Childhood obesity is a significant public health issue that can lead to a variety of physical and mental health implications. Serious games offer an innovative approach to address this challenge by reinforcing behaviors through interactive components. In this work, we explore the potential of serious games as a tool for facilitating behavior change in interventions to address childhood obesity.

Healthcare robotics needs context-aware policy-compliant reasoning to achieve safe human-agent collaboration. The current ontologies fail to provide healthcare-relevant information and flexible semantic enforcement systems. HERON represents a modular upper ontology which enables healthcare robotic systems to communicate and collaborate while ensuring safety during operations.

: This study investigates electrophysiological distinctions in auditory evoked potentials (AEPs) among individuals with chronic subjective tinnitus, with a specific focus on the impact of treatment response and tinnitus localisation. : Early AEPs, known as Auditory Brainstem Responses (ABR), and middle AEPs, termed Auditory Middle Latency Responses (AMLR), were analysed in tinnitus patients across four clinical centers in an attempt to verify increased neuronal activity, in accordance with the current tinnitus models. Our statistical analyses primarily focused on discrepancies in time-domain core features of ABR and AMLR signals, including amplitudes and latencies, concerning both treatment response and tinnitus laterality.

Article Synopsis
  • The study explored the use of the HOLOBalance platform, which employs augmented reality holograms for providing multisensory physiotherapy to older adults at risk of falls.
  • A pilot randomised controlled trial showed that the platform was safe, feasible, and well-accepted, with 69% of participants recommending it.
  • Participants demonstrated significant improvements in functional gait and balance (measured through FGA and Mini BESTest), outperforming the traditional OTAGO programme.

Mental fatigue during driving poses significant risks to road safety, necessitating accurate assessment methods to mitigate potential hazards. This study explores the impact of individual variability in brain networks on driving fatigue assessment, hypothesizing that subject-specific connectivity patterns play a pivotal role in understanding fatigue dynamics. By conducting a linear regression analysis of subject-specific brain networks in different frequency bands, this research aims to elucidate the relationships between frequency-specific connectivity patterns and driving fatigue.
