Human Perception on Medical Extended Reality Devices

Completed · Not applicable

Conditions studied: Healthy

In brief

The proposed research will collect participant's responses that respond to questions about visibility of certain signals on an immersive mixed reality environment. These responses will be used to assess Head Mounted Display (HMD) quality and task performance. Other collected data may be included such as response time and eye movements. Responses will be collected via an FDA application designed to work with a wide range of HMDs and able to display both 2D simple scenes and 3D complete scenes. This application allows a human observer to look at a signal (sinusoidal, disk, sphere, etc.) on a synthetic noisy background or a realistic 3D scene both in virtual reality and augmented reality immersive environments. The application will also provide instructions and a response interface for the observer to respond to questions related to the visibility and to gather task performance measurements. Participants will not be asked to complete tasks that require specific training or skills. Any adult human with normal or corrected-to-normal vision that can wear an HMD is eligible to participate in this experiment. Data collected will not include identifiable information. FDA will perform participant enrollment and data collection, ensuring management of PII in accordance with federal rule. Participants will be recruited at will and in person, using promotional materials only containing language within this document. Participants will sign the attached consent form either electronically or by hard copy.

Who can join

Age: 18 and older, up to 70. Sex: any. Healthy volunteers: accepted.

You may qualify if…

Must be between 18 and 70 years old
No gender requirement
No sensory, proprioceptive, or neural impairments
Ability to sit for 20-30 minutes at a time, for up to 2 hours with 5-10 minute breaks
Adults with normal or corrected-to-normal vision that can wear an HMD comfortably.
For participants with corrected-to-normal vision and, in the case of an HMD that is not compatible with glasses, contact lenses will be required

You may not qualify if…

History of light sensitivity, epilepsy, or seizures
Uncorrected visual impairments
Pregnant women
Participants that have corrected-to-normal vision with glasses that cannot wear the HMD comfortably
Presence of sensory, proprioceptive, neural, vestibular, or physical impairments that limit fine motor control, gross movement, normal ambulation, or ability to sit/stand as needed for the study
Claustrophobia such that use of an HMD induces anxiety or other negative psychological response
Cognitive impairments that limit the ability to comprehend simple written and verbal instructions or identify and locate objects in space
Subjects with migraine headaches or that experience motion sickness
Current or prior diagnosis of epilepsy, seizure disorder, dementia, migraines (especially with visual aura), or other neurological diseases
Current medical condition predisposing to nausea, dizziness, or vertigo (e.g. Meniere's disease)
Ongoing psychosis, hallucinations, or dissociative disorders affecting perception of reality
Hypersensitivity to flashing light or motion
Irritated skin or open wounds on the scalp and face where the AR/VR headset will rest
Past history of use of hallucinogenic medications (e.g. LSD, mesclun, etc.)
Prior cervical spine disorder or Brachial plexus disorder or shoulder joint disorder, or hand disorder or past surgery in any of the previous stated anatomic areas (as these might affect the use, responsiveness, and/or dexterity of upper extremities or hand-eye coordination)
Subjects will be excluded from participation in this study if they answer yes to a screening question about taking various medications listed below: (n.b. the reasons for subject being excluded is also noted with the potential side-effects of the noted medication)
Antihistamines (e.g. diphenhydramine {Benadryl}, etc.) -- Drowsiness, dizziness, constipation, stomach upset, blurred vision, or dry mouth/nose/throat may occur.
Muscle relaxants (e.g. methocarbamol {Robaxin}, cyclobenzaprine {Flexeril}, carisoprodol {Soma} , etc.) -- Drowsiness, tiredness, clumsiness, headache, dizziness, lightheadedness, dry mouth, stomach upset, nausea/vomiting, or blurred vision may occur.
Analgesic medications (e.g. narcotics, Class II controlled substances such as propoxyphene {Darvon} , etc.) -- Low blood pressure, drowsiness, fainting, dizziness, nausea, vomiting, generalized weakness, a feeling of general discomfort called malaise.
Sleep medications (e.g. zolpridem {Ambien}, etc.) -- Daytime drowsiness, dizziness, weakness, feeling "drugged" or light-headed; tired feeling, loss of coordination; memory loss, stuffy nose, dry mouth, nose or throat irritation; nausea, constipation, diarrhea, upset stomach, headache, muscle pain, anxiety, depression, aggression, agitation, confusion, or hallucinations (hearing or seeing.) This is not a complete list of side effects and others may occur.
