Buzz Buzz: Haptic Cuing of Road Conditions in Autonomous Cars for Drivers Engaged in Secondary Tasks
HCI Today summarized the key points
- •This article explores whether drivers’ situation awareness can be maintained during automated driving using haptic cues.
- •The study was designed to test whether haptic information—avoiding voice and visual channels—helps drivers who are deeply engaged in a secondary task.
- •In a Level 4 autonomous driving simulator, participants played Fruit Ninja, and the researchers compared questions about road and traffic conditions with eye-gaze behavior.
- •Participants who received haptic cues had more correct answers and looked at the screen less; the cues did not significantly interfere with the task, and device satisfaction was also higher.
- •Overall, haptic cues may help preserve drivers’ situation awareness during automated driving while they maintain a secondary task, and further discussion is needed for real-world deployment.

Why Read This from an HCI Perspective
This article is highly meaningful for HCI/UX practitioners and researchers because it experimentally demonstrates how drivers’ situation awareness can be maintained during automated driving, and whether such intervention can avoid disrupting secondary tasks. In particular, it shows the applicability of Multiple Resource Theory—using haptics to convey information when visual and auditory channels are already occupied—and offers useful design insights into how the method of information delivery affects attention allocation and task switching.
CIT's Commentary
The core of this research is not whether it provides drivers with more information, but whether it can restore the necessary state without harming the context of other tasks they are currently doing. Haptic channels are often underutilized compared with visual and auditory channels, which makes them promising candidates for reallocation designs in environments where spare resources exist—such as during automated driving. However, tasks like Fruit Ninja may involve limited cognitive load, so additional validation is needed to confirm whether the same effects can be reproduced in real mobile use or work-oriented secondary tasks. It is also important to look beyond short-term accuracy: we should examine whether improved situation awareness extends to warning interpretation, intervention timing, and trust formation. From a practical standpoint, the success of implementation may hinge on how intuitively drivers can learn the meaning of haptic patterns and how well the system can accommodate individual differences in sensitivity.
Questions to Consider While Reading
- Q.When the type of secondary task and its cognitive load level vary, how far will the effectiveness of haptic cues remain?
- Q.Can we verify whether improvements in situation awareness also translate into better takeover performance or faster reaction times?
- Q.Considering the learnability of haptic patterns and individual differences, what is the appropriate design for distributing some information to haptics and other information to different channels?
