Use in health assessment

As a biomarker, eye tracking plays a significant role in providing data-based analytics for use in health assessments. Specifically, eye tracking can provide the analytics to develop new methods of detecting neurological conditions and diseases as well as vision impairments.

What Tobii Ocumen delivers

Tobii Ocumen delivers gaze vector data streams separately for each eye, which, for example, could be leveraged in an assessment application for amblyopia (lazy eye) — one of the leading causes of vision impairment in children.

Tobii Ocumen delivers pupil diameter separately for each eye. This data could serve as an additional biometric in assessing cognitive load and fatigue as well as traumatic brain injury — enabling the development of advanced VR applications that provide clinical staff with assessment support.

Use in therapeutics

The mobility and relatively low cost-level of VR compared with traditional therapeutics has led to a rise in VR applications designed to cure vision impairments, overcome fears, and address trauma.

Tobii Ocumen delivers accurate eye movement and pupil size measurements enabling an application to identify minute changes in user reaction — enabling the development of advanced VR applications that provide therapists with detailed feedback and patients with convenient therapy.
