During the TechFest tradeshow, Microsoft displayed all of its new technologies in hardware, primarily focused on enhancing the user experience. More than 800 researchers have been working at these numerous projects, offering a vast idea about how computing will look like in the near future.

Steve Ballmer, CEO at Microsoft, was there to cheer up investors, stressing that researches in the computing technology have crucial importance in the days of the economic recession. Strangely, though, it seems that Ballmer’s optimism about the 40 projects highlighted didn’t manage to help Microsoft commercially, as yesterday, the company’s stocks declined by a few cents.

While the new devices and technologies were available for, journalists and other partner companies on Tuesday, the Redmond giant opened its booth to the researchers today. TechFest aims to gather engineers at many tech companies to share their new projects, but the exhibition has become very popular for the past few years.

Among the most important products, the most popular projects were a portable device that displays sticky notes and a new technology that lets developers put ads next to images on websites. Microsoft also highlighted a data center system powered by 100 Intel Atom processors, as a low-cost alternative to the current offerings.

The English division of Microsoft revealed an innovative device, called Family Archive. David Kirk, a representative at Microsoft’s lab in Cambridge, stated that the new device could store and display a great variety of media content, such as pictures, videos and memos. The device uses an advanced screen interface with multitouch capabilities.

The company also displayed a wireless remote control that implements motion sensors, a similar concept with Nintendo’s WiiMote. Other devices include a pencil that recognizes “air writing” and several updates and devices engineered to run with Microsoft Surface.
