Prompt Description

A2' Warm Color (Medium-High Risk): Suitable for medium to high-risk scenarios (lane departure, preceding vehicle deceleration). RGB Value: (255, 204, 0) Information Entropy: 1.2-1.5 bits/pixel (retains core information) Screen Coverage: 25-30% (does not obstruct too much vision) A3' High-Alert Full Screen: Suitable for extremely urgent scenarios (collision warning, emergency avoidance). RGB Value: (255, 0, 0) Information Entropy: ≤0.5 bits/pixel (core warning information only) Screen Coverage: 80-100% (forced attention capture) B2' Medium-Frequency Alert: Suitable for medium to high-risk scenarios (lane departure warning, preceding vehicle hard braking warning). Frequency Range: 1500-2000Hz Center Frequency: 1750Hz Volume: 70-75 dB SPL (5dB higher than low-risk level) Rhythm: 200ms interval, 150ms duration (more urgent than low-risk level) Waveform: Trapezoidal wave (rapid rise) Rise Time: 3ms, Fall Time: 10ms B3' High-Frequency Urgent: Suitable for extremely urgent scenarios (collision warning, emergency avoidance instructions). Frequency Range: 2750-3750Hz Center Frequency: 3250Hz Volume: 80-90 dB SPL (5-10dB higher than low-risk level) Rhythm: ≤30ms interval, 80ms duration (extremely urgent) Waveform: Square wave (instantaneous change) Rise Time/Fall Time: ≤1ms C2' Medium Vibration: Suitable for medium to high-risk scenarios (lane departure reminder, preceding vehicle hard braking reminder). Amplitude: 1.0-1.4mm (average 1.2mm) Frequency: 175-225Hz (average 200Hz) Duty Cycle: 80% (750ms vibration, 188ms silence) Duration: 750ms continuous vibration Application Position: Steering wheel as a whole Tactile Threshold Multiple: 4.0× (clearly perceived, arousing alertness) Vibration Acceleration: 2.0-3.5 m/s² C3' Strong Vibration Pulse: Suitable for extremely urgent scenarios (collision warning, emergency avoidance instructions). Amplitude: 1.8-2.2mm (average 2.0mm) Frequency: 275-325Hz (average 300Hz) Duty Cycle: 100% (1000ms continuous vibration, no silence) Duration: 1000ms continuous vibration Application Position: Steering wheel + seat dual position (synchronized vibration) Tactile Threshold Multiple: 8.0× (forced awakening) Vibration Acceleration: 4.0-6.0 m/s² Vibration Intensity: Produces strong discomfort, forcibly awakens Experiment Number Visual Modality Auditory Modality Tactile Modality Scene Type Subject Allocation H1 A2' HSV(35°,70%,90%) Information Entropy 1.2-1.5 Screen Coverage 25-30% B2' 1750Hz±300Hz 70-75dB SPL 200ms interval 150ms duration Trapezoidal wave C2' 1.2mm amplitude 20"
