A Novel Active Heads-Up Display for Driver Assistance

Abstract

Abstract-In this paper, we introduce a novel laser-based wide-area heads-up windshield display which is capable of actively interfacing with a human as part of a driver assistance system. The dynamic active display (DAD) is a unique prototype interface that presents safety-critical visual icons to the driver in a manner that minimizes the deviation of his or her gaze direction without adding to unnecessary visual clutter. As part of an automotive safety system, the DAD presents alerts in the field of view of the driver only if necessary, which is based upon the state and pose of the driver, vehicle, and environment. This paper examines the effectiveness of DAD through a comprehensive comparative experimental evaluation of a speed compliance driver assistance system, which is implemented on a vehicular test bed. Three different types of display protocols for assisting a driver to comply with speed limits are tested on actual roadways, and these are compared with a conventional dashboard display. Given the inclination, drivers who are given an overspeed warning alert reduced the time required to slow down to the speed limit by 38% (p < 0.01) as compared with the drivers not given the alert. Additionally, certain alerts decreased distraction levels by reducing the time spent looking away from the road by 63% (p < 0.01). Ultimately, these alerts demonstrate the utility and promise of the DAD system.

Driver classification and driving style recognition using inertial sensors

“…[12], [13], [7] By looking at the driver inside the vehicle, we can learn where a driver positions his/her hands, how fast and how wide he/she moves his/her head to examine the surrounding situation, and any changes in over all body posture [4], [6]. Using these as additional features will go a long way towards understanding driving style and intent so robust and reliable active safety and driver assistance systems can be designed [2], [3].…”

“…The definition in (1), (2), and (3) only segments the inertial data. Whereas the data defining acceleration and braking events only use longitudinal accelerometer, data defining the turning events use both gyro and longitudinal accelerometer data.…”

Robust and continuous estimation of driver gaze zone by dynamic analysis of multiple face videos

“…Consequently, there is a great potential for human-centric intelligent driver assistance systems [5], [6], [7], [8] to alert or even guide [9] the Authors are with the Laboratory of Intelligent and Safe Automobiles (http://cvrr.ucsd.edu/lisa/), University of California, San Diego, La Jolla, CA, USA {atawari, mtrivedi} @ucsd.edu driver briefly through the critical situation. Monitoring driver behavior is, hence, becoming an increasingly important component of an Intelligent Driver Assistance System (IDAS).…”

Pedal error prediction by driver foot gesture analysis: A vision-based inquiry

“…There is a laser based head-up display which can display visual cues anywhere on the windshield. More details on the heads-up display can be found here [14]. Two speakers were also used to generate audio cues when needed.…”
