of features in mobile.
  • Relay Services : Provides a relay point in the cloud that mobile applications can use to communicate. It provides an endpoint naming scheme and buffering for messages that are sent between endpoints. It also allows for messages to be multicast to multiple endpoints.
