Abstract
The study of ambient movement guidance encompasses a multidisciplinary approach to facilitating and guiding individuals, particularly older adults, within their living environments. This involves integration of ambient sensors, such as motion detectors, cameras, or IoT devices, to monitor the movements and activities of individuals in real time. By leveraging these sensors, the system can predict and anticipate the expected movements of the person, allowing for proactive ambient guidance and support. In addition to ambient guidance, robots can also play a role in leading individuals by interfacing through audio prompts or visual cues through their daily activities. However, despite advancements in sensor technology and robotic assistance, uncertainties persist in the monitoring and prediction of movements. These uncertainties can arise from various sources, including sensor noise, occlusions, environmental changes, and inherent variability in human behavior. Addressing these uncertainties requires probabilistic modeling techniques based on partially observable hidden Markov models (POHMMs) and various of its extensions such as POMDP, to effectively capture the dynamic nature of movement patterns and incorporate uncertainty into the decision-making process. This paper presents a detailed overview study of probabilistic framework and how its various interpretation can be used in developing an ambient movement guiding system for supporting individuals, particularly older, in support of ageing-in-place paradigms.
期刊介绍:
The overall aim of the International Journal of Telemedicine and Applications is to bring together science and applications of medical practice and medical care at a distance as well as their supporting technologies such as, computing, communications, and networking technologies with emphasis on telemedicine techniques and telemedicine applications. It is directed at practicing engineers, academic researchers, as well as doctors, nurses, etc. Telemedicine is an information technology that enables doctors to perform medical consultations, diagnoses, and treatments, as well as medical education, away from patients. For example, doctors can remotely examine patients via remote viewing monitors and sound devices, and/or sampling physiological data using telecommunication. Telemedicine technology is applied to areas of emergency healthcare, videoconsulting, telecardiology, telepathology, teledermatology, teleophthalmology, teleoncology, telepsychiatry, teledentistry, etc. International Journal of Telemedicine and Applications will highlight the continued growth and new challenges in telemedicine, applications, and their supporting technologies, for both application development and basic research. Papers should emphasize original results or case studies relating to the theory and/or applications of telemedicine. Tutorial papers, especially those emphasizing multidisciplinary views of telemedicine, are also welcome. International Journal of Telemedicine and Applications employs a paperless, electronic submission and evaluation system to promote a rapid turnaround in the peer-review process.
