We present a visualization system that helps designers conceptualise interactions in a virtual environment (VE). We use eventcondition-action triads (triggersets) for specifying interactions, and provide multiple visualizations: sequence diagrams, floorplans and timelines. We present a two part study: sequencing VE interactions accurately and debugging mistakes. Subjects were divided into two g...

Many physical problems in the real world are frequently modeled by ordinary differential equations (ODEs). Real-life usually non-linear, numerical methods therefore needed to approximate their solution. We consider different viz., Explicit (Forward) and Implicit (Backward) Euler method, Classical second-order Runge-Kutta (RK2) method (Heun’s or Improved method), Third-order (RK3) Fourth-order (RK...

We describe our current work on volume visualization techniques developed with the aim to enhance interactive exploration of medical datasets. Volumetric lenses can be applied to a volume dataset to interactively focus regions of interest within these datasets. During rendering the parts of a volume dataset intersecting the lens, which is defined by a convex 3D shape, are rendered using a diffe...

Robotic system often use simultaneous localization and mapping method in their operations. Most of the calculation stored as a nested array with multiple level and dimension. SLAM data contains robot movement, object detection and relation between them. This system visualize SLAM data into a map containing robot historical position, object position and relation between object and robot that sho...

Direct-touch interaction is receiving an increasing amount of attention in the HCI domain and has recently been applied to some problems in information visualization. However, the field of scientific visualization has not seen much work on how direct-touch interaction could benefit the interactive visualization process. One reason may be that scientific visualization typically deals with datase...
