ABSTRACT
The contribution of tangible and intangible feedback is compared for
virtual tactile car Human-Machine Interfaces (HMI) design, to measure their
performance both in static conditions and while driving. A subjectively
calibrated transparent glass provides tangible passive haptics, and visual cues
are used to study sensory substitutionbased intangible interactions. The
results show that the performance of the subjects was significantly improved in
driving conditions as they interacted faster, more accurately and with a higher
satisfaction. In addition, our findings highlight that the contribution of
tangible systems is significantly lower in driving conditions, raising new
questions about the nature of haptic modalities in the function of the context
of use. This study provides additional knowledge about the influence of dynamic
environments and external tasks on haptic perception.
