This article describes a developed interactive environment (based on "dashboards") allowing the geriatricians and caregivers to access, analyze and precisely annotate or label specific granular cases of interest in a variety of heterogeneous data collected to identify behaviour changes through Smart City IoT and Open Data infrastructure. The overall goal is to detect and contextualize as...
This paper describes ongoing work in analyzing sensor data logged in the homes of seniors. An estimation of relative energy expenditure is computed using motion density from passive infrared motion sensors mounted in the environment. We introduce a new algorithm for detecting visitors in the home using motion sensor data and a set of fuzzy rules. The visitor algorithm, as well as a previous algorithm...
Due to home accidents occurring within the world's aging population, especially with the accidental stumble and falling of the elderly, mortality and morbidity from falls have become one of the major issues in the health care system. In most developed countries, most frequent stumbles and falls occur in and around the community or at home. A number of wearable devices integrated with accelerometers...
Changing demographics in the western society require the provision of resources to enable independent living for the aging population. This includes guiding research and development into technologies and interventions that would assist the elderly to live safely and independently in their own homes. It is also essential that policy regarding privacy and security is addressed, both on a regional, national...
Supporting ageing in place and staying at home, delaying institutionalization, lightening the caregivers' burden, improving the elderly quality of life are as many expectations that TeleHealthCare aims at coming up to. This paper proposes a method for Telemonitoring to detect abnormal changes in behavior which may lead to an early entrance in dependency. This method allows to detect and quantify a...
We investigated age-related changes in the semantic distance between successively generated words in two letter fluency tasks differing with respect to demands placed on executive control. The semantic distance was measured by Latent Semantic Analysis (LSA). The results show that older people have a larger semantic distance between successively generated items than young people, and that this effect...
This paper describes ongoing work in analyzing sensor data logged in the homes of seniors. A visualization of motion sensor data in the form of a density map which uses different colors to show levels of activity was introduced previously. For evaluating changes in activity level and periodicity of life style, we introduce a dissimilarity measurement of density maps based on co-occurrence matrices...
This study aims to explore the concepts of independence and shared decision making in the context of smart home technologies for older adults. We conducted a Delphi study with three rounds involving smart home designers, and researchers as well as community dwelling older adults. While there were differences in the way different stakeholders define these concepts, the study findings provide clear...
In order to develop a monitoring system for a single aged person by grasping his or her usage of electricity, we developed a method to infer whether residents have independently operated electric appliances or not from total load current of the household.
Evaluation of cognitive function is an important tool in clinical care. A novel method of cognitive monitoring is proposed, whereby subjects complete three sessions of the popular past-time Sudoku while EEG is recorded. Data epochs surrounding a correct solution are extracted and compared to a resting condition. Mean EEG amplitude in the alpha and theta bands are examined by means of the temporal...
As we observe society in our days, we can see that people live longer; this means that we have an older population. As we know, elder are more likely to have health issues. The special needs presented by elder are gaining a major concern from all of us. Another tendency of our society is the lack of time that people demonstrate and, as a consequence, the lack of time reflects when families can't take...
Western societies are aging rapidly. An automated 24/7 surveillance to ensure safety of the elderly while respecting privacy becomes a major challenge. At the same time this is representative of novel and emerging video surveillance applications discovered lately besides the classic surveillance protection applications in airports, government buildings, and industrial plants. Three problems of current...
Movement in bed-placed pressure arrays often interferes with measurements. A method for automatically determining movement onset times from a bed-based pressure sensor array is proposed. By using control levels based on a moving average and the moving variance, the method can adapt to changing positions and postures of the bed occupant. A simulation was performed on a generated 24-hour pressure signal...
