Airwriting: a wearable handwriting recognition system
Personal Technologies - Tập 18 Số 1 - Trang 191-203 - 2014
We present a wearable input system which enables interaction through 3D handwriting recognition. Users can write text in the air as if they were using an imaginary blackboard. The handwriting gestures are captured wirelessly by motion sensors applying accelerometers and gyroscopes which are attached to the back of the hand. We propose a two-stage approach for spotting and recognition of handwritin...... hiện toàn bộ
‘That’s when I put it on’: stakeholder perspectives in large-scale remote health monitoring for older adults
Personal Technologies - Tập 27 - Trang 2193-2210 - 2023
Remote health monitoring (RHM) provides various benefits to older adults, but its use is still limited. Remote monitoring may help in avoiding emergencies and prolong users’ independence. To understand how to design systems which support older adults, we studied a large-scale remote health monitoring system. The system used fitness-grade smartwatches to monitor the vital signs of more than 2000 us...... hiện toàn bộ
Aspect ratio invariant visual cryptography by image filtering and resizing
Personal Technologies - Tập 17 - Trang 843-850 - 2012
In visual cryptographic scheme (VCS), each secret pixel is expanded to m subpixels in shadow images to encrypt a secret image. Apparently, we should put these m subpixels as a rectangle such that the blocks can be arranged compactly with each other. However, if the aspect ratio is viewed as important information of the secret image, the distortion occurs at the case that m is not a square. An aspe...... hiện toàn bộ

Prototypical implementation of location-aware services based on a middleware architecture for super-distributed RFID tag infrastructures
Personal Technologies - Tập 12 Số 2 - Trang 155-166 - 2008
We provide evidence of the feasibility and effectiveness of a middleware architecture for mobile devices (MoDs), which employs dense distributions of small computerized entities for providing fault-tolerant location-aware services. We do so by describing exemplary implementations based on radio frequency identification as an enabling technology. Firstly, we present prototypical implementations of ...... hiện toàn bộ
Service personalization for assistive living in a mobile ambient healthcare-networked environment
Personal Technologies - Tập 14 - Trang 575-590 - 2010
For more than a decade, it has been observed that due to the continuously increasing elderly population, medical expenditures for home health-care have rapidly increased every year. Health-care organizations are being encouraged to find more efficient methods of providing high-quality care with cost savings. Elderly people who live alone may fear being unable to obtain help if they are injured or ...... hiện toàn bộ
Mô hình nổi bật hình ảnh dựa trên dữ liệu theo dõi ánh mắt từ crowdsourcing và ứng dụng của nó trong thiết kế hình ảnh Dịch bởi AI
Personal Technologies - Tập 27 - Trang 613-630 - 2020
Các mô hình nổi bật hình ảnh dựa trên các đặc trưng cấp thấp của hình ảnh gặp phải vấn đề về độ chính xác và khả năng mở rộng thấp, trong khi các mô hình nổi bật hình ảnh dựa trên mạng nơ-ron sâu có thể cải thiện hiệu suất dự đoán một cách hiệu quả, nhưng yêu cầu một lượng lớn dữ liệu huấn luyện, chẳng hạn như dữ liệu theo dõi ánh mắt, để đạt được kết quả tốt. Tuy nhiên, phương pháp theo dõi ánh m...... hiện toàn bộ
Proxy-assisted access control scheme of cloud data for smart cities
Personal Technologies - Tập 21 - Trang 937-947 - 2017
Security and privacy for smart cities have attached much attention. As cloud computing can provide secure and reliable data storage and data sharing, it has become an important infrastructure for smart cities. However, in the cloud storage system, the cloud server cannot be fully trusted. Therefore, new solutions of access control of cloud data need to be proposed. In this paper, we construct a pr...... hiện toàn bộ
A file system for system programming in ubiquitous computing
Personal Technologies - Tập 11 - Trang 21-31 - 2005
In Ubiquitous computing, small embedded sensor and computing nodes are the main enabling technologies. System programming for such small embedded systems is a challenging task involving various hardware components with different characteristics. This paper presents a file system which organizes all computational and sensory functionality of a sensor node as resources in a uniform name space. It fu...... hiện toàn bộ
