Sony Corp. on Wednesday announced the launch of head mounted display “personal 3D viewer” HMZ-T1, a device that offers a new style for viewing both 2D and 3D content. The HMZ-T1 allows to simply slip the device onto one's head to experience the movie theater-like virtual screen (equivalent to a 750") expand before the eyes. Unfortunately, the product does not support full-HD resolution and its availability time and price are unknown.


The head mounted display “personal 3D viewer” HMZ-T1 is equipped with two newly-developed 0.7" (18mm) high-definition OLED panels (1280*720), which have been realized through Sony’s expertise in both OLED display and semiconductor silicon drive technologies. The device adopts the "dual panel 3D method" which consists of separate panels for the left and right eye in order to realize high-definition stereoscopic 3D picture. The HMZ-T1 provides wide horizontal viewing angle of 45° by incorporating an optical lens that thoroughly suppresses unwanted elements such as aberration and distortion. Viewers can enjoy watching video on a movie theater-like big-screen (750" virtual screen, virtual viewing distance approx. 20m), according to the manufacturer.


Sony's HMZ-T1 incorporates Sony’s surround signal processing technology "5.1-channel virtual surround technology", which was developed especially for headphones. Virtualphones Technology (VPT) creates a sound field that naturally reproduces the sound to make it seem as though the sound source is emanating from speakers placed all around the viewer (including front and back). The viewer can enjoy sound equivalent to a maximum 5.1 multi-channel audio, thus further enhancing the spatial effects of 3D.

The HMZ-T1 comes with a processor unit that is used to connect to various sources, such as Blu-ray 3D players. The processor unit is equipped with one HDMI output and another for through output. The built-in HDMI output switcher enables both the head mounted display and a television to be connected to the processor unit at any given time, thereby allowing the user to switch between devices for their desired output destination. The processor unit and the HMD are connected together with a single cable, which integrates the audio and video signals with the power source.

The device’s control key (located behind the front) is used to control the volume and basic operations (such as playback, pause, fast forward, rewind, previous chapter, next chapter) of any connected devices with HDMI CEC control function. Settings for the picture quality and audio quality can also be performed via menu screen.

Unfortunately, it is unclear when the device becomes available and at what price-point.

Sony asks children (age 15 and younger) to refrain from using this product.
