Title: Usability Evaluation of 4D Tool on Smart Board


1
Usability Evaluation of 4D Tool on Smart Board
  • ??? (Han-Shuo Nick Chang)
  • ??? (Chung-Han Hank Yu)
  • ??? (Albert Hsu)

2
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

8
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.

10
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
