8.3.1.1 Gap analysis

Required improvement for the use of eye gaze trackers in automotive environment includes:
– Commercial eye gaze trackers which have not yet been tested for automotive compliance
– Robust algorithm for affective state detection
– Improving accuracy and latency of commercial eye gaze trackers in automotive environment

– Combining eye gaze control system with other existing modalities
– Testing the accuracy of driver distraction and affective state detection system in automotive
environment.
8.3.2 Use case – Gaze tracking

A dynamic HMI responds to the user's gaze. Elements of the UI can be configured to change based
on whether or not the user is looking at them. For example, an element on the screen can be set to be
transparent when the user is not looking at it, and immediately return to the visible state once the user
is looking at it.
Controlling the vehicle multimedia by eye movement can be implemented to improve driving safety.

8.3.2.1 Requirements

R1: Accuracy and latency requirement for gaze control system integrated for use in the HMI of a
VMS shall not require fixating attention for more than 2 seconds or the maximum time defined by
local regulations in automotive environment on the HMI.

8.3.3 Use case – Controllable camera through eyes
Users can also control an external camera through their eyes, which is similar to the head-tracking
camera.
NOTE – This is not a DVR camera which is mandated in certain country to record. DVR camera are not user
controllable.
