Demos
Demonstrations provide researchers and practitioners with an exciting and interactive opportunity to present their systems, artifacts and/or research prototypes, either at a regular session or at the technical exhibition. In any case, it is required to avoid a commercial format, even if the demo consists of presenting a business product or service. Instead, the presentation should focus on technical aspects.
Any written support materials may be distributed locally but not published in the proceedings. Authors who already present a paper at the conference may apply for a demonstration, to complement but not to replace their paper presentation. Demonstrations can also be made by sponsor companies or as a mixed initiative involving researchers and industrial partners.
Demonstrations are based on an informal setting that encourages presenters and participants to engage in discussions about the presented work. This is an opportunity for the participants to disseminate practical results of their research and to network with other applied researchers or business partners.
Concerning the format of the demo, we can accommodate it either as a demonstration in a booth (physical area of 4 sq. meter, with a table and 2 chairs) at the exhibition area, as a poster or as a 20 min oral presentation at a session especially set up for demonstrations. It is also possible to organize the presentation of the same demo in more than one format.

Abstract
Due to the commoditization of the depth sensor, application of the depth sensor is expanding. We made a prototype of the virtual keyboard which is inexpensive, easy to carry, and playable of various sounds without choosing the place, just using a camera with the depth sensor, a notebook PC and a paper keyboard. The system automatically detects the position of the paper keyboard from the camera image and calibrates the area of each key. Then, based on the information from the depth sensor, it detects the finger’s touch and its position on the key by the background subtraction method. Although it is difficult with our system to express the strength of the keystrokes on the actual keyboard, our system can provide new functions such as sound effects by the finger movement on the touching key. Our touch detection with depth sensor has a disadvantage on the position accuracy compared with that of touch panels, the system can detect any number of touches simultaneously, and also realize effect functions corresponding to the height of the finger from the key surface. We consider it is possible to propose musical instruments with high entertainment that can be enjoyed from children to adults.

Brief Bio
Seiichi Gohshi is a professor of Kugakuin University. He received his BS degree, MS degree and PhD degree from Waseda University in 1979, 1981 and 1997. He joined Japan Broadcasting Corporation (NHK) in 1981. He started his research at NHK Science Technical Research Laboratories (STRL) in 1984. He helped to develop the HDTV broadcasting system, transmission systems, and signal processing systems. He was the project leader of the Super Hi-Vision (8K) transmission system and successfully conducted the first Super Hi-Vision transmission test at IBC2008. He also developed a watermark system that was used in movie theaters. He joined Sharp Corporation as a division deputy general manager in 2008 and developed high resolution systems. He is currently a professor of Kogakuin University. His research interests are video and image signal processing especially for super resolution and forensic technologies.

Abstract
In recent years, smartphones have become one of the most important devices in our daily lives. The young generation tends to watch films and television (TV) content on their smartphones rather than on conventional TVs. For improving image quality, TV manufacturers have to consider various signal processing methods. However, smartphone manufacturers only have to consider the screen resolution category such as HDTV or 4K resolution. Although many super resolution (SR) technologies have been proposed, most of them are very complex. Some SR technologies are installed in TV sets while new SR chips are constantly being development. Currently, many 4K TV sets are equipped with SR. However, employing SR chips in smartphones is difficult owing to their additional space and power requirements. If these issues are resolved, SR has to be developed and fine-tuned for compatibility with both still images (webpages) and moving images (videos), which is difficult because the characteristics of both vary considerably. We therefore propose SR with nonlinear processing to overcome these difficulties, wherein the digital filters are changed for still images and videos. We conducted subjective assessments to prove that SR improves the resolution of still images as well as videos.
