Challenges of subliminal information displays in the car-context

To cope with the rising volume of information in vehicu-lar interfaces, explicit and attentive interaction is more and more replaced by implicit means of information exchange. This trend, supported by context- and activity-aware assis-tance systems, is still ongoing, requiring further solutions for reducing a driver’s cognitive load or level of attention. Subliminal interaction techniques are considered a promis-ing approach to deliver information or warning signals to the driver without causing any supplementary workload. This poster aims at discussing the potential of sublimi-nal (or subconscious) perception to improve the information flow for vehicle-to-driver interaction, and to specify research questions around this topic
