Smartphones in general and Android particular are increasingly shifting into the focus of cybercriminals. For understanding threat to security privacy it is important for researchers analyze malicious software written these systems. The exploding number malware calls automation analysis. In this paper, we present Mobile-Sandbox, a system designed automatically applications two novel ways: (1) combines static dynamic analysis, i.e., results analysis used guide extend coverage executed code,...
Several fields of science are experiencing a "replication crisis" that has negatively impacted their credibility. Assessing the validity contribution via replicability its experimental evidence and reproducibility analyses requires access to relevant study materials, data, code. Failing share them limits ability scrutinize or build-upon research, ultimately hindering scientific progress.
The open-source model of software development is an established and widely used method that has been making inroads into several scientific disciplines which use software, thereby also helping much-needed efforts at replication results. However, our own discipline HCI does not seem to follow this trend so far. We analyze the entire body papers from CHI 2016 2017 regarding releases, compare results with bioinformatics. Based on comparison, we suggest future directions for publication...
We present Shoe me the Way, a novel tactile interface for eyes-free pedestrian navigation in urban environments. Our prototypical implementation can be fully integrated into users' own, regular shoes without permanent modifications. Interface use does not distract users from their surroundings. It thereby adds to safety and enables them explore environments more freely than is possible with prevailing mobile map-based systems. evaluated our prototype using two different modes study 21...
In recent years, a large amount of software for multitouch interfaces with various degrees similarity has been written. order to improve interoperability, we aim identify the common traits these systems and present layered architecture which abstracts similarities by defining between successive layers. This provides developers unified view types hardware. Moreover, allows easy integration existing software, as several alternative implementations each layer can co-exist. Finally, our...
Since its introduction in 2005, the TUIO protocol has been widely employed within a multitude of usage contexts tangible and multi-touch interaction. While simple versatile design still covers core functionality interactive tabletop systems, conceptual technical developments past decade also led to variety ad-hoc extensions modifications for specific scenarios. In this paper, we present an analysis strengths shortcomings 1.1, leading constitution extended abstraction model surfaces...
Multi-touch interfaces have been a focus of research in recent years, resulting development various innovative UI concepts. Support for existing WIMP interfaces, however, should not be overlooked. Although several approaches exist, there is still room improvement, particularly regarding implementation the "hover" state, commonly used mouse-based interfaces.
Ubiquitous tracking setups, covering large areas with many heterogeneous sensors of varying accuracy, require dedicated middleware to facilitate development stationary and mobile applications by providing a simple interface encapsulating the details sensing, calibration sensor fusion. In this paper we present centrally coordinated peer-to-peer architecture for ubiquitous tracking, where server computes optimal data flow configurations application clients, which are directly exchanging low...
Large-scale interactive surfaces are nearly ubiquitous in research labs and showrooms around the world today. However, unlike other recent technologies such as smartphones, they have not yet found their way into people's everyday lives. Possible reasons include high cost well a lack of suitable applications. In this paper, we present our prototypical implementation low-cost, unobtrusive surface, integrated with dining table real-world living room. To motivate approach, explore three...
This paper presents a curated collection of fictional abstracts for papers that could appear in the proceedings 2039 CHI Conference. It provides an opportunity to consider various visions guiding work HCI, futures toward which we (believe we) are working, and how research field might relate with broader social, political, cultural changes over next quarter century.
We present GISpL, the Gestural Interface Specification Language. GISpL is a formal language which allows both researchers and developers to unambiguously describe behavior of wide range gestural interfaces using simple JSON-based syntax. supports multitude input modalities, including multi-touch, digital pens, multiple regular mice, tangible or mid-air gestures.
Although public displays are increasingly being deployed in everyday situations, they still mostly used as auto-active information sources. Adding interactivity can help to attract and engage users. We report on the design in-the-wild evaluation of an interactive advert for a display tourist center. evaluate compare 3 different variants - non-interactive, interaction using body tracking, personal mobile devices with respect attracting attention from passersby. further these iterated version...
We present Seedmarkers, shape-independent topological markers that can be embedded in physical objects manufactured with common rapid-prototyping techniques. Many are optimized for technical performance while visual appearance or the feasibility of permanently merging marker and object is not considered. give an overview aesthetic properties a wide range existing conducted short online survey to assess perception popular designs. Based on our findings we introduce generation algorithm making...
The ubiquitous tracking (Ubitrack) approach uses spatial relationship graphs and patterns to support a distributed software architecture for augmented reality (AR) systems in which clients can produce, transform, transmit, consume data.
Despite widespread use of touch-enabled devices, the field software development has only slowly adopted new interaction methods for available tools. In this paper, we present our research on RefactorPad, a code editor editing and restructuring source touchscreens. Since entering modifying with on-screen keyboards is time-consuming, have developed set gestures that take program syntax into account support common maintenance tasks devices such as tablets. This work presents three main...
Remote video communication is now part of everyday life, also for families. At the same time, children encounter digital devices at an early age, but studies indicate that physical play still vital their development. To support a distance, we introduce two prototypes build around projection displays, WallWizard and TableCanvas. Both allow users to together remotely by combining elements on shared surfaces. We evaluated our through expert review, and, based this study, elaborate further...
