6Robin SchwartzWhat is a lectern??
A structure or device which
(1) provides access to current teaching technologies (2) allows control of classroom media
Project MotivationTypical lecterns and podiums are not accessible by users with disabilities
SOLUTION Universal DesignUniversal design is an approach to design that incorporates products as well as building features which, to the greatest extent feasible, can be used by everyone.-Ron Mace, founder of universal design

A substantial amountWant all room controls integratedWant less complexityUse doc cams, when availableComplained of having to click slides

Concept 1: Rotary Lectern
Concept 3: Two-Part LecternTwo-part concept selected by Steelcase. IncSpring User-Testing12
Reached 53 instructors from various specialties at Northern Arizona University
Suggestions for improvementBase cabinet and lectern surface were too largeSurface must be tilt adjustable
Positive FeedbackEase of wheelchair accessHeight adjustment mechanismWireless freedom
Conflicting FeedbackNecessity of sidewallMonitor placementPower source
Kevin ClarkApplication of User-Test ResultsInterview OutcomeDesign Addition1234513Wanted more freedom to move around the roomAttach casters, and reduce overall weightsurface of the foam prototype was excessively largeUse an open textbook and piece of 8.5 x 11 paper to size final surfacevertical computer monitors are a barrier between teacher and studentsInlay a monitor into the surface, which can be written upon, or tilted upwardsangled surfaces are more comfortable to useDesign a mechanism that allows entire surface to tiltconflicting preferences on type of power source for the lecternSpecify an uninterrupted power supply, which can run on battery power, or be bypassed with outlet powerKevin Clark
