Overview
Activity Tracing and Task Context
My research interests include user interfaces and information retrieval; namely identifying what users' interaction with interfaces can tell us about the relationship between those users and the information those interfaces expose. One of the specific objectives has been identifying relationships between the users' information (e.g., files) by inferring common task context through observed patterns within their interaction with that information through the user interface. For example, the
SeeTrieve
system associates the text which is made visible in UI application windows with the files with which the user interacts at proximal points in time. This enables users to recall misplaced documents by using textual information which surrounded those documents' use in time.
FaceTop
My previous project was
FaceTop
, a remote collaboration tool which combined a shared screen with a semi-transparent, video teleconferencing overlay to facilitate fine-grained, gestural interactions between users. More information can be found
