Aim of the “Subliminal Perception in Cars”-Workshop
The aim of this workshop is to discuss the potential and possible application of subliminal techniques employed to counteract the problem of limited cognitive abilities and bounded attention of a driver. To alleviate the cognitive load associated with the interaction with the variety of emerging IVIS/ADAS in addition to the driving task, we assume that subliminal techniques offer high potential to significantly reduce the amount of information to be processed simultaneously. These cues should be provided using appropriate modalities (visual, auditory, tactile/haptic, olfactory, etc.), following the specific nature of the task to fulfill, and according to a driver’s abilities. As research and discussion on subliminal techniques would benefit from a significant collaborative effort from a range of disciplines like engineering, neuroscience, computer science, psychophysiology, we invite researchers from these fields to submit their position paper and participate in the workshop. We are sure that the approach provides exciting challenges, which will significantly impact on society at large, making significant contributions toward a more natural, convenient, and even a relaxing future style of driving.

Topics of Interest
Potential topics to be covered in position papers and discussed at the workshop include, but are not limited to
* Taxonomy (definition, terminology) of terms implicit, subliminal, supraliminal, priming, conscious, preconscious
* Philosophy or rationale for the use of subliminal interfaces
* How to reduce “risk” in subliminal interfaces?
* Socio technical issues, e.g., social acceptance and/or aversion/repulsion about this type of technology?
* How fast do people perceive information presented in a subliminal way? Is it fast enough to be used in a vehicular setting?
* Is the perceived information difficult to interpret?
* Is there an influence on individual differences like age, gender, intelligence, characteristics, abilities and disabilities, cognitive style, cultural differences, etc.?
* Evaluation techniques for the perception of subliminal information
* What, if any, is the impact of information communicated subliminally to further information submitted explicitly?
* What differences in “dual information presentation” using subconscious and conscious channels can be discovered?
* Is a replacement of consciousness by subliminally delivered information directly results in an increase in road safety?
* Is a impact of subliminally delivered information discoverable on the cognitive load or perceived workload (e.g., NASA TLX)?
* What are appropriate subliminal techniques for workload reduction while driving? More specific, a) Unobtrusive way of drivers’ state detection (e.g., facial expression detection, grip strength detection, etc.), b) Subliminal display of drivers’ state or adaptive interfaces (dynamically changing contents and/or formats of visual display, sonification (of EEG, alpha wave), etc.), c) Mitigation or regulation interfaces (speech-based interfaces or driving coach, mitigation using music, fragrances, etc.)
* Subliminal interfaces for the automotive domain (head-up displays, vibro-tactile transducers, olfactory stimulation, brain-computer interfaces (BCI))
* What are characteristics of subliminally delivered information (e.g., reachable bandwidth, natural bounds, complexity of information, speed of perception, appropriate modalities, strength/duration/frequency of subliminal interaction)?
* Potential of subliminal cues to guide a driver to the right course of action or to a specific emotional state?

    I am running a workshop for my CTSO conference, one designed for middle schoolers. My CTSO focuses on business, what are some good ideas for topics and how should I run the workshop?
