陈天桥为何成首富

31岁的陈天桥走上中国首富的位置绝对不是偶然,在他身后,是那个塑造了中国网络游戏传奇的盛大公司。新兴互联网企业终于第一次从财富上战胜了老牌互联网企业。想起了方兴东发表的《中国互联网面临“变天”———盛大何时超越新浪?》一文,他认为中国互联网媒体特性主导的“门户时代”面临终结,一个全新的围绕网民个性化服务的“服务时代”正在开启。虽然“服务时代”这个概念被普遍认为评价不准,但是对于他的部分观点,还是得到了大多数人的认同。陈天桥上周取代丁磊成为新的中国首富或许正验证了方兴东的部分说法。门户提供给大多数网民的是最一般的需求,新闻和信息等内容是排头兵,邮件和搜索是两大支撑,其它延伸和增殖服务是分支。在中国,新浪确立了门户的基本模式,也代表了当前在内容竞争方面的最高成就。但是,过去两年中国门户犯下战略性失误,由于短信短期盈利表现明显,大多数门户都忽略了其它业务的发展,而短信目前已经走到“穷途末路”,门户的盈利将大打折扣。其次,门户模式随着网民规模的不断扩大,总体网民的文化层次、经济条件和消费层次等的明显向下走而陷入了一种尴尬的境地———在“低级化”、“低俗化”和一些高端人群的需求间游离不定。其次,在门户不断向下走的时候,...

Anticipating information needs for senior portal contents

Many senior portals are expected to appear as the elderly population and the number of aged Internet users continues to increase. This study defines a senior portal as an Internet portal that is specific to seniors. The purpose of the study is to investigate what kind of content of senior portals is preferred by prospective users of senior portals, and to analyze the preference for contents. The study administered a survey to prospective senior portal users over 50 years of age who are residing in two large cities in Korea. This study found that content preferences vary according to the individual characteristics of prospective users. The findings of this study could help organizations to explore business opportunities, develop business models, and formulate business strategies that can differentiate them from their competitors.     

Designing accessible experiences for older users: user requirement analysis for a railway ticketing portal

This article presents the results of a survey that shows that older users differ in their attitude and experience towards the Internet not only according to their age or to their previous knowledge with Internet services, but also according to what they are expecting from this media. The aim of this study was to collect information about barriers on usage and perception of an online ticketing service for a nationwide public railway company, in order to enhance the notion of “accessibility” toward a broader understanding including non-technical accessibility factors as semantic accessibility and/or procedural accessibility. The results of the survey with 1,208 participants and additionally focus groups, interviews and qualitative analysis of user feedback indicate that in order to improve and optimize the usage of the online system for older adults, it is necessary to develop a system which is not only universally accessible, but also satisfies the specific expectations of senior users. This article concentrates on designing accessible user experiences and presents several recommendations to the area and for WCAG 2.0 according to the results.     

Introducing computers and the Internet to older users: findings from the Care OnLine project

This paper reports the findings from a two-year pilot project called Care OnLine (COL). The COL project has introduced computers and the Internet into the homes of 50 elderly and vulnerable volunteers and provided shared Internet access at five shared schemes housing older people across the Market Harbrorough district of Leicestershire. A specific web portal was designed that was geared towards older and vulnerable people and provided information about the different services available to them, as well as links to a variety of websites. All the volunteers were provided with training in using computers and the Internet, and were interviewed regarding their experiences. Findings related to their attitudes towards, and experiences of, computers and the Internet are reported. The impact of having access to computers and the Internet on the volunteers lives and some lessons learnt from providing such a scheme are also discussed.     

The Internet: global information superhighway for the future

The information revolution is bringing people of different backgrounds from around the world into a global information superhighway. The Internet provides a global platform connecting thousands of networks around the world. There is a variety of information available on the Internet for the users. It has been considered as a forum for users to share worldwide information resources. The resources are so vast that many of us really cannot grasp or understand the Internet fully. It has become a ‘global information library’ which allows the users to participate in the group discussion, search for any information, start any discussion with others and so on. It can be considered as a hybrid environment of postal services, citizen's band radio, libraries and neighborhood community centers where we (‘we’ is mainly used in this paper in its generic form) can spend time with our friends (‘our’ is also mainly used generically). Internet users (Internauts) share jokes, gossip in on-line conferences and join special groups to keep abreast of their specific interests. The main objective of this tutorial is to discuss various services on the Internet, their implementations, various Internet tools, and interconnection to the Internet. Other important issues like the Internet addressing, domain name system, IP addressing, etc. are discussed in detail in order to understand some design concepts. A brief list of the different types of browsers for different platforms is given. A discussion on future of the Internet is given via different advances and tools defined to provide security, interconnectivity and other related issues.     

