As gadget gurus line up to hail 2010 as the year of the projector phone, Samsung has used the Mobile World Congress in Barcelona to unveil its Beam model - previously known as the Halo. The Android-based phone's built-in pico projector can throw DVD-quality images of 720p standard onto a wall.

The device also boasts a 3.7-inch AMOLED screen, a 5-megapixel camera and DivX and Xvid playback support. The DLP pico projector is said to cast a six-lumen image and has its own customised interface when blown up.

Because the handset can open Microsoft Powerpoint documents, impromptu meetings among colleagues are made possible, as are photo and/or video-viewing sessions among friends.

Educational users will be further pleased to hear of Samsung's unique implementation that allows the camera's sensor image to be viewed through the projector.

BlackBerry maker Research In Motion also recently revealed details of BlackBerry Presenter, a new feature which will let users of the smartphone stream PowerPoint presentations from their handset to a projector via a wireless connection.

When it becomes available, the connector will also mean speakers can use their handset as a remote control for the projector during presentations.
