Sustaining lower limb functionality is extremely important in the preventative care of the elderly. Chair exercise, in which the exerciser sits on an ordinary chair, offers a way for seniors with little physical strength to exercise without a great deal of effort. Meanwhile, Microsoft's Kinect sensor that is capable of detecting human motion without the subject having to wear any kind of a special...
In this paper, we propose a new method of highly-accurate mobile phone tracking using infrastructure-based laser-tracking sensors called laser-range scanners (LRS) and pedestrian DR (PDR) on the mobile phones. Each mobile phone continuously obtains readings from accelerometers and gyro sensors to detect moving distance and direction change (PDR information), while the phone user is accurately tracked...
This paper proposes a system for facilitating a smooth communication in the first meeting by using Augmented Reality (AR). "Go-kon" means a traditional style of a match-making party in Japan. It is one of typical situation that requires higher communication skill to all the participants. Against this problem, our system tries to minimize the communication difficulties that arise from the...
Compared with traditional Wireless Sensor Networks (WSNs), designing a routing protocol in Cognitive Radio Ad Hoc Networks (CRAHNs) is more difficult since issues such as the primary user (PU) occupancy problem and the multichannel rendezvous problem must be solved. Any path Routing, a kind of schemes that enables dynamic forwarder selection, seems to be a possible solution to the PU occupancy problem...
The recent increase in number of household appliances has resulted in an increase in the number of required remote controls. Multifunctional learning remote controls attempt to reduce the number of controls, but their complexity may confuse users. Recently, an alternative gesture-based control system has also been proposed, but it requires users to perform complicated gestures for turning on or selecting...
Activity recognition is of great importance for a variety of context-aware applications and especially for assistance provided for independent living of the elderly. One of the factors that has impact on the activity recognition accuracy is feature representation. Many approaches have been proposed to select the most discriminative subset of features for activity recognition, but they are data-dependent...
With the widespread use of smart phones, opportunistic networks that leverage opportunistic contacting and data transmission among people have become a new data sharing medium. In this paper, we propose an intelligent music sharing system called "Music On Go", which is based on mobility prediction and preference extraction in opportunistic networks. In detail, we first present a human mobility...
When we seek to protect and store a large number of collections of the treasures, its display in an exhibition cabinet needs to follow certain principles. Once their positions are determined, the big changes is not allowed. To determine whether a treasure is in the right place of a showcase or has been moved is a fundamental task for intelligent treasure protection and management system. Recently,...
This paper introduces a novel idea of analyzing logs of "working support through first person vision (FPV) communication", a working style in which a worker with a head-mounted camera works under the guidance of an experienced mentor monitoring the FPV at a distance. The logs contain various types of multimodal interactions concerning intentions, instructions, and explanations as well as...
Many lightweight installations of smart environment systems do not have complex and expensive sensing and actuating capabilities, leaving parts of the environment unobservable to the system. This limits reasoning and decision making complexity of such systems. A decision support system that can collaborate with human users alleviates this problem by asking users to provide missing pieces of information...
With the surge of varied crowd sensing systems, active user participation becomes a crucial factor that determines whether a crowd sensing system can provide good service quality. To encourage user participation in mobile crowd sensing, we propose a novel incentive mechanism called CSII -- a Cross-Space, multi-Interaction-based Incentive mechanism. CSII can estimate the value of a task based on the...
A fundamental problem in structured overlays is how to reflect the physical environment when nodes forward messages based on logical positions, independent of physical machines and physical network components. If the number of node groups that forward messages is reduced, costs are reduced for the entire network. However, when designing such an efficient algorithm, the characteristics of existing...
Recently the social question/answering systems have become a natural way for people to get information from their social connections. Despite its popularity in knowledge sharing, its development still faces several challenges, among which a notable one is that a majority of questions get no response. How to improve the response ratio and reduce the number of unanswered social questions has become...
Public datasets are becoming more and more available for organizations. Both public and private data can be used to drive innovations and new solutions to various problems. The Internet of Things (IoT) and Open Data are particularly promising in real time predictive data analytics for effective decision support. The main challenge in this context is the dynamic selection of open data and IoT sources...
Spatial crowd sourcing uses workers for performing tasks that require travel to different locations in the physical world. This paper considers the online spatial task assignment problem. In this problem, spatial tasks arrive in an online manner and an appropriate worker must be assigned to each task. However, outcome of an assignment is stochastic since the worker can choose to accept or reject the...
Palantir is a real-time collaboration system that is designed for people who glean information from Twitter during an event, and would like to consolidate Tweets into stories as and when they happen. The system is designed to easily let people share annotated Tweets from mobile clients, and use a web client to track Tweets, and consolidate these Tweets into stories that can later be published.
With the wide adoption of intelligent mobile phone with global positioning functionalities, location based services (LBS) are more and more popular. Location privacy becomes an important issue. The current methods on privacy protection can be classified into the following folds: privacy preserving LBS query in a real time manner, privacy protection on historical trajectory data publication afterwards...
The quick evolution of sensors and the broad scale utilization of pervasive devices have awashed ubiquitous systems with an unprecedented amount of sensor data. Inferring activity or context from sensor data has fueled enormous research interests. In this paper, we propose a novel predictive model that utilizes wavelets, voronoi regions and Conditional Random Fields (CRF) to predict activities from...
Despite the great demand on and attempts at package express shipping services such as the same-day delivery feasible for online firms, turning a profit is still difficult. To develop more economical or even cost-free transportation of packages, in this paper, we propose to make use of the existing taxis on the street that are delivering passengers, in a crowd-sourced manner. To the best of our knowledge,...
To improve user experience, reducing energy consumption of a wireless device is an important factor. Several smartphones try to save energy by tearing down connections to the mobile network as soon as the data transmission has completed. However, the side effect is the frequent connection reestablishment in applications where small amounts data are sent and received, leading to a high energy overhead...
