We have developed a technique, Aggregate Towers, that allows geospatial data to be visualized across a range of map scales. We use a combination of data aggregation algorithms and dynamically aggregating data markers (e.g., icons or symbols) to accommodate interactive zooming by a user while maintaining a representation that remains intuitive, consistent across multiple scales, and uncluttered....

MOTIVATION Extensions have been made to the RHMAPPER-1.1 package. One set of extensions computes the totally linked markers and uses the results as input to the salient RHMAPPER functions. The second set of extensions uses TKperl to provide an interactive interface for ease of querying the database and displaying maps. AVAILABILITY The extensions can be obtained via ftp.sanger.ac.uk/pub/zmapp...

We propose a technique to do interactive crowd simulation on mobile devices within an Augmented Reality (AR) framework. We localize the camera in a prepared environment that includes a set of natural markers. We use least squares optimization to obtain extrinsic camera parameters. During tracking, the users can create paths for the agents to follow through touch inputs. User-specified paths are...

New high throughput DNA technologies resulted in a disproportion between the high number of scored markers for the mapping populations and relatively small sizes of the genotyped populations. Correspondingly, the number of markers may, by orders of magnitude, exceed the threshold of recombination resolution achievable for a given population size. Hence, only a small part of markers can be genui...

the purpose of this study was to investigate the impact of blended learning and multimedia software on iranian esp students' vocabulary learning. to this end, 120 iranian esp learners were assigned to two groups: the experimental and control groups. the experimental group received instructions through multimedia software while the control group received traditional instructions. the data were c...

— Metacognition is associated with planning, monitoring, evaluating and repairing performance Designers of elearning systems can improve the quality of their environments by explicitly structuring the visual and interactive display of learning contexts to facilitate metacognition. Typically page layout, navigational appearance, visual and interactivity design are not viewed as major factors in ...

The acquisition of human motion data is of major importance for creating interactive virtual environments, intelligent user interfaces, and realistic computer animations. Todays performance of off-the-shelf computer hardware enables marker-free non-intrusive optical tracking of the human body. In addition, recent research shows that it is possible to efficiently acquire and render volumetric sc...
