Sensor Tracks Eye Movements in Real Time to Enhance Virtual Reality

A sensor that can detect the tiny electrical signals generated by muscles as
someone moves their eyes could offer split-second control over virtual or
augmented reality systems.

A team of researchers from Belgium and the Netherlands has developed a sensor
that can detect eye movements in real time using an array of electrodes. The
researchers say the technology could enable videogamers to interact with the
screen by controlling cursors with their eyes to navigate through menus and
select different options, or to open and close applications. In addition, the
technology could provide feedback to the game on how the user is reacting to
their virtual surroundings, according to Carlos Agell at the Belgium-based
IMEC innovation center. The team developed a system based on four electrodes,
which are built into the glasses around each lens, at points where the frames
touch the skin in order to collect electrical impulses emitted by the eye.
Agell says the algorithm translates the signals into a position, based on the
angle the eye is making with its central point of vision.
