Microsoft's largely mysterious Menlo project has been caught running through a newly discovered research paper (PDF). A 4.1-inch, capacitive touch prototype said to be Menlo, although also identified as using Windows Embedded CE 6.0 R2, has been used to show an example of an app codenamed Greenfield that would use an accelerometer, a barometer and more to provide in-building navigation. What's special about Menlo isn't detailed, but the app would give directions involving stairs and elevators rather than just 2D positioning.
