Usability Design for Location Based Mobile Services in Wireless Metropolitan Networks
Inhaltsangabe:Abstract: The market of mobile technologies is growing at an enormous rate worldwide. With the latest developments in technology, new services are being invented which were not even possible some years ago. As new devices, applications and services emerge, also the number of mobile users is increasing in a rapid manner. Mobile broadband networks like UMTS, EDGE or Wireless LAN make it possible to reach a large group of users who gain access with their personal mobile devices, equipped with multimedia and data capabilities. Due to this development, new interesting possibilities arise for many areas. One of these areas is the tourism sector, which is being referred to in this thesis. The so-called m-tourism (mobile tourism) is an emerging field with an enormous marketing potential, as described in Chapter 2. Recent hardware inventions and developments are greatly pushing the market share. Companies are offering tailored products filling the needs of their customers. Personalization of services becomes a popular trend in this sector. But what do users think about such a mobile tourism service? Do they feel the service has added benefits, compared to traditional media and Web-based services? Are those products really user friendly? What would be the crucial applications and qualities that make the big difference ? A range of usability issues concerning mobile services is being discussed in the science community; are there already viable, good solutions? With the recent hype of so-called location based services, the consumer keeps calling for more usable products, featuring more intuitive interfaces. Others may fear being overwhelmed with features. Especially for the senior users, a relatively big target group for most mobile applications, these products often remain a mystery. Usability has been and should always remain a key element for quality software and successful applications. In this thesis, several applications are described, some of their user interfaces are analyzed and major flaws discovered. Furthermore, a corresponding prototype user interface is introduced with a specific analysis of each development step, taken from the book The Usability Engineering Lifecycle by Deborah J. Mayhew. Once prototypical realisations are available, users can validate the implemented approaches and evaluate concepts and realization details from their point of view. Such first user experiences are a valuable guidance for further [...]
Usability Design for Location Based Mobile Services in Wireless Metropolitan Networks
Today, mobility has become the key component of modern live, strongly driven by mobile connectivity via satellite communication, wireless networks, interactivity and mobile user devices. This huge networking potential offers the ground for numerous applications in almost every societal domain. Due to the novelty of most of these products and services, many of the current applications are yet experimental and exploratory in nature, and subject to permanent evaluation and improvement. As new devices, applications and services emerge, also the number of mobile users is increasing in a rapid manner. Mobile broadband networks like UMTS, EDGE or Wireless LAN make it possible to reach a critical mass of users who gain access with their personal mobile devices, equipped with multimedia and data capabilities. Due to this development, new interesting possibilities arise for many areas. One of these areas is the tourism sector, which is being referred to in this thesis. The broad range of the field calls for explicit design guidelines, providing the highest simplicity and ease of use to the future customer. Companies are offering tailored products filling the needs of their customers. Personalization becomes a popular trend in this sector. With the recent hype of so-called location based services, the consumer keeps calling for more usable products, featuring more intuitive interfaces. Others may fear being overwhelmed with features. Especially for the senior users, a relatively big target group for most mobile applications, these products often remain a miracle. As a sustained level of user satisfaction is critical for the outcome of new services and products, this study will evaluate existing applications, provide insight information into usability and demonstrate design evaluation strategies to successfully develop interactive mobile services.
Human-Computer Interaction. Interaction Design and Usability
Here is the first of a four-volume set that constitutes the refereed proceedings of the 12th International Conference on Human-Computer Interaction, HCII 2007, held in Beijing, China, jointly with eight other thematically similar conferences. It covers interaction design: theoretical issues, methods, techniques and practice; usability and evaluation methods and tools; understanding users and contexts of use; and models and patterns in HCI.
