As ubiquitous media is developing rapidly, new HCI challenges emerge. In this paper, we address usability issues related to the transfer of content between fixed and mobile devices, as well as channel switching delays on mobile devices. We first provide an extensive review of the field. We then evaluate four relatively novel approaches for initiating a transfer of video content from a mobile ph...

This paper describes the software architecture of a distributed multi-people tracking algorithm for mobile platforms equipped with a RGBD sensor. Our approach features an efficient point cloud depth-based clustering, an HOG-like classification to robustly initialize a person tracking and a person classifier with online learning to drive data association. We explain in details how ROS functional...

This study examines some major variables moderating the relationships of service quality, customer satisfaction, and customer loyalty in mobile phone services. The study employed statistical analyses, such as reliability analysis, factor analysis, and hierarchical regression analysis. The results of the study reveal that service quality and customer satisfaction positively affect customer loyal...

We investigate how costly acquisition and exchange of customer-specific information affects industry profit and consumer welfare. Consumers differ in their preferences for competing brands and in their switching costs between brands. Brand-producing firms use their acquired knowledge of customer-specific preferences to differentiate prices. We show that consumers are worse off when firms acquir...

BACKGROUND In the last decade mobile telephone use has become more widespread among children. Concerns expressed about possible health risks have led to epidemiological studies investigating adverse health outcomes associated with mobile telephone use. Most epidemiological studies have relied on self reported questionnaire responses to determine individual exposure. We sought to validate the ac...

Current code division multiple access (CDMA) networks do not support soft handoffs between cell clusters serviced by different mobile switching centers (MSC’s). Three novel network configurations are proposed to overcome this limitation. Configurations I and II employ crosslinks to allow diversity combining of signals. This is accomplished in Configuration III by linking the modified MSC’s serv...

The implementation of a biped robot gait is a challenging task within the field of mobile robotics. Particularly, when the robot is subject to unknown disturbance in constantly changing terrain, a stable and robust gait is crucial. Regarding the machine together with the controller as an integrated system, the Dynamical Systems Approach yields a new perspective on legged robots. So called Limit...

A novel method for using an antenna array to improve the performance of the forward (base station to mobile) link in cellular mobile telecommunications systems is described. Previous methods usually involve either beamforming (forming narrow radiation patterns in the direction of the mobile) or spatial diversity (exploiting uncorrelated channels realized by placing antennas far apart in a fadin...

In this paper, we provide a dynamic graph theoretical framework for flocking in presence of multiple obstacles. In particular, we give formal definitions of nets and flocks as spatially induced graphs. We provide models of nets and flocks and discuss the realization/embedding issues related to structural nets and flocks. This allows task representation and execution for a network of agents call...

User’s continuance intention is vital to the future of mobile social apps (i.e. applications) with rapid development and intensive competitions among their providers. We draw on the theory of flow experience and switching cost to build an integrated model to explain factors influencing users’ continuance using intention. Our model is tested by survey and Structural Equation Model (SEM) in the m...
