We survey the state of the art of spatial interfaces for 3D visualization. Interaction techniques
are crucial to data visualization processes and the visualization research community has …

Computer graphics applications controlled through natural gestures are gaining increasing
popularity these days due to recent developments in low-cost tracking systems and gesture …

Augmented reality (AR) and virtual reality (VR) technologies create exciting new
opportunities for people to interact with computing resources and information. Less exciting …

Raycasting is the most common target pointing technique in virtual reality environments.
However, performance on small and distant targets is impacted by the accuracy of the …

We present a method of rendering aerial and volumetric graphics using femtosecond lasers.
A high-intensity laser excites physical matter to emit light at an arbitrary three-dimensional …

The presence of fully-occluded targets is common within virtual environments, ranging from
a virtual object located behind a wall to a datapoint of interest hidden in a complex …

We present an interaction model for beyond-desktop visualizations that combines the
visualization reference model with the instrumental interaction paradigm. Beyond-desktop …

In 3D environments, objects can be difficult to select when they overlap, as this affects
available target area and increases selection ambiguity. We introduce Outline Pursuits …

Sphere is a multi-user, multi-touch-sensitive spherical display in which an infrared camera
used for touch sensing shares the same optical path with the projector used for the display …

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 …
