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)
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)
Surgical simulation can provide high-fidelity training that increases the diffusion of innovative and less-invasive procedures while decreasing the surgeon's learning curve. M edical surgery involves a high degree of skill and experience, making the learning curve for medical trainees quite long. For instance, in eye cataract surgery, despite it only taking(More)
We 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 supports three scenarios: an instructor and a trainee in geographically distant locations interacting in real-time having the instructor tele-mentor the trainee using haptic(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)
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 simulation,(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)
Haptic-based Virtual Reality (VR) applications have many merits. What is still obscure, from the designer's perspective of these applications, is the experience the users will undergo when they use the VR system. Quality of Experience (QoE) is an evaluation metric from the user's perspective that unfortunately has received limited attention from the(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)
