Unobtrusive activity recognition is known to be the most preferred solution for monitoring daily activities of elderly people. In this paper, Scanpath Trend Analysis (STA) is employed for unobtrusive activity recognition of elderly people living alone. Binary sensor data are used and each activity is considered as a sequence of sensor points for this purpose. The real-world longterm fully annotated Aruba open dataset collected by binary sensors is used for the verification of accuracy and the efficacy of the proposed approach. With the STA, the F1-score of 0.758 is obtained, and furthermore, by adding some extra semantic information through an activity transition matrix, it is possible to have F1-score as 0.863. This F1-score is superior to all the related works that use binary sensor data for activity prediction, while computationally the approach presented is advantageous since long periods of training process can be avoided.

Sleep Quality Monitoring with Ambient and Mobile Sensing KAHVECİ, ali yavuz; Alemdar, Hande; ERSOY, CEM (2015-05-19) Evaluating daily life quality is important in ambient intelligence applications targeted for health status monitoring. When we consider the fact that people approximately spend one-third of their lives sleeping, we need to monitor the sleep quality as well as the activities of daily living in order to be able to provide a seamless health monitoring system. In this paper, a seamless activity recognition system that makes use of multi-modal wireless sensor networks (WSNs) and mobile phones is proposed. The pr...
Ubiquitous Cloud-based Monitoring via a Mobile App in Smartphones: An Overview Al-Turjman, Fadi; Betin Can, Aysu; Ever, Enver; Alturjman, Sinem (2016-11-20) The prevalence of wearable devices brought questions about their impact on user habits, use cases and future developments. Will users continue to use smart phones even if they have high capacity wearable devices? If that will be the case, for which reason people will continue to carry smartphones with them? User mobility and soft application usage correlation is an important research area for setting a base to answer these questions. In this literature review we focus on two subjects; smartphone usage patte...
Trends in Eye Tracking Scanpaths: Segmentation Effect? Eraslan, Sukru; Yesilada, Yeliz; Harper, Simon (2016-07-13) Eye tracking has been widely used to investigate user interactions with the Web to improve user experience. In our previous work, we developed an algorithm called Scanpath Trend Analysis (STA) that analyses eye movement sequences (i.e., scanpaths) of multiple users on a web page and identifies their most commonly followed path in terms of the visual elements of the page. These visual elements are mainly the segments of a page generated by automated segmentation approaches. In our previous work, we also show...
Design of fully integrated milliwatt thermoelectric energy harvesting interface circuit for wireless body sensor networks Demir, Süleyman Mahircan; Muhtaroğlu, Ali; Electrical and Electronics Engineering (2020-9) Wireless body sensor networks have drawn significant attention for providing out-of-hospital diagnosis and remote abnormality monitoring, which are vitally important for millions of people suffering from chronic diseases. Batteries powering these sensor networks hurt their mobility and longevity due to their bulkiness and down-time during charging or replacement. Therefore, this study focuses on thermoelectric energy harvesting from body heat, and targets eventual replacement of batteries by generating powe...
Multimodal Wireless Sensor Network-Based Ambient Assisted Living in Real Homes with Multiple Residents Tunca, Can; Alemdar, Hande; Ertan, Halil; Incel, Ozlem Durmaz; Ersoy, Cem (MDPI AG, 2014-06-01) Human activity recognition and behavior monitoring in a home setting using wireless sensor networks (WSNs) provide a great potential for ambient assisted living (AAL) applications, ranging from health and wellbeing monitoring to resource consumption monitoring. However, due to the limitations of the sensor devices, challenges in wireless communication and the challenges in processing large amounts of sensor data in order to recognize complex human activities, WSN-based AAL systems are not effectively integr...
