What is Smart Board?

• Interactive Whiteboard

What is 4D?

• 3D Models Construction Schedule
• For Construction Planning

3
Outline

• User and User Need
• Existing Approaches
• Low Fidelity Prototyping
• High Fidelity Prototyping Evaluation
• Summary

4
User and User Need

• Interview
• 1 Worker
• 1 Designer
• 3 Engineers

5
User and User Need

• Domain Knowledge

Engineering
Presentation Skill
Discipline Knowledge
Computer Science
6
User and User Need

• Goal
• Make decisions
• Discuss methods
• Review processes
• Problem
• Reschedule
• Record the process of consulting
• Navigate in the 4D models

7
Existing Approaches

• Panasonic Panaboard
• 4D Tool (Under Development)
• Rescheduling Component
• Navigation Controller of 3D World

Low Fidelity prototype --
How we create our prototype?

• Paper Smart Board based on the real size.
• Using Post It instead of saving icon and
  schedule changes.
• Transparent plastic hand- drawing panel
  controller.
• boxes as our object model.

9
2 tasks were designed for User testing
Low Fidelity prototype --

• Using paper smart board to achieve scheduling and
  making consensus and saving function based on our
  script.
• Using panel controller to review the model.

EngineerWow!! Its sooooo interesting!
Low Fidelity prototype --
User Testing
Model Manipulator
Story teller In this part, an engineer will
confront these problems blahblahblah
11
Findings
Low Fidelity prototype --

• Easier accessible objects to get the users
  reaction toward our design
• The size of current icons are not appropriate.
• Highly satisfaction of the functions of saving
  and 3D controller.

12
Why we choose Flash?
High Fidelity Prototyping Evaluation --

• Image-based
• Interact with touch screen
• Simulate 4D User Interface

13
Prototyping
High Fidelity Prototyping Evaluation --

• Selecting Object
• Constructing Schedule
• 4D Simulation
• Progress Player

14
Evaluation
High Fidelity Prototyping Evaluation --

• We asked two engineers to do evaluations with
  test driving our prototype!

15
Finding
High Fidelity Prototyping Evaluation --

• Icon is still too small
• New generation of Time Selector!!

16
Summary

• Usability Requirements

17
Summary

• Constraint 1
• Only Supports Single-Touch
• New Approaches Multi-Touch Sensing at NYU Media
  Lab
• Constraint 2
• Bad Sensibility
• UI, More Important

18
Summary

• Interesting Issues
• Remote Controller
• UI Layout at Multiple Display Screens
