I am currently building an active visual tracking system for a real world robot. The hardware is being built at MIT under the supervision of Professors Rod Brooks and Lynn Andrea Stein, and is humanoid in form. The software is also humanoid: I am basing its organization on models of early vision in the human brain. Most of the software is still in the design phase; what I describe here is the p...

We investigate secondary view techniques in a multimodal VR environment for dataset exploration and interpretation. Secondary views, such as 3D lenses or mirrors, can present alternative viewpoints, different filtering options, or different data sets. We focus on 3D views showing surface features that are hidden in a main view. We present different view techniques, including new variations, and...

As co-operative work environments are becoming more popular, new tools and techniques have been emerging that allow users to perform collaborative tasks more efficiently. We have been exploring new interaction techniques made possible by using a multi-view display as a tabletop surface. This paper presents the concept of public and private working areas for multi-view display environments, and ...

Based on a confocal microscopy platform, we extended the FCS time window by three orders of magnitude to the s timescale by attaching a polystyrene microsphere. We simultaneously monitored the relaxations of multiple intermediates involved in DNA hairpin folding, thus offering a much more detailed view of the kinetics of hairpin folding experimentally.

We demonstrate a 16-channel, independently tuned waveguide surface grating optical phased array in silicon for two dimensional beam steering with a total field of view of 20° x 14°, beam width of 0.6° x 1.6°, and full-window background peak suppression of 10 dB.

An algorithm is presented to answer window queries in a quadtree-based spatial database environment by retrieving the covering blocks in the underlying spatial database. It works by decomposing the window operation into sub-operations over smaller window partitions. These partitions are the quadtree blocks corresponding to the window. Although a block b in the underlying spatial database may co...

Functional brain networks reconfigure spontaneously during rest. Such network dynamics can be studied by dynamic functional connectivity (dynFC); i.e., sliding-window correlations between regional brain activity. Key parameters-such as window length and cut-off frequencies for filtering-are not yet systematically studied. In this letter we provide the fundamental theory from signal processing t...

When designing executable user interfaces, it is often advantageous to use declarative and procedural approaches together, each when most appropriate: − A declarative approach can be used to define widget types, their initial states, their resize behavior, and how they are nested to form each window. All this information can be represented as a data structure. For example, widgets can be record...
