Microsoft has been revealing a lot of cool research projects lately. One of the latest ones is "Menlo", a project that focuses on activity-based navigation on mobile devices. One of the applications highlighted in the disclosed research paper illustrates how "Menlo" could be used to find a parked car with a Silverlight-based prototype application codenamed "Greenfield".
"Menlo is a prototype mobile device with a capacitive touch screen (4.1‖ diagonal, 800x480) running Microsoft Windows Embedded CE 6.0 R2 which incorporates a Bosch BMA150 3-axis accelerometer and Bosch BMP085 digital pressure sensor (barometer)," the paper suggests.
While it's unlikely the "Menlo" project will ever become publicly available, it seems the device has been designed with a focus on testing a new Silverlight-based prototype application called "Greenfield", which allows users to find a parked car.
"To explore activity-based navigation we designed Greenfield, an application that provides an activity-based trail to a parked car," the description within the paper reads.
