Title: Solving the correspondence problem for image sequences.

Abstract: One of the key problems in vision is the correspondence problem. Given two overlapping images, the goal is to find the matching 2D projections of the same 3D image features. In this talk we will describe a system which uses robust statistics and projective vision to solve the correspondence problem. What is new is the fact that the resulting correspondences are automatically computed in unstructured natural scenes, and are very reliable. It is also true that this can be accomplished for images for which nothing is known about the camera, what are called un-calibrated image sequences.

The goal is to use this ability in a number of tasks, one of which is to perform augmented reality in real-time. The talk will be illustrated by a number of results which show our ability to solve the correspondence problem for difficult sequences, and in doing so reliably compute the camera positions.

Title:

Symmetric Bimanual Interaction.
 
Abstract:

I'm going to talk about this CHI 2000 paper by Ravin Balakrishnan and Ken Kinckley. It looks at factors that influence performance on bimanual tasks for which each hand is assigned an identical symmetric role. It shows that when given these symmetric tasks, subjects don't always perform the task in a parallel and symmetric way.
