1. Looking At You: Fused Gyro and Face Tracking for Viewing Large Imagery on Mobile Devices.

We are all familiar with finger swipes and pinching motions to interact with images on a mobile device. In the first of the two short talks I will outline a method for leveraging the fact that a device with a front facing camera can see the viewer. This sense in addition to other sensors (e.g., gyros) provide the means to interact with a variety of imagery types without touching the device directly. In particular, I will focus on viewing paradigms for 360 degree panoramas, parallax image sequences, and long multi-perspective panoramas. A sensor fusion methodology combines face tracking using the front facing camera with gyroscope data to produce a robust signal that defines the viewer’s 3D position relative to the display. This work will be presented at CHI 2012, and is a collaboration with Neel Joshi, Steven Drucker, and Abhishek Kar.


2. DrawAFriend: A Drawing Application Embedded in Facebook for Creating and Sharing Drawings of your Friends.

People love drawings but are often afraid to create them. In this talk I will show a Facebook embedded “game” we are developing that will help people easily create drawings of their friends on Facebook, and them, and curate a Gallery of their own and others’ artwork. This work is in collaboration with Alex Limpaecher, Larry Zitnick, and Adrien Treuille.

Michael F. Cohen is a Principal Researcher at Microsoft Research, and an Affilate Professor of Computer Science and Engineering at the University of Washington. He arrived in Seattle in 1994 from Princeton University where he served on the faculty of Computer Science. Michael received The 1998 SIGGRAPH Computer Graphics Achievement Award for his contributions to the Radiosity method for image synthesis. Dr. Cohen also served as paper's chair for SIGGRAPH '98.

Michael received his Ph.D. in 1992 from the University of Utah. He also holds undergraduate degrees in Art and Civil Engineering from Beloit College and Rutgers University respectively, and an M.S. in Computer Graphics from Cornell. Dr. Cohen also served on the Architecture faculty at Cornell University and was an adjunct faculty member at the University of Utah.

His early work at Cornell and Princeton on the radiosity method for realistic image synthesis is discussed in his book "Radiosity and Image Synthesis" (co-authored by John R. Wallace). His work at the University of Utah focused on spacetime control for linked figure animation

At Microsoft, Dr. Cohen has worked on a number of projects ranging from image based rendering, to animation, to camera control, to more artistic non-photorealistic rendering. One project focuses on the problem of image based rendering; capturing the complete flow of light from an object for later rendering from arbitrary vantage points. This work, dubbed The Lumigraph is analogous to creating a digital hologram. Michael also has continued his work on linked figure animation, focusing on means to allow simulated creatures to portray their emotional state. Recent work has focused on computational photography applications. These ranged from creating new methods for low bandwidth teleconferencing, segmentation and matting of images and video, technologies for combining a set of "image stacks" as a Photomontage , to the creation of very high resolution panoramas.
