                 "EMPOWERING PEOPLE"

             The 7th Annual Conference on
          Human Factors in Computing Systems

                   1990 April 1-5

 CHI'90 will provide an environment where Computer-Human Interaction
 comes alive, where understanding and ideas are developed, where new
 styles, techniques and applications are explored. CHI'90 will be more
 than a conference, it will be an event.

 In addition to an excellent and international tutorial and technical
 program, we will be presenting "EMPOWERED", a set of live interactive
 performances, and making the latest in interaction available for hands-
 on exploration in "THE INTERACTIVE EXPERIENCE".  CHI '90 will not only
 be a technically excellent event, it will be FUN and an experience to
 remember.

 The CHI '90 Conference will be held at the Washington State Convention
 and Trade Center in Seattle, Washington with additional events being
 held next door in the Seattle Sheraton.


 TUTORIALS:  Sunday & Monday, April 1-2

 CHI'90 begins with two full days of tutorials by leading CHI
 researchers and practitioners on user interface design and principle,
 innovative user interfaces and techniques, user interface programming
 environments and toolkits, and special topics.  For an email
 description of the workshops, write MEADS.CHI@XEROX.COM.

 Closing Address:  Dr. Terry Winograd, Stanford University



 CONFERENCE RECEPTION:   The CHI '90 Conference Reception will be on
 Wednesday evening, April 4, 1990 at the Museum of Flight.

 LABORATORY REVIEWS
 The function of these reviews is to draw attention to significant
 concentrations of CHI research. A senior member of the laboratory will
 present the review, which will include a sketch of the full range of
 projects and activities. Special opportunities for collaborative
 projects and for visiting appointments for students and scientists will
 be described.

 FORMAL VIDEO REVIEW
 Technical videotape presentations will be shown continuously at CHI '90
 in a designated Video Theater area and on special TV channels in the
 hotel rooms of participating CHI '90 conference hotels. The videos will
 present important innovations in computer-human interface from
 academic, industrial, and governmental groups.

 INFORMAL VIDEO PRESENTATIONS
 You are invited to bring videotapes to the conference to be shown to
 other attendees. An "Informal Video Room" will be available where you
 can either leave your tapes for others to see at their leisure, or
 where you can schedule a showing during the conference. Tapes must be
 in VHS, NTSC format, and clearly marked on the spine with your name and
 the tape title. Please drop off and pick up your tape in the Informal
 Video Room. There will be some security, but we cannot be responsible
 for lost or stolen tapes.

 EXHIBITS
 The latest products and services from commercial firms and publishers
 will be displayed and demonstrated in the Exhibits area which is
 adjacent to the technical sessions.

 LOCAL SHOWCASE TOUR
 On Friday, April 6, attendees are offered a tour of local labs and
 companies with significant activities in CHI. The tour buses will leave
 the Sheraton at 9:00 a.m. to visit Seattle area labs, stop for lunch,
 and return by 5:00 p.m. Hosts include:

        Boeing Advanced Technology
        Bolt, Beranek & Newman Graphics
        Human Interface Technology Lab, University of Washington

 Each site visit will include an overview of the charter and history of
 the lab, its staff and their computing environment, and an overview of
 the site tour. The cost of the tour is $75, and includes lunch and all
 transportation. Attendance is very limited. If you wish to take the
 tour, send in your registration form early.

 DEMONSTRATIONS
 Live demonstrations of experimental user interfaces will be presented.
 These will expose CHI '90 attendees to the latest developments in
 experimental user interface research. An informal demonstration area
 will also be available for one-to-one and small group demonstrations of
 systems that developers personally bring to the conference.

 FUN RUN
 For those who want to join a select band of colleagues for a brisk wake
 up, we will hold the CHI '90 Fun Run at 7:15 Wednesday morning.
