If you are already accustomed to Vive or Touch controllers, then the handle of Daydream View is really strange to start using. Because it only supports orientational changes in space, we must keep the arm and wrist in the same direction. But once used to such a use, its response speed and accuracy enough to deal with a variety of Daydream interface menus, keyboards or handle some special simple games. Once again, this experience is definitely not what Cardboard can provide, but also more vivid and complex than a simple 360-degree passive video.

View will not only include Daydream View headsets, but more vendors will also launch their own devices that meet Google's reference standards in the coming months. Google has already put forward the hardware standard requirement to Daydream View platform, at the same time, the manufacturer can also adjust the controller and design details under the standard. In addition, manufacturers can also use other different materials and add extra features such as adding high quality headphones or adding power extensions like Mophie.

"We don't want Daydream View to look too distant, but now it looks very simple and elegant. In the future our partners will promote the development of the entire platform by adding more new features." Narkter said.

Although Google's compatibility with the Daydream platform was vague in the first half of this year, it has now been confirmed that any Daydream device is compatible with Daydream-standard smartphones. With the development of time, Daydream smart phones of different eras will have different changes, and in the future Google will adjust the compatibility between Daydream View headsets and Daydream View smartphones of different eras, the balance between generations, and With the cooperation of other VR products, it is still premature to feed the conclusions.

Daydream View's future development is entirely based on whether Google can provide a convincing experience. The easier the user is to use, the easier it is to use, and the lower the threshold for use, the easier it will be to conquer the user and make the user worth all the investment. Daydream View currently sees that Google has completed its first step. (Author: Adi Robertson compiled: Human)

Printer Adapter

Printer Adapter means the charger of printer; the most printers used in the market are HP, EPSON, CANON and BROTHER brands, yidashun produces ac adapter for all these brands of printers. The output voltage of these printer ac adapters are normally 12V, 16V, 22V, 24V, 30V, 32V and so on, the common dc plugs are 3 hole (Flat) and 3 pin (Round).

The popular hp printer adapters are double output 32V 1.1A/ 16V 1.6A, 16V 625mA / 32V 940mA, 12V 250mA /32V 1094mA, and single output 30V 333mA, 32V 2000mA, 32V 2500mA, 22V 455mA and 32V 625mA, the dc plug of all these models are 3 hole (Flat). The popular EPSON printer charger is 24V 2A output with 3 pin (round) dc plug.
