Introduction
With the continuous development of intelligent vehicles, HMI has become more and more important, and automobile manufacturers pay more and more attention to the user experience. I made an inventory of human factors included in automotive HMI design from four parts: sensory, cognitive, decision-making and automation. Interested friends, let's have a look.
Driving is an information processing activity. During the driving process, the driver continuously obtains and processes information from various sensory channels to make decisions and take appropriate actions to control vehicle.
Senses
1. Vision
Vision
The ability of the eye to distinguish objects is called vision, and vision is divided into static vision and dynamic vision. Static vision is the vision of the driver when the driver is still, and dynamic vision is the vision of the driver during the movement of the car. When people with normal vision are observing distant objects, their motor vision decreases rapidly with the increase of speed. For example, when the vehicle speed is 60km/h, they can clearly see the traffic signs at 240m; when the vehicle speed is 80km/h, they can only see clearly traffic sign at 160m. In addition, according to NHTSA2010-0053, the driver's line of sight cannot leave the road ahead for too long, and 2 seconds is a recognized safety time limit.
Field of vision
The field of view refers to the range that can be seen on both sides of the gaze point when both eyes are fixed on a target. The size of the field of view is related to the speed of the vehicle. As the speed of the vehicle increases, the driver's field of vision becomes significantly narrower. For example, when the vehicle speed is 40km/h, the field of view is 90° to 100°; when the vehicle speed is 80km/h, the field of view is 60°. Useful Field of View (UFOV) refers to the diameter of the continuous eye movement between different gaze centers. Within this viewing angle range, all existing targets can be viewed. UFOV has been proven to be related to vehicle collision risks, obstacles object collision and tendency to fall.
Color
The recognition and feeling of different colors by people is called color sense. People react differently to different colors. For example, red light is highly visible and irritating, making people alert; yellow light has the highest brightness and the highest reflected light intensity, which is easy to arouse people's attention; green light is softer, giving People feel calm and secure. Therefore, in traffic engineering, red light is used as a no-go signal, yellow
