User Studies Laboratory (USL): The Human Computer Interaction Institute (HCII) in the School of Computer Science (SCS) at Carnegie Mellon University currently has three User Studies labs totaling 1400 sq. ft. which can be used as part of this research for controlled experiments and formal usability analyses. The USLs have been used for dozens of investigations into the usability of new technology and interaction techniques, including speech-recognition, command languages, help systems, computer-aided instruction, and collaborative writing, and using new technologies such as personal digital assistants, video communications, and wearable computers. The USLs are also used in teaching students to perform "think-aloud' usability studies and to conduct experiments. The labs have equipment for single-user and multi-user within-laboratory as well as field recording of color video data.

Interactive Systems Laboratory (ISL): The development efforts will be located here. It is equipped with state-of -the-art systems for speech recognition, handwritten character recognition, gesture recognizing, face and eye tracking, and other systems relevant to the current project. Because many of these systems were developed and tested "in house" they can be modified to fit the needs of the proposed research.

Laboratory in S.U.N.Y. Stony Brook: Brennan's laboratory consists of approximately 1500 square feet and comprises a suite of four rooms organized around a hallway with observation windows, storage space, telephone, and a reception area for the instruction and debriefing of human participants. This lab currently contains three Pentium 400 PCs and eight Macintoshes (two of which are dedicated to signal processing and digital speech), as well as two printers and audio and video equipment. This lab is used to study psycholinguistics and human-computer interaction, and it is easily reconfigured to accommodate different experimental paradigms.
