I N T R O D U C T I O N Pointing to a location on a graphics display is an elemental gesture in many forms of human-computer interaction (HCi). Pointing movements have been studied in an attempt to understand perceptual-motor processes(More)
The pharmacokinetics and metabolism of nateglinide were studied in six healthy male subjects receiving a single oral (120 mg) and intravenous (60 mg) dose of [14C]nateglinide in randomized order. Serial blood and complete urine and feces were collected for 120 h post dose. Nateglinide was rapidly (approximately 90%) absorbed, with peak blood and plasma(More)
Pointing movements with the hand were used to control directly a cursor to point to targets on a graphical display with different gain settings. A detailed analysis of both the tumor and hand movements showed how features of the movements scale over a wide range of distances and target widths. Cursor movements showed gain effects, while hand movements were(More)
The Virtual Hand Lab (VHL) is an an augmented reality envimnment for conducting experiments in human perception and motor performance that involve grasping, manipulation, and other 3D tasks that people perform with their hands. The hardware and software testbed supports both physical and virtual objects, and object behaviors that cm be specified in advance(More)
We describe two recent research projects: the Virtual Hand Laboratory, and Remote Manipulation in Endoscopic Surgery. The Virtual Hand Laboratory (VHL) is a prototype experimental tool for investigating human visuomotor coordination for object manipulation in augmented and virtual environments. The Remote Manipulation in Endoscopic Surgery (RMES) project(More)
Regenerative mechanisms reported in the hearts of lower vertebrates have been recapitulated in the mammalian milieu, and recent studies have provided strong evidence for cardiomyocyte turnover in humans. These findings speak to an emerging consensus that adult mammalian cardiomyocytes do have the ability to divide, and it stands to reason that enrichment of(More)
