Delivery of Personalized and Adaptive Content to Mobile Devices:A Framework and Enabling Technology

Many innovative wireless applications that aim to provide mobile information access are emerging. Since people have different information needs and preferences, one of the challenges for mobile information systems is to take advantage of the convenience of handheld devices and provide personalized information to the right person in a preferred format. However, the unique features of wireless networks and mobile devices pose challenges to personalized mobile content delivery. This paper proposes a generic framework for delivering personalized and adaptive content to mobile users. It introduces a variety of enabling technologies and highlights important issues in this area. The framework can be applied to many applications such as mobile commerce and context-aware mobile services

Interface Design for Mobile Applications

Interface design is arguably one of the most important issues in the development of mobile applications. Mobile users often suffer from the poor interface design that seriously hinders the usability of those mobile applications. The major challenge in the interface design of mobile applications is caused by the unique features of mobile devices, such as small screen size, low resolution, and inefficient data entry methods. Therefore, there is a pressing need of theoretical frameworks or guidelines for designing effective and user-friendly interfaces for mobile applications. Based on a comprehensive literature review, this paper proposes a novel framework for the design of effective mobile interfaces. This framework consists of four major components, namely information presentation, data entry methods, mobile users, and context. We also provide a set of practical interface design guidelines and some insights into what factors should be taken into consideration while designing interfaces for mobile applications

Intended Deception in the Virtual World

This study explores how people intend to deceive in the virtual world. Previous research has focused the intent and behavior of online deception, but has rarely looked into specific aspects of online deception including strategy, magnitude, and seriousness. We answered research questions about people’s selection of deception strategies, perceived seriousness of deception, and magnitude of deception in the virtual world via a survey study. Additionally, we examined possible influence of age and gender on deception. The findings are interesting and offer implications for designing deception detection strategies

Developing Adaptive and Personalized Mobile Applications: A Framework and Design Issues

The rapid growth of mobile technology has expedited ubiquitous information access via handheld devices. However, the fundamental natures of mobile information systems are different from those of desktop applications in terms of purpose of use, device features, communication networks, and working environments. This poses various challenges to mobile information systems on how to deliver and present multimedia content in an effective and adaptive manner. One of the major challenges is to deliver personalized information to the right person in a preferred format based on the changing environment. This paper proposes an innovative framework for developing mobile applications that deliver personalized, context-aware, and adaptive content to mobile users. The framework consists of four major components: information selection, content analysis, media transcoding, and customized presentation. It can be applied to a variety of mobile applications such as mobile web, news alert services, and mobile commerce

Understanding Patients’ Compliance Behavior in a Mobile Healthcare System: The Role of Trust and Planned Behavior

The ultimate goal of any prescribed medical therapy is to achieve desired outcomes for patients. However, patient non-compliance has long been a major problem detrimental to patients’ health and thus is a concern of all healthcare providers. Patient trust in doctors and patient-doctor communication have been identified as critical factors influencing patient compliance. Nevertheless, little is known about the role of mobile technologies in patient compliance. The purpose of this paper is to predict and empirically demonstrate how mobile healthcare applications juxtaposed to patient trust can increase patients’ compliance. We conducted a field survey with 125 patients in the United States. PLS techniques were employed to analyze our dataset. The results reveal that patient-doctor communication and the use of mobile system significantly impact patients’ trust, which has a prominent effect on patient compliance attitude. We also find that behavioral intention, response efficacy, and self-efficacy positively influence patients’ actual compliance behavior

A Single-Handed Partial Zooming Technique for Touch-Screen Mobile Devices

Despite its ubiquitous use, the pinch zooming technique is not effective for one-handed interaction. We propose ContextZoom, a novel technique for single-handed zooming on touch-screen mobile devices. It allows users to specify any place on a device screen as the zooming center to ensure that the intended zooming target is always visible on the screen after zooming. ContextZoom supports zooming in/out a portion of a viewport, and provides a quick switch between the partial and whole viewports. We conducted an empirical evaluation of ContextZoom through a controlled lab experiment to compare ContextZoom and the Google maps’ single-handed zooming technique. Results show that ContextZoom outperforms the latter in task completion time and the number of discrete actions taken. Participants also reported higher levels of perceived effectiveness and overall satisfaction with ContextZoom than with the Google maps’ single-handed zooming technique, as well as a similar level of perceived ease of use

User-Centered Context-Aware Mobile Applications―The Next Generation of Personal Mobile Computing

Context-aware mobile applications are systems that can sense clues about the situational environment and enable appropriate mechanisms of interaction between end users and systems, making mobile devices more intelligent, adaptive, and personalized. In order to better understand such systems and the potentials and barriers of their development and practical use, this paper provides a state-of-the-art overview of this emerging field. Unlike previous literature reviews that mainly focus on technological aspects of such systems, we examine this field mainly from application and research methodology perspectives. We will present major types of current context-aware mobile applications, and discuss research methodologies used in existing studies and their limitations, and highlight potential future research
