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.

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

With this work, we demonstrate our concept of Reality-Based Information Retrieval. Our principal idea is to bring Information Retrieval closer to the real world, for a new class of future, immersive IR interfaces. Technological advances in computer vision and machine learning will allow mobile Information Retrieval to make even better use of the people's surroundings and their ability to interact with the physical world. Reality-Based Information Retrieval augments the classic Information Retrieval process with context-dependent search cues and situated query and result visualizations using Augmented Reality technologies. We briefly describe our concept as an extension of the Information Retrieval pipeline and present two prototype implementations that showcase the potential of Reality-Based Information Retrieval.

This sketch reports on a new approach to facilitate theconstruction of interactive 3D graphics applications for theweb and introduces the component architecture and under-lying high-level languages Considering the huge improve-ments in graphics hardware and the fast evolving internettechnologies it seems surprising, that 3D applications arestill not widely used One problem is the dependency onproprietary 3D formats or the less successful VRML stan-dard Even with its promising successor X3D

Mobile devices are getting more and more powerful, however, interfaces for exploring multivariate network data on-the-go remain rare and challenging to realize. In this work, we present considerations as well as concepts on how to enable such exploration on mobile devices. Specifically, we discuss that an interface with force-directed node-link representation alongside additional views for investigating multivariate aspects and filter functionalities seems promising. Further, such an interface could be advanced by incorporating multiple mobile devices in parallel. As part of our ongoing investigations, we have realized an early prototype indicating the general feasibility of our concepts.

Towards Visualizing and Exploring Multivariate Networks on Mobile Devices

Manual point cloud registration is often a crucial step during the mapping of 3D point clouds and usually performed on a conventional desktop setup with mouse interaction. Since 3D point clouds are inherently spatial, these 2D applications suffer from impaired depth perception and inconvenient interaction. Nonetheless, there are few efforts to improve the usability of these applications. To address this, we propose an alternative setup, consisting of a stereoscopic display and an external hand tracker, allowing for enhanced depth perception and natural interaction without the need for body-worn devices or handheld controllers. We developed interaction techniques for point cloud alignment in 3D space, including visual feedback during alignment, and implemented a proof-of-concept prototype in the context of a surgical use case. We describe the use case, design and implementation of our concepts and outline future work. Herewith we provide a user-centered alternative to desktop applications for manual point cloud registration.

. Recent developments on solvers for abstract argumentation frameworks (AFs) made them capable to compute extensions for many semantics efﬁciently. However, for many input instances these solution spaces can become very large and incomprehensible. So far, for the further exploration and investigation of the AF solution space the user needs to use post-processing methods or handcrafted tools. To compare and explore the solution spaces of two selected semantics, we propose an approach that visually supports the user, via a combination of dimensionality reduction of argumentation extensions and a projection of extensions to sets of accepted or rejected arguments. We introduce the novel web-based visualization tool N EXAS that allows for an interactive exploration of the solution space together with a statistical analysis of the acceptance of individual arguments for the selected semantics, as well as provides an interactive correlation matrix for the acceptance of arguments. We validate the tool with a walk-through along three use cases.
