We present elastic cursor and elastic edge, new interaction techniques for seamless edge-scroll. Through the use of light-weight physical simulations of elastic behavior on interface elements, we can improve precision, usability, and cueing on the use of edge-scroll in scrollable windows or screens, and make experiences more playful and easier to learn.
Poor scalability is a long standing problem in multi-user MIMO (MU-MIMO) networks: in order to select concurrent uplink users with strong channel orthogonality and thus high total capacity, channel state information (...

software debugging is tedious and time consuming. To reduce the manual effort needed for debugging, researchers have proposed a considerable number of techniques to automate the process of fault localization;in particular, techniques based on information retrieval (IR) have drawn increased attention in recent years. Although reportedly effective, these techniques have some potential limitations that may affect their performance. First, their effectiveness is likely to depend heavily on the quality of the bug reports;unfortunately, high-quality bug reports that contain rich information are not always available. Second, these techniques have not been evaluated through studies that involve actual developers, which is less than ideal, as purely analytical evaluations can hardly show the actual usefulness of debugging techniques. The goal of this work is to evaluate the usefulness of IR-based techniques in real-world scenarios. Our investigation shows that bug reports do not always contain rich information, and that low-quality bug reports can considerably affect the effectiveness of these techniques. Our research also shows, through a user study, that high-quality bug reports benefit developers just as much as they benefit IR-based techniques. In fact, the information provided by IR-based techniques when operating on high-quality reports is only helpful to developers in a limited number of cases. And even in these cases, such information only helps developers get to the faulty file quickly, but does not help them in their most time consuming task: understanding and fixing the bug within that file.

This work presents a method of 3D printing hair-like structures on both flat and curved surfaces. It allows a user to design and fabricate hair geometry that is smaller than 100 micron. We built a software platform to let one quickly define a hair's angle, thickness, density, and height. The ability to fabricate customized hair-like structures expands the library of 3D-printable shape. We then present several applications to show how the 3D-printed hair can be used for designing toy objects.

In this paper, we present BitDrones, a platform for the construction of interactive 3D displays that utilize nano quadcopters as self-levitating tangible building blocks. Our prototype is a first step towards supporting interactive mid-air, tangible experiences with physical interaction techniques through multiple building blocks capable of physically representing interactive 3D data.

Paper Mechatronics is a novel interdisciplinary design medium, enabled by recent advances in craft technologies: the term refers to a reappraisal of traditional papercraft in combination with accessible mechanical, electronic, and computational elements. I am investigating the design space of paper mechatronics as a new hands-on medium by developing a series of examples and building a computational tool, FoldMecha, to support non-experts to design and construct their own paper mechatronics models. This paper describes how I used the tool to create two kinds of paper mechatronics models: walkers and flowers and discuss next steps.

As interactions with everyday handheld devices and objects become increasingly common, a more seamless and effortless identification and personalization technique will be essential to an uninterrupted user experience. In this paper, we present Zensei, a user identification and customization system using human body bioimpedance sensing through multiple electrodes embedded into everyday objects. Zensei provides for an uninterrupted user-device personalization experience that is difficult to forge because it uses both the unique physiological and behavioral characteristics of the user. We demonstrate our measurement system in three exemplary device configurations that showcase different levels of constraint via environment-based, whole-body-based, and handheld-based identification scenarios. We evaluated Zensei's classification accuracy among 12 subjects on each configuration over 22 days of collected data and report our promising results.

We present Color Sommelier, an interactive color recommendation system based on community-generated color palettes that helps users to choose harmonious colors on the fly. We used an item-based collaborative filtering technique with Adobe Color CC palettes in order to take advantage of their ratings that reflect the general public?s color harmony preferences. Every time a user chooses a color(s), Color Sommelier calculates how harmonious each of the remaining colors is with the chosen color(s). This interactive recommendation enables users to choose colors iteratively until they are satisfied. To illustrate the usefulness of the algorithm, we implemented a coloring application with a specially designed color chooser. With the chooser, users can intuitively recognize the harmony score of each color based on its bubble size and use the recommendations at their discretion. The Color Sommelier algorithm is flexible enough to be applicable to any color chooser in any software package and is easy to implement.
