NTT Develops "Virtual Smartphone" Switchable Dual System

NTT Develops "Virtual Smartphone" Switchable Dual System NTT developed a "virtual smart phone" and demonstrated it at the "NTT R&D Forum 2011" (NTT Musashino Research and Development Center) held from February 22 to 23, 2011. According to the R&D center, this is a technology for manufacturing smart phones using thin-client technology. From a technical perspective, it is also possible to use a terminal to switch to “Android terminal” and “iPhone” at the right time.

The prototype terminal developed this time has installed its own thin client software in the Android terminal. The thin client refers to the OS and the software running on it all running on the server side, and only send the screen information to the technology and system displayed on the terminal.

Using this developed system, the Android OS runs on the cloud server and sends only the screen information to the terminal. Since the terminal itself does not perform heavy operations, the advantage is that the ease of use of the terminal is not easily affected by processor performance and memory size. According to the NTT Musashino Research and Development Center, although communication is frequent, only differential information is sent from the server to the terminal in the screen data, so it is possible to reduce the power consumption of the terminal.

This is only to reduce the size of the original thin client terminal, but this time on the terminal side has retained the smart phone touch sensor, position sensor and GPS sensor functions. The information detected by these sensors is sent to the server side in real time, so it is as easy as the original smartphone to operate the screen and use location information.

In addition, a virtual memory card function called "Virtual SD" is also installed on the terminal. According to reports, when photographing with a terminal, data is transferred to the server in real time, but the user can use the photo data as if it were stored in a terminal SD card.

The R&D center pointed out that since it is technically possible to personalize the OS running on the server, it is also possible to switch a terminal from an Android terminal to an iPhone terminal or a Windows Mobile terminal according to mood. However, "at present, due to the licensing relationship, this is not yet installed."
