چکیده
Information seekers often need to perceive the organization of the document content to find the destination in the information space. Much of this task involves navigating the information space. This article primarily delineates essential premises concerning navigation in information space. The paper also discusses how cognitive abilities, particularly spatial ability, affects user’s navigation pattern. Problematic issues such as Lost in Hyperspace and Cognitive Overhead are also discussed. Finally, this paper explores prospective ideas and schemes to make navigation more effective and enjoyable in future.

متن کاملA New Method of Mobile Robot Navigation: Shortest Null Space
In this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. The robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (SNS) toward the goal. In the case of no obstacle, SNS was a direct path from the robot to goal; however, in the presence of obstacles, SNS was a space around the r...

متن کاملA Hierarchical SLAM/GPS/INS Sensor Fusion with WLFP for Flying Robo-SAR's Navigation
In this paper, we present the results of a hierarchical SLAM/GPS/INS/WLFP sensor fusion to be used in navigation system devices. Due to low quality of the inertial sensors, even a short-term GPS failure can lower the integrated navigation performance significantly. In addition, in GPS denied environments, most navigation systems need a separate assisting resource, in order to increase the avail...
