Adult age differences in information foraging in interactive reading environments
… multiple resources varying in type and amount of information. In this situation, readers are free to select the resources and allocate time for study, but there may be costs in exploring and switching between resources. Thus, two experiments were conducted to investigate age differences in the …

Investigating the Applicability of Information Foraging Theory to Mobile Web Browsing
Major research studies have provided support for information scent based usability evaluation and have increased its parent theory's (Information Foraging theory) credibility in the HCI community. These studies have, directly and indirectly, found significant correlations between good information …

Exploring Usage of Web Resources Through a Model of API Learning
… an acronym for “Collection and Organization of Information for Learning,” was recently developed to model the entire API learning process, drawing from information foraging theory, cognitive load theory, and external memory research. We ran an exploratory empirical user study in which …

ClickTrails: Enhancing Web Navigation with Usage-Based Stylization of Clicked Web Page Elements
… web pages. Drawing inspiration from concepts in information foraging theory, this thesis investigates methods to capture and visualize the typically unseen traversals made by users in the online domain as a method of improving the information scent of web pages. We introduce ClickTrails, a …

Footprints : interaction history for digital objects
Digital information has no history. When we interact with physical objects, we are able to read the traces left by past interactions with the object. These traces, sometimes called "wear," form a basis for the interaction history of the object. In the physical world, we make use of interaction …

Crowdsourcing decision support: frugal human computation for efficient decision input acquisition
… process. The unprecedented availability of information online has created opportunities to make well-informed, near-optimal decisions more efficiently. A key challenge that remains is the difficulty of efficiently gathering the requisite details in a form suitable for making the decision. …

Consumption of Content on the Web: An Ecologically Inspired Perspective
How do people search for and organize informational resources on the web? This dissertation explores this question in the context of music tagging and listening, incorporating web data mining and machine learning methods with theory from cognitive science. In particular, I draw inspiration from …

A framework for understanding user interaction with content-based image retrieval: model, interface and users
… on different user types. Accordingly, based on Information Foraging Theory, we further propose a user classification model along three user interaction dimensions: information goals (I), search strategies (S) and evaluation thresholds (E) of users. To our best knowledge, this is the first …

The Impact of Information Presentation Format on User Purchase Decision-Making
… years, from scholars in various domains (such as information systems and marketing) seeking to understand their role in purchase decision-making. With the growing popularity of online review videos, however, understanding the role of information presentation format in online decision-making …

Heavy Tails and Anomalous Diffusion in Human Online Dynamics
… My work starts with a discussion of the human information foraging process based on three large collections of empirical search click-through logs collected in different time periods. With the analogy of viewing the click-through on search engine result pages as a random walk, a variety of …

Application of Human-computer Interaction Theories to Information Design on Internet Portals
… are increasingly becoming a primary source of information. A portal is a gateway to information on the Internet or a hub from which users may locate relevant information (Strauss, 2000). Because university Web sites have various user classes, universities are beginning to adopt the portal …

Age differences in search during self-regulated learning
… that domain. By manipulating the amount of new information and conceptual overlap across texts within a topic, we created three types of text environments to generate different trajectories of two cues to perceived learning, new information (measured by rating of perceived new information) and …
