Abstract: Some forces in nature are difficult to comprehend due to their non-intuitive and abstract nature. Forces driving gyroscopic precession are invisible, yet their effect is very important in a variety of applications, from space navigation to motion tracking. Current technological advancements in haptic interfaces, enables development of revolutionary user interfaces, combining multiple modalities: tactile, visual and auditory. Tactile augmented user interfaces have been deployed in a variety of areas, from surgical training to elementary education. This research provides an overview of haptic user interfaces in higher education, and presents the development and assessment of a haptic-user interface that supports the learner’s understanding of gyroscopic precession forces. The visual-haptic simulator proposed, is one module from a series of simulators targeted at complex concept representation, using multimodal user interfaces. Various higher education domains, from classical physics to mechanical engineering, will benefit from the mainstream adoption of multimodal interfaces for hands-on training and content delivery. Experimental results are promising, and underline the valuable impact that haptic user interfaces have on enabling abstract concepts understanding, through kinesthetic learning and hands-on practice.

Keywords: Haptics, Force Feedback, Gyroscope, Precession, Computer-based Simulation.

Abstract: One of the fields in which human-machine interaction is more and more relevant is medicine, especially because, in this area, a specialized digital system has better chances of detecting illnesses, injuries or other significant aspects, than human perception. This paper proposes an experimental solution, designed to help guide electrocardiography (ECG) sensor placement on a patient. At the core of the solution is a Microsoft Kinect camera, providing both color and depth information that is used for generating a cyber representation of the patient’s skeleton. Electrode placement locations are calculated and then overlaid on an RGB image, so the user has real-time feedback for correctly placing the sensors. The purpose of this solution is to contribute to the process of assistive ECG measurements, enabling home treated patients, students and doctors to experiment guided measurements procedures without the need of specialized medical assistance or second opinion confirmation.

Keywords: eHealth, Kinect, heart activity, ECG, human-machine interaction.

Abstract: The study presents the research outcomes regarding the attitude of the students from Timişoara, from humanities and technical specializations, toward the emergence and development of artificial intelligence (AI). How will new technologies transform our lives? Will our workplaces be affected by the emergence and development of AI entities? Will the use of material resources be optimized? Will people's comfort increase? These are just some of the questions we are trying to answer, highlighting the students' attitude at the universities of Timişoara regarding the emergence of artificial intelligence, with emphasis being placed on the most likely consequences of its future development, the benefits that its development would entail. The method used for data collection was the sociological survey and the information gathering tool was the questionnaire, applied online to 928 people. The variables according to which the data were interpreted were the type of specialization (humanistic and technical) and the gender of the respondents (male and female). In general, positive perceptions about the emergence and development of artificial intelligence entities/ devices were recorded , the benefits that it could bring in the future by building sophisticated robots, surpassing human intelligence, the control of intelligent weapons by humans, the emergence of new trades, the improvement of health care and human health, the optimization of material resources, and so on.

Keywords: artificial intelligence, advantages, benefits, perceptions.

Abstract: In the last years, there is a growing interest in the usability of software applications for medical care. A typical category of patients that need support for the self-management of medication and life style are the diabetics. This paper aims to present an empirical study of usability evaluation of three mobile-based applications for diabetes care and a comparative analysis of the identified usability problems. The evaluation results revealed several usability problems that are mainly related to the user guidance, user support and user effort.

Keywords: Usability, usability inspection, usability heuristics, diabetes care, online medical centers.