Intelligent healthcare service based on context inference using smart device

In the field of “U-Healthcare Service”, many studies have been actively conducted to develop “smart device”-based healthcare applications that enable healthcare providers and patients to be better served through interoperations among various kinds of sensors and wireless network interfaces. In particular, contemporary intelligent healthcare services not only recognize users’ context information through smart devices, computers, and so forth, but also acquire information from heterogeneous sensors to achieve context-aware inference services. Among such information, the weather information is tightly related to diseases such as asthma and allergies. Therefore, there is a high demand for research to utilize the weather information for healthcare services. In this paper, we propose a context inference-based intelligent healthcare service that exploits both the weather conditions information and the diverse healthcare ontologies available on the Internet. The proposed service aims at modeling a context ontology in users’ healthcare service environment and defining the inference rules, thereby accomplishing a satisfactory real-time healthcare service.     

A study of the service quality of general portals

An Internet portal provides not only a linkage to Web sites but also an entry point to information services. To be successful, it needs to attract a large volume of visitors and consistently deliver a high level of service quality. However, we believe that the service quality of Internet portals, differentiated into business and general portals, should be measured by different instruments, as they are used for different purposes. We conducted two studies employing exploratory factor analysis and confirmatory factor analysis to identify an instrument to measure the service quality of general portals. The results indicated that the instrument is a four-factor model that includes adequacy of information, appearance, usability, and privacy and security. However, only the first two factors are significantly associated with customer satisfaction. Also, it was noted that Web page appearance was not significant for business portals but was for general portals.

The effects of zoomable user interfaces and user age in searching for a target with a mouse on a two-dimensional information space

A zoomable user interface (ZUI) is a useful function to help users deal with large information spaces displayed within a screen. Although used in many applications, ZUIs have not been sufficiently studied in terms of usability. Usability problems may be more crucial for older people than younger ones. The objective of this study is to examine the effects of a combination of two zoom factors (three zoom focus methods: original-center, re-center, and aiming-point; and two zoom scales: +100% and +400%) for two age groups (younger and older adults) on mouse-based information searching tasks in a map-type two-dimensional information space. Twenty four volunteers (twelve users per age group) participated in the experiments by answering a pair of questions about fifty movie information topics. Task completion time, number of operations, and number of errors were selected as performance measures, and a subjective assessment of satisfaction was collected. Older adults used the tested ZUIs less efficiently and precisely than younger adults. The effects of zoom focus methods vary with zoom scale levels regardless of the age groups. The participants also preferred using the aiming-point focus regardless of zoom scale and using the re-center focus with the +400% scale. We discuss potential implications of the age-related performance differences and the effects of ZUI functions, and suggest some ZUI design guidelines in conclusion. We expect that the findings can be used as basic resources in designing various web services and applications for older computer users.

Relevance to industry

Given that a zoomable user interface is widely used in basic geographic information systems, web services, and various applications, using a selective-focus method such as the aiming-point focus can improve computer users’ usability; in particular, the zooming functions will greatly help older people to explore large information spaces quickly and easily.     

From broadcast television to Internet audio/video: techniques and tools for VCR‐style interactivity

One of the new applications evolving in the Internet is streaming audio/video. A major reason for its growing popularity is interest in the compelling new services that become possible. Prototype services are being developed which are new to the Internet but offer the same look, feel, and functionality that have traditionally only been found in services delivered via other communication medium, e.g. broadcast television. In addition, the Internet is evolving to offer ‘value‐added’ services, like streaming audio/video with VCR‐style interactivity and embedded hyperlinks. We are poised both on seeing the development of new paradigms for interacting with audio/video, and on seeing the merging of broadcast television and Internet‐based broadcasts. Before this process can be considered successful, a number of technical challenges, derived from the various ways in which content is physically delivered, must be solved. In this paper, we focus on the value‐added service of VCR interactivity. VCR interactivity has long been a challenge for both broadcast television and streamed Internet audio/video. The challenge is how to provide individualized playout for content being streamed to a large group of users using one‐to‐many delivery. While some new companies are starting to offer devices which provide this kind of service for broadcast television, there are still numerous technical challenges for the Internet‐based version of a similar service. This paper has a three‐fold objective. First, we describe the types of services available in the traditional broadcast infrastructure and compare these to the types of services that are deployed or possible in Internet‐based services. Second, we describe our attempts to implement some of the more challenging and novel service types. In particular, we examine client‐based control of programs streamed over the Internet to tens, thousands, or even millions of users. Finally, we discuss the impact of these services on the protocols and applications used to support Internet‐based, multi‐party conferencing. Copyright © 2001 John Wiley & Sons, Ltd.     

Age differences in information finding tasks: Performance and visual exploration strategy with different web page layouts

Recent research suggests that older Internet users seem to find it more difficult to locate navigation links than to find information content in web pages. One possibility is that older Internet users’ visual exploration of web pages is more linear in nature, even when this type of processing is not appropriate for the task. In the current study, the eye movements of young and older Internet users were recorded using an ecological version of the web pages or a discursive version designed to induce a linear exploration. The older adults found more targets when performing content-oriented compared to navigation-oriented searches, thus replicating previous results. Moreover, they performed less well than young people only when required to locate navigation links and tended to outperform the younger participants in content-oriented searches. Although the type of search task and type of web page resulted in different visual strategies, little or no support was found for the hypothesis that older participants explore web pages in a more linear way in cases where this strategy was not appropriate. The main conclusion is that differences in visual exploration do not seem to mediate the specific difficulty older adults experience in navigation-oriented searches in web pages.
