Research in the DIEM project is focused on understanding human vision during complex real-world scene perception. Because human visual perception involves active information seeking via eye movements, much of the work in the lab focuses on eye movements and human gaze control.
Topics of interest in the lab include fast scene recognition, visual search in natural scenes, visual memory and scene representation, eye movement control during static and dynamic scene viewing, and the integration of visual and linguistic information in natural contexts.
We are also interested in computational approaches to these questions and implementation of underlying processes in the human brain as revealed by neuroimaging techniques such as pupillary response, fMRI and ERP.
We have built an imaging solution that allows us to visualize propagation of light at an effective rate of one trillion frames per second. Direct recording of light at such a frame rate with sufficient brightness is nearly impossible. We use an indirect 'stroboscopic' method that combines millions of repeated measurements by careful scanning in time and viewpoints.
The device has been developed by the MIT Media Lab's Camera Culture group in collaboration with Bawendi Lab in the Department of Chemistry at MIT. A laser pulse that lasts less than one trillionth of a second is used as a flash and the light returning from the scene is collected by a camera at a rate equivalent to roughly 1 trillion frames per second. However, due to very short exposure times (roughly one trillionth of a second) and a narrow field of view of the camera, the video is captured over several minutes by repeated and periodic sampling.
