Paper Review: AR-Enhanced Workouts: Exploring Visual Cues for At-Home Workout Videos in AR Environment

DOI

Problem

• Hard to quickly learn the correct movements from the 2D video
• Failed to provide effective feedback

Solution

AR:

• Workout video centered in the user’s field of view
• Real-time visual feedback

Additional Camera:

• For the full-body status of the users
• Give feedback to adjust users’ movements in real-time

Design Space

Data:

• Motion-data:
  • The movements that users need to pay attention
  • Movement direction & sequence
• Non-motion data:
  • Goals that users only need to aim to achieve
  • Body skeleton (give feedback using joints)
  • Visual metaphors
    • Chair (where to squat)
    • Cone (height)

Task:

• Identification:
  • Key movement information -> better understanding
• Comparison:
  • Apply superposition
  • Overlaying users’ exercise performance onto standard visual cues

Situation:

• Address frequent viewpoint shifts
  • Floating screen (out of sight)
  • On-ground (within sight)
