Head mounted displays (HMD) are often utilized in virtual reality protocols. Measures such as fNIRS, EEG, and Cognitive State are also useful, and sensors for such measurements must be placed on the participant’s head along with the HMD. Maintaining participant comfort as well as field of view is critical for such studies to provide meaningful results.
BIOPAC has a unique solution for using fNIRS under a VR helmet. Due to the very thin and flexible sensor design, our fNIRS sensor fits comfortably under most head-mounted displays. See above how the sensor fits with the Oculus Quest 2, VIVE, and HP Reverb G2 Omnicept. In addition, our wireless fNIRS system allows for the fNIRS Imager device to be worn on the upper arm, eliminating the need to placed extra hardware on the head. You can even combine fNIRS and a B-Alert X Series wireless EEG headset for untethered, lightweight measurement. Additional benefits of using BIOPAC’s fNIRS solution in VR include real-time streaming of oxygenation and raw data to the virtual environment to enable neurofeedback.
The comfort and fit of an HMD with additional sensor(s) was tested.
Popular HMDs include HP G2, Oculus Quest 1 and 2, Rift S, Varjo, and Vive. Three were selected for this test, additional HMD units will be added as testing goes on.
fNIRS and B-Alert sensors did not block the field of view of an individual wearing either device in a VR headset.
They all fit relatively comfortably under all three headsets.
Use to measure clench force in the MRI; clench force range 0-50 kgf. The lightweight, ergonomically designed transducer provides direct readings in kilograms or pounds. Use in isolation or combine with EMG recordings for in-depth studies of muscular activity. The isometric design improves experiment repeatability and accuracy. The TSD121B-MRI has an 8 meter cable terminated for connection […]View All
