For wireless data transmission, Sony employed Bluetooth technology. A smartphone can be connected to the HMD and used as a remote. Also, the company is considering a Bluetooth-connected dedicated remote. It will not add wireless LAN capability to the HMD at first because it requires a large amount of power. The HMD can be controlled not only by a remote but by voice. But it will not support gesture inputs.

At first, the HMD will probably be able to display only SD (standard-definition) video. Though the prototype displayed monochrome (green) video, the product will be able to display full-color video using red and blue colors in addition to the green color. The display device and light source of the HMD will be an LCD panel and LEDs, respectively. And it will come with a camera that takes images of the real world.

Though the color of the prototype was white, Sony is considering releasing the product in two colors: white and black. Furthermore, one of the glasses might become detachable so that the HMD can also be used as a monocular type.

Head-tracking function added to HMD equipped with OLED panel

In the booth, Sony also showed an HMD product that uses an OLED panel as a display device. It was not an optical see-through HMD.

Sony attached a motion sensor module to the HMD to realize a "head-tracking function," which detects the movements of the user's head, enabling to switch videos by moving the head. Though a video of town streets was displayed in the booth, this function can probably be used for gaming, too.
