... This design approach has been dictated by usability studies which have shown that a combination of summary and keywords of each document at first is more efficient in helping users locate relevant information from a list of documents than displaying entire documents directly [9]. Menus should be consistently designed to secure easy access to the desired information [12]. Menus and buttons are clearly labeled and consistent to help the user navigation, learnability and memorability. ...
This paper introduces an approach of enhancing the tourism experience by incorporating a tool that adopts a “web-to-mobile”
model into tourism websites that allows for the adaptation of personalized tourism web content to be transferred to a mobile
application hosted at users’ mobile device. These applications upon installation to mobile devices allow for browsing of adapted
multimedia content with no requirement for constant network connection. Furthermore so we convey the development experiences
of a multiplatform mobile tourist guide aimed at producing a personalized mobile guide application used in both an online
and offline modes offering services to tourists such as a personal profiling-based recommendation system, a commenting system
and location-based services. This paper focuses on the design, implementation and usability case study of a Multi-Platform
Tourist Guide system for the Municipal Council of Mytilene, Greece.
... Similarly, the third approach assumes some type of network connection and tracking systems (e.g., GPS or infrared beacons) to provide location-based services. Hence, whenever a user is out of coverage of the mobile network (i.e., ''has no signal'') he/she cannot access any service [16]. This article presents the analysis and design of a city tourist guide system and also its implementation in a prototype system, the myMytileneCity guide. ...
... In fact, mobile audio guides are being used in museum environments for years [15], while the use of personal digital assistants (PDAs) to enhance the museum visit experience has also been recently proposed [37]. Wireless access through mobile devices adds to the Internet connection the element of ''portability'', i.e., connection with no time or geographical limitations, by devices with high penetration to the public [16]; tourists are amongst this technology-oriented public. Hence, a growing body of commercial and research initiatives that incorporate electronic tourist guide functionality into mobile devices have been reported [34] . ...
... Most importantly, the download of new J2ME applications (jar files) is costly, slow and consumes network resources. With respect to the latter disadvantage, it is evident that J2ME- based mobile tourist guide applications should—ideally— be downloaded only once; synchronization with the backend server should thereafter be considered only when the user wishes to update the selected tourist content [16]. 5 A J2ME-based mobile tourist guide application: prototype implementation ...
Mobile tourism'' represents a relatively new trend in the field of tourism and involves the use of mobile devices as electronic tourist guides. While much of the underlying technology is already available, there are still open challenges with respect to design, usability, porta- bility, functionality and implementation aspects. Most existing ''mobile tourism'' solutions either represent of-the- shelf applications with rigidly defined content or involve portable devices with networking capabilities that access tourist content with the requirement of constant airtime, i.e., continuous wireless network coverage. This paper presents the design and implementation issues of a ''mobile tourism'' research prototype, which brings together the main assets of the two aforementioned approaches. Namely, it enables the creation of portable tourist appli- cations with rich content that matches user preferences. The users may download these personalized applications (optimized for their specific device's model) either directly to their mobile device or first to a PC and then to a mobile terminal (through infrared or bluetooth). Thereafter, net- work coverage is not further required as the applications execute in standalone mode and may be updated when the user returns online. The dynamically created tourist applications also incorporate a ''push model'', wherein new tourist content is forwarded to the mobile terminal with minimal user intervention as soon as it is added or updated by the administrator. Our prototype has been developed on the top of Java 2 Micro Edition (J2ME) which offers an ideal platform for the development of full-fledged, inter- active and portable applications tailored for resource- constrained mobile devices. The paper presents our development experiences with J2ME and highlights its main advantages and shortcomings in relation to the implementation of such kind of applications. Finally, an empirical evaluation of user experience with the mobile application prototype is presented.
... Not only are there usability issues when designing for mobile devices, like device capabilities, screen size and input methods [1]; one must take into account the compatibility issues of web platforms in comparison to mobile web platforms [16] and the cost of use of such technology for tourists [10]. The convergence of traditional web technology to mobile web technology is becoming an international reality [5]. It has been argued, the main reason behind the low impact of mobile web technology applications was the high cost which users bear when connecting to the mobile web [10]. ...
... A user can view Google maps via a PC web browser; however, Gmaps Java ME application should be installed to view Google maps via a mobile device [16]. Gmaps can be downloaded to a PC and the installed via cable, IR or Bluetooth to the phone or can be installed via WAP [5]. The tourist web site was implemented using JSP [9] / MySQL [12] web technologies and follows a 3-tier model, i.e. presentation -logic -database.Figure 1a, shows the website main screen page in the center there is a Ajax based map which show location markers of tourist content. ...
