Abstract. We present Supple, a novel toolkit which automatically generates interfaces for ubiquitous applications. Designers need only specify declarative models of the interface and desired hardware device and Supple uses decision-theoretic optimization to automatically generate a concrete

of inaccurate segmentation, 2) helps to clarify the semantics of a particular region, and 3) enables a simple querying interface for region-based image retrieval systems. The application of SIMPLIcity to several databases, including a database of about 200,000 general-purpose images, has demonstrated that our

-area telecommunications network that is operating in close quarters. The technical steps toward making Myrinet a reality included the development of (1) robust, 25m communication channels with flow control, packet framing, and error control; (2) self-initializing, low-latency, cut-through switches; (3) host interfaces

The field of Human Computer Interaction (HCI) proposes several kinds of models for predicting aspects of user's behavior. Although these models deal with user's behavior with interactive computer systems, they do so rather poorly. HCI should be designed to be versatile enough to handle a broad range of interactions between a man and a machine, rather than depending on a pre-defined user model. A goal in HCI is to develop cooperative systems: for a system to cooperate with a user, it must be able to determine what the user is trying to accomplish, that is, it must recognize user plans. For a system to exhibit the intelligence required in a dialogue with a user it needs the ability to understand and reply properly to a wide range of responses. Additionally, if a system fully participates in a dialogue, it can support ad hoc requests from a user, maintain the topic of discourse, and keep a user from digressing out of the subject. Toward this goal of participation, we focus on handling a u...

;latency-insensitive" protocols) to mixedtiming domains. The new designs can be made arbitrarily robust with regard to metastability and interface operating speeds. Initial simulations for both latency and throughput are promising.

The new algorithm developed here is based on a robust nonparametric technique for climbing density gradients to find the mode (peak) of probability distributions

Over the last decade, automatic facial expression analysis has become an active research area that finds potential applications in areas such as more engaging human-computer interfaces, talking heads, image retrieval and human emotion analysis. Facial expressions reflect not only emotions

Market mechanisms, such as auctions, will likely represent a common interaction medium for agents on the Internet. The Michigan Internet AuctionBot is a flexible, scalable, and robust auction server that supports both software and human agents. The server manages many simultaneous auctions
