Haptic Blind Spot Alert System
In everyday driving, the issue of blind spot collisions are a prevalent issue. Currently, there are blind spot detection systems available as factory accessories to manufacturer specific vehicles, but aftermarket detection systems are scarce. Blind spot detection systems all share a common feedback to the driver: visual and/or audio. In this project, a haptic feedback steering wheel cover was used in conjunction with ultrasonic sensors to monitor blind spots. This provides a better alternative to a blind spot alert system by adding haptic feedback. A preliminary study was performed on human subjects to analyze their response times to different haptic alerts to ensure the most beneficial stimuli is used on the blind spot alert system. However, different modes of vibration showed no significant difference in response time, so the stimuli was chosen in terms of user preference. Subjects explained that they felt a slow pulsing vibration was more effective and distinguishable than a steady vibration. Click here for his paper.
