Outline

• GUI Evaluation for Dundee
• Arrival Set-up of Nubira
• Control Location/Operation Study
• Summary
• Ongoing/Future Work

3
GUI Evaluation

• ACTIVE GUI Test Prog. Informal Feedback to Dundee
  
• General recommendations re. control
• Type
• Size
• Shape
• Menus
• Feedback

4
Nubira Arrival
5
Set-up
6
Conventional Control Activation
7
Conventional Controls

• Give instant tactile feedback
• Drivers know when control has been de/activated
• Drivers have an indication of the range at which
  the control is currently set at

Consultation of Relevant Research

• Phase I Physical Design of ACTIVE e.g. Location
  of control/display panel recommendations
• Phase II Design of Interface
• e.g. Control/button size

11
Example of Button Diameter Recommendations (mm)

• Min Max Source
• 9.5 50 MIL-STD-1472
• 6mm 13-25 Diffrient et al, 1981
• 10 (20 gloved) 25 DEF STAN 00-25

12
But.

• Pushbutton recommendations not directly
  appropriate as dont actually touch ACTIVE
  control
• Therefore need to take into account
• Other types of feedback
• Vibration

13
Control Panel Location Study Aim

• To investigate the effect(s) of different
  locations of control panel on driving

14
Objectives

• Stages of control activation
• Number of glances taken to activate control
• Duration of glance(s) whilst activating control

15
Objectives (Contin.)

• Time taken to activate control successfully
• Any errors made their type
• Drivers different methods of ACTIVE control
  activation

Stages of Control Activation
20
Stages of Control Activation
21
1. Normal driving
22
2. Start to move hand
23
3. Hand nears control activation zone
24
4. Control activated
25
No. Duration of Glances Taken to Activate
Control (Secs)

• Location Min Max Mean
• 1 0.55 0.86 0.76
• 2 0.69 1.50 0.99

26
Time taken to Activate Control (Secs)

• Location Min Max Mean
• 1 1.29 2.23 1.76
• 2 1.21 1.8 1.48

27
Example of Error Types

• Didnt attempt to activate the control
• Hit incorrect control
• Missed hitting the control

28
Consequences of Errors

• What will the system do?
• What feedback does the driver get when there has
  been an error?

29
Drivers Methods of Control Activation
30
Drivers Method Affected By

• Anthropometry
• Static e.g. Hand size arm length
• Dynamic e.g. Reach
• Age
• Previous experience
• Driving situation e.g. straight/curved road
• Etc!

Summary

• Evaluating GUI/providing support/advice for
  ACTIVE system development
• Arrival of Nubira/Set-up
• Investigating control location/operation

34
Ongoing/Future Work

• Extend this study
• Other locations
• Increase complexity of road scene
• No. of tasks to be performed
• Increase complexity of display
• Phase II Interface Design e.g. control
• Dimensions
• Feedback
