AI summary
A user's visual health can be evaluated via a virtual reality (VR) system, which can include a VR headset in electronic communication with a computing device. The computing device causes virtual environments, which can include objects, to be displayed on the VR headset. Using varying combinations of eye-tracking sensors, eye-tracking cameras, motion-tracking sensors, handheld devices, and microphones, the VR headset collects data about the user as she focuses on various objects displayed in different positions in the virtual environments. Optionally, advanced algorithms in the computing device can dynamically alter the positions of the objects and analyze a degree to which the user focuses on the objects and transitions between near and far focusing to evaluate the user's focusing ability. This dynamic evaluation can facilitate a wider scope of testing and a more detailed assessment of the user's ocular health, as compared to traditional ocular evaluation methods.
