Eye gaze input device
Realizing highly accurate eye gaze input by smart phone
Overview
This invention is related to the eye gaze detection and eye gaze input
device.
In conventional eye gaze detection and eye gaze input device, the
device needs to be installed in the environment or mounted on a
wearable device. However, those devices have certain limitation, such
as the position range where the function can be used for the former,
while the latter requires the user to wear the device.
This invention uses only a smartphone, and it is possible to run the
function of eye gaze detection and eye gaze input with 6 degrees
of freedom regardless of the user's standing position or the
environment area if the user holds the smartphone naturally [1].
In detail, the system estimates where the user is looking in the environment by combining the user's gaze direction detection using the smartphone's front camera and self-position estimation using the back camera/depth sensor and 3D map of the environment (acquired in advance).
59% less error than conventional technology*
Product Application
・Identify the target of interest by detecting the user’s eye gaze in
