Compound Marking Menus
  • Advantages
  • Circular design
  • Fluid transition
  • Scale independance
  • Limitations
  • Screen space requirement
  • Number of commands
  • Error rate in expert mode
  • Ambiguous marks in expert mode

5
Multi-Stroke Marking Menus (Simple Hierarchical
Marking Menus)
Zhao 04
  • Solution

Instead of considering a spatial compound
stroke, Multi-Stroke menus introduce a serie of
simple strokes.

Multi-Stroke Marking Menus
Zhao 04
  • Require less physical input space in novice
    expert modes
  • Overlapped marks
  • Increase accuracy in expert mode
  • Increase the number of items
  • No ambiguous gestures in expert mode

7
Multi-Stroke Marking Menus
To sum up, Multi-Stroke marking menus have
several advantages that outperform Compound
Marking Menus in expert mode.
However
Interaction is degraded in novice mode
8
Multi-Stroke Marking Menus and Novice Mode
  • Menu parents are not visible
  • Submenus cannot be previewed

  • Introduction
  • NOVICE MODE

10
Why is the novice mode so important ?
  • It is the first interaction mode
  • necessary step before the expert mode
  • By exploring the menu, users learn where the
    commands are
  • It never disappears
  • Most commands are not often used
  • People with limited physical skills
  • It co-exists with the expert mode
  • Reuse after a long lay-off period

  • Introduction
  • Novice mode
  • OBJECTIVES

12
Objectives
  • A menu
  • As efficient as Multi-Stroke Marking Menus in
    expert mode
  • Efficient in novice mode
  • Usable with small screens

A new technique Wave Menus

  • Introduction
  • Novice mode
  • Objectives
  • WAVE MENUS

14
Wave Menus (1/4)
The main feature Parent menus surround submenus
  1. Menu appears
  2. Menu is enlarged
  3. Submenu appears
  4. Final item is selected

15
Wave Menus (2/4)
  • User looks for Paris
  • Scan Cities 1
  • Scan Cities 2
  • Scan Cities 3
  • Select Paris

Exploration of the menu hierarchy rapid scan of
different submenus
16
Wave Menus (3/4)
Scale independance
Fast animation to enlarge the root menu
17
Wave Menus (4/4)
  • Submenus Previsualization
  • Rapid scan of possibilities
  • Parent menus
  • Always visible
  • Can be directly selected
  • Visual stability of the focus of attention

18
Wave Menus (4/4)
  • Few physical input space
  • In expert mode, Wave Menus work exactly the same
    way as Multi-Stroke Menus

  • Experiment

20
Experiment
  • Comparison of novice mode efficiency
  • Compound Marking Menus
  • Multi-Stroke Marking Menus
  • Wave Menus
  • Inverted Wave Menus

21
Inverted Wave Menus
  • Wave Menus
  • Children of the menu tree in the center
  • Parents on the outmost rings
  • Inverted Wave Menus
  • Tree nodes are displayedin the opposite order

Inverted Wave Menus
22
Task and Stimuli
  • Exploration of a 2-level menu
  • Search cities
  • Stimulus
  • A city name with his corresponding continent
  • The city appears several times

One target
Ex, to find Paris in Europe, users must navigate
in the three Europe submenus
Menus to visit
23
Participants Apparatus
  • 12 volunteers
  • Mouse rather than Stylus
  • Most of our users had no experience in using pen
    tablets
  • Mouse is much more commonly used

24
Experimental design
  • 12 participants
  • X 4 menu techniques
  • X 3 submenu breadths (4,6 or 8 items)
  • X 6 times
  • 864 menu selections

25
Results Speed
  • No effect on Reaction Time.
  • Significant effect on Execution Time for menu
    techniques

26
Results Speed
  • No effect on Reaction Time
  • Significant effect on Execution Time for menu
    techniques
  • Wave Menus are 18 faster than Multi-Stroke
    Marking Menus
  • Previsualization has a major effect in improving
    navigation.
  • 11/12 subjects said that they could easily get
    lost in Multi-Stroke Marking menus.

27
Results Speed
  • No effect on Reaction Time
  • Significant effect on Execution Time for menu
    techniques
  • With Inverted Wave Menus, Users complainted about
    the excessive distance between the items they had
    to read.
  • With Wave Menus, most users (10/12) said they
    were not bothered by the reversed hierarchy after
    sufficient learning time.

Conclusion
  • Importance of novice mode.
  • Wave menus
  • As Efficient as Multi-Stroke Marking Menus in
    expert mode
  • As Efficient as Compound Marking Menus in novice
    mode
  • usable with small screens
  • Future Work Formalization of menu properties
