DeepShot syncs running apps between computer, phone
Getting those Google Maps directions you're viewing on your PC onto your smartphone might soon be as easy as pointing the phone at the screen.
Tsung-Hsiang Chang, a graduate student at MIT's Computer Science and Artificial Intelligence Laboratory, and Yang Li, a Google employee, have developed a system that makes it much easier to transfer certain Web-based computing tasks between devices. To do this, one simply takes a photo of the computer screen that's showing the task. The phone then automatically opens up the corresponding application on the mobile device--at the corresponding stage of the task.
The same process can also work in reverse, moving data from the phone to a computer.
The system, called DeepShot, relies on the fact that many Web applications use a standard format, called the uniform resource identifier (URI), to describe their current states. A typical example of this is the link provided by Google Maps that transfers the exact current location or driving directions to another browser on another computer.
This link consists of a long string of symbols that contain URI-related information such as the addresses of the starting and ending points and codes that indicate their geographical coordinates and the approximate size of the map window. Though URIs are a common feature of many Web applications, the data contained in a URI can vary greatly and is sometimes harder to extract than in the case of Google Maps.… Read more
