内容简介：
　　Accessing the Web from mobile handheld devices has become increasingly popular in our daily life yet remains challenging due to the physical constraints of those devices. Adapting the presentation of Web pages is, therefore, critical to enabling effective Web browsing and information searching on such devices. Based on Cognitive Fit Theory and Information Foraging Theory, we propose a hybrid approach to adapting Web page presentation dynamically. The approach integrates three types of adaptation techniques, namely tree-view, hierarchical text summarization, and colored keyword highlighting. By following the design science research framework, we implemented the proposed approach on mobile handheld devices and empirically evaluated the effects of presentation adaptation on Mobile Web browsing. The results show that presentation adaptation significantly improves user performance and perception of Mobile Web browsing. We also discover that the positive impact of presentation adaptation is moderated by the complexity of an information searching task. The findings have significant theoretical and practical implications for the design and implementation of Mobile Web applications.
