Hand and Mind: What Gestures Reveal about Thought

An interactive video display system. A display screen is for displaying a visual image for presentation to a user. A camera is for detecting an object in an interactive area located in front of the display screen, the camera operable to capture three-dimensional information about the object. A computer system is for directing the display screen to change the visual image in response to the object.

▶ Addresses the accessibility, usability, and, ultimately, acceptability of Information Society Technologies by anyone, anywhere, at anytime, and through any media and device. ▶ Focuses on theoretical, methodological, and empirical research, of both technological and non-technological nature. ▶ Features papers that report on theories, methods, tools, empirical results, reviews, case studies, and best-practice examples.

Universal access in the information society

Inevitably, reading is one of the requirements to be undergone. To improve the performance and quality, someone needs to have something new every day. It will suggest you to have more inspirations, then. However, the needs of inspirations will make you searching for some sources. Even from the other people experience, internet, and many books. Books and internet are the recommended media to help you improving your quality and performance.

Introducing a new hobby for other people may inspire them to join with you. Reading, as one of mutual hobby, is considered as the very easy hobby to do. But, many people are not interested in this hobby. Why? Boring is the reason of why. However, this feel actually can deal with the book and time of you reading. Yeah, one that we will refer to break the boredom in reading is choosing the myth of the paperless office as the reading material.

The Myth of the Paperless Office

While eye tracking has a high potential for fast selection tasks, it is often regarded as error-prone and unnatural, especially for gaze-only interaction. To improve on that, we propose gaze-supported interaction as a more natural and effective way combining a user's gaze with touch input from a handheld device. In particular, we contribute a set of novel and practical gaze-supported selection techniques for distant displays. Designed according to the principle gaze suggests, touch confirms they include an enhanced gaze-directed cursor, local zoom lenses and more elaborated techniques utilizing manual fine positioning of the cursor via touch. In a comprehensive user study with 24 participants, we investigated the potential of these techniques for different target sizes and distances. All novel techniques outperformed a simple gaze-directed cursor and showed individual advantages. In particular those techniques using touch for fine cursor adjustments (MAGIC touch) and for cycling through a list of possible close-to-gaze targets (MAGIC tab) demonstrated a high overall performance and usability.

Look & touch: gaze-supported target acquisition

Creating and editing large graphs and node-link diagrams are crucial activities in many application areas. For them, we consider multi-touch and pen input on interactive surfaces as very promising. This fundamental work presents a user study investigating how people edit node-link diagrams on an interactive tabletop. The study covers a set of basic operations, such as creating, moving, and deleting diagram elements. Participants were asked to perform spontaneous gestures for 14 given tasks. They could interact in three different ways: using one hand, both hands, as well as pen and hand together. The subjects' activities were observed and recorded in various ways, analyzed and enriched with think-aloud data. As a result, we contribute a user-elicited collection of touch and pen gestures for editing node-link diagrams. The study provides valuable insight how people would interact on interactive surfaces for this as well as other tabletop domains.

Investigating multi-touch and pen gestures for diagram editing on interactive surfaces

In order to improve the three-dimensional (3D) exploration of virtual spaces above a tabletop, we developed a set of navigation techniques using a handheld magic lens. These techniques allow for an intuitive interaction with two-dimensional and 3D information spaces, for which we contribute a classification into volumetric, layered, zoomable, and temporal spaces. The proposed PaperLens system uses a tracked sheet of paper to navigate these spaces with regard to the Z-dimension (height above the tabletop). A formative user study provided valuable feedback for the improvement of the PaperLens system with respect to layer interaction and navigation. In particular, the problem of keeping the focus on selected layers was addressed. We also propose additional vertical displays in order to provide further contextual clues.

To provide intuitive ways of interacting with media data, this research work addresses the seamless combination of sensor-enabled phones with large displays. An intuitive basic set of tilt gestures is introduced for a stepwise or continuous interaction with both mobile applications and distant user interfaces by utilizing the handheld as a remote control. In addition, we introduce throwing gestures to transfer media documents and even running interfaces to a large display. To improve usability, data and interfaces can be thrown from a mobile phone to a distant screen and also fetched back to achieve mobility. We demonstrate the feasibility of the interaction methods with several advanced application prototypes facilitating a natural flow of interaction.
