Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sensitivity and specificity of crHIT-vertical | 9 months | How many participants are correctly identified as either having a vestibular dysfunction or being healthy controls |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Subject discomfort - symptoms | 9 months | Number of subjects indicating motion sickness symptoms during the crHIT test. If motion sickness is present subjects are asked to rate the symptoms of motion sickness and severity on scale 1 to 5, where 1 is minimum and 5 is severe. |
| Subject discomfort - test apparatus | 9 months | Subjects rate the comfort of chair, head rest and goggle on scale 1 to 5, where 1 is very uncomfortable and 5 very comfortable. |
