easily accessible by anyone, with or without a disabilitysupportive of a wide variety of teaching stylesdesigned through a user-driven design lifecycleProject Definition5Eric Neisenconceptuser testingrefineSource: youtube.com\education

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

An estimated 54 million individuals within the US alone have some type of limitation.-Source: Survey of Income and Program Participation (SIPP)7Robin SchwartzSpecifications2010 ADA StandardsMet?Toe Clearance Depth - 17- 25YKnee and Toe Clearance Minimum Width - 30YKnee Clearance Minimum Height - 27YWork Surface Maximum Depth 25YWork Surface Height - 28- 34YBIFMA Product StandardsWork Surface Static Load Requirement - 300 lb.Y/NRacking TestYSteelcase Requirements Meets Budget - $1,000NPromotes Sustainability??Aesthetics Similar to Steelcase Products??Allows for sitting and standing workYAppropriate wire and utility managementYAccommodates technology now, and in near futureY8

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

A fewSit frequently during lecture10Kevin Clark

Design Selection

11Kevin ClarkConcept 2: Modular Lectern

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
