Evaluating informative auditory and tactile cues for in-vehicle information systems

Yujia Cao, Frans van der Sluis, Mariët Theune, Rieks op den Akker, Anton Nijholt
2010 Proceedings of the 2nd International Conference on Automotive User Interfaces and Interactive Vehicular Applications - AutomotiveUI '10  
Vibration was found to be a promising alternative for sound to deliver IIC, as vibration cues were identified more accurately and interfered less with driving.  ...  Both sound and vibration cues were created for four different priority levels and tested in 5 task conditions that simulated possible perceptional and cognitive load in real driving situations.  ...  At this step, the evaluation was only focused on the design of cues. It did not involve the IVIS messages or the attention management  ...

2018 Proceedings of the 2018 CHI Conference on Human Factors in Computing Systems - CHI '18  
In this paper, we extend the timing stimulus through auditory and tactile cues.  ...  Our results demonstrate that audio timing through voice commands and haptic timing through tactile cues on the hand are alternative techniques to measure the SoA using the IB paradigm.  ...  However, these adaptations remain within visual cues on-screen. Therefore, in this paper, we propose a set of timing stimuli that employ auditory and tactile cues.  ...
