Rätz, R. (author), Ratschat, A.L. (author), Cividanes Garcia, N. (author), Ribbers, G.M. (author), Marchal Crespo, L. (author)In stroke rehabilitation, simple robotic devices hold the potential to increase the training dosage in group therapies and to enable continued therapy at home after hospital discharge. However, we identified a lack of portable and cost-effective devices that not only focus on improving motor functions but also address sensory deficits. Thus, we...journal article 2024

Abdelgawad, Ahmed A. (author), Comes, M. (author)Evaluation and testing are significant steps in developing any information system. More attention must be devoted to these steps if the system is to be used in high-risk contexts, such as the response to conflict disasters. Several testing methodologies are designed to guarantee that software fulfills technology requirements; others will assure...book chapter 2023

Cardaioli, Matteo (author), Conti, M. (author), Orazi, Gabriele (author), Tricomi, Pier Paolo (author), Tsudik, Gene (author)Authentication and de-authentication phases should occur at the beginning and end of secure user sessions, respectively. A secure session requires the user to pass the former, but the latter is often underestimated or ignored. Unattended or dangling sessions expose users to well-known Lunchtime Attacks. To mitigate this threat, researchers...journal article 2023

While the user must pass the former to start a secure session, the latter's importance is often ignored or underestimated. Dangling or unattended sessions expose users to well-known Lunchtime Attacks. To mitigate this threat, the...conference paper 2022

(author)Humans are embarking on a new era of space exploration with the plan of sending crewed spacecraft to the Moon, Mars, and beyond. Extravehicular activities (EVAs) will be an essential part of the scientific activities to be carried out in these missions, and they will involve extensive geological fieldwork. These EVAs entail many challenges as...journal article 2022

(author)Non-profit organisations (NPOs) are one type of open data intermediaries connecting different actors in the open data ecosystem. They perform a number of activities, from requesting the government to open up the data to application development. Such activities can have an effect on open data usability barriers that other actors in the open data...conference paper 2022

Wenk, Nicolas (author), Buetler, Karin A. (author), Penalver-Andres, Joaquin (author), Müri, René M. (author), Marchal Crespo, L. (author)Background: The relearning of movements after brain injury can be optimized by providing intensive, meaningful, and motivating training using virtual reality (VR). However, most current solutions use two-dimensional (2D) screens, where patients interact via symbolic representations of their limbs (e.g., a cursor). These 2D screens lack depth...journal article 2022

However, in current VR-based motor training, movements of the users performed in a three-dimensional space are usually visualized on computer screens, televisions, or projection systems, which lack depth cues (2D screen), and...journal article 2021

Li, Wenting (author), Cheng, Haibo (author), Wang, Ping (author), Liang, K. (author)Multi-factor authentication (MFA) has been widely used to safeguard high-value assets. Unlike single-factor authentication (e.g., password-only login), t-factor authentication (tFA) requires a user always to carry and present t specified factors so as to strengthen the security of login. Nevertheless, this may restrict user experience in...journal article 2021

van Oosterom, P.J.M. (author), de Vries, M.E. (author), Cemellini, Barbara (author), Thompson, R.J. (author)The visualization of cadastral parcels in 3D is a challenge, since legal boundaries are, in many cases, invisible in the real world; so how can we properly represent something that is not visible to our eyes? This paper uses the results from research looking into problems of occlusion and ambiguous perception (in terms of position, size and...conference paper 2019
