Haptic reproduction and interactive visualization of a beating heart for cardiovascular surgery simulation.

This paper aims to achieve haptic reproduction and real-time visualization of a beating heart for cardiac surgery simulation. Unlike most forgoing approaches, the authors focus on time series datasets and propose a new framework for interactive ...

Does pornography-blocking software block access to health information on the Internet?

CONTEXT: The Internet has become an important tool for finding health information, especially among adolescents. Many computers have software designed to block access to Internet pornography. Because pornography-blocking software cannot perfectly ...

Adaptive spatiotemporal receptive field estimation in the visual pathway.

The encoding properties of the visual pathway are under constant control from mechanisms of adaptation and systems-level plasticity. In all but the most artificial experimental conditions, these mechanisms serve to continuously modulate the spatial and ...

A methodology for objective assessment of errors: an example using an endoscopic sinus surgery simulator.

A well-proven methodology (the modified Delphi method) was used to generate a first-order approximation of errors that should be measured in a virtual reality surgical simulator (the ES3). The methodology and the errors derived were crafted in such a way ...

The representation of peripheral neural activity in the middle-latency evoked field of primary auditory cortex in humans(1).

Short sweeps with increasing instantaneous frequency (up-chirps) designed to compensate for the propagation delay along the human cochlea enhance the magnitude of wave V of the auditory brainstem responses, while time reversed sweeps (down-chirps) reduce ...

Synthetic faces, face cubes, and the geometry of face space.

To simplify the study of visual face processing, we introduce a novel class of synthetic face stimuli based upon 37 measurements (head shape, feature locations, etc.) extracted from individual face photographs in both frontal and 20 degrees side views. ...

Virtual reality flexible cystoscopy: a validation study.

OBJECTIVES: To validate a flexible cystoscopy simulator by determining if it could differentiate between expert and novice cystoscopists. SUBJECTS AND METHODS: Seventeen subjects (10 novices with no previous endoscopic experience and seven urologists who ...

A simulation study of the degrees of freedom of movement in reaching and grasping.

The question of independently controlled components in the act of reaching and grasping has attracted interest experimentally and theoretically. Data from 35 studies were recently found consistent with simulated kinematic finger and thumb trajectories ...
