Systems such as the HP-100 palmtop and the Apple Newtonrepresent the state-of-the art in autonomous mobile devices. Thesemachines, while offering substantial storage capacity and computingpower, have only limited communication capabilities. As a result, theydo not enable users to access the powerful computing infrastructurethat has been developed over the last 20 years. <p>In this project, we are exploring the design of system and applicationsoftware for high-powered, highly-connected mobile devices. Our modelis that mobile networks based on radio and infrared (IR) will soonoffer bandwidth comparable to today's Ethernet. With this, will comethe challenge of writing and using applications that are capable ofadapting to rapid changes in location, and working with a broad rangeof computing devices having small screens and novel input devices. <p>Our goal is to provide an application programming environment thatfrees the programmer from concerns about location, connectivity,bandwidth, screen size, and style of input device. We envision thatpeople will operate in our building-wide mobile network by running acombination of high-powered complex applications written by experts,and simple custom tools built by themselves. By analogy, people todayuse a small set of core programs, such as emacs, latex, and mosaic, incombination with personal programs based on custom shell scripts andlittle languages such as awk. We are exploiting several technologiesto achieve this goal: <p><ul><li> We are using an initial hardware and software infrastructurebuilt around the Xerox Palo Alto Research Center's (PARC) ``UbiquitousComputing Project.'' The hardware includes low-power, infraredtransceivers and handheld pen-based tablets. The software includes anapplication suite and service infrastructure that allows the handhelddevices to operate with stationary applications written in Modula-3.<li> In conjunction with Xerox PARC, we are writing software thatallows us to use standard, off-the-shelf computing devices such asHP-100s and Apple Newtons in conjunction with our IR network. <li> We are building a set of application ``widgets'' based on asimple user-interface command language that relieves programmers fromworrying about the display characteristics of various handhelddevices.<li> We are writing a programming environment built around C, ratherthan Modula-3, both to broaden the set of users who will be attractedto write applications, and to enable applications to run efficientlyon a wide-range of system configurations.</ul><p><h3>Contacts:</h3><ul><li><!WA0><!WA0><!WA0><!WA0><a href="http://www.cs.washington.edu/homes/bershad">Prof. Brian Bershad</a><li><!WA1><!WA1><!WA1><!WA1><a href="http://www.cs.washington.edu/people/faculty/zahorjan.html">Prof. John Zahorjan</a><li><!WA2><!WA2><!WA2><!WA2><a href="http://www.cs.washington.edu/people/faculty/borriello.html">Prof. Gaetano Borriello</a><li><!WA3><!WA3><!WA3><!WA3><a href="http://www.cs.washington.edu/homes/mef">Marc E.
