In early 2017, Cyclone Debbie caused widespread damage and disruption to electricity supply and other infrastructure in Queensland and New South Wales. This placed considerable strain on citizens and responders alike, as they sought to find ways to keep their mobile telephones charged. Despite the advance warning of the cyclone, news reports suggest that considerable portions of the population were...
In this paper, a planar 4-port antenna is designed to investigate the effect of user finger for mobile terminal application. The proposed array antenna covers a bandwidth of 2.5 GHz centered at 28 GHz. The effects of user's finger on the antenna are studied in four different positions on top of antenna elements, with six distances between antenna and user's finger. The losses due to the increased...
A major limitation of mobile Crowd Sourcing (CS) applications is the generation of false (or spam) contributions due to selfish and malicious behaviors of users, or wrong perception of an event. Such false contributions induce loss of revenue through disbursement of undue incentives and also negatively affects the application's operational reliability. In this work, we propose a reputation model,...
In recent years, service robots have advanced toward having to the ability to move autonomously in an environment in which they co-exist with humans. Thus, the robots must engage in obstacle avoidance to arrive at their goal point. In our previous research, we developed the artificial potential based method that the robot to plans an effective path simulating pedestrian characteristics by gently changing...
Resonant inductive coupling wireless power transfer (RIC-WPT) is attracting attention as a convenient power supply method to small mobile apparatus. The efficiency and the power transfer capability of RIC-WPT has been known to be profoundly dependent on the quality factor of the receiving resonator. However, the quality factor of the receiving resonator tends to be deteriorated because of the conduction...
Mobile medical applications are increasingly being used by patients and consumers. However, due to their complexity, these applications are normally only accessible to smartphone users. People using low-end cellphones cannot benefit from this new technology. The goal of this paper is to expand health service platform to lower-end cellphones, so that people in underdeveloped regions can benefit from...
A novel mobility-aware and energy-efficient coded caching provisioning strategy, Mobee, is proposed for a Cloud Radio Access Network (C-RAN). The placement of the Maximum-Distance Separable (MDS) encoded content at the Base Stations (BSs) is optimized to minimize the total energy consumption of the network comprising the transport and the caching energy consumptions. To account for user mobility,...
With the rising popularity of smartphones and the rapid growth of mobile applications, understanding the app usage behavior of mobile users is of growing importance for both app designers and service providers. Different from previous studies mining the correlation between apps and physical world factors, e.g. location, time, etc., in this paper we focus on the interdependency among apps and try to...
Data is becoming more and more valuable as technology advances. Through crowdsourcing organizations are able to collect large amounts of data at an effective rate with little cost. This paper proposes a crowdsourcing-based music playing system, where the next song to play is determined by the listening preferences of realtime online users. Unlike conventional radio play system, where songs are randomly...
Knowledge of people's transportation mode is important in many civilian areas, such as urban transportation planning. Current methodologies in collecting travelers' transportation modes are costly and inaccurate. The increasing sensing and computing capabilities of smartphones and their high penetration rate enable automatic transportation mode detection. This paper designs and implements a light-weight...
We designed, implemented, and evaluated a small physical keyboard, composed of four to five keys with a variety of mappings for the letters, along with one or two navigational function keys operated by the thumb. The small size allows it to be used for smartwatch text entry, and can be mounted on various body parts as a wearable keyboard. It is primarily used as an ambiguous keyboard, akin to T9,...
Classification of daily human movements using wearable sensor technology is among the current research topics, especially healthcare. In this study, eight different daily human movements (writing, walking, running, tooth brushing, writing on paper, using keyboard, stationary and cleaning) are classified by using data obtained from only smartwatch motion sensors (accelerometer and gyroscope). To compare...
Nowadays, Virtual Reality (VR) and Augmented Reality (AR) offer new and extend existing customer experience in web and mobile environment. VR has been practiced a good start with game applications. By increasing interaction with user or equipment motion, applications have been strongly continuing to produce and reach more user experience target. In this paper, we would like to announce and introduce...
The high reliance on the Internet observed recently makes the quests of mobile networks capacity demand and reliability crucial in mobile networks design and management. The next generation mobile networks is anticipated to address the problem of increasing capacity demand by employing various techniques such as Massive MIMO, Heterogeneous Networks (HetNets), and millimeter wave (mm-Wave). Nevertheless,...
Conversational agents are often used to perform tasks on smartphones, but existing conversational agents are limited in capabilities and lack of customizability. My work explores using the programming-by-demonstration approach to enable end users to program new tasks for conversational agents by demonstrating using the familiar graphical user interfaces of third-party apps. I propose to use a multi-modal...
With the rapid development of the business and the continuous improvement of the level in SGCC, the security research in the mobile field has been paid more and more attention. Although mobile work terminals can improve the efficiency of field operations, but a large number of mobile terminal access, leading to the terminal management difficult to increase, security has been greatly challenged. Therefore,...
The natural disasters affecting railway are characterized by universality, frequency and variety in china. These events can suddenly cause a greater negative impact on the order of rail transport organizations in a short time. The abnormal circumstances of network node or network range will pose a threat to the safety and efficiency of rail transport. On the basis of analyzing the causes of the problem...
With the development of cultural level, the traditional tourism has not meet the needs of the development of the people. The development of traditional tourist scenic areas has been affected by the technology and the cloud computing, so we need continuous innovation and development, it can bring the new experience of the tourist. In this paper, from the angle of tourist, scenic, government, we will...
Smartphones are a popular device class for mobile Augmented Reality but suffer from a limited input space. Around-device interaction techniques aim at extending this input space using various sensing modalities. In this paper we present our work towards extending the input area of mobile devices using front-facing device-centered cameras that capture reflections in the cornea. As current generation...
Human activity patterns such as communication and cooperation rely in large parts on smartphone-based interaction. Day-to-day available communication means are taken for granted. But in scenarios where communication infrastructure is broken, such as in the aftermath of a disaster, communication establishment becomes crucial. In those post-disaster conditions ubiquitous mobile devices carried by humans...
