An approach for Electroencephalogram (EEG) processing is presented. Along with the theoretical development of stochastic processing techniques, two application areas are suggested: EEG sleep recording analysis and Brain Computer Interface (BCI). Many methods have been already developed in the area of sleep staging, nevertheless the automatic scoring in not(More)
Multimedia systems and applications have recently started to integrate the sense of touch and force feedback in the human-computer interaction. Surprisingly, measuring the quality of experience (QoE) when haptic modality is incorporated in a virtual user interface has received limited attention from the research community. In this paper, we propose a(More)
In this paper, we will discuss our efforts in developing a hapto-visual application that medical students can use to gain valuable experience in performing eye cataract surgery on a human. Our application will support three scenarios: an instructor and a trainee in geographically distant locations interacting in real-time having the instructor tele-mentor(More)
Multimedia systems and applications have recently started to integrate the sense of touch and force feedback in the human-computer interaction. Surprisingly, measuring the quality of experience when haptic modality is incorporated in a graphical user interface has received limited attention from the research community. In this paper, we propose a taxonomy(More)
Haptic technologies and applications have received enormous attention in the last decade. The incorporation of haptic modality into multimedia applications adds excitement and enjoyment to an application. It also adds a more natural feel to multimedia applications, that otherwise would be limited to vision and audition, by engaging as well the user’s sense(More)
As medical surgery is usually a complex and complicated procedure, medical trainees must acquire specific skills and plenty of experience before attempting to perform such a procedure in a real-world setting. The goal of surgical simulation is to provide high-fidelity training to increase the diffusion of innovative and less-invasive procedures while(More)
Undesired physical fatigue reduces the overall Quality of Experience (QoE) of virtual reality haptics applications. Detecting fatigue is the first step in rectifying this problem. Fatigue in usability analysis is usually detected through conducting questionnaires and observations. This paper introduces an objective indirect discovery of user's fatigue(More)
– In this paper, we discuss the technologies and approaches utilized in developing a cataract eye surgery simulation that will be used for training novice surgeons. The three different techniques described in this paper, are all hapto-visual techniques that resulted in three different implementations of the application: 2D simulation, 3D immersive(More)
