When directly manipulating 3D objects in an immersive environment we cannot normally achieve the accuracy and control that we have in the real world. This reduced accuracy stems from hand instability. We present PRISM, which dynamically adjusts the C/D ratio between the hand and the controlled object to provide increased control when moving slowly and(More)
Naturally occurring G-quadruplex structural motifs, formed by guanine-rich nucleic acids, have been reported in telomeric, promoter and transcribed regions of mammalian genomes. G-quadruplex structures have received significant attention because of growing evidence for their role in important biological processes, human disease and as therapeutic targets.(More)

Nucleic acids containing guanine tracts can form quadruplex structures via non-Watson-Crick base pairing. Formation of G-quadruplexes is associated with the regulation of important biological functions such as transcription, genetic instability, DNA repair, DNA replication, epigenetic mechanisms, regulation of translation, and alternative splicing.(More)
We present a novel text input interface for immersive virtual environments called CTD, or “Connect the Dots”. The CTD interface is a small virtual panel containing a grid of dots the user can connect to form alphanumeric characters using a hand held stylus. Coupled with a physical paddle or desk for force feedback, the CTD provides an intuitive text input(More)
We present several additions to orbital viewing in immersive virtual environments, including a method of blending standard and orbital viewing to allow smoother transitions between modes and more flexibility when working in larger workspaces. Based on pilot studies, we present methods of allowing users to manipulate objects while using orbital viewing in a(More)
