Package hmi.sensors.eyebox2 Description

API for accessing the Xuuk EyeBox2 eye contact sensor. This package provides direct access to the information that the Xuuk application gives us (see Section directaccess). In addition, it allows one to more reliable, calibrated information about eyecontact (see section calibratedaccess)

The sensor

The sensor: what is it, and why is it useful.

Direct sensor access

What does xuuk provide in its telnet API? reference to relevant functions in package.

Calibrated access

- what is wrong with default xuuk info? there is a lot of inaccuracy in reported events. So one cannot assume that messages are true. Not looking still gives look-events and vice versa. - how to improve? we can of course measure how many wrong events are sent by xuuk sensor in different user-positions/looking situations. subsequently, given a history of recent events, we can calculate the probablity that the user is looking within a radius n with confidence c given the current sensor history h. reference to relevant functions in package. description of calibration routines for new demo setups.
