User experience comparison among touchless, haptic and voice Head-Up Displays interfaces in automobiles

Abstract

This paper evaluates driving experiences when using a Head-Up Display (HUD) system by different interaction methods, since HUDs in automotive market do not follow standard interaction methods (Betancur et al. in Int J Interact Des Manuf 12(1):199-214, [3]), and therefore it is difficult to identify what types of these methods are the most appropriated in terms of usability for being implemented in HUDs. This paper focuses on comparing the mental workload that a driver could experience while interacting with a specific HUD visual interface by touchless gestures, haptic or voice methods. Then, test subjects (n 15) performed conjointly a driving activity and a set of in-vehicle tasks by using these interaction methods throughout a HUD. The experiments show that the haptic method was better accepted than the touchless gestures and voice methods. Nevertheless, the touchless gestures method was explored under some specific usability configurations, in order to demonstrate that it was not significantly different from the haptic method. Keywords Head-Up Display • Human-machine interface • Vehicle 1 Introduction Regarding the authors' perspective, the Interactive approach concept explores different ways for interacting with a technical system, mainly looking for enhancing the user experience and performance. Consequently, this paper proposes a comparison among different interaction methods applied to a HUD system, in order to identify the best and worst qualities of every one of these from drivers' point of view. According to the above, the interactive development here

Localized Fretting-Vibrotactile Sensations for Large-Area Displays

“…Haptics has recently received much attention in studies on the multimodal interaction between human and virtual or augmented environments for teleoperation, − rehabilitation, − games, , training simulators, − automobiles, − and electronic devices. , Together with visual and aural sensations, haptic sensation can provide more intuitive and realistic interactions with displayed contents, such as object shape, texture discrimination, and object manipulation. , Providing an aural sensation with haptic and visual sensations is relatively easy because synchronization is enough to realize multimodality, and an audio system can usually be spatially separated from haptic and display devices . However, integrating haptic devices with high-quality display devices usually involves technological challenges because of spatial interference (e.g., haptic feedback on top of the displayed objects) and optical hindrance.…”
