In the present mobile climate, both companies as well as their consumers are able to execute various processes at any time in any location using a myriad of wireless technologies. Organizational trends demonstrate that mobile devices are being utilized exponentially more to solve problems from the strategic planning level to the operational level through various departments. This propensity was recently...
Context-aware and semantic-based technologies have been successfully employed to improve multimedia management in mobile environments. Large sets of context-tagged images on the Web are a concrete example of this achievement. The authors present two mobile systems, MMedia2U and CAPTAIN, that take the concept of context-aware multimedia management beyond photo organization and annotation. CAPTAIN is...
Utilizing mobile applications in the area of industrial field service promises several benefits, especially improved process support due to a tight integration of mobile workers and tailored information support. In this paper, we describe four mobile service business patterns derived from two industrial case studies. The first case study deals with the seamless integration of service engineers, while...
This paper introduces a hybrid recommendation platform providing information about tourist resources depending on the user profile, location, schedule and the amount of time for visiting interest points isolated or combined in a route.
In this paper, we propose a method to evaluate effectiveness of our proposed context-aware text entry by using Twitter. We focus on ”geo-tagged” public tweets because they include user's important contexts, real location and time. We also focus on TV program listing because 50% traffic of iPhone in Japan is generated from our home, in which I often tweets in watching a TV. Cyclical collecting system...
Tourism sciences represent a very active research field in Computer Science today. In particular, in the realm of ubiquitous computing. The evolution of mobile devices and their proliferation in society, the advancement of communication technologies and the trend toward creating hybrid spaces (symbiosis between nature and technology) will trigger a radical change in the way persons involved in mobility,...
Mobile phones are increasingly able to read auto-id labels, such as barcodes or RFID tags. As virtually all consumer products sold today are equipped with such a label, this opens the possibility for a wide range of novel digital services building on physical products. In this paper, we discuss the problems that arise when such novel applications are deployed, and present a unified system architecture...
The “Web of Things” vision promotes the integration of smart devices into web, using web technologies and protocols as underlying interaction mechanisms with smart devices. Technically many phones include various sensors and provide a large-scale sensing platform. To make this functionality available to a large number of (web) developers our research aims at easing the creation of applications that...
A novel method for quantitatively measuring social interactions on small temporal and spatial scales on the basis of interaction geometry (reduced to the parameters interpersonal distance and relative body orientation) with the help of infrared (IR) tracking is introduced. The method is intended to be used to establish a probabilistic classifier to identify existing social situations on the basis...
In developing countries, mobile devices can play an important role in delivering learning. But, poor information infrastructure and higher costs of mobile devices and connectivity restrict possibilities of providing successful mobile learning services. In the field of Information Communication for Development (ICT4D), this research aims to highlight the possible role of previously unexplored open...
The small form-factor of mobile handsets and the longer, variable latency of cellular networks are major hindrances to good user experience in mobile web related activities. Existing approaches have yet to adequately address the usability concerns caused by them. This paper describes the design and prototype implementation of MIntOS (Mobile Interaction Optimization System), a system for improving...
Web search providers have developed a highly successful business model, which has rendered them amongst some of the most profitable companies operating on the internet. Many observers regard mobile search as the next new big market. In contrast to search on PCs, however, the provision of search on mobiles is still in its infancy. In order to shed light on the real prospects of mobile search we performed...
Mobile devices that are capable of playing Internet videos have become wide-spread in recent years. Because of the enormous offer of video content, the lack of sufficient presentation space on the screen, and the laborious navigation on mobile devices, the video consumption process becomes more complicated for the end-user. To handle this problem, people need new instruments to assist with the hunting,...
Services have become increasingly important in today's Web-based applications. Users can access services in an anytime, anywhere manner using a wide variety of mobile devices. Mobile services are a key driver in today's telecommunication market, even though the potential of mobile services has not been fully exploited in existing telecommunication systems. A main driver in these markets are context-...
In the near future, the trend of user-generated content and services currently observable in the Internet domain will also affect the mobile environment: mobile users will become able to easily create content and small services while on the move and offer them to social communities. Mobile users will no longer be pure consumers, they will also become producers and providers of mobile content and services...
We build a Student-Partner mobile English learning system. We go deep into the campus to do English learning by portable of the mobile. The system offer the GPS function, campus map, camera, messaging, tracking and recording. Students can post the message or add the multimedia which he explore to the device. In the mobile, user can off-line to post the message. In addition, we design two activities,...
With the good customer foundation and increasing revenue, m-commerce is on the growing development stage. Although there are many literatures about the factors affecting customer intention in internet-based e-commerce contexts, it is necessary to do an empirical validation in m-commerce contexts. Factors of trust and social influence integrated to TAM were used in the conceptual model. Empirical data...
This article describes several technical aspects of mobile devices, sensor networks, web technologies, multimedia applications, and context sensitive services in information systems for museums developed at the author's university. Additionally, this paper describes several ideas and techniques of Green IT. It examines key features of the technologies and the systems, shows multiple methods of using...
Prefetching and Web caching have been known as techniques to increase the speed of Web loading process. Previous studies have been conducted to infuse artificial intelligence such as Artificial Neural Network (ANN) into Web caching. In this paper, we propose a new hybrid technique based on combination of ANN and Particle Swarm Optimization (PSO) for classification Web object either to cache or not...
This paper presents the background for and implementation of a mobile application complementing existing solutions within the fields of context-awareness, Web 2.0 and Personal Information Managers. Through description of application prototype and explanation of scenario model the paper presents how the application suggests one approach for creating meaningful content to mobile end users.
