As expected, Sony announced their own virtual reality headset at GDC last night. From the PlayStation Blog:

Our current prototype for Project Morpheus features a head mounted display with 1080p resolution and a 90 degree field of view. Accelerometer and gyroscope sensors built into the head mounted unit as well as PlayStation Camera accurately tracks head orientation and movement, so as your head rotates, the image of the virtual world rotates intuitively in real-time. Project Morpheus also features our new 3D audio technology that re-creates stereoscopic sounds in all directions and changes in real-time depending on your head orientation. In addition to PlayStation Camera, Project Morpheus works with DUALSHOCK 4 Wireless Controller and PlayStation Move to deliver an easy-to-use, plug-and-play VR experience.

From the patent abstract:

A block tool, which can be assembled by a user, is configured with multiple types of blocks and is shot by a camera for capturing a still image or a moving image. The position coordinates of a marker of the square-pillar block in a three-dimensional space are obtained by image recognition. Also, a connecting position and the type of each block, a gradient vector of the square-pillar block, an angle between two blocks constituting the square-pillar block, and the respective blocks' lengths are obtained so as to derive the shape, posture, and position of the block tool, and corresponding information processing is then performed.

PlayStation Now is a new streaming service that will allow Sony consumers to stream PS games on a variety of devices including tablets and smartphones: "In addition to PlayStation platforms, most 2014 U.S. models of Sony's BRAVIA® TV*2 lineup will support PS Now. Eventually the service will expand beyond PlayStation platforms and Sony devices, allowing users to stream PlayStation games on numerous other Internet-connected devices." The first two games slotted to be available via the service are The Last of Us and Beyond: Two Souls. Get more details from the video above.
