abstract = {This paper presents Smoothed Pointing, a velocity-based precision enhancing technique for remote pointing by means of absolute devices. After discussing the most recent related work concerning the problem of accuracy in remote pointing by handheld input devices, we introduce the distinctive features of the Control-Display adaptation technique we have designed to: i) reduce the effect of both noise in input device signals and of hand tremors on the cursor stability; and ii) increase the accuracy of pointing when performed on large, high resolution displays. Moreover, we describe a 10 second calibration procedure to determine the filtering parameters, so as to free the user from a manual set up.},

abstract = {Several interaction metaphors and techniques have been proposed to allow a natural interaction in virtual environments. Usually all these techniques are designed to be used with input devices such as wands, 3D mice or gloves. However, the availability of a new generation of auto-stereoscopic displays now makes it possible to exploit virtual experiences in new scenarios. In this paper we propose a variation of the ray-casting technique suitable for use with a standard mouse. With this proposed technique, users can move a 3D cursor in the virtual world without worrying about the third dimension and without losing the level of immersion provided by the 3D display.},

abstract = {Three-dimensional virtual environments are becoming more and more important for the inspection of volumetric medical data reconstructed from slices of images coming from Magnetic Resonance Imaging (MRI), Computer Tomography (CT), Positron Emission Tomography (PET) instrumentations. The possibility to visualize and interact with three-dimensional reconstructed organs while being immersed into a virtual environment, provides doctors a very naturalistic way to investigate patient's anatomy. However, most 3D user interfaces for immersive and semiimmersive virtual reality applications lack in usability or make not possible a user-friendly interaction. In this paper we present new flavors of existing 3D interaction techniques specifically designed for interacting with volumetric medical data in a semi-immersive virtual environment by using the Nintendo Wiimote controller as 3D user interface.},
