We propose research on artificial fingernails which contain tiny displays and sensors. These fingernail displays greatly supplement other input and output channels, offering novel interaction possibilities. We present three contributions: (1) the general concept and use cases for fingernail displays, (2) a technique for capturing touch events at the fingernails and interaction methods supported by this technique, and (3) an overview of relevant research questions.

In this paper, we present our research on RefactorPad, a code editor for editing and restructuring source code on touchscreens. Since entering and modifying code with on-screen keyboards is time-consuming, we have developed a set of gestures that take program syntax into account and support common maintenance tasks on devices such as tablets. This work presents three main contributions: 1) a test setup that enables researchers and participants to collaboratively walk through code examples in real-time; 2) the results of a user study on editing source code with both finger and pen gestures; 3) a list of operations and some design guidelines for creators of code editors or software development environments who wish to optimize their tools for touchscreens.

For understanding the threat to security and privacy it is important for security researchers to analyze malicious software written for these systems. The exploding number of Android malware calls for automation in the analysis. In this paper, we present Mobile-Sandbox, a system designed to automatically analyze Android applications in two novel ways: (1) it combines static and dynamic analysis, i.e., results of static analysis are used to guide dynamic analysis and extend coverage of executed code, and (2) it uses specific techniques to log calls to native (i.e., "non-Java") APIs. We evaluated the system on more than 36,000 applications from Asian third-party mobile markets and found that 24% of all applications actually use native calls in their code.

This workshop proposes to explore the gap between attempts to formalize and structure development for multimodal interfaces in the research community on the one hand and the lack of adoption of these formal languages and frameworks by practitioners and other researchers on the other hand.

For understanding the threat to security and privacy, it is important for security researchers to analyze malicious software written for these systems. The exploding number of Android malware calls for automation in the analysis. In this paper, we present Mobile-Sandbox, a system designed to automatically analyze Android applications in novel ways: First, it combines static and dynamic analysis, i.e., results of static analysis are used to guide dynamic analysis and extend coverage of executed code. Additionally, it uses specific techniques to log calls to native (i.e., “non-Java”) APIs, and last but not least it combines these results with machine-learning techniques to cluster the analyzed samples into benign and malicious ones. We evaluated the system on more than 69,000 applications from Asian third-party mobile markets and found that about 21 % of them actually use native calls in their code.

However, this method has so far required a bulky projector-camera setup behind the screen. In this paper, we present a new approach to FTIR sensing by" inverting" the setup and placing the camera in front of the screen. This allows the use of unmodified flat screens as display, thereby dramatically shrinking the space required behind the screen and ...
