Taking advantage of Virtual Reality technology in the context of research and practice can be a daunting task, given regulatory requirements and standards exacted by the medical device field. Evrisia(eh-VRIZ-ee-ah) comes from Electric Puppets - A Health Canada Class 1 medical device establishment licensed company that has created a tool called Evrisia that can jump start research and clinical applications for Virtual Reality in your hospital, clinic or research project.

Evrisia provides an interface that allows a clinician to interact with a Subject while they are in VR, with several controls over how the Subject experiences visual stimuli that surrounds them in a fully idealized virtual clinic. Their head, hand, eye movement and even pupil size can be recorded as they interact with the stimulus for later analysis by the clinician. VR based data visualization by a qualified clinician is an unprecedented way to review patient data- as opposed to simply looking at hand written notes on a long forgotten chart.

To begin with, we’ve created a series of Gold Standard derived medical vision tests in our first release including the Worth 4 Dot, Bagolini Striated Lens Test, Brock String, Acuity chart, Contrast sensitivity chart, Frisby, Farnsworth D-15, Synoptophore, and the Lees / Harms test. These tests are routinely used to determine Visual Acuity, Stereopsis, Eye functionality, and even assess brain functionality after trauma. We provide the stimulus, accurate measurement, and clinicians will have precise data to assess the condition.

All our systems come with Evrisia ART - a free program where a clinician can interact with a subject while they “paint” in VR with 3d objects. It is a great way to introduce any subject to a VR space and give them a sense of calm and control over their experience. Evrisia Art is also available as a free standalone in the Steam VR Store for HTC VIVE. We are currently working on Evrisia ART for Oculus Quest (and other Qualcomm XR based mobile headsets), and a small brochure about this particular project can be accessed here.

Pricing

Complete System:

For Clinicians, we provide a fully comprehensive set of tools that allows them to create protocols that place stimuli based on the included tests with several settings in any order they want. They have precise control over the visual environment, color filters, eye alignment, Interpupillary distance (IPD), and many other controls.

Software Pricing in clinic is $20,000 plus a license fee of $3500 per month.

Advanced System

For clinics that would prefer to use existing protocols to run tests as created by our team of Orthoptists, Opthalmologists, and Optometrists, we provide the “Advanced” system where some controls may still be applied but protocols may not be edited. This will be useful for clinics who only practice assessment and do not design their own testing protocols, or researchers who only wish to use the suite of gold standard tests according to their pre-prescribed instructions.

Software pricing for this system is $5000 plus $500 per month as a license fee, and each additional protocol set costs $1000 for us to prepare and send to you.

Simple/Home/Community system

For community centres working with local clinics who have a full system, our software is available for $500 per installation license fee. These systems are pre-setup to general specifications. To customize them for a specific patient an additional fee of $250 is applied. This will allow individual patients to do routine data capture in VR regularly at home, and they can send the resulting digital files to their doctor for assessment on the clinical system.

Additional fees for training, setup, and ongoing support are applicable where appropriate. Generally monthly online support/training for up to 3 to 4 hours per system will cost $400.

Hardware Requirements:

Compatible system is the HTC Vive with Eye Tracking. (VIVE PRO EYE, or VIVE PRO with Pupil Labs are currently supported but must be purchased separately) Bear in mind these systems cost approximately $2000 for the PC, $1000 for the VIVE, and if required $3500 for the Pupil Labs eye tracking.

We are currently working on a solution that works with Qualcomm VR systems and a less expensive PC and anticipate these to be ready by the summer of 2020. VR systems of this nature are predicted to cost as little as $600 and the PC requirement should be much lower - as little as a $200 PC.

Custom Tests

If your research project has specific stimuli required that isn’t included, our tests are all created with a UNITY 3d template that we can provide you, or we can create them for you based on your specifications. Contact us for more information on what is required and the costs involved, as they vary considerably depending on the stimulus you require. Stimulus can be as simple as a floating cube, or as complex as a fully animated scene with story and interactive elements, so pricing obviously varies considerably as well.
