Application

Design takeaway

When designing therapeutic devices, integrate virtual and physical models to enhance user experience and functional outcomes, while rigorously testing for usability and safety.

How to apply

Designers can use VR to create realistic simulations of desired movements and couple them with physical feedback mechanisms (like exoskeletons or haptic devices) to enhance user engagement and learning in various applications, from therapy to training.

Project actions

  • 01Consider using VR to simulate a task or environment for a product.
  • 02Explore how physical feedback (e.g., resistance, vibration) could enhance a VR experience.
  • 03Think about how to measure user engagement or the 'feeling' of using the product.

Method & Evidence

AimTo assess the acceptability, usability, and embodiment of a novel VR-based mirror therapy system with an actuated exoskeleton for hand motor impairment recovery.
MethodExperimental study with user testing.
ProcedureHealthy participants tested three different working modes of the VR mirror therapy system, which included a soft hand exoskeleton. Acceptability and usability were measured using the System Usability Scale (SUS), simulator sickness was assessed via the Simulator Sickness Questionnaire (SSQ), and the sense of embodiment was evaluated using a customized questionnaire.
Sample21 participants
ContextRehabilitation and physical medicine, specifically for hand motor impairments.

Variables

IV["Working modes of the VR mirror therapy system (three modes tested)."]
DV["System acceptability (System Usability Scale).","Simulator sickness (Simulator Sickness Questionnaire).","Sense of embodiment (customized questionnaire)."]
CV["Participant health status (healthy users).","Duration of system use (implied, not explicitly stated as varied).","Environmental conditions during testing (assumed consistent)."]

Strengths & Limitations

Strengths

  • +Innovative integration of VR and exoskeleton technology.
  • +Use of established and customized questionnaires for robust evaluation.

Limitations

Testing with healthy participants may not reflect the experience of those with actual impairments. The study focused on short-term acceptability and usability, not long-term therapeutic benefits.

Reliability & validity

The use of established scales like SUS and SSQ contributes to the validity and reliability of the findings regarding usability and sickness. The customized questionnaire for embodiment might require further validation. Testing with healthy individuals limits the generalizability to patient populations, affecting external validity.

Think critically

How might the cost and complexity of such integrated VR and exoskeleton systems limit their widespread adoption in clinical settings, and what alternative modelling approaches could achieve similar benefits with lower barriers to entry?
