Information Scents and Sensibility

by davidcrow

This is a very interesting article about information scent and predictive software. The concept of information scent is an interesting one, it has been proposed . The article describes the “Bloodhound”; program developed by Ed Chi and Stu Card at Xerox PARC. The program has a predictive model of human behaviour that allows it to predict the path a user would take in traversing a web site for a given target. First Bloodhound takes a snapshot of a web space and then assigns a vector to each page. The software then compares the vectors mathematically and follows the “scent” until it reaches the goal. This is a great example of how HCI research into cognitive models and information process in starting to be applied to design tools.
