Usability and UX of a Gaze Interaction Tool for Front Seat Passengers: Evaluation of a Gaze Controlled Optical Feedback System in a Car

Input modalities generally as well as in cars are evolving quickly regarding their spread and reliability. One possible input technique is gaze interaction, a topic still being researched. What are the front seat passengers' feelings towards gaze interaction, are they comfortable using it and do they think it is necessary? A laboratory experiment was conducted with 13 student participants, using a driving simulator, eye tracker, lamp and a driving wheel. Qualitative data was collected during and after the experiment through observation and a semi-structured interview. Quantitative data was collected through questionnaires (ATI, CTAM, SUS). The results were that the usability of the system was high but participants did not feel well using it.
