Modeling Information Navigation: Implications for Information Architecture
Previous studies for menu and Web search tasks have suggested differing advice on the optimal number of selections per page. In this paper, we examine this discrepancy through the use of a computational model of information navigation that simulates users navigating through a Web site. By varying the quality of the link labels in our simulations, we find that the optimal structure depends on th...
متن کاملHealthcare Choices, Information and Health Outcomes Healthcare Choices, Information and Health Outcomes
Self-selection into healthcare options biases estimates of the effects of healthcare on health outcomes. We exploit exogenous variation in the cost of formal-sector care to show that the use of such care improves short-term health outcomes for acutely ill children in Tanzania. Better treatment-specific information, rather than greater access to medicines, appears to be the primary mechanism for...
متن کاملMobile Reacher Interface for Intuitive Information Navigation
We propose Mobile Reacher Interface (MoRIn) that is a new interface with a visual tag for a mobile device. MoRIn allows users to navigate sophisticated information structures by making natural hand gestures while holding a camera-equipped mobile terminal. The structure of an item of interest is acquired via a visual tag. The user can then navigate the structure as if he/she is handling physical...
متن کاملModeling an Opportunistic Strategy for Information Navigation
A computational model of a user navigating Web pages was used to identify factors that affect Web site usability. The model approximates a typical user searching for specified target information in architectures of varying menu depth. Search strategies, link ambiguity, and memory capacity were varied and model predictions compared to human user data. A good fit to observed data was obtained for...
متن کاملInformation Sampling for vision-based robot navigation
This paper proposes a statistical, non-feature based, attention mechanism for a mobile robot, termed Information Sampling. The selected data may be a single pixel or a number scattered throughout an image. After ranking this data, we choose only the most discriminating to build a topological representation of the environment, obtained via Principal Component Analysis (PCA). Advantageously, usin...
