L9 Virtual Reality Flashcards
VR in Rehabilitation
- More actions: execute actions that they cannot perform in
real life due to their disabilities - More practice: in addition to traditional therapy
- Individualized treatment plans: developed on the basis
of careful assessment and following case-by-case treatment
goals - Analysis: better understand the needs of people with
disabilities in public places and at home - Convenience
VR Platforms
Google Daydream, Life VR (Time Inc.), Windows Holographic,
PlayStation, Xbox, HTC Vive, Oculus Rift,Hololens, Samsung Gear
Displays
Head mounted display (HMD), monitors, 3 monitors, cylindrical screens
(180º, 360º ), domes (CAVE)
Input Devices
Mouse/keyboard, wand, joystick, audio input, cyber glove
Interaction Mechanisms
head tracking, eye tracking, full-body tracking – motion
capture, real devices (gun), dynamics (treadmill, moving platform), user interfaces
Platform Considerations
- Ease of Software integration
- Realism/Immersion
- Integration into users’ lifestyles
- At home or for use in clinics
- Connectivity to other users
Display Considersations
- Realism/Immersion
- Cost
- Space/Size
- VR sickness
- Sensitivities
Input Device Characteristics
- Size and shape, encumbrance
- Degrees of freedom: integrated (mouse) vs. separable (Etch-a-sketch)
- Direct (natural) vs. Indirect Manipulation
- Rate control vs. Position control
- Relative vs. Absolute
Relative: measure difference between current and last input (mouse)
Absolute: measure input relative to a constant point of reference (tablet)
Augmented Reality
live direct or indirect view of a physical, real-world
environment whose elements are augmented (or supplemented) by computer-generated
sensory input such as sound, video, graphics or GPS data.
Benefits of Immersive VR
Therapy
- Improved trunk control and limb use
- Improved balance, mobility
- Improved fine and gross motor movement
- Enhanced cognitive and executive functioning
- Motivation: Gaming effect
- Feedback: visual, audio, tactile/haptic
- Greater sense of confidence and empowerment
Virtual Reality for Rehab Therapy
- Post-Op
- Stroke
- Spinal Cord Injury
- Accident
