Image and video object selection
"Image and video object selection present fundamental research problems in the computer vision field and have many practical applications. They are important technologies in image and video editing, film production, robotics and autonomous driving etc. Previous methods have serious limitations for …

Design and Evaluation of 3D Multiple Object Selection Techniques
… important issue of three-dimensional multiple object selection (MOS) in immersive Virtual Environments (VEs). We have developed a taxonomy of the MOS task as a framework for exploring the design space of these techniques. In this thesis, we describe four techniques for selecting multiple …

Individualized selection of learning objects
… efforts on standardization of learning object metadata enable learners in a web-based educational system ubiquitous access to multiple learning resources. It is becoming more necessary and possible to provide individualized help with selecting learning materials to make the most suitable …

Image Vectorization
… for creating an editable vector graphic from an object in a raster image. Object selection is performed interactively in subsecond time by calling graph cut with each mouse movement. A renderable mesh is then computed automatically for the selected object and each of its (sub)objects by (1) …

Application of the Best-Example Theory of Categorization to Concept Development and Communication Training With Severely Handicapped Students
The effect of object selection on the development of generalized object categories, and generalized labeling of objects within categories, was investigated with severely handicapped students. Development of object categories was monitored through manual sign training. The effectiveness of three …

Implicit gaze interaction for information visualization
… a user’s interest in rendered visualization objects by collecting the gaze data and calculating the object group’s interest scores across selected visual features. With the interest model, We offer an implicit gaze interaction system that provides subtle interaction supports to improve …

Shape Estimation Using Graph Cut
… is mainly concerned with shape estimating of an object from its two-dimensional (2D) images. In this dissertation, various shape estimation problems are formulated as global optimization problems which are solved using graph cut. Particularly, an approach called graph cuts based active contours …

Illusory judgments under conditions of uncertainty: Reasoning errors related to paranormal and religious beliefs
… participants to choose a strategy for target object selection. Study 2 expanded upon Study 1 by giving participants an additional choice strategy (e.g., a computer's selection). In both Study 1 and Study 2, participants relied on the paranormal strategy (e.g., a psychic) to a greater degree …

Spontaneous speech recognition using visual context-aware language models
… that performs speech understanding for visual object selection. An experimental task was created in which people were asked to refer, using speech alone, to objects arranged on a table top. During training, Fuse acquires a grammar and vocabulary from a "show-and-tell" procedure in which visual …

VoiceLink : a speech interface fore responsive media
… the HyperSoap module allows viewers to select objects and access related information by saying objects' names. We also built a speech software library for Isis, which allows users to develop speech aware applications in the Isis programming environment. We addressed a number of problems when …

Robots as Minions, Sidekicks, and Apprentices: Using Wearable Muscle, Brain, and Motion Sensors for Plug-and-Play Human-Robot Interaction
… and teleoperate robot minions that perform object selection or navigation in mock safety-critical or inaccessible settings. Robot sidekicks collaborate with users to jointly lift objects and perform assemblies. Finally, robot apprentices generalize cable-routing trajectories or grasping …

Increasing Selection Accuracy and Speed through Progressive Refinement
Although many selection techniques have been proposed and developed over the years, selection by pointing is perhaps the most popular approach for selection. In 3D interfaces, the laser-pointer metaphor is commonly used, since users only have to point to their target from a distance. However, the …

Wearing the Wunderkammer: A practice-led analysis of cabinets of curiosities, examining the quality of curiosity and applying it to a fashion exhibition
… to the modern museum (Hill, 1986: 148). Objects within them generally fell within one of two broad categories: naturalia (natural objects) and artificialia (man-made artefacts)(1). Artificialia included items of fashion2, primarily from non-European cultures. Although the reasons for the …

Tangible User Interface for CAVE based on Augmented Reality Technique
… popular toolkit for use in AR projects. Physical objects (props) are used as input devices instead of any tethered electromagnetic trackers. An off-the-shelf webcam is used to get tracking input data. A unique pattern marker is attached to the prop, which is easily and simply tracked by ARToolKit. …
