Object search: supporting structured queries in web search engines
… may include her name, university, and research interests. Both types of pages may include additional ambiguous information. General search engines (GSEs) do not support queries over these types of data because they ignore the web document semantics. Conversely, describing requisite …

Keyword-based object search and exploration in multidimensional text databases
… system TEXplorer that integrates keyword-based object ranking with the aggregation and exploration power of OLAP in a text database with rich structured attributes available, e.g., a product review database. TEXplorer can be implemented within a multi-dimensional text database, where each row is …

Towards Reinforcement-Learning-based Robot Navigation with 3D Scene Graphs
… in several robotics applications, including search and rescue operations. RL circumvents the need to manually specify a control policy for navigation and allows capturing aspects that are difficult to describe without relying on learning, e.g., that survivors or objects of interest are more …

Monitoring eye movements to uncover the role of visual context in the access to verb-complement information during sentence comprehension
… relation between the verb and its direct object (e.g. " The woman burned the candle "), and a neutral construction with a transitive perception verb (e.g. " The woman admired the candle "). Moreover, we conducted an object search task to monitor the time subjects took to look at the target …

Robot Motions that Mitigate Uncertainty
… part introduces a risk-aware motion model for searching for a target object in an unknown environment. To illustrate practical application, consider a situation such as disaster response or search-and-rescue, where it is imperative for ground vehicles to swiftly reach critical locations. …

An ERP Investigation into the Influence of Spatial Relevance on Attentional Deployment
In visual search, top-down task knowledge and bottom-up stimulus salience interact to determine where observers are most likely to attend. Past research has demonstrated that during search tasks, scene regions with a high probability of containing the target (spatially relevant regions) are more …

Towards Self-Supervised Object Representations and 3D Scene Graph Based Navigation
… the art in dense 2D semantic segmentation and 3D object pose estimation to improve scene graph construction and enable navigation in real-life environments. First, we tackle the scalability problem of data annotation for deep semantic segmentation and introduce a simple training approach for dense …

Context Driven Scene Understanding
Understanding objects in complex scenes is a fundamental and challenging problem in computer vision. Given an image, we would like to answer the questions of whether there is an object of a particular category in the image, where is it, and if possible, locate it with a bounding box or pixel-wise …

Navigating the Unseen: A Haptic Glove for Peripersonal Navigation in Low-Visibility Scenarios
Effective interaction with objects within arm's reach, known as peripersonal navigation, is essential to performing everyday activities as well as specialized tasks in fields such as healthcare, construction, and assistive technology. However, this ability can be substantially impaired in cluttered …
