A general principle for all user interface design is to go through all of your design elements and remove them one at a time. If the design works as well without a certain design element, kill it.

Chia, Pern Hui, Yamamoto, Yusuke and Asokan, N. (2012): Is this app safe?: a large scale study on application permissions and risk signals. In: Proceedings of the 2012 International Conference on the World Wide Web 2012. pp. 311-320.

Third-party applications (apps) drive the attractiveness of web and mobile application platforms. Many of these platforms adopt a decentralized control strategy, relying on explicit user consent for granting permissions that the apps request. Users have to rely primarily on community ratings as the signals to identify the potentially harmful and inappropriate apps even though community ratings typically reflect opinions about perceived functionality or performance rather than about risks. With the arrival of HTML5 web apps, such user-consent permission systems will become more widespread. We study the effectiveness of user-consent permission systems through a large scale data collection of Facebook apps, Chrome extensions and Android apps. Our analysis confirms that the current forms of community ratings used in app markets today are not reliable indicators of privacy risks of an app. We find some evidence indicating attempts to mislead or entice users into granting permissions: free applications and applications with mature content request more permissions than is typical; 'look-alike' applications which have names similar to popular applications also request more permissions than is typical. We also find that across all three platforms popular applications request more permissions than average.

Yamamoto, Yusuke and Tanaka, Katsumi (2011): Enhancing credibility judgment of web search results. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 1235-1244.

In this paper, we propose a system for helping users to judge the credibility of Web search results and to search for credible Web pages. Conventional Web search engines present only titles, snippets, and URLs for users, which give few clues to judge the credibility of Web search results. Moreover, ranking algorithms of the conventional Web search engines are often based on relevance and popularity of Web pages. Towards credibility-oriented Web search, our proposed system provides users with the following three functions: (1) calculation and visualization of several scores of Web search results on the main credibility aspects, (2) prediction of user's credibility judgment model through user's credibility feedback for Web search results, and (3) re-ranking of Web search results based on user's predicted credibility model. Experimental results suggest that our system enables users -- in particular, users with knowledge about search topics -- to find credible Web pages from a list of Web search results more efficiently than conventional Web search interfaces.

Yamamoto, Yusuke, Uchiyama, Hideaki and Kakehi, Yasuaki (2011): onNote: playing printed music scores as a musical instrument. In: Proceedings of the 2011 ACM Symposium on User Interface Software and Technology 2011. pp. 413-422.

This paper presents a novel musical performance system named onNote that directly utilizes printed music scores as a musical instrument. This system can make users believe that sound is indeed embedded on the music notes in the scores. The users can play music simply by placing, moving and touching the scores under a desk lamp equipped with a camera and a small projector. By varying the movement, the users can control the playing sound and the tempo of the music. To develop this system, we propose an image processing based framework for retrieving music from a music database by capturing printed music scores. From a captured image, we identify the scores by matching them with the reference music scores, and compute the position and pose of the scores with respect to the camera. By using this framework, we can develop novel types of musical interactions.
