Virtual Reality Can Enhance a Wide Array of Research Studies
You can use VR to present immersive environments or test virtual iterations of a product, and measuring physiological responses adds lots of information that expands analysis and understanding.
Are you setting up a virtual reality study? BIOPAC can provide VR/Immersive Solutions with Physiology Data, including options for multi-modal stimulation (visual, auditory, olfactory, haptic, and electric), programmable stimulation, automated event marking & scoring, and more.
How VR Can Improve Marketing Research. Watch the interview from Neuromarketing World Forum (in English):
How to Integrate BIOPAC Data into the Virtual World | Multi-signal, Multi-subject Streaming in Vizard This example shows how to stream fNIR data and physiological data (heart rate) from four participants using tools in COBI, AcqKnowledge, and Vizard:
How to Setup Network Data Transfer (NDT) in AcqKnowledge and Vizard
How to Create a Stimulus Presentation Paradigm in VR | In this example, food items are presented, but the paradigm can be modified for other stimulus presentations:
The program starts and stops AcqKnowledge (ACQ) automatically. Simply load all 3D model files in the stimuli subfolder and then randomize the order of object presentation. Pre-loads all models in the queue to reduce lag. When an object is grabbed, a marker is sent indicating the object name. Mean and minimum distance to object for each trial are reported as markers in ACQ. Sending markers to ACQ is optional and set in a variable.
HMDs and Additional Sensors for fNIRS and B-Alert Head mounted displays (HMD) are often utilized in virtual reality protocols. Measures such as fNIRS, EEG, Cognitive State, and Workoad use sensors that 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. The comfort and fit of multiple HMDs with additional sensor(s) was tested.
VizMove PRISM all-inclusive projection VR PRISM is an enhanced, immersive, simulation theater that enables you to add situational awareness skills to training with software, hardware, installation, training, physiological measures, and support. Immerse trainees in specific, realistic scenarios to improve preparedness without exposure to hazards. Synchronize events in the training with physiological measures (ECG, RSP, EDA, EEG, fNIRS, etc.) to assess the individual’s response. VR PRISM Info Sheet
Script 060 – Dynamometry Feedback | MVC line trace A participant records a signal (MVC from a dynamometer in this example) and then approximates the target path as closely as possible. A text file is produced with both the target path data and the approximation data so it can be loaded and analyzed in AcqKnowledge.
