Swedish firm Tobii on Monday announced plans to raise 450 million crowns ($50 million) in a rights issue to invest in technology for virtual reality and smartphones.
The company's eye-tracking technology helps disabled people use computers by identifying where they are looking on their screens.
Dell, Acer and MSI have already released computers that integrate Tobii's eye-tracking sensors, and some 40 games with support for Tobii's technology have been launched.
Tobii's system uses invisible infra-red light to illuminate the eyes. Camera sensors capture the reflection off the retina and cornea to gauge where the eye is, and where it is looking.
In a sign of the technology's increasing importance, Alphabet Inc's Google bought eye-tracking firm Eyefluence last month.
