COSAR: hybrid reasoning for context-aware activity recognitionPersonal Technologies - Tập 15 Số 3 - Trang 271-289 - 2011
Riboni, Daniele, Bettini, Claudio
Human activity recognition is a challenging problem for context-aware systems
and applications. Research in this field has mainly adopted techniques based on
supervised learning algorithms, but these systems suffer from scalability issues
with respect to the number of considered activities and contextual data. In this
paper, we propose a solution based on the use of ontologies and ontological

Automatic identification method for driving risk status based on multi-sensor dataPersonal Technologies - - 2021
Lixin Yan, Yike Gong, Zhijun Chen, Zhenyun Li, Junhua Guo
Real risk status detection is an effective way to reflect risky or dangerous
driving behaviors and therefore to prevent road traffic accidents. However, a
driver’s risk status is not only difficult to define but also uncontrollable and
uncertain. In this study, a simulated experiment with 30 drivers was conducted
using a driving simulator to collect the multi-sensor data of road conditions,
humans... hiện toàn bộ

Ubiquitous computing has shown promise in applications for health care in the
home. In this paper, we focus on a study of how a particular ubicomp capability,
selective archiving, can be used to support behavioral health research and
practice. Selective archiving technology, which allows the capture of a window
of data prior to and after an event, can enable parents of children with autism
and rel... hiện toàn bộ
BHE-AC: a blockchain-based high-efficiency access control framework for Internet of ThingsPersonal Technologies - Tập 26 - Trang 971-982 - 2021
Baobao Chai, Biwei Yan, Jiguo Yu, Guijuan Wang
In this information age, with the emergence of organizations, the number of
various resources on the Internet of Things is also increasing. Generally,
different users have different access permissions to different resources and
most of the existing schemes have realized access control. But most of them are
rough and not feasible in many organizations. Moreover, traditional access
control schemes a... hiện toàn bộ
Developing technology for autism: an interdisciplinary approachPersonal Technologies - Tập 16 - Trang 117-127 - 2011

We present an interdisciplinary methodology for designing interactive
multi-modal technology for young children with autism spectrum disorders (ASDs).
In line with many other researchers in the field, we believe that the key to
developing technology in this context is to embrace perspectives from diverse
disciplines to arrive at a methodology that delivers satisfactory outcomes for
all stakeholder... hiện toàn bộ

Recently, social networks have become the most prevalent IT paradigm, as the
vast majority of Internet users maintain one or multiple social networking
accounts. These accounts, irrespectively of the underlying service, contain rich
information and data for the owner’s preferences, social skills, everyday
activities, beliefs and interests. Along with these services, the computation,
sensing and ne... hiện toàn bộ
