Subjective perceptions when using motion tracking systems – a comparison among healthy subjects, individuals post-stroke, and therapists
نویسندگان
چکیده
Different tracking technologies allow users to interact with virtual reality environments. Most research regarding tracking systems has focused on studying their performance parameters, mainly accuracy. However, even though subjective parameters also determine the responses evoked by the virtual reality experience, least efforts have been made to study their influence. The subjective perceptions of healthy subjects, individuals post-stroke, and physical therapists after using three tracking technologies (optical, electromagnetic, and skeleton tracking) to interact with a virtual rehabilitation exercise were collected via questionnaire. Results showed that subjective perceptions and preferences are far from being constant among different populations, thus suggesting that these considerations, together with the performance parameters, should be taken into account when designing a rehabilitation system.

Tracking Systems for Virtual Rehabilitation: Objective Performance vs. Subjective Experience. A Practical Scenario
Motion tracking systems are commonly used in virtual reality-based interventions to detect movements in the real world and transfer them to the virtual environment. There are different tracking solutions based on different physical principles, which mainly define their performance parameters. However, special requirements have to be considered for rehabilitation purposes. This paper studies and...

متن کاملIs perception of vertical impaired in individuals with chronic stroke with a history of ‘pushing’?
Post-stroke 'pushing' behaviour appears to be caused by impaired perception of vertical in the roll plane. While pushing behaviour typically resolves with stroke recovery, it is not known if misperception of vertical persists. The purpose of this study was to determine if perception of vertical is impaired amongst stroke survivors with a history of pushing behaviour. Fourteen individuals with c...
