|Driver attention is a valuable commodity in
maintaining driving safety. However, with the
proliferation of many interactive devices that place
demands on the driver's attention while driving,
effectively allocating attention with the primary goal
of managing driving safety presents substantial
Our research investigates new techniques for proactive mediation of driver attention. We focus on ensuring that driving safety is maintained at all costs by directing the
|driver's attention towards upcoming events in the
driving scene if the driver is engaged in other
peripheral tasks such as cell phone conversation or
manipulating in-vehicle system controls.
As a first step in this project, we have investigated how the cognitive load imposed by conversing simultaneously during driving affects both driving performance and the conversation. Using a medium fidelity driving simulator, we looked at different types of conversation involving information assimilation, retrieval and generation while driving on routes composed of segments of varying levels of difficulty. The goal was to determine moments during driving where the driver attention could be effectively shared between driving and the secondary task of conversation could be allowed without negatively impacting driving, as well as understand moments where such sharing would present attentional challenges. Read details of this work here.
We have also investigated the effects of proactive mediation to direct the driver's attention towards critical driving conditions if the driver's attention is being shared by a secondary task such as cell phone conversations. We have looked at the effects of both long and short messages as well as forced suspension of conversations on the driving performance, conversation and how the mediation is perceived by the driver and the remote caller. Further details are available here.
We are looking towards developing and deploying systems that intelligently detect environmental conditions, infer driver's cognitive load and determine if, when and how to best intervene.
