We introduce Olympus, a freely available framework for research in conversational interfaces. Olympus' open, transparent, flexible, modular and scalable nature facilitates the development of large-scale, real-world systems, and enables research leading to technological and scientific advances in conversational spoken language interfaces. In this paper, we(More)
The <i>personal universal controller</i> (PUC) is an approach for improving the interfaces to complex appliances by introducing an intermediary graphical or speech interface. A PUC engages in two-way communication with everyday appliances, first downloading a specification of the appliance's functions, and then automatically creating an interface for(More)
In Cognitive Tutors, student skill is represented by estimates of student knowledge on various knowledge components. The estimate for each knowledge component is based on a four-parameter model developed by Corbett and Anderson [Nb]. In this paper, we investigate the nature of the parameter space defined by these four parameters by modeling data from over(More)
A novel thermodynamically-balanced inside-out (TBIO) method of primer design was developed and compared with a thermodynamically-balanced conventional (TBC) method of primer design for PCR-based gene synthesis of codon-optimized gene sequences for the human protein kinase B-2 (PKB2; 1494 bp), p70 ribosomal S6 subunit protein kinase-1 (S6K1; 1622 bp) and(More)

Several industrial and academic research groups are working to simplify the control of appliances and services by creating a truly universal remote control. Unlike the preprogrammed remote controls available today, these new controllers download a specification from the appliance or service and use it to automatically generate a remote control interface.(More)
This research investigates the design and performance of the Speech Graffiti interface for spoken interaction with simple machines. Speech Graffiti is a standardized interface designed to address issues inherent in the current state-of-the-art in spoken dialog systems such as high word-error rates and the difficulty of developing natural language systems.(More)
We envision a future where each person will carry with them a personal universal controller (PUC), a portable computerized device that allows the user to control any ap-pliance within their environment. The PUC has a two-way communication channel with each appliance. It downloads a specification of the appliance's features and then automati-cally generates(More)
In this new era of space exploration where human-robot teams are envisioned maintaining a long-term presence on other planets, effective coordination of these teams is paramount. Three critical research challenges that must be solved to realize this vision are the human-robot team challenge , the pickup-team challenge, and the effective human-robot(More)
One of the acknowledged impediments to the widespread use of speech interfaces is the portability problem, namely the considerable amount of labor, data and expertise needed to develop such interfaces in new domains. Under the Universal Speech Interface (USI) project, we have designed unified look-and-feel speech interfaces that employ semi-structured(More)
