Accuracy of Oculus Touch Controllers for Rehabilitation and Biomechanical Applications
ABSTRACT
Background:
As commercial position tracking technology becomes more readily available, it is necessary to evaluate the accuracy of these systems prior to using them for biomechanical and/or motor rehabilitation applications.
Objective:
A study was performed to evaluate the relative position accuracy of the Oculus Touch controllers in a 2.4 x 2.4 m play-space.
Methods:
Data points were acquired at varying step sizes along the play-space floor in the X (width), Y (height), and Z (depth) directions using caliper measurements and physical blocks.
Results:
It was found that the average position accuracy error of the system was 0.95±0.65 mm or 2.24±2.01% when normalized to step size. An average noise value of 0.036 mm was determined.
Conclusions:
A comparison of these values to cited visual, goniometric, and proprioceptive resolutions conclude that this system is viable for tracking upper limb movements for biomechanical and rehabilitation applications. The accuracy of the system was also compared to accuracy values from previous studies using other commercially available devices and a multi-camera marker-based professional motion tracking system.
