Otological microsurgery is delicate and requires high dexterity in bad ergonomic conditions. To assist surgeons in these indications, a teleoperated system, called RobOtol, is developed. This robot enhances gesture accuracy and handiness and allows exploration of new procedures for middle ear surgery. To plan new procedures that exploit the capacities given by the robot, a surgical simulator is...

Informed consent is the cornerstone of human research subject protection. Many subjects sign consent documents without understanding the study purpose, procedures, risks, benefits, and their rights. Proof of comprehension is not required and rarely obtained. Understanding might improve by using an interactive system with multiple options for hearing, viewing and reading about the study and the ...

In many network routing problems several conflicting objectives must be considered. Even for the bi-objective shortest path problem, generating and presenting the whole set of nondominated solutions (paths) to a decision maker, in general, is not effective because the number of these paths can be very large. Interactive procedures are adequate to overcome these drawbacks. Current et al. [1] pro...

Partitioning is often used to support better graph drawing; in this paper, we describe an interactive system in which graph drawing is used to support better partitioning. In our system the user is presented with a drawing of a current network partitioning, and is responsible for choosing appropriate optimization procedures and for focusing their application on portions of the network. Our pilo...

Volume segmentation is an important part of medical diagnostics, and fast solutions which nevertheless can handle large datasets are required. This paper presents a diffusion-based method that can be used for volume smoothing and segmentation purposes, and has been implemented on the GPU in order to achieve interactive performance. We describe the nonlinear isotropic and anisotropic diffusion m...

This paper gives an overview of my PhD research that aims at contributing toward the definition of a class of interfaces for music creation that target non-musicians. In particular, I am focusing on the differences on design and evaluation procedures with respect to traditional interfaces for music creation that are usually intended to be used by musicians. Supported by a number of preliminary ...

Fluid dynamics applications require a good understanding of the underlying physical phenomena. Therefore, effective procedures are necessary for analyzing and visualizing the various physical fields. Beside interactive and perceptually efficient techniques for visualizing flow fields directly, there is strong demand for methods that uncover hidden flow structures. Some recently developed featur...

This paper presents systematic approach to evaluation of compatibility in a broad sense for user-centered and, particularly, user-model based information and industrial control interactive systems. Compatibility is considered as a multi-dimensional multi-level frame and criteria complex for coherent analysis, design, evaluation, redeployment and operational enduser-centered adaptation of human-...

moving in line with the postulation that metadiscourse (md) markers help transform a dry and tortuous piece of text into a coherent and reader-friendly one, the researchers in the current study attempted to investigate the effect different metadiscourse markers might have on iranian efl learners’ perception of written texts. to this end, 120 undergraduate english students were given three diffe...

metadiscourse is a widely used term in current discourse analysis and language education, referring to an interesting, and relatively new approach to conceptualizing interaction between text producers and their texts and between text producers and users. despite the growing importance of the term, however, it is often understood in different ways and used to refer to different aspects of langua...