This paper introduces an approach of enhancing tourism web sites, giving the ability for such sites to be used as a tool to
allow tourists to tag content of choice for downloading and viewing on their own mobile device whilst on visit. Tourists,
upon installation to their mobile device, can view content material and a map of Mytilene (Lesvos, Greece) without the need
to “connect” to any mobile operator network, thereby saving high roaming charges. Our case-study has been the design and implementation
of a Multi-Platform Mobile Tourist Guide system for the Municipality of Mytilene (Greece), which uses a thin PC client via
Internet to present tourist content giving the user the opportunity to select content of choice and the ability to dynamically
build a thick client mobile tourist application or use the PDA Installation available at the Municipal tourist office.
... Since the open standard enables interoperability among products from different vendors, Wi-Fi products are proliferating through coffee houses, airport terminals, universities, and public libraries (Christensen, 2006). Wireless networking and computing not only enhance productivity for businesses but also expand the scope of public service and increase customer satisfaction (Intel, 2004;Gavalas and Economou, 2007). Additionally, key technological benefits of Wi-Fi networks include internet connections without serious deterioration in service quality at reasonable costs . ...
The City of Philadelphia adopted an ambitious broadband internet plan to provide the city with comprehensive wireless coverage. The decision to adopt this project involved a tradeoff between the benefit of high-speed service to all residents and cost of the project. The project represents breaking a relatively new ground, with few experiences of other government agencies to rely upon for guidance. This paper suggests the use of system dynamics modelling as a means to assess project risk and the result of the model simulation reveals the inherent risk of price manipulation by competitive service providers.

... "J2Me provides a vehicle for creating complex applications with a higher degree of interactivity compared to their (browser based) WAP or i-Mode counterparts. Independence ... from the underlying transport protocol is expected to lead to a synergy of the J2Me and WAP/i-Mode worlds" (Gavalas & Economou, 2007) The vital element of this project is that the user is part of the authentication process. It will be necessary to justify self-authentication and in doing so there is a need to re-examine the philosophical issues and practical issues. ...
... Wireless Access Protocol (WAP) according toB"Far (2005),Gavalas and Economou (2007) is the single most pervasive framework used for building most mobile applications available today.WAP was originally founded by Nokia, Ericsson, Motorola and Unwired Planet in 1997 (Orange). The WAP 1.0 stack was designed with low bandwidth mobile connections in mind and supports its own Wireless Mark-up Language (WML) it is independent of the underlying Mobile network technology. ...
YATIRI is the Tourist Information Platform of region Puno for mobile devices, which provides timely and updated information about the tourist attractions of the region Puno, for local and foreign tourists who visit this tourism destiny. This information is shown on mobile devices (mobile phone, smartphone, Tablets, PDAs, etc.), instead of the classical manuals and printed paper tourism guides (Handbooks). The developed platform takes advantage of the latest technological features in mobile devices, offering an application rich in content, which can run on the most used platforms like: Android, iOS, BlackBerry, Windows Phone and Java Micro Edition (JME). The application doesn't need an internet connection. Once it's installed on your cellphone or mobile device the user can access, anywhere, to the information from the tourist attractions of the region Puno.
The website has been greatly extended and is popular all over the world for electronic commerce. Many technical tools and business functions can increase their reach by websites. The mobile phone service is an essential amenity for people. The intention of this research is to take an extensive look at different kinds of mobile phone website users. In this research, Q methodology is used to gather and analyze the data. According to the results, users’ types may be categorized into four groups: Online shoppers, Information seekers, Recreation demanders, and Easy users. The empirical results of this study can provide decision support intelligence for the websites designers to increase mobile phone website users’ satisfaction.
While the use of mobile Web contents has shown a considerable increase, most of these contents, which are written in HTML format, are not convenient enough to use. Even though rich user-interfaces can be developed using some technologies like Flash Lite, it costs high because developers need to construct a whole application from scratch. Therefore, the development framework for mobile Web contents which reduces the development cost is needed. In this paper, we propose a development framework for rich user-interfaces of mobile Web contents. The proposed framework employs the dependency injection pattern to separate a content and its user-interface. Each user-interface component provides a functionality of a specific user-interface, and information that is specific to a particular website is described in an HTML document. A Web site is made by binding multiple user-interface components with an HTML document. The proposed framework provides a reduction of the development cost of mobile Web sites with a rich user-interface by leveraging existing resources.
The purpose of this research is to construct the digital capital measures of mobile phone service websites. An in-depth interview is used to collect data. Content analysis and Analytic Hierarchy Process are employed to analyse data. According to the results, the digital capital is categorised into four dimensions: internet relational capital, internet customer capital, internet innovative capital and internet service capital. The research also develops 17 indicators for digital capital assessment. Measuring digital capital can be used to improve and formulate mobile phone websites service quality and provide evaluation indicators for websites managers.
