Description

Vehicle-mounted font evaluation method, vehicle-mounted information system and vehicle Technical Field The application relates to the technical field of vehicle control, in particular to a vehicle-mounted font evaluation method, a vehicle-mounted information system and a vehicle. Background With the increase of the quantity of the vehicles in society and the vigorous development of the automobile industry, the structural form of the vehicle-mounted information system is also diversified and developed. In the in-vehicle information system, font design is an important factor affecting the operation efficiency of the driver, visual attention allocation, and driving safety. In the related art, the evaluation method of the vehicular fonts depends on subjective questionnaires and user interviews. However, it is difficult to form a uniform rating standard because there may be a large difference in the feelings of different users participating in a questionnaire or interview to the same in-vehicle font.
