1 1 The Enhanced Classroom Development Process: Standards and Practices Andrew Faunce, Dartmouth College Michael Ney, Gettysburg College

2 2 The Enhanced Classroom Development Process: Standards and Practices Part I Design Theory Andrew Faunce

3 3 Large Screen Presentation Human Factors Design Principles Design Deliverables

4 4 Human Factors Visual Perception Aural Perception Body Size and Movement

5 5 Visual Perception a (N.T.S.) a 10 Mins. of Arc (V) ¼ Height for Every 7 Distance Based on IDEAL Conditions Unreliable Beyond 90 Degree (H) Viewing Cone Central Vision – Detail Peripheral Vision – Motion

6 6 Aural Perception Directional Cues ? Level Differences Perceived at 2dB

7 7 Body Size Head Height – 40 Eye Height – 36 Ear Height – 36

8 8 Body Movement EASY/MAX Head/Eye Movement HORIZONTAL VERTICAL (N.T.S.)

9 9 Design Principles Viewing Distances Image Size Angles of View Line of Sight Sound System Requirements Speaker Performance and Placement

10 10 Most Distant Viewer General Viewing Reading/Detail Inspection a X 8X 6X 4 = 8 x Screen Height = 6 x Screen Height = 4 x Screen Height

11 11 Screen Height Calculation General Viewing= MDV / 8 Reading/Detail= MDV / 6 Inspection= MDV / 4 /4 /6 /8

12 12 Closest Viewer Calculation Closest Viewer = 1 x Screen Width Screen (top view) Ergonomic Easy to Remember All Viewers in 90 degree (H) Viewing Cone

13 13 Angle of View - Horizontal Solving for ALL Possible 90 Degree Viewing Cones Most Reliable Best for Inspection Most Costly

14 14 Angle of View - Horizontal Solving for 90 degree Viewing Cone Reliable for Reading and Moderate Detail Viewing Used Most Often (1)

15 15 Angle of View - Horizontal Solving for the UNION of all 90 degree Viewing Cones Acceptable for General Viewing (VIDEO) Less Costly

16 16 Angle of View – Vertical 30

17 17 Sight Lines

18 18 Sound System System Requirements Speaker Performance Speaker Location

19 19 System Requirements Directional Sound Location Cues Important (Videos) Speakers Mounted Near Screen High Ceilings w/ Line of Sight to Viewers Distributed Sound Location Cues Not Important Ceiling Speakers (typical) Low Ceilings or Interrupted Line of Sight

20 20 Directional Sound

21 21 Distributed Sound 90 -3dB S = 1.4 x R S R = ceiling ht – 36 R

22 22 Distributed Sound More Ceiling Height = Wider Coverage Zone Speakers Front to Back to Compensate Zone 1 Zone 3 Zone 2

23 23 Design Deliverables Programming: Program Statement Design: Design Package Not for Construction Docs Construction: Build Package Construction Docs

24 24 Program Statement Text Description of Requirements Room Functions Seat Count/Arrangement Logistics of Use System Performance Provide Examples and as Much Detail as Possible
