We present SymbiosisSketch, a hybrid sketching system that combines drawing in air (3D)
and on a drawing surface (2D) to create detailed 3D designs of arbitrary scale in an …

Issues such as hand and tracker jitter negatively affect user performance with the ray-casting
selection technique in 3D environments. This makes it difficult for users to perform tasks that …

Region selection is a fundamental task in interactive systems. In 2D user interfaces, users
typically use a rectangle selection tool to formulate a region using a mouse or touchpad …

Three-dimensional user interfaces (3D UIs) support user tasks in many non-traditional
interactive systems such as virtual environments and augmented reality. Although 3D UI …

3D object selection is more demanding when, 1) objects densly surround the target object,
2) the target object is significantly occluded, and 3) when the target object is dynamically …

Various interaction techniques have been developed for interactive 3D environments. This
paper presents an up‐to‐date and comprehensive review of the state of the art of non …

In this chapter, we briefly review the development of natural user interfaces and discuss their
role in providing human-computer interaction that is immersive in various ways. Then we …

3D selection in dense VR environments (eg, point clouds) is extremely challenging due to
occlusion and imprecise mid-air input modalities (eg, 3D controllers and hand gestures). In …

Data selection is a fundamental task in visualization because it serves as a pre-requisite to
many follow-up interactions. Efficient spatial selection in 3D point cloud datasets consisting …

Selection is one of the fundamental building blocks of all interactive virtual environment
systems. Selection is the ability of the user to specify which object, or sub-part of an object in …
