    Action-based Learning Assessment Method (ALAM) in Virtual Training Environments

    Get PDF
    Specialised and high priced simulators for surgical training, chemical labs, and flight training can provide real-world simulation in a safe and risk-free environment, but they are not accessible for the broader community due to costs for technology and availability of experts. Thus, training scenarios shifted to virtual worlds providing access for everyone interested in acquiring skills and knowledge at educational or professional institutions. Even in this context, we still expect a detailed formative feedback as would have been provided by a human trainer during the face to face process. Whilst the literature is focusing on goal-oriented assessment, it neglects the performed actions. In this paper, we present the Action-based Learning Assessment Method (ALAM) that analyses the action-sequences of the learners according to reference solutions by experts and automated formative feedback

    Augmented and mixed reality features and tools for remote laboratory experiment

    Augmented Reality (AR) is the process of overlaying meaningful interactive information in a live video stream for creating an enriched visual experience for users. Within Remote Access Laboratories (RAL) this enables users to gain design experience along with gaining knowledge about the particular experiment in question and potentially collaborate on design experiences. This paper focuses on the issues related to the applications of AR in RAL, the levels of AR in context of RAL and their effect on the learning tools. This paper also discusses the challenges of integrating a Natural User interface into the AR for RAL experiments. Finally it presets two example applications for AR in RAL experiment - Virtual Objects Creation and Object Identification and Tagging

    Trade-Off between Task Accuracy, Task Completion Time and Naturalness for Direct Object Manipulation in Virtual Reality

    Virtual reality devices are used for several application domains, such as medicine, entertainment, marketing and training. A handheld controller is the common interaction method for direct object manipulation in virtual reality environments. Using hands would be a straightforward way to directly manipulate objects in the virtual environment if hand-tracking technology were reliable enough. In recent comparison studies, hand-based systems compared unfavorably against the handheld controllers in task completion times and accuracy. In our controlled study, we com-pare these two interaction techniques with a new hybrid interaction technique which combines the controller tracking with hand gestures for a rigid object manipulation task. The results demonstrate that the hybrid interaction technique is the most preferred because it is intuitive, easy to use, fast, reliable and it provides haptic feedback resembling the real-world object grab. This suggests that there is a trade-off between naturalness, task accuracy and task completion time when using these direct manipulation interaction techniques, and participants prefer to use interaction techniques that provide a balance between these three factors.publishedVersionPeer reviewe

    Real-time hybrid cutting with dynamic fluid visualization for virtual surgery

    Get PDF
    It is widely accepted that a reform in medical teaching must be made to meet today's high volume training requirements. Virtual simulation offers a potential method of providing such trainings and some current medical training simulations integrate haptic and visual feedback to enhance procedure learning. The purpose of this project is to explore the capability of Virtual Reality (VR) technology to develop a training simulator for surgical cutting and bleeding in a general surgery

    Seeing Through The Kinect: A Survey On Heuristics For Building Natural User Interfaces Environments

    No full text
    The idea of interacting with technologies through touch-less and body-based interfaces has caused great excitement amongst users, but for the designers it has created various new challenges. Usability encompasses part of these challenges, and there have been attempts at creating heuristics for NUIs design. However, most of these heuristics consider using a device such as Kinect for the recognition of gestures, not people or objects. Therefore, in this paper we investigate the subject by presenting a systematic literature review aimed at finding heuristics for the design and evaluation of NUIs. Our analysis focuses on the scenario of helping people with visual disabilities in their daily activities. By looking at the state of the art, we intend to verify how many and which heuristics fit in this context. © 2014 Springer International Publishing.8513 LNCSPART 1407418Bailly, G., Müller, J., Lecolinet, E., Design and evaluation of finger-count interaction: Combining multitouch gestures and menus (2012) Int.
