Textual input in VR

  • Browsing
  • Texting
  • Creating profiles
  • Chatting
  • Inputting login information
  • Contact forms
  • Commenting

Existing input methods

  • Independence from

controller

  • Fastest 15 WPM
  • Natural
  • Body engagement
  • Least fatiguing

Fatigue Lack of feedback Need for focused vision

  • Fatigue
  • Lack of feedback
  • Fatigue
  • Lack of feedback
  • Greater space

requirements

  • Fatigue
  • Lack of feedback
  • Fixed position of

hands

  • Slow
  • Frustrating
  • Unnatural mapping
  • f keys

Layout Variations

  • Familiar
  • Frequency of individual pairs ignored
  • Not familiar
  • Statistical travel distance between

keys optimized

User Tests

  • 6 participants (21.75 YO)
  • 2 Sessions
  • Speed and accuracy are measured by counting WPM speed and Error

rate

  • In order to measure fatigue, standard NASA TLX survey is used
