The HALIOS® multi purpose optical sensor is based on
an optical bridge which provides a contactless detec-
tion of gestures (e.g. movement of a finger). The IC
E909.05 processes data from optical reflections of an
object in front of the sensor using a system called HAL-
IOS® (High Ambient Light Independent Optical System).
HALIOS® is highly efficient suppressing ambient light
and also has an inherent self calibration capability to
eliminate disturbances caused by housing reflections
such as dirt or scratches.
New intuitive user interfaces are possible with this
unique input device. All data is analyzed and evaluated
internally with a high performance microprocessor and
the data output can be easily customized.
HALIOS® devices can be applied behind closed surfaces
which allows very flexible designs. HALIOS® firmware
provides all necessary algorithms and software based
filters.
