A 3D virtual space consists of non-movable and movable objects to provide more real environment, where movable objects can be transformed by translating, rotating and scaling. In most systems, the movement of objects can be performed by mice and keyboards. In this paper, we propose a controlling interface scheme for transforming the objects in the 3D virtual space based on gestures of left and ...

When, in visual and haptic search, a target is easily found among distractors, this is called a pop-out effect. The target feature is then believed to be salient, and the search is performed in a parallel way. We investigated this effect with movable stimuli in a haptic search task. The task was to find a movable ball among anchored distractors or the other way round. Results show that reaction...

This paper presents the numerical simulations of flow and dam body sediment transport over a movable bed due to an earthfill break. The RANS equations, together with k-ω SST turbulent model, are employed. phase characteristic parameter is used as phases air, water, sediment, bulk body. system equations solved numerically using PISO algorithm. model first verified break experimental data from li...
